ACILOC 150MG

# RANITIDINE 150 MG ## SHORT DESCRIPTION **Ranitidine 150 mg** is an **H2-receptor antagonist (H2 blocker)** that reduces the amount of acid produced by the stomach. It has historically been used for **heartburn, acid reflux/GERD, peptic ulcers, and other acid-related conditions**. > **Important:** Ranitidine has had significant regulatory restrictions because of concerns about **N-nitrosodimethylamine (NDMA)** contamination and formation during storage. The regulatory status differs by country and product. Use only a **currently authorized formulation** supplied through a legitimate pharmacy and follow its current product information. --- ## KEY BENEFITS * Reduces **stomach acid production** * Helps relieve **heartburn** * Helps control symptoms of **acid reflux/GERD** * Historically used to support healing of **gastric and duodenal ulcers** * May relieve acid-related upper-abdominal discomfort * Can be used for certain conditions associated with excessive stomach acid > Ranitidine provides acid reduction; it does not treat every cause of abdominal pain or indigestion. --- ## USES / INDICATIONS Ranitidine has historically been used for: ### 1. Gastroesophageal Reflux Disease (GERD) May help relieve: * Heartburn * Acid regurgitation * Acid-related discomfort ### 2. Peptic Ulcers Historically used in the treatment of: * Gastric ulcers * Duodenal ulcers ### 3. Heartburn and Acid Indigestion May reduce symptoms caused by excess gastric acid. ### 4. Hypersecretory Conditions Historically used for conditions involving excessive acid secretion, including **Zollinger-Ellison syndrome**. > Approved indications depend on the specific currently marketed formulation and local regulatory requirements. --- ## HOW IT WORKS Ranitidine is an **H2-receptor antagonist**. Histamine normally binds to H2 receptors on stomach parietal cells and stimulates gastric acid secretion. Ranitidine blocks these receptors, thereby reducing acid production. **Ranitidine → blocks H2 receptors → decreases gastric acid secretion → reduces acid-related symptoms.** Reduced acid exposure can also support healing of acid-related ulcers. --- ## DOSAGE & ADMINISTRATION > **Follow the dosage on the current approved product label or the instructions provided by your doctor/pharmacist.** Historically, **150 mg twice daily** was a commonly used adult regimen for several acid-related conditions. However, dosing varies according to the condition, formulation, kidney function, and applicable product labeling. ### General Administration * Take exactly as directed. * Tablets may generally be taken with or without food. * Swallow with water. * Do not exceed the recommended dose. * Do not use an old or recalled ranitidine product. ### Kidney Disease Ranitidine is substantially eliminated through the kidneys. Patients with impaired kidney function may require **dose adjustment**. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next dose. **Do not double the next dose.** --- ## SIDE EFFECTS ### Common Side Effects Possible side effects include: * Headache * Dizziness * Nausea * Vomiting * Constipation * Diarrhea * Abdominal discomfort ### Less Common Effects Some patients may experience: * Fatigue * Skin rash * Confusion, particularly in older adults or people with kidney impairment ### Serious Side Effects Seek immediate medical attention for: * Difficulty breathing * Swelling of the face, lips, tongue, or throat * Severe allergic reaction * Severe confusion * Yellowing of the skin or eyes * Dark urine * Severe or unusual skin reactions --- ## PRECAUTIONS & WARNINGS ### NDMA Safety Concern Ranitidine products have historically been associated with concerns regarding **NDMA**, a probable human carcinogen. Some older ranitidine products were withdrawn or suspended because NDMA levels could increase under certain storage conditions. **Do not use old, recalled, or unapproved ranitidine products.** ### Kidney Disease Tell your doctor if you have kidney disease because ranitidine may accumulate when kidney function is reduced. ### Liver Disease Inform your healthcare professional if you have significant liver disease. ### Persistent Heartburn Do not repeatedly self-treat persistent heartburn without medical evaluation. Long-lasting symptoms may require investigation for GERD or other gastrointestinal conditions. ### Seek Medical Attention for Warning Symptoms Consult a healthcare professional promptly if you have: * Difficulty or pain swallowing * Vomiting blood * Black or tarry stools * Unexplained weight loss * Persistent vomiting * Severe or persistent abdominal pain * Severe chest pain ### Pregnancy Consult your doctor before using ranitidine during pregnancy. ### Breastfeeding Consult a healthcare professional before using ranitidine while breastfeeding. --- ## DRUG INTERACTIONS Ranitidine may interact with certain medicines or affect the absorption of medicines that require stomach acid. ### Antacids Antacids may sometimes be used alongside acid-reducing medicines, but appropriate timing may be recommended depending on the specific products. ### Warfarin Ranitidine may affect **warfarin** therapy in some patients. Appropriate monitoring may be required. ### Procainamide Ranitidine may increase blood concentrations of **procainamide** in some patients. ### Medicines Requiring Stomach Acid for Absorption Because ranitidine reduces gastric acidity, it may affect the absorption of certain medicines. ### Other Medicines Tell your doctor or pharmacist about all: * Prescription medicines * OTC medicines * Vitamins * Herbal products * Dietary supplements before starting treatment. --- ## STORAGE INFORMATION Storage requirements depend on the **specific formulation and manufacturer**. * Follow the storage instructions printed on the current product packaging. * Keep the medicine in its original container. * Protect from excessive heat and moisture. * Keep away from direct sunlight. * Keep out of reach of children. * Do not use after the expiry date. * Do not use products with damaged or suspicious packaging. * Do not use recalled or previously withdrawn ranitidine products. **For any currently authorized formulation, follow its specific storage and post-opening instructions rather than relying on storage information for older ranitidine products.** --- ## PRESCRIPTION STATUS **Ranitidine 150 mg prescription status varies by country and formulation.** Historically, ranitidine was available both as a prescription and over-the-counter medicine in some markets. Because of the NDMA-related regulatory history, availability and legal status should be verified for the **specific product and country**. --- ## GENUINE MEDICINE ASSURANCE When purchasing Ranitidine 150 mg: * Buy only from a **licensed pharmacy or authorized medicine supplier**. * Verify the manufacturer and product registration details. * Check the strength and formulation. * Check the batch/lot number and expiry date. * Ensure the seal and packaging are intact. * Confirm that the product is **currently authorized for sale in your country**. * Do not purchase old, recalled, or suspicious ranitidine products. * Do not assume an older product is equivalent to a currently authorized formulation. * If authenticity is uncertain, consult a pharmacist or the relevant medicines regulatory authority. --- # FAQ – Ranitidine 150 mg ### 1.
