Ranitidine 150mg/10ml Oral Solution Ranitidine Hydrochloride 167.5mg/10ml (equivalent to Ranitidine 150mg/10ml) Ethanol = 810mg/10ml Sorbitol = 1.4g/10ml Sodium = 22mg/10ml For full list of excipients see Section 6.1 Oral Solution A straw coloured liquid with odour of mint Ranitidine is indicated for the treatment of duodenal ulcer and benign gastric ulcer, including that associated with non-steroidal anti-inflammatory agents. In addition, ranitidine is indicated for the prevention of NSAID (including aspirin) associated duodenal ulcers. Ranitidine is also indicated for the treatment of post-operative ulcer, Zollinger-Ellison Syndrome and treatment of oesophageal reflux disease including prevention of relapse. Ranitidine is indicated for the following conditions where reduction of gastric secretion and acid output is desirable; - the prophylaxis of gastro-intestinal haemorrhage from stress ulceration in seriously ill patients - the prophylaxis of recurrent haemorrhage in patients with bleeding peptic ulcers - before general anaesthesia in patients considered to be at risk of acid aspiration (Mendelson's Syndrome), particularly obstetric patients during labour. Children (3 to 18 years) - Short term treatment of peptic ulcer - Treatment of gastro-oesophageal reflux, including reflux oesophagitis and symptomatic relief of gastro-oesophageal reflux disease. See section 4.4. Special warnings and precautions for use. Route of administration: Oral Adults (including the elderly): Treatment of duodenal and gastric ulcer: The usual dosage is 150mg twice daily, taken in the morning and evening or a single bedtime dose of 300mg. It is not necessary to time the dose in relation to meals. This may be increased to ranitidine 300mg twice daily without an increased incidence of unwanted effects. In most cases of duodenal ulcer, benign gastric ulcer and post operative ulcer, healing occurs in four weeks. Healing usually occurs after a further four weeks of treatment in those patients whose ulcers have not fully healed after the initial course of therapy. Maintenance treatment at a reduced dosage of 150mg at bedtime is recommended for patients who have responded to short term therapy, particularly those with a history of recurrent ulcer. Treatment of ulcers following NSAID therapy or associated with continuing NSAIDS In ulcers following non-steroidal anti-inflammatory drug therapy or associated with continued non-steroidal anti-inflammatory drugs, eight to twelve weeks treatment may be necessary with 150mg bd or 300mg nocte. Prevention of NSAID induced ulcers: For the prevention of non-steroidal anti-inflammatory drug associated duodenal ulcers, ranitidine 150mg twice daily may be given concomitantly with non-steroidal anti-inflammatory drug therapy. Treatment of oesophageal reflux disease including prevention of relapse: In the management of oesophageal reflux disease, the recommended course of treatment is either 150mg twice daily or 300mg at bedtime for up to eight weeks or if necessary twelve weeks. In patients with moderate to severe oesophagitis, the dosage of ranitidine may be increased to 150mg four times daily for up to twelve weeks. The increased dose has not been associated with an incidence of unwanted effects. For the long-term management of oesophagitis the recommended adult oral dose is 150mg twice daily. Ranitidine is not indicated in patients with complications of reflux oesophagitis e.g. oesophageal stricture or Barrett's oesophagous. In keeping with the recommended clinical practice, it is advisable that patients on long term maintenance therapy receive regular routine assessments by their practitioner (see Section 4.4) Treatment of Zollinger-Ellison Syndrome: In patients with Zollinger-Ellison Syndrome, the starting dose is 150mg three times daily and this may be increased as necessary. Patients with this syndrome have been given increasing doses up to 6g per day and these doses have been well tolerated. Prophylaxis of haemorrhage from stress ulceration in seriously ill patients or prophylaxis of recurrent haemorrhage in patients bleeding from peptic ulceration: In the prophylaxis of haemorrhage from stress ulceration in seriously ill patients or the prophylaxis of recurrent haemorrhage in patients bleeding from peptic ulceration, treatment with Ranitidine 150mg/10ml Oral Solution b.d. may be substituted for Ranitidine Injection once oral feeding commences in patients considered to still be at risk from these conditions. Prophylaxis of acid aspiration (Mendelson's Syndrome) In patients thought to be at risk of acid aspiration syndrome an oral dose of 150mg can be given two hours before induction of general anaesthesia and preferably also 150mg the previous evening. In obstetric patients at commencement of labour, an oral dose of 150mg may be given followed by 150mg at six hourly intervals. It is recommended that since gastric emptying and drug absorption are delayed during labour, any patient requiring emergency general anaesthesia should be given, in addition, a non-particulate antacid (e.g. sodium citrate) prior to induction of anaesthesia. The usual precautions to avoid acid aspiration should also be taken. Renal Insufficiency Accumulation of ranitidine with resulting elevated plasma concentration will occur in patients with severe renal impairment. Accordingly, it is recommended that the daily dose of ranitidine in such patients should be 150mg at night for 4 - 8 weeks. In patients with creatinine clearance of less than 50ml/min the usual dose is 150mg nightly. In patients on dialysis, dosage should be given on completion of dialysis. Children (3 to 11 years) See Section 5.2 Pharmacokinetic Properties - Special Patient Populations. Ranitidine syrup contains 8%w/v ethanol. Therefore an alternative formulation of ranitidine may be considered necessary for at-risk groups, including children (see section 4.4 Special warnings and precautions for use). Peptic Ulcer Acute Treatment The recommended oral dose for the treatment of peptic ulcer in children is 4 mg/kg/day to 8 mg/kg/day administered as two divided doses to a maximum of 300 mg ranitidine per day for a duration of 4 weeks. For those patients with incomplete healing, another 4 weeks of therapy is indicated, as healing usually occurs after eight weeks of treatment. Gastro-Oesophageal Reflux The recommended oral dose for the treatment of gastro-oesophageal reflux in children is 5 mg/kg/day to 10 mg/kg/day administered as two divided doses in a maximum dose of 600 mg (the maximum dose is likely to apply to heavier children or adolescents with severe symptoms). Safety and efficacy in new-born patients has not been established. Known hypersensitivity to ranitidine or any of the excipients in the formulation. Treatment with a histamine H2 -antagonist may mask symptoms associated with carcinoma of the stomach and may therefore delay diagnosis of the condition. Accordingly, where gastric ulcer has been diagnosed or in patients of middle age and over with new or recently changed dyspeptic symptoms the possibility of malignancy should be excluded by endoscopy and biopsy before therapy with ranitidine is instituted. In keeping with the recommended clinical practice, it is advisable that patients on long term maintenance therapy receive regular routine assessments by their practitioner (see Section 4.2) Ranitidine is excreted via the kidney and so plasma levels of the drug are increased in patients with severe renal impairment. The dosage should be adjusted as detailed in Section 4.2 under 'Renal Insufficiency'. Regular supervision of patients who are taking non-steroidal anti-inflammatory drugs concomitantly with ranitidine is recommended, especially in the elderly and those with a history of peptic ulcer. Patients on prolonged treatment (particularly more than one year) should be kept under regular surveillance. Although clinical reports of acute intermittent porphyria associated with ranitidine administration have been rare and inconclusive, ranitidine should be avoided in patients with a history of this condition. Rates of healing ulcers in clinical trial patients aged 65 and over have not been found to differ from those in younger patients. Additionally, there was no difference in the incidence of adverse effects. Physicians should be aware that on rare occasions immune system reactions (rash and hypereosinophilia) have been reported on reintroduction of ranitidine, even months or years after withdrawal. In patients such as the elderly, persons with chronic lung disease, diabetes or the immunocompromised, there may be an increased risk of developing community acquired pneumonia. A large epidemiological study showed an increased risk of developing community acquired pneumonia in current users of ranitidine alone H2 receptor antagonists versus those who had stopped treatment, with an observed adjusted relative risk increase of 1.82 (95% CI 1.26 - 2.64). Excipient Information Ethanol - This product contains 8%w/v ethanol (alcohol), i.e. up to 405mg per 5ml spoonful which is equivalent to about 11ml of beer or 5ml of wine. It is harmful for those suffering from alcoholism. It should be taken into account in pregnant or lactating women, children (see section 4.2) and high risk groups (those suffering from alcoholism, liver disease, epilepsy, brain injury or disease). It may modify or increase the effect of other medicines. The amount of alcohol in this medicinal product may impair the ability to drive or use machines (see Section 4.7). Alternative formulation of ranitidine may be considered preferential in these populations. Sorbitol - The product contains 700mg per 5ml spoonful of sorbitol which is a source of 175mg fructose. Patients with rare hereditary problems of fructose intolerance should not take this medicine. It can also cause stomach upset and diarrhoea in large amounts. Sodium -The product contains 11mg of sodium per 5ml spoonful. Ranitidine has the potential to affect the absorption, metabolism or renal excretion of other drugs. The altered pharmacokinetics may necessitate dosage adjustment of the affected drug or discontinuation of treatment. Interactions occur by several mechanisms including: 1) Inhibition of cytochrome P450-linked mixed function oxygenase system: Ranitidine at usual therapeutic doses does not potentiate the action of drugs which are inactivated by this enzyme system such as diazepam, lidocaine, phenytoin, propranolol and theophylline. There have been reports of altered prothrombin time with coumarin anticoagulants (e.g. warfarin). Due to the narrow therapeutic index, close monitoring of increased or decreased prothrombin time is recommended during concurrent treatment with ranitidine. 2) Competition for renal tubular secretion: Since ranitidine is partially eliminated by the cationic system, it may affect the clearance of other drugs eliminated by this route. High doses of ranitidine (e.g. such as those used in the treatment of Zollinger-Ellison syndrome) may reduce the excretion of procainamide and N-acetylprocainamide resulting in increased plasma levels of these drugs. 3) Alteration of gastric pH The bioavailability of certain drugs may be affected. This can result in either an increase in absorption (e.g. triazolam, midazolam, glipizide, raltegravir) or a decrease in absorption (e.g. ketoconazole, itraconazole, atazanavir, delavirdine, gefitinib, lapatinib, cefpodoxime). There is no evidence of an interaction between ranitidine and amoxicillin and metronidazole. If high doses (2g) of sucralfate are co-administered with ranitidine the absorption of the latter may be reduced. This effect is not seen if sucralfate is taken after an interval of 2 h. Ranitidine should not be administered during pregnancy or lactation unless considered essential by the physician. Ranitidine crosses the placenta but therapeutic doses administered to obstetric patients in labour or undergoing caesarean section have been without any adverse effect on labour, delivery or subsequent neonatal progress. Ranitidine is also excreted in human breast milk. Like other drugs, ranitidine should only be used during pregnancy and nursing if considered essential. The amount of alcohol in this medicinal product may impair the ability to drive or use machines (see Section 4.4). In the case of breast symptoms in men, it may be necessary to discontinue treatment to establish the underlying cause; however some cases have been resolved on continued therapy. The safety of ranitidine has been assessed in children aged 0 to 16 years with acid related disease and was generally well tolerated with an adverse event profile resembling that in adults. There are limited long term safety data available, in particular, regarding growth and development. Ranitidine is very specific in action and accordingly no particular problems are expected following overdosage with the drug. Symptomatic and supportive therapy should be given as appropriate. If need be, the drug may be removed from the plasma by haemodialysis. ATC Code: A02 BA02 Ranitidine is a specific, rapidly acting H2 -antagonist. It inhibits basal and stimulated secretion of gastric acid, reducing both the volume of the acid and pepsin content of the secretion. Ranitidine has a relatively long duration of action and a single 150mg dose effectively suppresses gastric acid secretion for twelve hours. The bioavailability of ranitidine is consistently about 50%. Absorption of ranitidine after oral administration is rapid and peak plasma concentrations are usually achieved 2-3 hours after administration. Absorption is not significantly impaired by foods or antacids. Ranitidine is not extensively metabolised. Elimination of the drug is primarily by tubular secretion. The elimination half-life of ranitidine is 2-3 hours. In balance studies with 150mg 3H-ranitidine 60-70% of an oral dose was excreted in urine and 26% in faeces. Analysis of urine excreted in the first 24 hours after dosing showed that 35% of the oral dose was eliminated unchanged. About 6% of the dose is excreted as the N-oxide, 2% as the S-oxide, 2% as desmethyl ranitidine and 1-2% as the furoic acid analogue. Special Patient Populations Children (3 years and above) Limited pharmacokinetic data have shown that there are no significant differences in half-life (range for children 3 years and above: 1.7 - 2.2 h) and plasma clearance (range for children 3 years and above: 9 - 22 ml/min/kg) between children and healthy adults receiving oral ranitidine when correction is made for body weight. Extensive studies have been carried out in animals. The pharmacology of ranitidine hydrochloride shows it to be a surmountable H2 receptor antagonist which produces an inhibition of gastric acid secretion. Extensive toxicological investigations have been conducted which predicted a very safe profile for clinical use. This safety has since been confirmed by extensive use in patients for many years.

Farmakoterapijska skupina i djelovanje Peptoran je pouzdan antiulkusni lijek iz skupine antagonista H2-receptora. U propisanim dozama snažno koči bazalnu i stimuliranu sekreciju želučane kiseline te znatno smanjuje količinu želučanog soka i sadržaj pepsina. Antisekretorno djelovanje zbiva se na razini želučanih parijetalnih stanica mehanizmom selektivne blokade histaminskih H2-receptora. Terapijski učinak Peptorana započinje brzo i traje razmjerno dugo. Najviša se koncentracija u plazmi postiže dva do tri sata nakon oralne primjene. Pojedinačna doza od 150 mg uspješno koči kiselu želučanu sekreciju tijekom 12 sati. Jedna večernja doza od 300 mg dostatna je za održavanje povišene pH vrijednosti tijekom cijele noći i sljedećeg dana. Način i mjesto izdavanja Na recept Rok valjanosti Označen je na pakovanju. Lijek se ne smije rabiti nakon isteka roka valjanosti. Čuvati pri temperaturi do 25 °C. LIJEK VALJA ČUVATI IZVAN DOSEGA DJECE! Primjena Terapijske indikacije Peptoran se primjenjuje u bolesnika s ulkusom na dvanaesniku, benignim želučanim ulkusom, Zollinger-Ellisonovim sindromom, refluksnim ezofagitisom, kroničnom epizodnom dispepsijom i u ostalim stanjima s hiperaciditetom. Doziranje Ukoliko liječnik ne odredi drukčije, Peptoran se uzima prema uputi. Odrasli Peptički ulkus U liječenju akutnog ulkusa na dvanaesniku i benignoga želučanog ulkusa primjenjuje se neovisno o uzimanju obroka jedna tableta po 150 mg dvaput na dan (ujutro i navečer) ili jedna tableta po 300 mg navečer prije spavanja. Liječenje traje četiri do osam tjedana. Nakon cijeljenja ulkusa prelazi se na dozu održavanja od 150 mg na dan (prije spavanja) tijekom 12 mjeseci, uz redovite endoskopske pretrage svaka četiri mjeseca. Refluksni ezofagitis Daje se jedna tableta po 150 mg dvaput na dan ili jedna tableta po 300 mg navečer prije spavanja tijekom osam tjedana. Zollinger- Ellisonov sindrom U liječenju navedenog sindroma daje se jedna tableta po 150 mg triput na dan (ujutro, u podne i prije spavanja). Ako ustreba, doza se može povećati na 600 do 900 mg i više na dan (najviše 6 g na dan). Kronična epizodna dispepsija Daje se jedna tableta po 150 mg dvaput na dan tijekom šest tjedana. Preanestetička medikacija Bolesnicima s hipersekrecijom, za prevenciju aspiracije kiselog želučanog sadržaja tijekom operacije (Mendelsonov sindrom), dva se sata prije operacije oralno daje 150 mg Peptorana. Jedna se tableta Peptorana po 150 mg može davati po potrebi svakih 6 sati tijekom porođaja ili prije carskog reza. Djeca Peptički ulkus u djece do 16 godina liječi se s 2 do 4 mg/kg dvaput na dan. Najveća dnevna doza iznosi 300 mg. Doziranje u bolesnika s oštećenjem bubrežne funkcije Bolesnicima s ograničenom bubrežnom funkcijom, u kojih je klirens kreatinina manji od 50 ml/min, daje se 150 mg navečer prije spavanja. Predoziranje Iako je iskustvo s ranitidinom nedostatno, zbog veoma specifičnog djelovanja nakon predoziranja se ne očekuju posebni problemi, te liječenje treba biti simptomatsko i suportivno. Ako ustreba, lijek se može ukloniti iz plazme hemodijalizom. Mjere opreza Antagonisti H2-receptora mogu prikriti simptome karcinoma želuca pa prije početka liječenja želučanog ulkusa treba isključiti maligni proces. Kontraindikacije Peptoran je kontraindiciran u bolesnika preosjetljivih na ranitidin. Posebna upozorenja U bolesnika s oštećenjem bubrežne funkcije potreban je oprez. U bolesnika s ograničenom bubrežnom funkcijom dozu treba prilagoditi bubrežnom oštećenju jer se u protivnom može povećati plazmatska koncentracija lijeka. Peptoran treba izbjegavati u bolesnika s anamnezom akutne porfirije. Trudnoća i dojenje Zbog nedostatnih iskustava Peptoran se tijekom trudnoće i dojenja primjenjuje samo ako je nužno. Može se davati tijekom porođaja jer terapijske doze ne mijenjaju njegov tijek, a ni kasniji oporavak majke i novorođenčeta. Nuspojave Nuspojave Peptorana su blage, rijeke i prolazne. Moguće su glavobolja, proljev, opstipacija, vrtoglavica, pospanost, mučnina ili povraćanje, te kožni osip. Peptoran veoma rijetko može uzrokovati bradikardiju, koja nije klinički signifikantna, AV blok, te konfuziju koja je vjerojatnija u ozbiljno bolesnih osoba ili u bolesnika s bubrežnim oštećenjem. Alergijske su reakcije (uritkarija, angioedem, vrućica, bronhospazam, hipotenzija, anafilaktički šok) iznimno rijetke. Reverzibilne su hematološke promjene (leukopenija, trombocitopenija, pancitopenija, agranulocitoza) zapažene u iznimno rijetkim slučajevima, a vjerojatnije su u ozbiljno bolesnih osoba i u bolesnika liječenih lijekovima koji suprimiraju koštanu srž. O svakoj nuspojavi valja obavijestiti svog liječnika ili ljekarnika. Interakcije Ranitidin nema klinički signifikantnih interakcija. Ne djeluje na jetreni citokrom P450 i stoga ne ometa oksidativne enzimatske procese, te nema interakcija s lijekovima koji metaboliziraju tim putem. Peptoran može blago i prolazno promijeniti rezultate funkcionalnih jetrenih testova. Napomene PLIVA d.d. Ulica grada Vukovara 49, 10 000 Zagreb, Hrvatska
