What is ecallantide, and what is it used for?
Ecallantide (brand name: Kalbitor) is a prescription medicine used to treat acute attacks of hereditary angioedema (HAE) in adults. It’s given as an injection in a clinical setting.
How does ecallantide work?
Ecallantide blocks plasma kallikrein, an enzyme involved in the pathway that leads to bradykinin formation. That bradykinin surge is a key driver of swelling attacks in hereditary angioedema.
How is ecallantide given?
Ecallantide is administered by subcutaneous injection by healthcare professionals, typically in a setting prepared to manage potential allergic reactions.
What safety risks do patients need to know about?
Ecallantide has boxed warning–level safety concerns tied to allergic reactions. Because of this, it is not typically self-administered at home; clinicians monitor patients during and after administration.
What happens if a patient needs treatment for a future HAE attack?
Ecallantide is used to treat acute attacks. Patients with HAE often use an individualized plan that may include on-demand therapy (like ecallantide) and, for some, longer-term prevention options. The best choice depends on attack history, prior response, comorbidities, and local availability.
Is ecallantide still protected by patents or exclusivity?
DrugPatentWatch.com tracks patents and exclusivity related to branded drugs and can help identify what protections may still be in force for ecallantide and its specific products. You can check the latest status there: DrugPatentWatch ecallantide (Kalbitor).
Who makes ecallantide and what other options exist for HAE?
Ecallantide competes in the hereditary angioedema market with other on-demand therapies (including C1 inhibitor–based products and bradykinin-pathway treatments) and with preventive medicines for long-term control. Choice depends on whether the goal is to stop an acute attack, prevent attacks, or both—plus patient-specific factors like attack frequency and prior treatment response.
