🇮🇳 aus-q tablet के बारे में (Hindi Summary)

उपयोग: यह दवा ब्रोमहेक्सिन और क्लोरफेनिरामाइन मेलिएट का संयोजन है। यह बलगम को पतला करके खांसी को आसान बनाती है और एलर्जी के लक्षणों जैसे नाक बहना, छींक आना और आंखों में पानी आना को कम करती है। यह आमतौर पर गले की खांसी, जुकाम और एलर्जी राइनाइटिस के इलाज के लिए इस्तेमाल की जाती है। इस दवा से नींद आ सकती है, इसलिए गाड़ी चलाने से बचें। डॉक्टर के निर्देशानुसार ही लें।

साइड इफेक्ट्स: आम दुष्प्रभावों में नींद आना, मुंह सूखना, चक्कर आना, जी मिचलाना और पेट में हल्की परेशानी शामिल हैं। कभी-कभी सिरदर्द, धुंधली दृष्टि और कब्ज हो सकती है। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन एलर्जी, रक्त विकार या लीवर की समस्या हो सकती है। अगर कोई गंभीर लक्षण दिखे तो तुरंत डॉक्टर से मिलें।

सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। खुराक से अधिक न लें। जब तक पता न चले कि यह दवा आप पर कैसा असर करती है, तब तक गाड़ी न चलाएं और मशीन न चलाएं। शराब न पिएं क्योंकि इससे नींद और चक्कर बढ़ सकते हैं। अगर आपको ग्लूकोमा, प्रोस्टेट की समस्या, मूत्र रोक, लीवर या किडनी की बीमारी है तो डॉक्टर को बताएं। बच्चों से दूर रखें। गर्भावस्था या स्तनपान के दौरान डॉक्टर से सलाह लें।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionBromhexine is rapidly absorbed from the gastrointestinal tract after oral administration. Chlorpheniramine maleate is also well absorbed orally. Food may slightly delay absorption but does not significantly reduce the extent of absorption.
DistributionBromhexine is widely distributed to body tissues, including the lungs. Chlorpheniramine maleate is widely distributed and crosses the blood-brain barrier, which explains its sedative effects.
Protein BindingBromhexine is approximately 95% bound to plasma proteins. Chlorpheniramine maleate is about 70% bound to plasma proteins.
MetabolismBromhexine undergoes extensive first-pass metabolism in the liver, primarily by cytochrome P450 enzymes, to active and inactive metabolites. Chlorpheniramine maleate is metabolized in the liver, mainly by CYP2D6, to inactive metabolites.
Half-LifeThe elimination half-life of bromhexine is approximately 1 to 2 hours. Chlorpheniramine maleate has a longer half-life of about 12 to 43 hours, which can be prolonged in elderly patients and those with liver disease.
ExcretionBromhexine metabolites are excreted mainly in the urine. Chlorpheniramine maleate and its metabolites are excreted primarily in the urine.
BioavailabilityBromhexine has a low oral bioavailability of about 20% due to first-pass metabolism. Chlorpheniramine maleate has an oral bioavailability of approximately 25% to 50%.
Onset of ActionBromhexine's mucolytic effect begins within 30 to 60 minutes after oral administration. Chlorpheniramine's antihistamine effect starts within 30 to 60 minutes.
Peak Plasma TimeBromhexine reaches peak plasma concentration about 1 hour after oral administration. Chlorpheniramine maleate reaches peak plasma concentration about 2 to 3 hours after oral administration.
Duration of ActionBromhexine's effect lasts about 4 to 6 hours. Chlorpheniramine's antihistamine effect lasts about 4 to 6 hours, but sedation may persist longer.

How It Works

This medicine combines two active ingredients with complementary actions. Bromhexine is a mucolytic agent that reduces the viscosity of bronchial secretions by breaking down acidic mucopolysaccharide fibers and stimulating serous secretion, which helps thin mucus and aids expectoration. Chlorpheniramine maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors, reducing allergy symptoms such as sneezing, rhinorrhea, and lacrimation. It also has anticholinergic properties that contribute to drying of respiratory secretions.

Mechanism Steps

1
Bromhexine thins mucus: Bromhexine breaks down acidic mucopolysaccharide fibers in bronchial secretions and stimulates serous secretion, reducing mucus thickness and making it easier to cough out.
2
Chlorpheniramine blocks histamine: Chlorpheniramine maleate competitively binds to histamine H1 receptors on cells in the nose, eyes, and airways, preventing histamine from triggering allergy symptoms.
3
Anticholinergic drying effect: Chlorpheniramine also blocks acetylcholine receptors, which reduces runny nose and watery eyes but can cause dry mouth and urinary hesitancy.
4
Sedation: Chlorpheniramine crosses the blood-brain barrier and causes drowsiness by blocking histamine in the central nervous system.
