Ventolin contains salbutamol, a short-acting beta-2 agonist (SABA). This means it quickly relaxes the muscles around your airways, making it easier to breathe.
Salbutamol works by binding to specific receptors in your lungs. This binding triggers a cascade of events leading to airway dilation. The effect is typically noticeable within minutes and lasts for several hours.
It’s crucial to understand that salbutamol is a rescue medication, used to treat symptoms as they arise. It’s not a preventative medication like inhaled corticosteroids.
| Mechanism of Action | Bronchodilation via beta-2 receptor agonism |
| Onset of Action | Rapid, within minutes |

Always follow your doctor’s prescription and instructions carefully. If you have questions about Ventolin or salbutamol, consult your physician or pharmacist. They can provide personalized advice based on your specific needs and medical history. Misuse can lead to adverse effects. Proper use ensures optimal symptom relief.
