kertannaisannos

Kertannaisannos is a term used in pharmacology and medicine to describe a dose administered after the initial dose within a treatment regimen. The term is primarily encountered in Finnish medical texts and clinical guidelines, where it is used to distinguish the second or subsequent administration from the loading or initial dose.

Etymology: The word derives from Finnish kerta, meaning "occasion" or "time," and annos, meaning "dose."

Usage: In practice, the kertannaisannos is chosen to help maintain therapeutic drug concentrations between doses. Its specific amount and timing depend on the drug's pharmacokinetics, including half-life, clearance, and desired target levels. In some regimens it is equivalent to a maintenance dose; in others it is defined separately by protocol or by clinical guidelines.

Terminology and standardization: Because the term is not widely used in English-language literature, its definition can vary, and some sources treat kertannaisannos as synonymous with "repeat dose" or "subsequent dose" while others reserve it for non-loading doses prescribed after an initial loading dose. Users should rely on the exact protocol or guideline in use.

See also and closing: Related concepts include loading dose, maintenance dose, and dosing interval. Overall, kertannaisannos refers to a second or later dose in a regimen, defined by context and pharmacokinetic considerations.
