उपयोग: यह दवा ब्रोमहेक्सिन और सालबुटामोल का संयोजन है, जिसका उपयोग बलगम वाली खांसी और घरघराहट के इलाज में किया जाता है। ब्रोमहेक्सिन बलगम को पतला करता है जिससे उसे बाहर निकालना आसान हो जाता है, और सालबुटामोल श्वास नलियों को फैलाकर सांस लेने में राहत देता है। यह दवा ब्रोंकाइटिस और अन्य श्वसन रोगों में उपयोगी है। यह केवल डॉक्टर के पर्चे पर ही लेनी चाहिए।

साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में मतली, सिरदर्द, चक्कर आना, हाथ-पैर कांपना और दिल की धड़कन तेज होना शामिल हैं। ये आमतौर पर हल्के होते हैं और कुछ समय में ठीक हो जाते हैं। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन यदि सांस लेने में कठिनाई, सीने में दर्द, या चेहरे पर सूजन हो तो तुरंत डॉक्टर से मिलें।

सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। अपने आप मात्रा न बढ़ाएं या घटाएं। उपयोग से पहले बोतल को अच्छी तरह हिलाएं और मापने वाले कप से सही मात्रा लें। यदि आपको हृदय रोग, उच्च रक्तचाप, मधुमेह या थायरॉइड की समस्या है तो डॉक्टर को बताएं। धूम्रपान और शराब से बचें। दवा को ठंडी और सूखी जगह पर रखें।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionBromhexine is rapidly absorbed from the gastrointestinal tract after oral administration. Salbutamol is also well absorbed orally, although its systemic bioavailability is reduced by first-pass metabolism in the liver. Specific absorption data for this fixed-dose combination syrup are not established from the available information.
DistributionBromhexine and salbutamol are distributed widely throughout the body. Salbutamol crosses the placenta and is excreted in breast milk. Protein binding data for bromhexine and salbutamol are not established from the available information for this specific product.
Protein BindingNot established from the available information.
MetabolismBromhexine undergoes extensive first-pass metabolism in the liver, primarily by cytochrome P450 enzymes. Salbutamol is metabolized in the liver mainly by sulfation to an inactive sulfate conjugate. Specific metabolic data for this combination syrup are not established from the available information.
Half-LifeThe elimination half-life of bromhexine is approximately 1 hour, while that of salbutamol is about 4 to 6 hours. However, specific half-life data for this fixed-dose combination syrup are not established from the available information.
ExcretionBromhexine and its metabolites are excreted mainly in the urine. Salbutamol is excreted primarily in the urine as unchanged drug and sulfate conjugates. Specific excretion data for this combination syrup are not established from the available information.
BioavailabilityThe oral bioavailability of bromhexine is approximately 75% to 80% due to first-pass metabolism. The oral bioavailability of salbutamol is approximately 50% due to first-pass metabolism. Specific bioavailability data for this fixed-dose combination syrup are not established from the available information.
Onset of ActionSalbutamol begins to act within 5 to 15 minutes after oral administration, but the onset may be slower compared to inhaled forms. Bromhexine's mucolytic effect may take several hours to become noticeable. Specific onset data for this combination syrup are not established from the available information.
Peak Plasma TimePeak plasma concentrations of bromhexine are reached about 1 hour after oral administration. For salbutamol, peak plasma levels occur within 2 to 4 hours after oral intake. Specific peak plasma time for this combination syrup is not established from the available information.
Duration of ActionThe bronchodilator effect of oral salbutamol lasts for about 4 to 6 hours. The mucolytic effect of bromhexine may last for several hours. Specific duration data for this combination syrup are not established from the available information.

How It Works

This medicine combines two active ingredients with complementary actions. Bromhexine works as a mucolytic agent by breaking down the structure of acidic mucopolysaccharide fibers in mucus, reducing its viscosity and making it easier to expel. It also stimulates the production of serous fluid in the respiratory tract, further thinning secretions. Salbutamol is a selective beta-2 adrenergic receptor agonist that binds to beta-2 receptors on bronchial smooth muscle cells, causing relaxation and widening of the airways. This dual action helps both to clear mucus and to relieve bronchospasm, providing symptomatic relief in conditions where both problems coexist.

Mechanism Steps

1
Bromhexine breaks down mucus structure: Bromhexine disrupts the acidic mucopolysaccharide fibers in mucus, reducing its thickness and making it easier to cough out.
2
Bromhexine increases serous secretion: It stimulates the respiratory tract to produce more watery fluid, further diluting thick mucus.
3
Salbutamol binds to beta-2 receptors: Salbutamol attaches to beta-2 adrenergic receptors on the smooth muscle cells lining the airways.
4
Bronchial smooth muscle relaxation: This binding triggers a cascade that relaxes the muscles, widening the airways and improving airflow.
5
Combined effect: The two actions together ease breathing and help clear mucus, providing relief from cough and wheezing.
