1. What is Ranigast and what is it used for

Ranigast is a medication that inhibits the secretion of hydrochloric acid in the stomach.
It is used in patients being treated in a hospital, in whom a reduction in acid secretion is indicated and oral administration is not possible, e.g., in:
duodenal and gastric ulcer disease,
other conditions with symptomatic excessive acid secretion.

2. Important information before using Ranigast

When not to use Ranigast

  • if the patient is hypersensitive to ranitidine or any of the other ingredients of this medication (listed in section 6).

Warnings and precautions

Before starting treatment with Ranigast, discuss with your doctor:

  • if the patient has severe renal impairment, as ranitidine is excreted by the kidneys; in patients with severe renal impairment, smaller doses of the medication are used (as decided by the doctor);
  • if the patient has porphyria (ranitidine may cause acute attacks of the disease);
  • if the patient has diabetes, respiratory diseases, and immune system disorders (there may be an increased risk of developing hospital-acquired pneumonia);
  • if the diagnosis of gastric ulcer is not certain. Before starting treatment, it is necessary to rule out the malignant nature of the ulcer (especially in middle-aged and elderly patients with new dyspeptic disorders, or patients whose symptoms have changed), as ranitidine may mask symptoms accompanying tumors.

Ranigast and other medications

Tell your doctor about all medications you are currently taking or have recently taken, as well as medications you plan to take.
The medications listed below may occur under several different trade names. They will not be included in this section, only the active substances or their groups are listed. Therefore, you should carefully check the packaging and the leaflet of the medication you are taking for the name of its active substance.
Ranigast does not enhance the effects of medications such as:

  • amoxicillin (antibiotic),
  • diazepam (sedative and anxiolytic medication used in the treatment of epilepsy),
  • lidocaine (anesthetic medication also used in the treatment of arrhythmias),
  • phenytoin (antiepileptic medication),
  • metronidazole (antifungal and antiprotozoal medication),
  • propranolol (medication used, among others, in the treatment of hypertension and coronary heart disease),
  • theophylline (medication used in the treatment of asthma).

Ranigast may affect the rate and extent of absorption of medications such as:

  • benzodiazepine medications, such as midazolam, triazolam - used in case of insomnia,
  • glipizide (medication used in the treatment of diabetes),
  • procainamide, N-acetylprocainamide (medications used in arrhythmias).

Ranigast may enhance the effects of anticoagulant medications, such as warfarin, so it is necessary to closely monitor prothrombin time during concomitant treatment with these medications.
Smoking reduces the effectiveness of ranitidine.

Ranigast with food and drink

Food does not affect the intravenously administered Ranigast.

Pregnancy
