🇮🇳 uzal lb 500mg tablet के बारे में (Hindi Summary)

उपयोग: यह दवा एज़िथ्रोमाइसिन 500 मिलीग्राम और लैक्टिक एसिड बैसिलस 60 मिलियन स्पोर्स का संयोजन है। यह बैक्टीरियल संक्रमण जैसे निमोनिया, साइनसाइटिस, गले में संक्रमण, त्वचा संक्रमण और क्लैमाइडिया के इलाज के लिए इस्तेमाल की जाती है। इसमें मौजूद प्रोबायोटिक आंतों के अच्छे बैक्टीरिया को बनाए रखने में मदद करता है और एंटीबायोटिक से होने वाले दस्त को कम कर सकता है। यह दवा डॉक्टर के पर्चे के बिना नहीं लेनी चाहिए।

साइड इफेक्ट्स: आम दुष्प्रभावों में दस्त, जी मिचलाना, पेट दर्द, सिरदर्द और स्वाद में बदलाव शामिल हैं। ये आमतौर पर हल्के होते हैं और दवा बंद करने पर ठीक हो जाते हैं। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन अगर चेहरे या गले में सूजन, सांस लेने में कठिनाई, पीलिया, या खूनी दस्त हो तो तुरंत डॉक्टर से मिलें।

सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। टैबलेट को पानी के साथ पूरा निगलें, चबाएं नहीं। खाने के साथ या बिना खाने के ले सकते हैं, लेकिन पेट खराब हो तो हल्के भोजन के साथ लें। शराब न लें। गर्भवती या स्तनपान कराने वाली महिलाएं डॉक्टर से सलाह लें। कोर्स पूरा करें, बीच में न छोड़ें।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAzithromycin is rapidly absorbed from the gastrointestinal tract after oral administration. The presence of food may slightly alter the rate but not the extent of absorption. The probiotic spores are resistant to gastric acid and reach the intestines where they germinate.
DistributionAzithromycin distributes widely into body tissues and fluids, with high concentrations in phagocytes, which transport it to sites of infection. It achieves higher tissue levels than plasma levels. Protein binding is low and concentration-dependent.
Protein BindingAzithromycin is approximately 7–50% bound to plasma proteins, depending on concentration.
MetabolismAzithromycin undergoes limited hepatic metabolism, primarily by demethylation and hydroxylation, but the majority of the drug is excreted unchanged.
Half-LifeThe terminal elimination half-life of azithromycin is approximately 68 hours, allowing once-daily dosing and short treatment courses.
ExcretionAzithromycin is excreted mainly in bile as unchanged drug, with a smaller portion excreted in urine. The probiotic component is eliminated naturally through the gastrointestinal tract.
BioavailabilityThe oral bioavailability of azithromycin is approximately 37%.
Onset of ActionClinical improvement in infection symptoms may begin within 24–48 hours after the first dose, but full effect depends on the infection and immune response.
Peak Plasma TimePeak plasma concentrations are reached approximately 2–3 hours after oral administration.
Duration of ActionDue to its long tissue half-life, azithromycin continues to exert antibacterial effects for several days after the last dose, which is why short courses are effective.

How It Works

Azithromycin binds to the 50S ribosomal subunit of susceptible bacteria and inhibits bacterial protein synthesis by blocking the translocation step of peptide chain elongation. This stops bacteria from making essential proteins, which prevents their growth and multiplication. The lactic acid bacillus is a live probiotic that helps restore and maintain beneficial gut flora, which can be disrupted by antibiotic therapy.

Mechanism Steps

1
Entry into bacterial cell: Azithromycin penetrates the bacterial cell wall and reaches the ribosome.
2
Binding to 50S subunit: It binds reversibly to the 23S rRNA of the 50S ribosomal subunit.
3
Inhibition of protein synthesis: This binding blocks the translocation of tRNA and prevents elongation of the peptide chain.
4
Bacterial growth arrest: Without essential proteins, bacteria cannot multiply, and the immune system can clear the infection.
5
Probiotic support: Lactic acid bacillus spores help maintain beneficial gut bacteria during and after antibiotic therapy.

Dosage Information

Adult DosageThe usual adult dose of this medicine is one 500 mg tablet taken once daily for 3 to 5 days, depending on the type and severity of infection. For uncomplicated chlamydial urethritis or cervicitis, a single 1 g dose (two 500 mg tablets) may be prescribed. For community-acquired pneumonia, a common regimen is 500 mg once daily for at least 3 days. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Always follow your doctor's prescription exactly.
Pediatric DosagePediatric dosing is not established from available information for this specific 500 mg tablet formulation. Azithromycin is available in pediatric-friendly formulations, and dosing is based on body weight. Consult a pediatrician for appropriate dosing.
Elderly DosageElderly patients may be more susceptible to QT prolongation and cardiac arrhythmias. No specific dose adjustment is required based on age alone, but caution is advised, and renal and hepatic function should be considered. Dose must be individualized by a qualified clinician.
Renal ImpairmentNo dose adjustment is generally needed for mild to moderate renal impairment. In severe renal impairment (eGFR <10 mL/min), azithromycin should be used with caution; however, specific dose adjustments are not well established. Consult a nephrologist or clinical pharmacist.
Hepatic ImpairmentNo specific dose adjustment is established for mild to moderate hepatic impairment. Azithromycin is contraindicated in patients with a history of cholestatic jaundice or hepatic dysfunction associated with prior azithromycin use. Use with caution in severe liver disease.
Maximum Daily DoseThe maximum recommended daily dose is 500 mg for most indications, except for a single 1 g dose for chlamydial infection. Do not exceed the prescribed dose.
