What is sub chronic administration?

Subchronic administration refers to the exposure of an organism to a substance, such as a drug or chemical, for a duration that typically ranges from 28 days to several months, but less than a chronic exposure period. This type of administration is often used in toxicology and pharmacology studies to evaluate the effects and safety of substances over a medium-term timeframe. It helps to identify potential adverse effects, pharmacokinetics, and therapeutic efficacy before longer-term studies are conducted.
