Introduction

BICILLIN C-R 900/300, a widely used long-acting penicillin antibiotic, comprises procaine penicillin G and benzathine penicillin G. Its efficacy in treating various bacterial infections, including syphilis and certain streptococcal infections, depends significantly on the quality and reliable sourcing of its API components. Ensuring an uninterrupted supply of high-quality active pharmaceutical ingredients (APIs) is vital for pharmaceutical manufacturers to meet regulatory standards and maintain product efficacy. This article provides a comprehensive overview of the leading bulk API sources used for BICILLIN C-R 900/300, focusing on global manufacturers, supply chain considerations, and quality assurance protocols.

Composition of BICILLIN C-R 900/300

BICILLIN C-R 900/300 is a combination API formulation consisting of:

Procaine Penicillin G (Procaine Benzylpenicillin): Acts as a local anesthetic and prolongs the antibiotic effect.
Benzathine Penicillin G (Benzathine Benzylpenicillin): Provides a slow-release mechanism, extending the duration of action.

The active ingredients—both penicillin derivatives—are produced via fermentation processes involving specific bacterial strains, primarily Penicillium species, or through chemical modifications of penicillin bases.
