Solution for injection. Clear, colourless liquid.

4.1 Therapeutic indications Glypressin is indicated in the treatment of bleeding oesophageal varices.4.2 Posology and method of administration **Posology** In acute variceal bleeding: **Adults:**Initially an i.v. injection of 2 mg Glypressin is given every 4 hours. The treatment should be maintained until bleeding has been controlled for 24 hours, but up to a maximum of 48 hours. After the initial dose, the dose can be adjusted to 1 mg i.v. every 4 hours in patients with body weight < 50 kg or if adverse effects occur. **Paediatric population:** There is no relevant use of Glypressin in paediatric population. **Method of administration** Intravenous injection use4.3 Contraindications Contraindicated in pregnancy. Hypersensitivity to terlipressin acetate or any of the excipients listed in section 6.1.4.4 Special warnings and precautions for use Blood pressure, heart rate and fluid balance should be monitored during treatment. To avoid local necrosis at the injection site, the injection must be given i.v. Caution should be exercised in treating patients with hypertension or recognised heart disease. In patients with septic shock with a low cardiac output Glypressin should not be used. **Torsade de pointes** During clinical trials and post-marketing experience, several cases of QT interval prolongation and ventricular arrhythmias including “Torsade de pointes” have been reported (see section 4.8). In most cases, patients had predisposing factors such as basal prolongation of the QT interval, electrolyte abnormalities (hypokalemia, hypomagnesemia) or medications with concomitant effect on QT prolongation. Therefore, extreme caution should be exercised in the use of terlipressin in patients with a history of QT interval prolongation, electrolyte abnormalities, or concomitant medications that can prolong the QT interval (see section 4.5). Children and the elderly: Particular caution should be exercised in the treatment of children and elderly patients, as experience is limited in these groups. There is no data available regarding dosage recommendation in these special patient categories.4.5 Interaction with other medicinal products and other forms of interaction The hypotensive effect of non-selective beta-blockers on the portal vein is increased with terlipressin. Concomitant treatment with medicinal products with a known bradycardic effect (e.g. propofol, sufentanil) may lower the heart rate and cardiac output. These effects are due to reflexogenic inhibition of cardiac activity via the vagus nerve due to the elevated blood pressure. Terlipressin can trigger “torsade de pointes” (see sections 4.4 and 4.8). Therefore, extreme caution should be exercised in the use of terlipressin in patients with concomitant medications that can prolong the QT interval, such as class IA and III antiarrhythmics, erythromycin, certain antihistamines and tricyclic antidepressants or medications that may cause hypokalaemia or hypomagnesemia (e.g. some diuretics).4.6 Fertility, pregnancy and lactation **Pregnancy** Treatment with Glypressin during pregnancy is contraindicated (ref. 4.3 and 5.3). Glypressin has been shown to cause uterine contractions and increased intrauterine pressure in early pregnancy and may decrease uterine blood flow. Glypressin may have harmful effects on pregnancy and foetus. Spontaneous abortion and malformation have been shown in rabbits after treatment with Glypressin. **Breast-feeding** It is not known whether terlipressin is excreted in human breast milk. The excretion of terlipressin in milk has not been studied in animals. A risk to the suckling child cannot be excluded. A decision on whether to continue/discontinue breast-feeding or to continue/discontinue therapy with terlipressin should be made taking into account the benefit of breast-feeding to the child and the benefit of terlipressin therapy to the woman.4.7 Effects on ability to drive and use machines No studies on the effects on the ability to drive and use machines have been performed.4.8 Undesirable effects ***Table: Frequency of undesirable effects*** | | | | | | --- | --- | --- | --- | | **SYSTEM ORGAN CLASS** | **Frequency** | | | | **COMMON** ≥1/100 to <1/10 | **UNCOMMON** ≥ 1/1,000 to < 1/100 | **RARE** ≥1/10,000 to ≤1/1,000 | | **Metabolism and nutrition disorders** | | Hyponatraemia if fluid not monitored | | | **Nervous system Disorders** | Headache | | | | **Cardiac** **disorders** | Bradycardia | Atrial fibrillation Ventrical extrasystoles Tachycardia Chest pain Myocardial infarction Fluid overload with pulmonary oedema Torsade de pointes Cardiac failure | | | **Vascular** **disorders** | Peripheral vasoconstriction Peripheral ischaemia Facial pallor Hypertension | Intestinal ischaemia Peripheral cyanosis Hot flushes | | | **Respiratory** **thoracic and mediastinal disorders** | | Respiratory distress Respiratory failure | Dyspnoea | | **Gastrointestinal** **disorders** | Transient abdominal cramps Transient diarrhoea | Transient nausea Transient vomiting | | | **Skin and subcutaneous** **tissue disorders** | | Skin necrosis | | | **Pregnancy, puerperium and perinatal conditions** | | Uterine hypertonus Uterine ischemia | | | **General** **disorders and administration site disorders** | | Injection site necrosis | | **Reporting of suspected adverse reactions** Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme, website: www.mhra.gov.uk/yellowcard.4.9 Overdose The recommended dose (2mg/4 hours) should not be exceeded as the risk of severe circulatory adverse effects is dose-dependent.

5.1 Pharmacodynamic properties Pharmacotherapeutic group: Posterior pituitary lobe hormones (vasopressin and analogues) (H 01 BA 04) Glypressin® may be regarded as a circulating depot of lysine vasopressin. Following intravenous injection, three glycyl moieties are enzymatically cleaved from the N-terminus to release lysine vasopressin. The slowly released vasopressin reduces blood flow in the splanchnic circulation in a prolonged manner, thereby helping to control bleeding from ruptured oesophageal varices.5.2 Pharmacokinetic properties Glypressin® is administered by bolus intravenous injection. It shows a biphasic plasma level curve which indicates that a two compartment model can be applied. The half-life of distribution (T1/2α) is about 8 -10 minutes. The half-life of elimination (T1/2β) is about 50 -70 minutes. Lysine vasopressin reaches maximum plasma levels about 1 - 2 hours following intravenous administration and has a duration of activity of 4 - 6 hours.5.3 Preclinical safety data There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
