However, data from a clinical drug-drug interaction study involving montelukast and rosiglitazone a probe substrate representative of drugs primarily metabolized by CYP2C8 in 12 healthy individuals demonstrated that 4mg pharmacokinetics of rosiglitazone are not altered when the drugs are coadministered, indicating that montelukast does not inhibit CYP2C8 in vivo.
Therefore, montelukast is not anticipated singulair alter the metabolism of tablets metabolized by this enzyme e. Pharmacodynamics Montelukast causes inhibition of airway cysteinyl leukotriene receptors as demonstrated by the ability to inhibit bronchoconstriction due to inhaled LTD4 in chews.
Doses as low as 5 mg cause substantial blockage of LTD4-induced bronchoconstriction.
The pharmacokinetics of montelukast are similar whether dosed in the morning or evening. Efficacy has been demonstrated for asthma when montelukast was administered in the evening without regard to time of food ingestion.
Efficacy was demonstrated for seasonal allergic rhinitis when montelukast was administered in the morning or the evening without regard to time of food ingestion.

In allergic rhinitisSingulair are released from the nasal mucosa after allergen exposure during both earlyand late-phase reactions and are associated with symptoms of allergic rhinitis.
Pharmacodynamics Montelukast chews inhibition of airway cysteinyl leukotriene receptors as demonstrated by the ability to inhibit bronchoconstriction due to inhaled LTD4 in asthmatics.
Doses as low as 5 mg cause substantial blockage of LTD4-induced bronchoconstriction. The relationship between these observations and the clinical benefits of montelukast noted in the clinical trials is not known [see Clinical Studies].
Pharmacokinetics Absorption Montelukast is rapidly absorbed following oral administration, singulair tablets 4mg chew. After administration of the mg filmcoated tablet to fasted adults, the mean peak montelukast plasma concentration Cmax is achieved in 3 to 4 hours Tmax.
