The market for rapid-acting insulin is dominated by three companies: Sanofi, Novo Nordisk, and Eli Lilly. Each of these companies has built its brand name in the marketplace. To access the local markets, however, these firms must exert substantial effort due to the severe competition there. Consequently, they utilise powerful competitive techniques to bolster their market position. Motivated by the market's high profitability, numerous generic insulin (biosimilars) manufacturers and significant firms striving to launch unique goods are abundant. This is why the demand for short-acting insulin attracts the attention of substantial business people seeking to enter a lucrative market.
