Europe’s drug supply chain gets ready for a makeover

C&EN, 20 May 2019

As the European Commission prepares a new pharmaceutical strategy, manufacturers seek financial support and technology investment

When the COVID-19 pandemic exposed weaknesses in the pharmaceutical supply chain in the US—in particular its dependence on products outsourced to Asia—the government responded forcefully. The Trump administration led with an initial grant of $354 million, with a possible $458 million to follow, for a newly formed company, Phlow, dedicated to manufacturing critical active pharmaceutical ingredients (APIs) domestically.

Next came a letter of intent for a $765 million loan to Eastman Kodak to convert a specialty chemical plant at the company’s headquarters in Rochester, New York, into an API manufacturing complex dedicated to “reshoring” pharmaceutical chemicals from China and India.

Now it’s Europe’s turn. The European Commission (EC) has been studying the global supply chain, setting itself a year-end deadline for delivering a drug and health-care strategy. Proposed road maps solicited by the EC from manufacturers of APIs and finished drugs illustrate differences between the US approach and Europe’s possible path to self-sufficiency in pharmaceutical manufacturing.

In a meeting in April with the European Union conference of presidents, the EU’s health and food safety commissioner, Stella Kyriakides, raised the matter of supply chain vulnerabilities exposed by the COVID-19 pandemic. Kyriakides cited “structural weaknesses in the EU’s medicines supply chain and a high dependence on non-EU countries for active pharmaceutical ingredients” and recommended that supply chain issues be addressed in an EU strategy. The EC solicited public comment on the proposed strategy in June.

Judging from the recommendations put forward by European associations representing drug and pharmaceutical chemical firms, the commission’s approach will differ significantly from the tack taken by the outgoing Trump administration. Rather than spending millions of euros launching made-in-Europe ventures, the EC will likely leverage a sizable established manufacturing base. Likewise, industry guidance for Europe’s plan places greater emphasis on making its supply chain more secure rather than less global, while maintaining and expanding the region’s manufacturing footprint.

Adrian van den Hoven, general director of Medicines for Europe, an association of generic-drug and API makers, stresses that reshoring cannot be viewed as simply resuming the manufacture of products that have been outsourced to China and India. “It’s a question of making it sustainable to invest and continue to invest in Europe,” van den Hoven says. “We still have a pretty robust industrial footprint in Europe, with a lot of capabilities.” But growth has flattened in recent years, he adds, as manufacturers in countries like India have taken market share.

Luis Gomes, second from left, with his production management team, advocates selective reshoring and investment in technology.

 

Medicines for Europe’s proposals to the EC include a change to generic-drug pricing, which individual countries currently set at the lowest possible levels to reduce the cost of subsidized health care. The association proposes a scheme that would allow prices to be negotiated from the bottom up based on a supplier’s cost of goods, regulatory costs, and other considerations.

For hospital and retail purchases, van der Hoven says Medicines for Europe favors “multi-winner tenders,” in which buyers are required to purchase from several suppliers as opposed to awarding contracts to the lowest bidder, a practice that has fueled consolidation among drug suppliers.

The group also advocates government support for technology development. Van den Hoven points to Europe’s almost $900 billion COVID-19 recovery package, “The commission has made it clear that some of the funding will be available for technology investment by our sector,” he says.

Medicines for Europe also advocates global coordination of drug supply as opposed to rampant reshoring. “It is important that we maintain critical technologies in Europe,” van den Hoven says. “That said, we don’t believe we can or should produce everything in Europe.”

That view is seconded by Luis Gomes, senior vice president of operations at the Portuguese API firm Hovione. He’s also chairman of the Pharmaceutical Activities Committee of the European Fine Chemicals Group (EFCG), an industry association.

“I think the commission has an understanding that it needs to strengthen the production of pharma products in Europe in order to reduce the dependence and vulnerability of the supply chain,” Gomes says. “I think regulators need a kind of road map to pursue what I would call meaningful pharmaceutical production reshoring in Europe. That starts with priorities.”

The EC must arrive at a list of critical APIs that need to be manufactured in Europe, Gomes says. Those no longer made in Europe can be reintroduced, thus increasing the domestic manufacturing base. “And it’s not only APIs one cares about,” he says. “You are also dependent on supply of intermediates and building blocks. You need to look at the supply chain from an end-to-end perspective.”

Pharmaceutical chemistry presents a significant hurdle given that many of the reactions involved have disappeared from Europe in the wake of the region’s Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) legislation and other environmental tightening over the past 2 decades. For example, REACH required expensive environmental controls on reactions such as nitration, fluorination, and bromination, which are critical to making certain drug ingredients. “I think REACH created an incentive for production of these chemicals to move to other places, especially Asia, but that doesn’t mean they cannot be manufactured again in Europe,” Gomes says.

Like Medicines for Europe, EFCG sees a need for the government to invest in green technology. Financial support will also be needed to establish European production of critical drugs and drug ingredients now made exclusively overseas.

Maggie Saykali, director of resins and fine chemicals at the European Chemical Industry Council (Cefic), says in an email that her trade association also has been in discussions with the EC regarding vulnerabilities in the pharmaceutical supply chain. Cefic is preparing a report with recommendations at the commission’s request.

“One of the pillars of our roadmap is selective reshoring of the critical technologies needed for the molecules for which long-term supplies must be guaranteed,” Saykali writes. “In order to be sustainable in the long run, this selective reshoring needs support for process innovation, expansion of existing EU production facilities and enforcement of a level playing field for the highest-quality safety, environmental, and social standards.”

Sources agree that continuous manufacturing technology will play a role in developing efficient and green manufacturing. They also agree that the Research Center of Pharmaceutical Engineering’s Center for Continuous Flow Synthesis and Processing (CC Flow) initiative at Graz University is the center of continuous technology development in Europe.

C. Oliver Kappe, scientific director of CC Flow, says that his lab is not communicating directly with the EC on the development of a reshoring strategy but that several of its partners are contract manufacturers and members of associations such as EFCG. Kappe says the lab plans to set up a facility near Graz, Austria, that will pilot the manufacture of both APIs and finished drugs in a fully continuous fashion.

Continuous manufacturing could help avert crises such as drug shortages during pandemics in Europe, Kappe argues. He notes that CC Flow has worked on a process for manufacturing remdesivir, a COVID-19 treatment developed by Gilead Sciences. It also has collaborated with a similar center in the US, the Medicines for All Institute at Virginia Commonwealth University. Medicines for All is a partner in Phlow, the company launched by the Trump administration to repatriate generic drugs.

While Europe has taken a few pages from the US response to the COVID-19 pandemic—the EU recently announced it would create a biomedical research agency comparable to the Biomedical Advanced Research and Development Authority, the US government agency that launched Phlow—the European path will inevitably differ. Observers note that Brussels is coordinating 27 independent countries’ efforts, ensuring a more protracted process than experienced in Washington.

One EU country has floated a Phlow-like venture with a view toward securing domestic supply of acetaminophen. The government of France is sponsoring a partnership with the French drug firms Sanofi and Upsa and the French API maker Seqens to establish domestic supply of the analgesic, which currently comes mostly from China. Seqens manufactures bulk acetaminophen there. Upsa and Sanofi manufacture most of the finished drug used in France, but they source API from China. The plan, still at a preliminary stage, would have Seqens add capacity for the API in France.

Van den Hoven at Medicines for Europe likes the hospital and health-care-facility purchasing strategy adopted by Phlow and its partner Civica Rx, a nonprofit launched in 2018 to help manage generic-drug prices and prevent shortages for member institutions. But he questions the US government’s decision to spend up to $800 million establishing a new company to foster domestic manufacturing of APIs.

“It’s an incredible amount of money,” he says. “In Europe, we can do it for a lot less.” He points to Sandoz’s deal with the Austrian government to invest more than $175 million at its site in Kundl, Austria, Europe’s last large antibiotics plant. “This is really small change for a production site that supplies half of Europe with penicillin,” van den Hoven says.

On Nov. 25 the EC issued its Pharmaceutical Strategy for Europe, which outlines a raft of initiatives the commission will put forward for approval by the European governing bodies. The strategy, which is not finalized, addresses many of the manufacturing issues raised by industry associations, including pricing policies and investment in green technology. But it lacks details on regulatory changes impacting the use of continuous process manufacturing, and it does not suggest the creation of a list of critical APIs. Van den Hoven says the commission is still fielding input from industry pending a finalized plan.

Europe’s drug manufacturers are awaiting further direction from the EC just as the world braces for a surge in COVID-19 infections that may reignite supply chain anxiety. Van den Hoven notes, however, that the first wave of the pandemic was marked by a cooperative response globally. For instance, Europe expedited the export of drugs used in intensive care units to the US despite crisis-level demand for the same drugs at home, he says.

“The political climate is a little tense right now,” van den Hoven says. “But at some point people are going to have to go back to cooperation again.”

The podcast "The Next Discovery" is a six-episode series created by Observador, a leading Portuguese digital newspaper and radio station, in partnership with Hovione. From factory to pharmacy in far less time: how continuous tablet manufacturing is making treatments faster, more robust, and more accessible to those who need them most. What if some of the scientific breakthroughs that could improve the lives of millions of people were happening right now in Portugal? Welcome to The Next Discovery. Listen to the fourth episode of the podcast here, featuring João Ventura, Senior Director of Pharmaceutical Product Development at Hovione. [English transcription] Nelson Ferreira (NF): Welcome to The Next Discovery. This is a partnership between Rádio Observador and Hovione—a six-episode series in which we open the doors to global pharmaceutical development driven from Portugal. I’m Nelson Ferreira, and today we’ll explore a technology that is transforming the way medicines are produced and accelerating patient access to new treatments. To guide us on this journey, we’re joined by João Ventura, Senior Director of Pharmaceutical Product Development at Hovione. NF: Hello, João, and welcome. For decades, the industry relied on what is known as batch manufacturing. How did this traditional method work, and why does continuous manufacturing represent such a significant change for the pharmaceutical industry? João Ventura (JV): Thank you, Nelson, for the invitation and for that question, which is a great place to start discussing this innovation. As you mentioned, for many decades the pharmaceutical industry produced tablet medicines using the traditional batch manufacturing method. This approach involves producing a very specific quantity of product—a batch—at a time and performing each individual production step separately. This means that each subsequent step typically begins only after the entire batch from the previous stage has been manufactured, processed, collected, and sampled for quality verification. In tablet production, the process includes weighing, blending, granulation, tablet compression, and finally tablet coating. While this method is well understood, mature, and fully established from both an industrial and regulatory standpoint, it can become inefficient because material may spend a considerable amount of time sitting idle between production stages—waiting for quality checks or for equipment in the next step to become available. By contrast, continuous tablet manufacturing allows material to move continuously and automatically through all stages of the process while simultaneously monitoring the quality of the tablets being produced. This enables continuous manufacturing to deliver benefits that traditional batch manufacturing simply cannot achieve. NF: João, producing continuously certainly sounds more logical, but as I understand it, this is still a relatively new technology in the pharmaceutical industry. When did the market begin to embrace this change? JV: You're absolutely right, Nelson. As you know, the pharmaceutical industry is necessarily conservative and adopts innovation very carefully, for good reason. It was only in the early 2000s that the U.S. Food and Drug Administration (FDA) began encouraging the industry to develop alternative technologies that were both more agile and more robust from a quality perspective. These technologies are based on integrating and automating the entire tablet manufacturing process in a continuous flow. This required the development of a new generation of manufacturing equipment capable of performing the entire process automatically and continuously, as well as sophisticated electronics and software to monitor and inspect product quality throughout intermediate stages and in the final tablet. Following these early technological developments, the FDA approved the first continuously manufactured products from major pharmaceutical companies such as Vertex and Janssen during the 2010s. This marked a pivotal turning point and significantly accelerated adoption of continuous tablet manufacturing. NF: What practical challenges does this new system solve in day-to-day operations? I imagine there are important quality-control advantages as well, especially since you mentioned quality can be assessed throughout the process and in the final tablet. JV: Absolutely. The successful commercialization of that first wave of continuously manufactured medicines by companies such as Vertex and Janssen was extremely important because it demonstrated to the industry that this technology could deliver substantial benefits for both patients and manufacturers. First, it shortens development and production timelines for new medicines, allowing innovative therapies and new drug products to reach patients much faster than before. NF: So they can reach the market sooner as well. JV: Exactly. In addition, as you mentioned, this technology makes it possible to verify the quality of every tablet produced, rather than relying on a small sample as in batch manufacturing. That alone provides greater quality assurance and robustness, ultimately benefiting society as a whole. NF: And does that speed advantage become particularly important during medical or public health emergencies? Can this system respond more quickly to urgent demand? JV: Yes, that is one of the technology’s most significant potential advantages. In a continuous process, it’s possible to produce in minutes what might take weeks in traditional batch manufacturing due to processing delays and waiting times. Beyond the economic benefits, this offers a major advantage in medical or public health emergencies, where production of new medicines may need to be rapidly scaled up to meet urgent demand. NF: Was COVID-19 an example of that? JV: It’s a perfect example. NF: Has this technology already delivered that benefit? JV: Not yet, but we anticipate that in future pandemic situations, continuous manufacturing will play a critical role in scaling industrial production much more rapidly, much as we saw with the need to rapidly expand vaccine production. NF: Hovione positioned itself as a global pioneer in this technology, largely through a strategic partnership with Vertex that you mentioned earlier. This happened in 2016. How did a Portuguese company become the first of its kind to adopt such an important industrial-scale advancement in the United States? JV: Since its founding, Hovione’s history has been closely linked to the adoption and application of new pharmaceutical manufacturing technologies capable of delivering significant industrial and economic advantages. That has been one of the company’s keys to success. During the 2010s, Hovione recognized the potential and benefits of continuous tablet manufacturing early on. As you mentioned, in 2016, Hovione entered into a strategic partnership with Vertex to establish industrial-scale continuous tablet manufacturing capabilities in the United States. Hovione was likely the first company of its kind to adopt this technology. This was important not only for industry-wide adoption but also because, in partnership with Vertex, it played a key role in developing a new, more effective treatment for cystic fibrosis—a devastating, currently incurable disease that primarily affects children. NF: Earlier, you mentioned that this represented a significant industrial challenge. I imagine it required designing and installing far more sophisticated equipment to make it all work. JV: That's correct, Nelson. The challenges were enormous during the first industrial-scale implementation of continuous tablet manufacturing. Hovione’s team led the project from the initial facility and equipment design stages all the way through construction of the building, installation of the new equipment, and operational execution of the manufacturing process for this new Vertex medicine, which has played an important role in treating a serious and incurable disease. NF: After that first facility in the United States, this technology was also brought to Portugal, to Loures, where Hovione has operated a second production line for several years. Does this, in a way, complete the cycle for Hovione, allowing the company to work from molecule to finished tablet? JV: Exactly. Following the success of the first industrial installation and the experience gained, and driven by growing market demand and interest in the technology, Hovione expanded its manufacturing capacity in the early 2020s by building and commissioning a second continuous tablet manufacturing facility at its Loures site in Portugal. As you noted, the Loures facility is capable of performing the entire development cycle—from chemical production of the innovative molecule through formulation and manufacture of the final tablet. NF: João, we’re speaking at a time when global soccer competitions often inspire national pride. I imagine there’s also a sense of pride when patients anywhere in the world take an innovative medicine knowing that the engineering and technology behind it involved Portuguese teams. JV: Absolutely, Nelson. By combining our ability in Portugal to identify and adopt innovative technologies with investments in advanced manufacturing capabilities, we can position ourselves as trusted partners to our customers across our industries. That has certainly been the case with Hovione. As you mentioned, we have helped produce innovative medicines that improve the quality of life of millions of people around the world. That should be a source of pride for all of us here in Portugal, just as our national soccer team is. NF: João, thank you very much for explaining how this technology is challenging traditional manufacturing and accelerating the production of life-saving medicines. João Ventura is Senior Director of Pharmaceutical Product Development at Hovione. That concludes the fourth episode of The Next Discovery. In the coming weeks, we’ll explore a new topic: how the respiratory and nasal systems can be used to deliver medicines more effectively to the lungs and, in some cases, even serve as a direct highway to the brain.

Podcast “The Next Discovery” (EP4) - Continuous Tablets, Lives in Motion

Jul 09, 2026

The podcast "The Next Discovery" is a six-episode series created by Observador, a leading Portuguese digital newspaper and radio station, in partnership with Hovione. From particle engineering to global leadership in spray drying, discover the technology that enables oral medicines to be effectively absorbed by the body and help treat millions of people. What if some of the scientific breakthroughs that could improve the lives of millions of people were happening right now in Portugal? Welcome to "The Next Discovery. Listen to the third episode of the podcast here, featuring Filipe Gaspar, VP Technology Intensification, and José Luís Santos, Strategic Business Management Senior Director, at Hovione. [English transcription] Nelson Ferreira (NF): Welcome to The Next Discovery. This is a partnership between Rádio Observador and Hovione, a six-episode series in which we show how science developed in Portugal has a real impact around the world. I’m Nelson Ferreira, and in the last episode we explored how APIs—the active pharmaceutical ingredients in medicines—are produced. Today, we move to the next stage: how do we transform that chemical powder into a medicine that our bodies can actually absorb? To help explain this science, I’m joined by Filipe Gaspar and José Luís Santos, who were involved in the creation and development of Hovione’s particle engineering division. Welcome to you both. Filipe, let me start with you. NF: When we hear about a new medicine, we usually think about the molecule that was discovered. But why isn’t that discovery alone enough? What exactly is particle engineering, and what role does it play in turning a promising molecule into a medicine that is truly effective? Filipe Gaspar (FG): Nelson, the active ingredients in many modern medicines are not effective in the form in which they are produced through chemical or biological processes. To work properly in the body, they need to undergo additional transformations. For example, some medicines must be protected from the acidity of the stomach so they can later be released in the intestine, where the environment is less acidic and absorption into the bloodstream can occur. Others require very specific particle sizes. This is the case with inhalation powders, often used to treat asthma or chronic bronchitis. If the particles are too large, they become trapped in the upper airways and never reach the alveoli, where they need to be absorbed. On the other hand, if they are too small, they may simply be exhaled before absorption occurs. Finding the right particle size is therefore essential to ensuring an effective treatment. Another remarkable example is modern oral medicines, which often need to be converted into a different form—the amorphous form—so that the body can absorb them properly. Particle engineering makes all of this possible, overcoming many of these limitations by improving drug absorption, distribution, and therapeutic effectiveness. NF: I believe that in 2003 Hovione made a bold decision and invested in spray drying technology. José, for our listeners, could you explain in simple terms what this technology is, what problem it solves, and why it was so revolutionary at the time? José Luís Santos (JLS): First, it’s worth noting that spray drying has been used for decades in other industries. Think, for example, about powdered milk, instant coffee, or the powdered detergent we use in our washing machines. In all these cases, we start with a liquid—milk, coffee, or a soap-based paste—and transform it into a very fine powder that dissolves almost instantly when mixed with water. This transformation is achieved through spray drying. To explain it simply, imagine a very large chamber, something like a giant hair dryer. Inside, the liquid we want to dry is converted into a spray—a kind of mist—creating extremely small droplets. These microscopic droplets are then dried very rapidly using hot gas inside that giant dryer. In just milliseconds, the liquid evaporates, leaving behind a powder made of tiny particles with properties that, as Filipe mentioned, make them highly soluble. The powders we produce in the pharmaceutical industry are physically similar to powdered milk, instant coffee, or powdered detergent. Now, why was this technology revolutionary for pharmaceuticals? Just as spray drying made it possible to preserve milk for months without refrigeration or gave us coffee that can be prepared in seconds, pharmaceutical spray drying made it possible to create medicines with improved therapeutic effectiveness because they became more soluble. Without access to spray drying technology, many of these medicines would simply not have had a viable path to reach the market and ultimately patients. NF: Filipe, we now have a better understanding of what happens in the factory, but I’m curious about what happens inside a patient’s body. Can you give us some concrete examples? What happens when a molecule looks promising in the laboratory, but the body cannot absorb it effectively? FG: Of course. As surprising as it may sound, most medicines taken orally—tablets and capsules—are actually less soluble in water than glass or marble. Since our gastric and intestinal fluids consist primarily of water, these medicines, in their original crystalline form, dissolve very poorly and can pass through the digestive system without being absorbed into the bloodstream. That would make them completely ineffective. Spray drying solves this problem by transforming them into an amorphous form that dissolves much more easily and can be absorbed by the body. A simple analogy would be to compare an ice cube with snow. Both are solid water, but snow melts much faster because of its structure. Spray drying applies a similar principle to medicines, significantly enhancing their ability to dissolve and be absorbed. NF: José Luís, some of this may sound very technical to our listeners, but the outcome is ultimately that people live longer and healthier lives because of these technologies. Are there concrete examples of medicines that only reached the market and patients because of this technology? JLS: Absolutely. One of the most significant examples involving Hovione was the COVID-19 treatment effort. Hovione participated in the production of Captisol, a compound that was essential in the manufacture of Remdesivir, Gilead’s antiviral medicine, which became one of the few treatments authorized for COVID-19. Another important example is the treatment of hepatitis C. Around 10 to 12 years ago, the disease was virtually eradicated in many parts of the world thanks to new medicines whose manufacturing processes relied on spray drying technology. This enabled those therapies to achieve the solubility and therapeutic effect required. These are just two examples. At Hovione—and across the industry—we are working with a growing number of medicines, including treatments for oncology, cystic fibrosis, and many other diseases that benefit from spray drying technology and the advantages it offers. NF: From what I understand, this technology will continue to play an important role in future discoveries as well. Filipe, when Hovione invested in spray drying, it was a technology that was almost inaccessible and rarely used in the pharmaceutical industry. What did Hovione see that others didn’t? And how did what seemed like a risky bet eventually position the company as a global leader in this field? FG: When we invested in the technology in 2003, we had already identified one or two opportunities. As you said, it was a technology that was practically nonexistent among companies like Hovione that provide services to the pharmaceutical industry. We decided to invest before there was established market demand, which meant taking a significant risk. We were talking about many millions of euros—the cost of an industrial-scale spray dryer. Afterward, we actively developed the market. The demand we saw, particularly the need to improve the bioavailability of oral medicines, confirmed our highest expectations. We have made—and continue to make—ongoing investments in science, technology, and industrial capacity. Over the years, these investments have consolidated Hovione’s position as a global reference in spray drying. Now, we must continue innovating to maintain that position. NF: Based on the examples we’ve been hearing, that doesn’t seem likely to be a problem for Hovione. We also know that innovation doesn’t happen in isolation. Spray drying appears to be another example of that. Hovione seems to have strong ties with academia and universities through master’s and doctoral programs conducted in industrial settings. Is this collaboration the secret to staying at the forefront? JLS: Yes. Our connection with academia has always been very important and continues to be so. Today, we have more than 300 people working in research and development roles, and we maintain strong ties with the academic community. Hovione is one of the largest private employers of PhDs in Portugal, with approximately 120 PhDs on staff, and we actively promote projects in partnership with universities and research centers. FG: I would also like to mention the Hovione Research Program. NF: What is that? FG: It is Hovione’s research program. It is a collaborative initiative with Portuguese academic institutions and has been active for more than 15 years. To give you an idea, at any given time we typically have around 10 PhD candidates and between 20 and 30 master’s students conducting their work in an industrial environment simultaneously. Most of these researchers end up joining Hovione after completing their studies, integrating into the same areas in which they carried out their research. They are a reflection of this collaboration with academia, which has been a key driver not only of our ability to innovate but also of our capacity to attract and retain highly qualified talent. NF: Filipe Gaspar and José Luís Santos, thank you both for showing us that behind every medicine there is an enormous amount of science, innovation, and talent. And often it is invisible technologies—such as the spray drying technology we discussed in greater detail today—that make a difference in the lives of millions of people. This concludes the third episode of The Next Discovery. Next week, we take the next step and discover how Hovione challenged industry tradition by introducing continuous tablet manufacturing.

Podcast “The Next Discovery” (EP3) - Particles that change lives

Jul 02, 2026

The podcast "The Next Discovery" is a six-episode series created by Observador, a leading Portuguese digital newspaper and radio station, in partnership with Hovione. From hard-to-produce antibiotics to innovative therapies, Hovione uses complex and sustainable chemistry to bring safe medicines to patients around the world. What if some of the scientific discoveries that could improve the lives of millions of people were happening right now in Portugal? “The Next Discovery.” Listen to the second episode of the podcast here, featuring Rui Loureiro, scientist at Hovione. [English transcription] From hard-to-produce antibiotics to innovative therapies, Hovione uses complex and sustainable chemistry to bring safe medicines to patients around the world. What if some of the scientific discoveries that could improve the lives of millions of people were happening right now in Portugal? “The Next Discovery.” Nelson Ferreira (NF): Welcome to the podcast “The Next Discovery.” This is a partnership between Rádio Observador and Hovione—a six-episode series where we open the doors of a Portuguese-founded multinational pharmaceutical company to share real stories of science, innovation, and global impact. I am Nelson Ferreira, and in the first episode we explored the story of the basement where it all began more than 65 years ago. Today, we will understand what happens inside this company. We will talk about complex chemistry, because that is where the journey of many medicines that pass through Hovione begins. We will discover how laboratory science becomes industrial processes, how sustainability is part of this transformation, and how all of this contributes to producing medicines that truly help improve and save lives. To guide us on this journey, I am joined today by Rui Loureiro, a scientist at Hovione’s Research and Development Center. Hello, Rui. Welcome to Rádio Observador. NF: Rui, most people may never have heard of Hovione, but they may be taking a medicine where Hovione played an important role. Where exactly do you fit into this long journey that takes a medicine to the patient? Rui Loureiro (RL): Hello, Nelson, good morning—and thank you for the question. The path for a medicine to reach a patient is long. It starts with producing a very small amount of a drug, which through development eventually needs to be produced in kilograms. Let me give an example. Imagine baking cookies. When you buy cookies at the supermarket, someone first made the initial batch at home—but then they needed a partner to scale those cookies to an industrial level. NF: A factory, exactly. RL: Exactly. That is where Hovione comes in. We are that partner for the pharmaceutical industry—helping turn one cookie into many cookies that eventually reach patients. NF: For those listening who are not familiar with this field, people often talk about APIs in the pharmaceutical industry. I had to look it up myself. What is it, and why has Hovione focused so much on it since early on? RL: API can mean different things depending on the field—for example, in IT it means something entirely different. In the pharmaceutical industry, API stands for Active Pharmaceutical Ingredient. In Portuguese, princípio ativo—the component that treats or cures the disease. Using the cookie analogy again: a chocolate cookie has many ingredients—but the chocolate is what defines it. The API is exactly that in a medicine: a small but essential part that delivers the therapeutic effect. Even though tablets contain multiple substances, producing something like a 10 mg tablet of the active ingredient alone is difficult—so other components are added to create the final form. NF: Over many years, Hovione also specialized in complex generics. How did that experience help you move into working with companies developing entirely new medicines? RL: That was a very important step. Developing complex generics means the chemistry required is challenging—it may involve very low temperatures or tightly controlled conditions to ensure we produce the desired result and not something unwanted. Those early capabilities—developing antibiotics and other materials—led the market to recognize Hovione’s expertise. Ultimately, chemistry involves combining building blocks. If someone proves they can assemble the most complex ones, the industry will take notice. That is how we became recognized as a trusted partner for complex pharmaceuticals. NF: I am curious about this idea of “complex chemistry.” You often compare chemistry to cooking—what distinguishes traditional chemistry from the complex chemistry you do at Hovione? RL: Let me simplify for clarity. Complex chemistry depends on the reagents and solvents used. The starting materials may be difficult to transform and may require very specific conditions. The resulting product may also be unstable and require careful handling. Using cooking as an analogy: simple chemistry is like making jelly—you mix powder with hot water and let it set. Complex chemistry is more like making ice cream—it involves a more intricate process, and many people prefer to leave it to specialists. NF: Another fascinating challenge: in the lab, you work at milligram or gram scale, but factories must produce tons. How do you scale from a teaspoon to a truckload without ruining the recipe? RL: That is indeed our biggest daily challenge. Scaling up requires understanding every variable in the process. Going from a small kitchen setup to industrial production is not just about bigger equipment—it requires entirely different systems and expertise. We work with multidisciplinary teams—chemists, engineers, analytical specialists—to control every variable that affects product quality. In a typical GMP (Good Manufacturing Practice) process, there are 4–5 main steps. And across those steps, we may need to control around 350 variables to ensure the final product meets quality standards for patients. NF: When people think of chemistry, they often think of something negative. But Hovione has been developing more sustainable approaches. What does sustainable chemistry mean in practice? RL: Sustainability is a daily priority. We design processes with sustainability in mind from the very beginning. We follow green chemistry principles—avoiding harmful reagents whenever possible. And when that is not possible, we apply the “four Rs”: reduce, reuse, recycle, and recover. For example, just as the paint industry moved from solvent-based to water-based systems, we are also moving toward chemistry in water. This reduces the carbon footprint of our processes. We are also exploring micellar chemistry, flow chemistry, and even reactions without solvents at all—similar to grinding ingredients together with a mortar and pestle. These approaches help reduce waste and improve efficiency. NF: Looking to the future—will chemistry remain our best tool to save lives, and in a more sustainable way? RL: Absolutely. That is what motivates me every day. Artificial intelligence is already helping identify targets and design molecules—but those molecules still need to be produced. That is where chemistry remains essential. It is the foundation for creating and improving medicines. Innovation and sustainability will go hand in hand—and that is the path we are committed to. NF: Rui Loureiro, thank you for helping simplify chemistry and for showing this more sustainable side of science. This was the second episode of “The Next Discovery.” In the coming weeks, we will continue exploring this world. In the next episode, we will look at the future of particle engineering.   You can listen to the next episodes on observador.pt and on your usual podcast platform.

Podcast “The Next Discovery” (EP2) - Complex chemistry, real impact

Jun 25, 2026
