One big positive has been the rapid strides that pharma and biotechnology companies worldwide made in the rapid development of vaccines and advanced device-based drug delivery systems.
Patients and caregivers are now more eagerly looking for advanced devices such as self-administered devices, smart wearables, and connected devices.
For examples
(a) Nanomaterial chemistry has enabled the development of smart stimuli-responsive drug delivery systems that can ensure spatial or temporal, on-demand drug delivery to a targetted site
(b) Connected drug delivery devices provide new capabilities that are never seen on the market like remote control of the drug delivery including programmable delays at the start, managing complex dose rates and dosing regimens from more than one drug container, or even more than one delivery device and connection with diagnostics.
The nano-based drug delivery systems will gain more traction in the drug delivery devices market due to their ability to offer multiple benefits in treating chronic human diseases by site-specific and target-oriented delivery of precise medicines. These systems can increase the cellular uptake of drugs because of the surface charge and they can increase the stability and water solubility of drugs.
There are several path-breaking applications of nanomedicine (chemotherapeutic agents, biological agents, and immunotherapeutic agents) in the treatment of various diseases on the horizon.
Leveraging our expertise and resources to tackle the worst public health crisis was the biggest learning and victory
Agile ways of working has been one of the biggest lessons learnt from the pandemic. This was amply demonstrated with the fast track development and approval of safe and effective COVID-19 vaccines. Leveraging our expertise and resources to tackle the worst public health crisis was the biggest learning and victory.
We also witnessed a rush to repurpose existing drugs for the treatment of COVID-19. These learnings need to be taken forward to identify novel clinical use to explore treatment options for newer indications. There is a solid knowledge base and safety data of existing molecules and this can help to considerably reduce the drug development process, cost and the time.
COVID-19 has led to significant geo-economic and geopolitical shifts. There is a major thrust on self-sufficiency in all the major economies of the world. There needs to be renewed focus on developing capabilities in the API manufacture, complex generics, biosimilars, gene and cell therapies. This will reduce our dependence on other countries and help us address larger global markets.
The pandemic has compelled organisations to think more creatively to overcome bottlenecks. The extraordinary circumstances has undoubtedly hastened the digital disruption and forced to think outside the box. Many organisations have partnered with AI startups to look for drug candidates for a range of diseases. AI is also put to use to build more robust processes to avoid human errors and increase manufacturing output.

These capsules contain plant-based ingredient beadlets to give the body sustained nutrition over a longer period. They embody the delayed-release technology that is designed to dissolve slowly over eight hours, protecting the nutrients from the stomach acid and ensuring their proper and most effective absorption. The two-in-one capsule i.e. the capsule in capsule formula ensures a powerful dose of all nutrients, minerals and compounds with the effective absorption benefits of fast-acting oils and slow-release beadlets.
COVID has accelerated research in inhaled drug delivery
It is time to have a look at the fallout of COVID-19 on drug therapy. The incredible power of vaccines and monoclonal antibodies are among the most striking features. The vaccines protect not just against COVID-19 but shingles, hepatitis, and many other preventable diseases. Vaccines don’t save lives, vaccinations do. The mega vaccination drive against covid worldwide has vindicated this.
Among different platforms employed for vaccine development, mRNA technology offers the greatest promise. The technology, though not new, burst onto the global scene to take on COVID-19, and this in turn, encouraged researchers to harness technology to tackle the three deadliest infectious diseases – tuberculosis, malaria and HIV.
WHO holds that technology can also be used for non-communicable diseases like diabetes and cancer.
The advantages include ease of development, adaptability to variants, scalability, stability, etc, particularly with advancements in the synthetic production of mRNA. Diversifying mRNA vaccine manufacturing capacity in different countries should be a global health priority.
COVID has accelerated research in inhaled drug delivery where lung biology interfaces with an inhaler that allows optimum delivery of drugs for specific disease management.
The potential utilisation of nanocarriers for biomimicry and/or targeted delivery of bioactives to cells is being explored to improve therapeutic outcomes.
Scientists at MIT recently have developed a capsule that can deliver 150 mcg of RNA more than mRNA used in the COVID vaccine in the stomach of pigs raising hopes of delivering RNA and DNA therapeutics orally and enhancing patient acceptance.
Lipid-based delivery should be harnessed to treat NCDs
The COVID-19 pandemic disrupted lives bringing the world to a standstill. However, it also made healthcare a priority for everyone. For the pharma companies, it led to a worldwide consensus that drug delivery strategies needed to be changed significantly. Manufacturers and policymakers realised that innovations in drug delivery technologies have to be effective, affordable, accessible and available on a global scale. One of the lessons from the pandemic was how ingredients like lipids played a crucial role in vaccine delivery systems and therefore the need to focus on such technologies to ensure a robust vaccine supply chain.
Lipid-based delivery is one of the powerful, sustainable tools and should be harnessed to treat different non-communicable diseases. Drug delivery strategies and technologies developed during the pandemic can be applied to new therapeutic modalities that can be adapted to improve the delivery of older therapeutics. Industry and government should use the lessons from the pandemic to work together to advance healthcare. Last but the most important lesson we learnt is to respect, care, help, support, protect, value and appreciate life.
