Klonazepāms

Clonazepam is a long-acting benzodiazepine that produces primarily anxiolytic effects alongside anticonvulsant, sedative, muscle relaxant, and hypnotic properties. Patented in 1960 and first marketed in the United States by Roche in 1975, it is widely prescribed for the treatment of panic disorder, anxiety disorders, and seizures. Now available as a generic medication, it remains one of the most commonly prescribed benzodiazepines, with millions of prescriptions written internationally each year.
