Estazolam (Oral)

Estazolam is a treatment used on patients suffering from insomnia and works by depressing the central nervous system.


Estazolam is a part of the medicine group known as benzodiazepines. This treatment works on the central nervous system of the patient to slow down the nervous system, enabling the patient to become tired and drowsy.
