What is Amitriptyline
Amitriptyline is a tricyclic antidepressant also having a pronounced sedative, hypnotic and anti-anxiety effect. Amitriptyline helps in eliminating night urinary incontinence and reducing appetite. Besides, it has some analgesic action. It is used in addition to other medications for pain. When used in general anesthesia, it reduces blood pressure and body temperature.
Each amitriptyline tablet contains the active substance of amitriptyline hydrochloride, 10mg, and excipients: lactose, corn starch, calcium phosphate dibasic, gelatin, talc, magnesium stearate, silicon dioxide colloidal anhydrous, polyethylene glycol 6000, Opadry Blue (hydroxypropyl methylcellulose, titanium dioxide, talc, polyethylene glycol, brilliant blue).
At the moment, amitriptyline is considered the most reliable and affordable tricyclic antidepressant. In the tricyclic class, amitriptyline is second only to trimipramine and fluorocycin by the strength of the sedative, hypnotic and anti-anxiety effect. Amitriptyline 10mg is taken by mouth. Antidepressant effect develops within 2-3 weeks after the beginning of application.
The mechanism of antidepressant action is associated with an increase in the concentration of noradrenaline and / or serotonin in the central nervous system (CNS) (a decrease in their reverse absorption).
Amitriptyline has the properties of antiarrhythmic drugs like e.g. quinidine. In therapeutic doses, it slows down the ventricular conduction (in case of an overdose it can cause severe intraventricular blockade).
