Pharmacokinetics

Absorption: Well absorbed after oral administration.

Distribution: Rapidly and widely distributed; crosses the placenta and enter breast milk.

Metabolism/Excretion: Extensively metabolized by the liver; inactive metabolites excreted by the kidneys. Amount excreted unchanged by the kidneys depends on urine pH; as pH increases, amount excreted unchanged increases from 2–3% up to 80%.

Half-life: 2–3 hr for low doses; up to 15–30 hr with larger doses because of saturation of liver metabolism.
