What Is Singulair (Montelukast)?
Singulair is the brand name for Montelukast, an oral medication used to control asthma and allergic conditions.
Montelukast belongs to a class of medicines known as Leukotriene Receptor Antagonists (LTRAs). These medicines help prevent airway inflammation and reduce allergy symptoms.
Generic versions such as Monfast® 4mg contain the same active compound and may be used depending on physician recommendation and availability.
Drug Class and Mechanism of Action
Montelukast is classified as a leukotriene receptor antagonist with anti-inflammatory properties.
How Montelukast Works
It works in several ways:
- Blocks leukotrienes that cause airway inflammation
- Reduces swelling and mucus production
- Prevents narrowing of airways (bronchoconstriction)
- Improves breathing and reduces allergy symptoms
Through these mechanisms, Montelukast helps control asthma and allergic reactions effectively.
How Singulair Works in the Body
Leukotrienes are inflammatory chemicals released during allergic reactions. Singulair blocks their action, helping maintain open airways and better respiratory function.
