läkemedelsämne

Läkemedelsämne, or drug substance, refers to the active pharmaceutical ingredient (API) within a medicinal product. It is the component responsible for the intended therapeutic effect. In Sweden, the term is used to distinguish the pure chemical entity from the finished drug product, which also includes excipients. These excipients are inactive ingredients that help in the formulation, delivery, and stability of the drug substance.

The identity, purity, and strength of a läkemedelsämne are critical for its safety and efficacy. Regulatory authorities, such as the Swedish Medical Products Agency (Läkemedelsverket), set stringent standards for the manufacturing and quality control of these substances. This includes detailed specifications for raw materials, manufacturing processes, and analytical testing.

The development of a läkemedelsämne involves extensive research and preclinical testing to understand its pharmacological properties, potential side effects, and optimal dosage. Once deemed safe and effective, it undergoes clinical trials before it can be approved for use in human or veterinary medicine. The production of a läkemedelsämne often occurs in specialized facilities adhering to Good Manufacturing Practice (GMP) guidelines to ensure consistent quality and prevent contamination.
