Half-life

Half-life refers to the time it takes for half of a substance to decay. In pharmaceuticals, the half-life of a drug indicates how long it takes for half of the active ingredient to be metabolized or eliminated from the body. This helps determine dosing schedules and the duration of a drug’s effects.


Half-life Calculation Formula

The half-life of a substance can be calculated using the following formula:

t(1/2) = 0.693/𝑘

Where, 𝑘 is the decay constant, which represents the rate at which the substance decays.
