Long March

Sichuan Long March Pharmaceutical is a China-based pharmaceutical manufacturer focused on commercial production of antibiotic active pharmaceutical ingredients and related pharmaceutical products. Founded in 1968 in Leshan, Sichuan, the company appears to be a long-established, state-owned or state-controlled enterprise and a core pharmaceutical unit within Sichuan Lanyan Investment Group. Its business centers on fermentation- and synthesis-based anti-infective manufacturing, with products such as rifampicin, streptomycin, neomycin, gentamicin, oxytetracycline, ivermectin, and related APIs listed by industry sources. The company is positioned primarily as a commercial supplier and manufacturer rather than a clinical-stage biotech developer, with regulatory filings and export activity supporting its role in global API supply. It also appears to maintain animal health and bio-pesticide related operations and has historically referenced multiple subsidiaries and an antibiotics institute.
