Introduction to Rantac RD Capsule
Rantac RD Capsule is a combination medication that belongs to the proton pump inhibitors (PPIs) and dopamine antagonists category containing the active ingredient Rabeprazole, Domperidone. This drug treats conditions such as gastroesophageal reflux disease (in which the stomach acid and contents flow back into the esophagus), peptic ulcers (a sore or erosion that forms on the stomach lining), and nausea and vomiting.
This medicine is contraindicated in people with a history of cardiac arrhythmias such as ventricular fibrillation, ventricular tachycardia, or QT prolongation or in those taking medications that prolong the QT interval. Rantac RD Capsule may cause side effects such as dizziness, drowsiness, or vision changes in some individuals. If these effects occur, avoiding activities requiring alertness, such as driving, cycling, or operating machinery, is important until you feel better.
Long-term use of this medicine may result in low magnesium levels in the body (hypomagnesemia). Symptoms of low magnesium levels include fatigue, muscle spasms or weakness, irregular heartbeat, and seizures. If you develop any of these symptoms, notify your doctor immediately. It is necessary to discuss using Rantac RD Capsule with your physician if you are pregnant, suspecting pregnancy, or breastfeeding.

Therapeutic Effects of Rantac RD Capsule
Rabeprazole works by irreversibly binding to the proton pump and inhibiting its function. By doing so, it blocks the final step of acid production. Specifically, this drug inhibits the enzyme's ability to transport hydrogen ions (protons) into the stomach, thereby reducing gastric acid secretion. Domperidone enhances the movement and contractions of the stomach and intestines. It helps to improve gastrointestinal motility and facilitates the food to pass through the digestive part.
Interaction of Rantac RD Capsule with other drugs
Inform your physician about all your medicines, including prescription, over-the-counter, nutritional or vitamin supplements, and herbal products. Certain medications may interact with Rantac RD Capsule and reduce effectiveness by causing undesirable side effects.
