How Salbutamol Tablet Works

Salbutamol is a medication that has a significant impact on managing respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). This bronchodilator works by relaxing the smooth muscles in the airways, making breathing easier for those with respiratory issues.

The mechanism of action of salbutamol involves stimulating beta-2 adrenergic receptors in the bronchial muscles. These receptors are present in large numbers throughout the respiratory tract. When salbutamol medicine binds to these receptors, it causes a cascade of intracellular events that ultimately result in bronchodilation.

Can I Take Salbutamol with Other Medicines?

Salbutamol, while effective in managing respiratory conditions, can interact with various medications. It's crucial to inform doctors about all ongoing medicines, including prescription drugs, over-the-counter products, vitamins, and herbal supplements.

The following are some key drug interactions:

• Antidepressants: Certain medications for depression, including moclobemide, phenelzine, amitriptyline, and imipramine, can potentially interact with salbutamol.
• Blood Pressure Medications: Drugs like atenolol or propranolol may interact with salbutamol.
• Corticosteroids: Medications like beclometasone dipropionate (used for asthma) may interact with salbutamol.
• Diuretics: Water tablets such as furosemide can interact with salbutamol.
• General Anaesthetics: Some anaesthetics may interact with salbutamol, potentially causing heart problems and decreased blood pressure.
• Heart Rhythm Medications: Digoxin and other medicines that control irregular heartbeats or fast pulse rates can interact with salbutamol.
• Other Asthma Medications: Xanthine derivatives like theophylline and aminophylline may interact with salbutamol.
