What is Catapres?

Catapres (Clonidine) belong to the class of central alpha agonists. This medication is prescribed to treat Hypertension and is primarily recommended in cardiovascular patients for the management of high blood pressure and pain in cancer patients.

Uses Of Catapres

High blood pressure (Hypertension) is treated by the Alpha Agonist drug that binds to the alpha receptors and dilates the vessels. Clonidine belongs to the Alpha agonists class and is prescribed wildly for this blood pressure-lowering effect.

How does it works?

Clonidine binds to alpha-2 adrenergic receptors in the central nervous system, leading to reduced sympathetic activity, vasodilation, and decreased heart rate, resulting in lowered blood pressure. Its interaction with alpha-2 receptors in the spinal cord helps inhibit pain signal transmission, making it effective for managing severe pain, particularly in cancer patients.

How to take it?
