Montelukast, commonly known by its brand name Singulair, is a medication widely used to manage asthma and allergies. It belongs to a class of drugs known as leukotriene receptor antagonists (LTRAs), which work by blocking the action of leukotrienes, substances in the body that cause inflammation, bronchospasm, and mucus production. Montelukast is available in various forms, including tablets, chewable tablets, and oral granules. The focus here will be on the 10mg tablet, often prescribed for adults and adolescents.
Understanding Montelukast Tab 10mg
Montelukast Tab 10mg is indicated for the prophylactic treatment of asthma in adults and children 6 years of age and older. It is also used for the relief of symptoms of seasonal and perennial allergic rhinitis in adults and children 6 years of age and older. This medication is not intended for the immediate relief of acute bronchospasm or status asthmaticus.
How Montelukast Works
Leukotrienes are inflammatory mediators that play a significant role in the pathophysiology of asthma and allergic rhinitis. They are involved in the recruitment of inflammatory cells, increase in vascular permeability, and smooth muscle contraction. Montelukast, by antagonizing the cysteinyl leukotriene receptor, inhibits the action of leukotrienes, thereby reducing inflammation, mucus production, and bronchospasm.
| Mechanism of Action | Description |
|---|---|
| Leukotriene Antagonism | Blocks the action of leukotrienes on their receptors |
| Reduction of Inflammation | Decreases the inflammatory response in the airways |
| Mucus Production | Reduces the production of mucus in the airways |
| Bronchospasm Relief | Relaxes the smooth muscles around the airways, relieving bronchospasm |
