The global antibiotics market is highly competitive and is dominated by the large multinational pharmaceutical companies, along with significant generic manufacturers mainly from India and China. The key strategies include vertical integration of API production, strategic partnerships for R&D in novel antibiotic classes, and portfolio diversification into complex generics to combat thin margins.
