🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by selectively stimulating beta-2 adrenergic receptors located on the smooth muscle cells of the airways. When salbutamol binds to these receptors, it activates an enzyme called adenylate cyclase, which increases the levels of cyclic adenosine monophosphate (cAMP) inside the cells. The rise in cAMP causes the smooth muscle to relax, leading to widening of the airways (bronchodilation). This effect occurs rapidly and helps to relieve wheezing and shortness of breath. At usual inhaled doses, salbutamol has relatively little effect on beta-1 receptors in the heart, but higher doses can stimulate the heart and cause a faster heart rate.
Mechanism Steps
💡 How to Take brethnol syrup
Strength: Metered-dose inhaler delivering 100 micrograms of salbutamol per actuation.
Dosage Information
| Adult Dosage | The usual adult dose for acute relief of bronchospasm is one to two inhalations (100 to 200 micrograms) as needed, up to a maximum of 4 to 8 inhalations in 24 hours. For prevention of exercise-induced bronchospasm, two inhalations (200 micrograms) are taken 15 to 30 minutes before exercise. The dose must be individualized by a qualified clinician based on the indication, age, weight, renal and hepatic function, and response to treatment. Do not exceed the prescribed dose. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children. |
| Elderly Dosage | Elderly patients may be more sensitive to the cardiac effects of salbutamol. Use with caution and monitor heart rate and blood pressure. The dose should be individualized by a qualified clinician. |
| Renal Impairment | No specific dose adjustment is typically required for mild to moderate renal impairment. In severe renal impairment, use with caution and monitor for adverse effects. Consult a clinician for individualized dosing. |
| Hepatic Impairment | No specific dose adjustment is typically required for mild to moderate hepatic impairment. In severe hepatic impairment, use with caution. Consult a clinician for individualized dosing. |
| Maximum Daily Dose | The maximum recommended daily dose is generally 8 inhalations (800 micrograms) in 24 hours. However, this may vary based on medical advice. Do not exceed the dose prescribed by your doctor. |
