I think the golden period for the pharma business has just now started with the most of the block buster drugs going off patent in FY16 to FY20. So there huge opportunity for all the companies to get a pie of it.
More MNC companies need minimum 4 -5 blockbuster drugs to maintain there current growth rates which is very difficult. So we will see more companies will consolidate for more takeovers in the future because they cannot match the skills and cost of Indian pharma business.
So I think we can still get 20 - 25% growth in the pharma business for atleast another minimum 5 years.
It's a win win situation for the foreign countries where they free healthcare services, they want cheaper drugs for healthcare.
