Salbutamol (Albuterol)

Salbutamol is a short-acting beta2-adrenergic agonist (SABA) that acts by relaxing airway smooth muscle, leading to rapid bronchodilation. It is primarily used as a rescue medication to quickly relieve symptoms of acute asthma, wheezing, and reversible obstructive airway disease.

Dosage by Body Weight

Inhalation is the preferred route of administration for quick-relief therapy. For inhalers: 1 to 2 puffs (90 to 180 mcg) every 4 to 6 hours as needed. For nebulizers: 2.5 mg to 5 mg per dose. For oral syrup (2mg/5mL) in children, dosing is typically based on weight (0.1 mg to 0.2 mg/kg per dose, 3 to 4 times daily). Consult a healthcare provider for precise dosing.

    Tracking Notes
    Strict medical supervision required. Inhalation route via a spacer is highly preferred over oral syrup to minimize systemic side effects.

    3 to 4 times daily
    Tracking Notes
    Do not exceed 8 mg total in a 24-hour period. Shake syrup well before administering.
