It is no secret that South Asia is home to a vast and booming pharmaceutical market, one that is poised to serve more and more customers and patients both locally and far beyond its borders. Over the past several years, one of the fastest growing segments in the region is biologic drugs, which are used to treat chronic conditions because of their potential to offer patients better long-term outcomes and fewer side effects than traditional, chemical-based therapies. The biosimilar market is also growing driven by the fact that many biologics are scheduled to come off patent in the coming years.

And the shift is not going anywhere. According to the recent Quintiles IMS report, ‘Outlook for Global Medicines through 2021,’ pharmerging markets such as India will continue to be driven by non-original products over the next several years. At the same time, there is also a shift toward regulatory bodies in India and elsewhere across the Asia Pacific region increasing their focus on quality standards and lower particle burden for injectable drug products. Greater regulatory scrutiny and quality standards are placing added demands on drug manufacturers, suppliers and contract service providers. Motivated by concerns for patient safety, regulatory agencies in India and around the world are asking drug and packaging manufacturers to build quality into their products from the start to ensure consistent quality throughout a drug product’s lifecycle.

An evolving containment market

Given this increased focus on safety from regulatory agencies, pharmaceutical companies must now take a closer look at how they will contain their drug. For the majority of drugs, glass remains the preferred containment material. However, glass containment – while suitable for many drug products – can present compatibility challenges with biologics. Undesirable interactions include breakage, delamination, particulates in the suspension and design limitations that don’t allow for higher doses. The latter is relevant because biologic drugs are often made in larger doses and given less frequently.

Enter cyclic olefin polymers (COPs), which can be molded into a variety of shapes and designs. These systems can be designed to enable larger fill volumes and tighter dimensional tolerances, meaning manufacturers can optimize functionality and performance. The factors contributing to the increase of COPs include:

Breakage: A single dose of a biologic drug can cost hundreds or even thousands of dollars. And unlike chemical drugs, for which a 90% price drop can be seen for generic versions, biosimilars commonly cost only 20-30% less than their biologics counterparts. Given these prices, breakage in a clinic or at home presents not only a patient or employee safety issue, but also a major cost concern. Plastics solve that problem.

Supplying a global market: As regulatory agencies crack down on the safety of drugs and their delivery devices and South Asian biopharmaceutical manufacturers of biologics and biosimilars set their sights on supplying a more global market, it will be increasingly important to show regulatory agencies that quality measures are built into the products that deliver their drug. This quality assurance will be essential in order to become leaders in the biologic and biosimilar market. COPs help to address many of the concerns of glass containment for biologics and therefore provide an attractive alternative.

Cost: Problems with primary containment materials can result in delayed regulatory approvals, packaging variability and shortages of needed drug product on the market. All three problems can significantly damage a company’s bottom line as well as its reputation. But higher quality can come with higher investment, so the challenge for drug containment manufacturers becomes achieving the balance between managing the costs of provide higher-quality products while staying mindful of the customers’ total cost and profitability. Polymers can help companies to address this intersection of higher quality and improved overall cost.

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia.is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.
