🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionMontelukast is rapidly absorbed after oral administration. The bioavailability is approximately 64% for the 10 mg tablet and 73% for the 5 mg chewable tablet. Food does not significantly affect absorption.
DistributionMontelukast is highly bound to plasma proteins (more than 99%). It distributes into tissues, but the volume of distribution is not well established.
Protein BindingMore than 99% bound to plasma proteins.
MetabolismMontelukast is extensively metabolized in the liver, primarily by cytochrome P450 enzymes CYP3A4 and CYP2C8.
Half-LifeThe elimination half-life of Montelukast is approximately 2.7 to 5.5 hours in healthy adults.
ExcretionMontelukast and its metabolites are excreted mainly in the bile and feces, with minimal excretion in urine.
BioavailabilityApproximately 64% for the 10 mg tablet and 73% for the 5 mg chewable tablet.
Onset of ActionThe onset of action for Montelukast is within a few hours, but full therapeutic effect may take several days to weeks.
Peak Plasma TimePeak plasma concentration is reached in about 3 to 4 hours for the 10 mg tablet and 2 to 2.5 hours for the 5 mg chewable tablet.
Duration of ActionThe duration of action is approximately 24 hours, allowing for once-daily dosing.

How It Works

This medicine works by selectively blocking the cysteinyl leukotriene receptor type 1 (CysLT1) in the airways and other tissues. Leukotrienes are inflammatory chemicals released by the body during allergic reactions and asthma. By blocking their action, this medicine reduces airway inflammation, mucus production, and bronchoconstriction, leading to improved breathing and reduced allergy symptoms.

Mechanism Steps

1
Leukotriene release: In response to allergens or triggers, the body releases leukotrienes, which are inflammatory mediators.
2
Receptor binding: This medicine binds to the CysLT1 receptor, preventing leukotrienes from attaching to it.
3
Reduced inflammation: Blocking the receptor reduces inflammation, swelling, and mucus production in the airways.
4
Bronchodilation: The airways relax and widen, making breathing easier and reducing asthma symptoms.
