In the pharmaceutical industry, Ranitidine Hydrochloride 150 mg is a classic $H_2$-receptor antagonist (H2RA) used to reduce the production of stomach acid. As a pharmacist and manufacturer, I view this 150 mg strength as the “standard therapeutic dose” for both acute relief and the prevention of acid-related gastrointestinal disorders.
At your WHO-GMP facility in Mumbai, this SKU has historically been a high-volume product. However, as your partner, I must highlight that its market presence has shifted significantly due to global regulatory scrutiny regarding NDMA (a probable carcinogen) impurities.
Primary Clinical Indications
GERD (Gastroesophageal Reflux Disease): Relief of heartburn and acid indigestion caused by acid backing up into the esophagus.
Peptic Ulcer Disease: Treatment and prevention of duodenal and gastric ulcers.
Zollinger-Ellison Syndrome: Management of rare conditions where the stomach produces excessive amounts of acid.
Erosive Esophagitis: Healing and maintenance of the esophageal lining damaged by acid.
Aspiration Prophylaxis: Often given before surgery to reduce the risk of acid damage to the lungs during anesthesia.
Mechanism: Selective $H_2$ Blockade
Ranitidine works by turning down the “acid pumps” in the stomach lining.
Competitive Inhibition: It selectively and competitively blocks Histamine $H_2$-receptors on the gastric parietal cells.
Acid Reduction: By blocking histamine—one of the three main triggers for acid production—it significantly reduces the volume and concentration of gastric acid secreted.
Duration: A single 150 mg dose typically suppresses acid production for up to 12 hours.
The Pharmacist’s “Technical Warning”
The NDMA Recall Alert: Since late 2019/2020, many global health authorities (including the FDA and EMA) have recalled or restricted Ranitidine due to the presence of NDMA impurities that can increase over time or with heat.
Renal Adjustment: Ranitidine is primarily excreted by the kidneys. In patients with significant renal impairment, the dose must be reduced to avoid accumulation and CNS side effects like confusion.
B12 Deficiency: Long-term use (more than 2 years) can interfere with the absorption of Vitamin $B_{12}$, as stomach acid is required for its release from food.
The Manufacturer’s Perspective: Technical & Export
From a production and B2B standpoint at your facility in Mumbai:
The “Famotidine” Pivot: Due to the Ranitidine recalls, many manufacturers in Mumbai have successfully pivoted to Famotidine 20 mg/40 mg. If you are listing products on your marketplace, I recommend highlighting Famotidine as the safer, more stable $H_2$ blocker for 2026.
Stability for Export: Ranitidine is highly sensitive to heat and moisture, which accelerates NDMA formation. If manufacturing, utilizing Alu-Alu blister packaging and strict temperature-controlled storage (below 25°C) is mandatory.
