Pharmacological Properties:

Clear air? (montelukast soduim) is a selective and orally active leukotriene receptor antagonist that specifically inhibits the cysteinyl leukotrience CysLT1 receptor. Pharmacokinetics Peak plasma concentrations of montelukast are achieved in 2 to 4 hours after oral doses. The mean oral bioavailability is 64% . montelukast is more than 99 % bound to plasma proteins. It is extensively metabolisd in the liver by cytochrome P450 isoenzymes CYP3A4, CYP2A9 , and is excreted principally in the faeces via the bile . Metabolism was reduced and the elimination half-life prolonged in patients with mild to moderate hepatic impairment.
