biological halflife

Biological half-life is the time it takes for the body to reduce the amount of a substance, such as a drug or toxin, by half through natural processes like metabolism and excretion. It's a measure of how quickly the body detoxifies or eliminates a substance. For example, if a drug has a biological half-life of 4 hours, after 4 hours, only half of the original amount remains in the body. Understanding this helps determine dosing schedules and how long a substance stays in the system. It varies depending on the substance and individual factors like age, liver function, and overall health.
