Short-term treatment of active duodenal ulcer. 2. Maintenance therapy for duodenal ulcer patients at reduced dosage alter healing of acute ulcers. 3. The treatment of pathological hypersecretory conditions (e.g., Zolllnger-EUison syndrome and systemic mastocytosB). 4. short-term treatment of active, benign gastric ulcer. 5. Maintenance therapy for gastnc ulcer patients at reduced dosage after healing of acute ulcers. 6. Treatment of gastroesophageal reflux disease (GERD). 7.Treatmemofendoscoplcalfydlagiio^err) erosive esophagltis.

CONTRAINDICATIONS: Zantac- Is contralndicated for patients known to have hypersensl- tivity to the drug or any of the Ingredients (see PRECAUTIONS). PRECAUTIONS: G«*nl: 1. Symptomatic response to Zantac' therapy does not preclude the presence of gastric malgnancy. 2. Since Zintac is excreted primarily by the kidney, dosaoe should be adjusted In patients with Impaired renal function (see DOSAGE AND ADMINISTRATION).

Utwatwy Tests: False-positive tests for urine protein with Multistlx* may occur during Zantac therapy, and therefore testing with sultosalicylic acid is recommended. On) MincUM*: Although Zantac has been reported to bind weakly to cytochrome P- 450 /n MD, recommended doses of the drug do not Inhibit the action of the cytochrome P-450-linked oxygenase enzymes In the liver. However, there have been isolated reports of drug Interactions that suggest that Zantac may affect the bloavaUabHlty of certain drugs by some mechanism as yet unidentified (e.g., a pH-dependent effect on absorption or a change In volume of distribution). Increased or decreased prolhrombln times have been reported during concurrent use of ranltidine and warfarin. However, In human phamucokinetic studies with dosages of ranl- tidine up to 400 mg per day, no Interaction occurred: ranltidine had no effect on warfarin clearance or prothrombln time. The possibility of an interaction with warfarin at dosages of ranltidine higher than 400 mgperday has not been Investigated. CirtiMMMsH, Mutagmnri. Impalmtetrt of FiUHKy. There was no Indication ol tu- mortoenlc or carcinogenic effects In life-span studies in mice and rats at dosages up to 2,000 mg/kg per day.

In a dominant lethal assay, a single oral dose of 1,000 mg/kg to mate rats was without eflect on the outcome of two matlnasper week for the next 9 weeks. performed in rats and rabbits at doses up to 160 times the human dose and have revealed no evidence of impaired fertility or harm to the fetus due to Zantac. There are, however, no adequate and well-controlled studies In pregnant women. Because animal reproduction studies an not always predictive ol human response, this drug should be used during pregnancy only If dearly needed. NiinlM Milton: Zantac Is secreted in human milk. Caution should be exercised when Zantac is administered to a nursing mother. PHIitric DM: Safely and effectiveness In pediatricpatients have not been established. Use ki Ek4*rty HIMr. Ulcer healing rates in eldetfy patients (65 to 82 years ol age) were no different from those in younger age-groups. The Incidence rates for adverse events and laboratory abnormalities were also not different from those seen In other age-groups. ADVERSE REACTIONS: The following have been reported as events In clinical trials or in the routine management of patients treated with Zantac'. The relationship to Zantac therapy has been unclear to rrany cases. Headacte, sometimes severe, seems to be related to Zantac administration. Cntnl Nervous SntttK Rarely, malaise, dizziness, somnolence, Insomnia, and vertigo. Rare cases ol reversible mental confusion, agitation, depression, and hallucinations have been reported, predominantly In severely III elderly patients. Rare cases of reversible blurred vision suggestive of a change in accommodation have been reported. Rare reports of reversible Involuntary motor disturbances have been received. CiriiOMsaiku: As with other Hj-blockers, rare reports of arrhythmias such as tachycar- dia, bradycardla, atfoveritricularolock, and premature ventricular beats. GntrtWitUul: Constipation, diarrhea, nausea/vomiting, abdominal discomfort/pain, and rare reports of pancreatitis Huatte: In normal volunteers, SGPT values were Increased to at least twice the pretreatment levels in 6 of 12 subjects receiving 100 mg qid. Intravenously for 7 d»ys, and In 4 of 24 subjects receiving 50 mg qJ.d. Intravenously lor 5 days. There have been occasional reports of hepatitis, hepatocellular or hepatoonalicular or mixed, with or without jaundice. In such circumstances, ranltidine should be immediately discontinued. These events are usually reversible, but to exceedingly rare circumstances death has occurred. MualaskHtral:Rare reports of arthralgtas and myalgias. Hmntologlc: Blood count changes (teukooenia. grmdocytopenia, and rhrombocytopenia) have occurred In a few patients. These were usually reversible. Rare cases of agranulocyrosis, ca«»topenia, sometimes with nwrowliyiMplasia, art cases ofiacquired immune hemotytic anemia have been reported. FjfKrun: Controlled studies in animals and man have shown no stimulation of any pituitary hormone by Zantac and no antiandrogenlc activity, and dmetidlne-lnduced gyneco- mastia and impotence in hypersecretory patients have resolved when Zantac has been substituted. However, occasional cases of gynecomastia. impotence, and loss of libido have been reported In male patients receiving Zantac, but the Incidence did not differ from that in the general population.

Otkir: Rare cases of hypersensitivity reactions (e.g., bronchospasm, fever, rash, eosin optima), anaphylaxis, angioneurotic edema, and small increases In serum creatinine. OVEROOSABRThere has been limited experience with overdosage. Reported acute inges- tions of up to 18 g orally have been associated with transient adverse effects similar to those encountered In normal clinical experience (see ADVERSE REACTIONS). In addition, abnormalities of gait and hypotension have been reported. When overdosage occurs, the usual measures to remove unabsorbed material from the gastrointestinal tract, clinical monitoring, and supportive therapy should be employed. Studies in dogs receiving dosages of Zantac' In excess of 225 mo/kg per day have shown muscular tremors, vomiting, and rapid respiration. Single oral doses of 1.000 mg/kg In mice and rats were not lethal. Intravenous liSo values in mice and rats were 77 and 83 mg/kg, respectively.
