Small Molecule API Market Size, Demand & Forecast 2033 | FMI

The global small molecule API market is on the brink of a significant breakthrough, with projections indicating a surge in revenue from US$ 116 billion in 2023 to an impressive US$ 174 billion by 2033. This trajectory is underpinned by an anticipated Compound Annual Growth Rate (CAGR) of 4.1% throughout the forecast period.

A small molecule drug can enter cells easily because it has a low molecular weight. Once inside the cells, it can affect other molecules, such as proteins, and may cause cancer cells to die. Increasing research on small molecule APIs and novel Biologics APIs will boost the market growth. The high-potency drug market is a growing pharmaceutical segment. The increasing prevalence of cancer and other chronic diseases owes to the need for oncology drugs and antibody-drug conjugates.

Germany will account for the maximum sales in Europe. Besides this, the demand from France is expected to rise
Increasing investment in research and development within pharmaceuticals will drive sales in China

The use of external resources (people, equipment, and/or expertise) to facilitate the preparation of Active Pharmaceutical Ingredients (API) or advanced intermediates has become a common practice for most pharmaceutical development organizations. In early development, the reasons to seek external support for the manufacture of API were attributed to a number of factors, including a lack of sufficient internal capacity, a need to source unique technical expertise, or a desire to achieve overall cost reductions.

For organizations that have no internal GMP manufacturing capabilities whatsoever (e.g. biotech companies), outsourcing is, of course, a necessity. However, companies that have some level of internal manufacturing capacity may have options to use outsourcing to their strategic advantage. This outsourcing capability has increased the source of generating more revenue for new emerging companies. For the fast growth of the industry, they follow outsourcing strategies.

In addition, key players in the Small Molecule API market are keenly focusing on carrying out strategic activities such as advanced technology for manufacturing, and acquisitions, in order to create a strong position in the market is leading to vigorous developments which is helping the market to grow at a considerable rate.
