Fenoxene Capsule (Phenoxybenzamine)
Fenoxene® contains phenoxybenzamine, a long-acting α‑adrenergic antagonist prescribed to manage pheochromocytoma-related hypertension and reduce associated symptoms like excessive sweating. Its extended effect supports stable blood pressure control, particularly beneficial pre- and post-surgery.
Fenoxene® 10 mg capsules contain phenoxybenzamine, a non-selective alpha-adrenergic blocker used to manage high blood pressure caused by pheochromocytoma, a rare adrenal tumor. It helps prevent dangerous blood pressure spikes before surgery and supports long-term control of symptoms like palpitations, sweating, and headaches.
This medicine works by relaxing blood vessels and improving blood flow, making it especially effective for pre-surgical stabilization and certain circulatory conditions. Trusted by doctors, Fenoxene® offers a long-acting formula for consistent results and fewer daily doses.
Whether you're preparing for surgery or managing rare forms of hypertension, Fenoxene® provides a reliable and effective option. Each box contains 10 mg oral capsules, manufactured by Samarth Life Sciences—a well-known Indian pharmaceutical brand.
