Elderly: Use standard dose, monitor for side effects.
Timing: Inhaler as needed; nebulizer/tablets on schedule.
Notes: Use spacer with inhaler; rinse mouth after use to prevent irritation.

Mechanism of Action

Albuterol stimulates beta-2 adrenergic receptors, relaxing bronchial smooth muscles to open airways and improve airflow.

Composition

Active Ingredient: Albuterol sulfate, drives bronchodilation.
Inactive Ingredients: Inhaler: propellants; Tablets: lactose, magnesium stearate; Nebulizer: saline solution.

Side Effects

Common: Nervousness, tremors, headache, dry mouth, taste changes.
Rare: Throat irritation, muscle cramps.
Serious: Rapid heart rate, chest pain require urgent care.

Contraindications

Avoid in hypersensitivity to albuterol or severe cardiovascular conditions without medical supervision.

Warnings and Precautions

Monitor for cardiovascular effects or overuse symptoms. Caution in patients with heart disease, hypertension, or diabetes.

Drug Interactions

Beta-blockers reduce efficacy; diuretics increase hypokalemia risk. Disclose all medications to provider.

Overdose

Symptoms: palpitations, tremors, chest pain. Seek emergency care immediately.

Pharmacokinetics

Absorption: Rapid via inhalation, peak 5–15 minutes.
Distribution: Local lung action, minimal systemic.
Metabolism: Liver to inactive metabolites.

Storage

Store at 20°C–25°C (68°F–77°F), avoid extreme heat, keep inhalers dry. Dispose expired properly.

Clinical Evidence

Trials confirm Ventolin’s rapid and effective relief of bronchospasm, outperforming placebo and comparable bronchodilators in asthma and COPD management.

Conclusion

Ventolin is a reliable bronchodilator for asthma and COPD, offering rapid relief and versatile forms. Adhere to prescribed regimens, carry inhalers, and consult providers for optimal outcomes.
