The biological steady-state half-life of salbutamol in serum after intravenous infusion is approximately 6 hours.Salbutamol is well absorbed after oral administration and is partially metabolised in the gastrointestinal tract and in the liver. In the plasma, the substance is present as free salbutamol and in metabolite form. Free salbutamol is fully effective, while the metabolite shows hardly any beta-stimulating properties.
