🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two bronchodilators with complementary mechanisms. Doxofylline, a methylxanthine, inhibits phosphodiesterase enzymes, increasing cyclic AMP levels, which leads to relaxation of bronchial smooth muscle and mild anti-inflammatory effects. Salbutamol, a selective beta-2 adrenergic agonist, stimulates beta-2 receptors on airway smooth muscle, causing rapid relaxation and bronchodilation. Together, they provide both immediate and sustained relief from bronchospasm.

🤱 Lactation Safety
Salbutamol is excreted in breast milk and may cause tachycardia or tremor in the infant. Doxofylline is also likely to be excreted in breast milk. Consult your doctor before breastfeeding while taking this medicine.
💊 Overdose Management
Overdose may cause severe tachycardia, arrhythmias, hypokalemia, hyperglycemia, and seizures. Seek immediate medical attention. Treatment is supportive and symptomatic, including monitoring of vital signs, electrolytes, and cardiac rhythm. There is no specific antidote. Activated charcoal may be considered if ingestion is recent. Hemodialysis is not effective for salbutamol but may be considered for doxofylline in severe cases.
⏰ Missed Dose
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not double the dose to catch up.
Additional Safety Advice
Take this medicine exactly as prescribed by your doctor. Do not crush, chew, or break the tablet; swallow it whole with water. Avoid alcohol and caffeine-containing products as they may increase side effects. Inform your doctor if you have heart disease, high blood pressure, diabetes, thyroid disorders, or liver/kidney problems. Do not use this medicine for acute asthma attacks; use your rescue inhaler instead. Keep regular follow-up appointments for monitoring of heart rate, blood pressure, and blood potassium levels. Store at room temperature away from moisture and heat. Keep out of reach of children.
👴 Special Considerations for Elderly

🦷 Dental Procedures
Inform your dentist about this medicine before any dental procedure. It may cause dry mouth or interact with local anesthetics containing epinephrine, increasing cardiovascular effects.
