Asthalin HFA 100mcg Inhaler is a fast-acting bronchodilator containing Salbutamol (also known as Albuterol), widely used for the relief and prevention of bronchospasm in conditions like asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders. Each puff delivers 100 micrograms of Salbutamol, and the inhaler typically provides 200 metered doses (MDI). It acts quickly to relax the airway muscles, making breathing easier during episodes of wheezing, breathlessness, chest tightness, or coughing.
Salbutamol is a beta-2 adrenergic agonist, which works by stimulating beta-2 receptors in the bronchial muscles, leading to smooth muscle relaxation and bronchodilation. This rapid relief makes Asthalin HFA an essential "rescue" inhaler for managing sudden asthma attacks or respiratory distress. The onset of action is usually within 5 minutes, with effects lasting for about 4 to 6 hours.
The inhaler is portable and easy to use, often prescribed for both adults and children. While highly effective, it should be used only as directed, as overuse can lead to decreased effectiveness and side effects such as tremors, palpitations, nervousness, or throat irritation. For individuals with persistent symptoms, doctors may recommend maintenance medications alongside Asthalin for better long-term control.
