What raw materials are used in the pharmaceutical industry?

The pharmaceutical industry primarily uses active pharmaceutical ingredients (APIs), which are the core components that produce the desired therapeutic effect. These APIs are often derived from natural sources such as plants and microorganisms, as well as synthesized from chemical compounds. Additionally, excipients, which are inactive substances used as carriers for the active ingredients, play a crucial role in formulation. Other raw materials include solvents, stabilizers, and packaging materials that ensure the efficacy and safety of pharmaceutical products.
