You should consult your doctor if you experience any of the following:
Usually the preparation is well tolerated. During a long-term usage of high doses there can be possible follow side effects:
nausea, vomiting, heartburn, diarrhea.
hyperexcitability of CNS, headache.
formation of urinary, cystine and oxalate concernments.
Skin and subcutaneous tissue: allergic reactions.
It can cause erythrocyte hemolysis in patients with insufficiency of glucose-6-phosphatdehydrogenase of hematocytes.
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise take it as soon as you remember and then go back to taking it as you would normally.
Ascozin® increases salicylates (increases a risk of crystalluria), ethynilestradiol,
benzylpenicillin and tetracyclines concentrations in blood, and decreases per oral
contraceptives concentration in blood. It reduces anticoagulation effect of coumarin
derivatives. It improves iron drugs absorption in intestine. It increases general
clearance of ethyl alcohol. Quinolone drugs, calcium chloride, salicylate, corticosteroid
decrease vitamin C reserve when used for a long term. Corticosteroids (cortisone
and prednisolone), which are administered in concrete diseases (arthritis, bronchial
astma etc), also reduce vitamin C and zinc levels.
Concurrent usage of ascorbic acid and deferoxamine enhances tissue toxicity of iron, especially in cardiac muscle that can cause decompensation of blood circulatory system. It can be used only in 2 hours after deferoxamine injection. A long-term administration of high doses in patients, who are treated by disulfiram, inhibits disulfamide-alcohol reaction.
High doses of the preparation decrease efficacy of tricyclic depressants.
nausea, vomiting, intestine spasm, diarrhea; it is possible allergic reaction, kidney dysfunction, blood pressure increase, hyperexcitability of CNS, sleep disturbance.
It is symptomatic.

Ranitidine can influence on absorption, metabolism and renal excretion of other medicines.
Ranitidine at therapeutic doses does not change the activity of cytochrome P450 enzyme system and does not potentiate the action of agents, which are metabolized by this system (diazepam, lidocaine, phenytoin, propranolol, theophylline, etc.).
Ranitidine, changing the acidity of stomach, may affect the bioavailability of some medicines. This can result in either an increase of their absorption (triazolam, midazolam, glipizide) or a decrease of their absorption (ketoconazole, atazanavir, delavirdine, gefitinib).
Antacids and sucralfate inhibit Ranitidine absorption, as a result of what the interval between intake of these medicines and ranitidine should be at least 1 – 2 hours. Concurrent use of metoprolol may increase the concentration of metoprolol in serum.
Ranitidine in combination with coumarin anticoagulants (warfarin) may alter the prothrombin time (prothrombin time monitoring is recommended).
High doses of Ranitidine may slow down the excretion of procainamide and N-acetylprokainamid that causes an increase of their level in blood plasma.
There is no data concerning the interaction between Ranitidine and amoxicillin or metronidazole.
Pregnancy and lactation:
The preparation is contraindicated during pregnancy. If the preparation use is necessary during the treatment, then lactation should be stopped.
For children above 12 years old the preparation is used to reduce the duration of the treatment of peptic gastric and duodenal ulcers, for the treatment of gastroesophageal reflux disease, including reflux-esophagitis, and for relief of symptoms of gastroesophageal reflux disease.
In case of allergy to other agents of group of histamine H2-receptors blockers allergic reaction to Ranitidine are possible, therefore, in case of hypersensitivity to other medicines of this group the preparation should be used with caution.
The preparation is used with caution in acute porphyria (including it in anamnesis), immunodeficiency.
Ranitidine is excreted via kidney; therefore, the plasma preparation level in patients with severe kidney insufficiency is increased (see dosage for those patients in "Administration and Dosage" section).
In elderly patients with liver or kidney dysfunction it is possible an impairment of consciousness (mental confusion) that requires a dose lowering.
This preparation treatment may mask the symptoms of gastric carcinoma, therefore, before the treatment it is necessary to exclude presence of malignant neoplasm in stomach.
Patients (especially elderly and with peptic and/or duodenal ulcer in anamnesis) who use Ranitidine concurrently with non-steroid anti-inflammatory drugs should be under a regular observation.
In elderly patients, patients with chronic pulmonary diseases, diabetes mellitus or those with weakened immunity an increased susceptibility to the development of outhospital pneumonia was observed. In simultaneous treatment with theophylline it is necessary to monitor plasma levels of theophylline and adjust the dose.
This preparation treatment is withdrawn gradually due to risk of development of "ricochet" syndrome in case of its abrupt withdrawal.
enhancement of adverse reactions.
symptomatic and supportive therapy.
Ability to influence reaction velocity while driving or operating any other mechanisms.
During the treatment period it is necessary to avoid potentially dangerous activities that require a high concentration of attention and rate of psychomotor reactions.
Individual hypersensitivity to Ranitidine or other preparation's ingredients; presence of malignant diseases of stomach; liver cirrhosis with portal systemic encephalopathy in anamnesis; pregnancy and lactation periods; children age less than 12 years old.
Ranitidine is an antagonist of H2-histamine receptors. Competitively reversibly binding to H2-histamine receptors of parietal cells of mucous coat of stomach, it inhibits basal and stimulated secretion of hydrochloric acid, and eliminates activity of pepsin, promotes pH content of stomach. It decreases the volume of gastric juice caused by baroreceptors irritation (stomach stretch), overeating, action of hormones and biogenic stimulators (gastrin, histamine, pentagastrin, caffeine). Medicine`s action after a single dose lasts 12 hours.
After internal use Ranitidine is absorbed quickly. Its absorption does not depend on food intake. Plasma peak concentration is within the limits of 300 – 500 mcg/ml and is reached in 1 – 3 hours after per oral use of 150 mg of the preparation. Ranitidine bioavailability is 50%. Ranitidine concentration in plasma is proportional to the used dose. Binding to plasma proteins is 15%. It is partly metabolized in liver.
The preparation is excreted mainly via kidneys (60 – 70% of per oral dose) and 26% – with faeces. Half-life period is 2 – 3 hours. Approximately 30% of per oral dose is excreted as unchanged one.
