Description

Eperisone is a centrally acting muscle relaxant belonging to the class of benzylamines. It is a key active pharmaceutical ingredient (API) valued for its efficacy in relieving muscle stiffness and spasticity associated with various neurological and musculoskeletal conditions. This compound is primarily utilized by pharmaceutical manufacturers in the production of prescription medications. Eperisone CAS NO 64840-90-0 is supplied to meet the stringent quality requirements of the global pharmaceutical industry.

Application

• Pharmaceutical API: Primary use as the active ingredient in muscle relaxant formulations for oral tablets and capsules.
• Treatment of Spasticity: Used in medications for conditions such as cervical spondylosis, lumbar spinal canal stenosis, and other disorders causing muscle hypertonia.
• Musculoskeletal Pain Management: Incorporated into drugs aimed at relieving pain associated with muscle tension and stiffness.
• Post-Stroke and Neurological Care: Applied in therapeutic regimens for managing spasticity resulting from cerebrovascular accidents or other neurological damage.
• Generic Drug Manufacturing: Sourced by generic pharmaceutical companies for the production of bioequivalent versions of branded muscle relaxants.
• Clinical Research: Serves as a reference standard or raw material in preclinical and clinical studies for new neurological therapies.
