Executive Summary
Dainippon Sumitomo Pharma (DSP)'s top product Amlodin (amlodipine, licensed from Pfizer) continues to be hit by generic competition, with sales of the calcium antagonist falling by 12% to ¥26.9 billion ($296 million) in the six months to September 30th. The product was opened up to its first generic entrants in Japan last year, and as one of the biggest-selling prescription drugs in the country has seen numerous alternative versions enter the market.
