साइड इफेक्ट्स: इस दवा के आम दुष्प्रभावों में सिरदर्द, चक्कर आना, कब्ज, दस्त और थकान शामिल हैं। ये आमतौर पर हल्के होते हैं और कुछ समय में ठीक हो जाते हैं। कभी-कभी मतली, उल्टी, पेट में असहजता, मुंह सूखना और भूख न लगना जैसी समस्याएं हो सकती हैं। दुर्लभ मामलों में भ्रम, मतिभ्रम, या गंभीर एलर्जी प्रतिक्रिया हो सकती है। अगर कोई भी दुष्प्रभाव लंबे समय तक बना रहे या गंभीर हो, तो तुरंत डॉक्टर से संपर्क करें।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionFamotidine is absorbed from the gastrointestinal tract after oral administration. The bioavailability is approximately 40% to 45%. Food does not significantly affect the extent of absorption, but it may slightly delay the time to peak concentration.
DistributionFamotidine is distributed widely in body tissues. It crosses the placenta and is excreted in breast milk. The volume of distribution is approximately 1.1 to 1.4 L/kg.
Protein BindingFamotidine is approximately 15% to 20% bound to plasma proteins.
MetabolismFamotidine undergoes minimal hepatic metabolism. It is primarily eliminated unchanged in the urine.
Half-LifeThe elimination half-life of famotidine is approximately 2.5 to 3.5 hours in patients with normal renal function. In patients with severe renal impairment, the half-life may be prolonged to 20 hours or more.
ExcretionFamotidine is excreted primarily unchanged in the urine. Approximately 65% to 70% of an oral dose is recovered in the urine as unchanged drug. Renal clearance is approximately 250 to 450 mL/min.
BioavailabilityThe oral bioavailability of famotidine is approximately 40% to 45%.
Onset of ActionThe onset of acid suppression occurs within 1 hour after oral administration.
Peak Plasma TimePeak plasma concentrations are reached approximately 1 to 3 hours after oral administration.
Duration of ActionThe duration of acid suppression is approximately 10 to 12 hours.

How It Works

This medicine is a competitive inhibitor of histamine at the H2 receptors located on the basolateral membrane of gastric parietal cells. By blocking these receptors, it reduces the intracellular cyclic AMP levels, which in turn decreases the activity of the proton pump and reduces gastric acid secretion. It inhibits both basal and stimulated acid secretion, including that stimulated by food, histamine, and pentagastrin. This medicine has a longer duration of action than cimetidine and does not have anti-androgenic effects or significantly inhibit cytochrome P450 enzymes.

Mechanism Steps

1
Binding to H2 receptors: This medicine binds competitively to histamine H2 receptors on the parietal cells of the stomach.
2
Reduction of cyclic AMP: Blocking H2 receptors decreases intracellular cyclic AMP levels in parietal cells.
3
Inhibition of proton pump: Lower cyclic AMP reduces the activity of the proton pump (H+/K+ ATPase), leading to decreased acid secretion.
4
Decreased gastric acid output: The overall result is a reduction in both basal and stimulated gastric acid secretion.

💡 How to Take acidosh 40mg capsule

Strength: Famotidine 40 mg immediate-release tablet

1Take this medicine exactly as prescribed by your doctor.
2Swallow the tablet whole with a glass of water.
3Do not crush, chew, or break the tablet.
4You may take it with or without food.
5Take it at the same time each day to maintain steady levels.
6If you miss a dose, follow the missed dose instructions.
7Do not take more than the prescribed dose.

Dosage Information

Adult DosageThe usual adult dose for active duodenal ulcer is 40 mg once daily at bedtime for 4 to 8 weeks. For active benign gastric ulcer, the dose is 40 mg once daily at bedtime for 4 to 8 weeks. For gastroesophageal reflux disease, the dose is 20 mg twice daily for up to 12 weeks. For pathological hypersecretory conditions, the dose is individualized, starting at 20 mg every 6 hours and titrated based on acid output. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may have reduced renal function, which can prolong the elimination half-life of famotidine. Dose adjustment may be necessary based on renal function. Use with caution and monitor for central nervous system side effects.
Renal ImpairmentIn patients with moderate renal impairment (creatinine clearance less than 50 mL/min), the dose should be reduced to 20 mg once daily or 40 mg every other day. In severe renal impairment (creatinine clearance less than 10 mL/min), the dose should be further reduced to 20 mg every other day or as directed by a physician.
Hepatic ImpairmentNo specific dosage adjustment is required for hepatic impairment, as famotidine is minimally metabolized by the liver. However, monitor liver function tests periodically.
Maximum Daily DoseThe maximum recommended daily dose is 40 mg for most indications, but in pathological hypersecretory conditions, doses up to 160 mg per day have been used under close medical supervision.
