Understanding Bupivacaine Hydrochloride and Its API Requirements

Bupivacaine Hydrochloride is chemically known as 1-Butyl-N-(2,6-dimethylphenyl)piperidine-2-carboxamide hydrochloride. As an active pharmaceutical ingredient, it must adhere to stringent Good Manufacturing Practice (GMP) standards, especially considering its injectable usage. The preservative-free aspect complicates procurement, as APIs designated for such formulations must be free from residual contaminants, cross-contamination, and excipients.

Manufacturers sourcing Bupivacaine Hydrochloride API focus on suppliers complying with major pharmacopeias, such as the United States Pharmacopeia (USP), European Pharmacopoeia (EP), and Japanese Pharmacopoeia (JP). Adequate analytical testing, stability data, and consistency across batches are critical factors in supplier selection.
