Description
Curator's Comment: description was created based on several sources, including http://www.rxlist.com/elavil-drug.htm https://www.ncbi.nlm.nih.gov/pubmed/23235671; https://www.ncbi.nlm.nih.gov/pubmed/11157426; http://www.ncbi.nlm.nih.gov/pubmed/16871467; http://www.ncbi.nlm.nih.gov/pubmed/2578912; http://www.ncbi.nlm.nih.gov/pubmed/?term=15943846

Amitriptyline is a derivative of dibenzocycloheptadiene and a tricyclic antidepressant (TCA) and is mainly used to treat symptoms of depression. It works on the central nervous system (CNS) by inhibiting the membrane pump mechanism responsible for uptake of norepinephrine and serotonin in adrenergic and serotonergic neurons. Amitriptyline has been frequently used as an active comparator in clinical trials on newer antidepressants. It is rarely used as a first-line antidepressant nowadays due to its high degree of toxicity in overdose and generally poorer tolerability than the newer antidepressants.

Sample Use Guides

In Vivo Use Guide
For outpatients, 75 mg of amitriptyline HCl a day in divided doses. If necessary, this may be increased to a total of 150 mg per day. An alternate method of initiating therapy in outpatients is to begin with 50 to 100 mg amitriptyline HCl at bedtime. This may be increased by 25 or 50 mg as necessary in the bedtime dose to a total of 150 mg per day. Hospitalized patients may require 100 mg a day initially. This can be increased gradually to 200 mg a day if necessary up to 300 mg a day. Not recommended for patients under 12 years of age
Route of Administration: Oral
In Vitro Use Guide
Amitriptyline was used at 40 uM in isolated rat hepatocytes for 60,120,180 min.

PRIMARY Description: Colourless crystals or a white or almost white powder; odourless or almost odourless. Solubility: Soluble in 1 part of water and in 1.5 parts of ethanol (~750 g/l) TS; practically insoluble in ether R. Category: Antidepressant. Storage: Amitriptyline hydrochloride should be kept in a tightly closed container, protected from light. Additional information: Amitriptyline hydrochloride has a bitter and burning taste that is followed by a sensation of numbness. Even in the absence of light, Amitriptyline hydrochloride is gradually degraded on exposure to a humid atmosphere, the decomposition being faster at higher temperatures. Definition: Amitriptyline hydrochloride contains not less than 99.0% and not more than 101.5% of C20H23N,HCl, calculated with reference to the dried substance.
