Glypressin (Terlipressin Acetate)

Glypressin is administered intravenously for conditions that benefit from vasopressin‑like activity. It is typically considered in the following clinical contexts:

• Management of acute bleeding from esophageal or gastric varices.
• Treatment of hepatorenal syndrome in patients with advanced liver disease.
• Support of blood pressure in selected cases of septic shock.
• Control of refractory hypotension when conventional vasopressors are insufficient.
• Adjunct therapy in certain surgical or interventional procedures to reduce portal hypertension.

Side effects of Glypressin vary in frequency and severity. Common adverse reactions are usually mild and transient, while serious events are less frequent but require prompt medical attention.

Common

• Headache
• Nausea or vomiting
• Abdominal discomfort
• Flushing or warmth sensation
• Mild hypertension
• Transient increase in heart rate

Serious

• Severe hypertension or hypertensive crisis
• Cardiac arrhythmias
• Ischemic complications (e.g., myocardial ischemia)
• Peripheral ischemia or gangrene
• Acute renal impairment
• Severe abdominal pain indicating mesenteric ischemia

Glypressin should be used with caution and under close monitoring. Important precautions include:

• Assess cardiovascular status before initiation, especially in patients with coronary artery disease.
• Monitor blood pressure and heart rate continuously during infusion.
• Evaluate renal function, as terlipressin can affect renal perfusion.
• Use carefully in patients with peripheral vascular disease or a history of ischemic events.
• Adjust or discontinue therapy if severe hypertension or signs of ischemia develop.
• Consider potential effects on fetal circulation; avoid use during pregnancy unless clearly indicated.

Glypressin may interact with other medications that influence vascular tone or renal function. Interactions are grouped as follows:

Avoid

• Other potent vasopressors (e.g., norepinephrine, phenylephrine) that may exacerbate hypertension.
• Drugs that cause vasoconstriction such as ergot alkaloids.
• Concomitant use with high‑dose catecholamines without specialist guidance.

Use with caution

• Diuretics, which may amplify changes in blood volume and pressure.
• ACE inhibitors or ARBs, as combined effects on renal perfusion can occur.
• Anticoagulants, because altered hemodynamics may affect bleeding risk.
• Anesthetics that influence cardiovascular stability during surgery.
