Introduction
The global pharmaceutical supply chain is a complex network of manufacturers, raw material providers, and distributors, ensuring the consistent availability of essential drugs. Among widely used medications, ibuprofen and diphenhydramine hydrochloride are critical across therapeutic categories such as analgesics, antipyretics, and antihistamines. Securing reliable suppliers for these compounds involves understanding the landscape of active pharmaceutical ingredient (API) producers, excipient manufacturers, and finished drug producers.
Overview of Ibuprofen and Diphenhydramine Hydrochloride
Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) used to reduce pain, fever, and inflammation. It is manufactured globally, with select companies leading in production capacity. Its chemical name is (RS)-2-(4-(2-methylpropyl)phenyl)propanoic acid.
Diphenhydramine Hydrochloride is an antihistamine primarily used for allergy relief, sleep aid, and motion sickness. Chemically known as N,N-Dimethyl-3-(1-methyl-3-phenylpropyl)amine hydrochloride, it is produced by many pharmaceutical companies with established manufacturing processes.
