Research agency Espicom estimates the global generics injectables market at $12.2 billion. This, of course, is quite small considering the mammoth size of the global pharmaceutical industry (the worlds largest drug-maker Pfizers 2013 revenue alone was close to $52 billion), but the growth potential is seen to be big. Some of the injectable products like those in oncology segment also offer very attractive margins of 75-80%, which is why generic drug companies are eyeing this market with new-found vigour. Shortage of injectables in the US market is adding to the trend.
The $100-billion US branded-drug market will lose patent protection by 2018 as a patent cliff is approaching. Generic players see great scope in this unravelling of patents, not only in conventional chemical drugs but also in complex biologics, vaccines, etc, many of which belong to the injectables category.
The recent spate of deals in the injectables segment would find foreign and Indian firms among aggressive acquirers. Lupin Laboratories bought Dutch injectables maker Nanomi on February 4 in one of the latest such buyouts in the space.

Injectables is already showing its importance, with Dr Reddys US revenue in three quarters of 2014 fiscal seeing a strong growth, helped by niche injectable launches.

In what reflects the shortage of injectables in the highly regulated markets, Johnson & Johnson could not supply the chemotherapy drug, Doxil (doxorubicin) from October 2013 in the US due to issues with its manufacturing partner, Boehringer Ingelheim. India's Sun Pharma came to the rescue with the generic version of the drug. The growing significance of the injectable for top Indian companies is evident as doxorubicin, indicated for ovarian cancer and multiple myeloma, contributed about 11% to Sun Pharma's Q3FY14 revenue. With J&J still unable to get its drug to market, UBS analysts estimate the drug to contribute about 18% to Sun Pharma's FY15 earnings.
The US Food and Drug Administration says out of the 251 drug shortages in 2011, 183 or 72% were those of sterile injectable drugs. In 2012, 84 of the 117 reported shortages involved injectables. As of date, according to data hosted on the US FDA website, of the 194 drug shortfalls, 145 are those of injectables about 75%. The regulator said there are fewer firms making older sterile injectable drugs and the problem is exacerbated by the limited number of raw material suppliers for the drugs.
This small number of manufacturers and limited production capacity for older sterile injectables, combined with the long lead times and complexity of the manufacturing process for injectable drugs, results in these drugs being vulnerable to shortage. When one company has a problem or discontinues, it is difficult for the remaining firms to increase production quickly and a shortage occurs, the USFDA said.
The Indian generics injectables market is worth Rs 12,174 crore and is growing at 5.31% annually. There is renewed interest in this market too.
