Rani-Q | Ranitidine uses, dose and side effects


150 mg tablets

What Rani-Q is and what it is used for

Rani-Q provides relief of symptoms in case of temporary heartburn and acid regurgitation.

Ranitidine is histamine (H2-) receptor blocker and works by reducing the production of hydrochloric acid in the stomach. Normally, gastric juice is very acidic and can cause heartburn and acid reflux when leaking up to the esophagus. One tablet can give you symptom relief and the antacid effect lasts up to 12 hours.

Acid production can be stimulated by smoking, alcohol, spicy foods, and stress. Some medicines such as acetylsalicylic acid and other anti-inflammatory drugs for joint and muscle problems can also be the cause of heartburn and other stomach acid-related problems. Contact your pharmacy for information.

Heartburn and acid reflux can be caused by the upper stomach mouth sagging and gastric juice penetrating the esophagus at bedtime or heavy lifting. Smoking, coffee, alcohol, and certain medications can contribute to the relaxation of the upper stomach and mouth. Heartburn and acid reflux can also occur with stomach ulcers and in rare cases even in more serious diseases of the stomach or esophagus. An important measure that can provide relief in heartburn and acid reflux is to change their lifestyle. This can include reducing smoking, avoiding coffee, alcohol, spicy foods, late evening meals, and heavy lifting. You should try to get a regular and stress-free lifestyle. Raising the head end during the night can also relieve the discomfort. Another measure may be treated with over-the-counter medications that can neutralize hydrochloric acid or inhibit the production of hydrochloric acid. If these measures do not help, consult your doctor. This is especially important if you have persistent or recurrent problems, difficulty swallowing, or if your doctor has told you that you have impaired kidney function.
