What is Icatibant Acetate?
Icatibant acetate, the active ingredient in Icatibant Fresenius, is a bradykinin B2 receptor antagonist presented as a subcutaneous formulation for subcutaneous use. It treats acute attacks of hereditary angioedema in patients with C1‑inhibitor deficiency. GNH USA supplies Icatibant Fresenius as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Icatibant Acetate used for?
Icatibant Fresenius is used to manage conditions driven by excessive bradykinin activity, especially hereditary angioedema. - Hereditary angioedema type I attacks: Rapid reduction of swelling and associated pain. - Hereditary angioedema type II attacks: Prompt relief of edema and restoration of airway patency. - Hereditary angioedema with normal C1‑inhibitor: Accelerates resolution of acute swelling episodes.
What are the side effects of Icatibant Acetate?
Icatibant Fresenius may cause a range of adverse reactions following subcutaneous administration.
Common Side Effects: - Injection site erythema: Redness at the injection site. - Injection site pain: Localized discomfort after dosing. - Injection site swelling: Mild to moderate edema around the needle entry. - Nausea: Transient feeling of queasiness. - Headache: Mild to moderate head pain.
Serious or Rare Side Effects: - Anaphylactic reaction: Rapid onset of systemic hypersensitivity requiring emergency care. - Severe hypotension: Marked drop in blood pressure that may lead to dizziness or syncope. - Laryngeal edema: Swelling of the throat that can compromise airway patency. - Stevens‑Johnson syndrome: Rare severe skin reaction with blistering and detachment.
What precautions apply to Icatibant Acetate?
Before using Icatibant Fresenius, consider the following safety measures. - Renal impairment: Monitor renal function and adjust therapy if needed. - Hepatic impairment: Use with caution in patients with liver disease. - Pregnancy: Safety not established; prescribe only if benefit outweighs potential risk. - Breastfeeding: Unknown excretion in milk; evaluate risk versus benefit. - Concomitant ACE inhibitors: May increase bradykinin levels and risk of angioedema. - Store at 2-8°C: Keep refrigerated, protect from light, do not freeze or shake.
What does Icatibant Acetate interact with?
Icatibant Fresenius can interact with other medicines that influence bradykinin pathways or vascular tone.
Major Interactions (Avoid): - ACE inhibitors: Heightened risk of angioedema; avoid co‑administration. - Angiotensin II receptor blockers (ARBs): May augment bradykinin effects; avoid. - Estrogen‑containing contraceptives: Can exacerbate hereditary angioedema; avoid.
Moderate Interactions (Monitor Closely): - C1‑inhibitor concentrates: Potential reduction in therapeutic effect; monitor response. - Other bradykinin‑targeting agents: Additive pharmacodynamic effect; observe for excessive hypotension. - Non‑steroidal anti‑inflammatory drugs (NSAIDs): May increase local injection‑site reactions; watch for irritation.
