Amitriptyline hydrochloride is used to treat depression and other mental disorders, as stated by WebMD. It is the generic name for a prescription medicine with known calming effects, which is believed to be caused by the disruption of serotonin and/or norepinephrine absorption.
Amitriptyline hydrochloride, or amitriptyline HCL, is taken in tablet form. The severity of the condition and the level of response to the medication generally dictates the dosage. The drug is administered to depressed patients to induce a happier state of mind, reduce anxiety and agitation, improve sleep and boost vitality.
