Description

Trimeprazine (also known as Alimemazine), a phenothiazine used as antipsychotic drug. This drug is used in Russia under brand name TERALIGEN and has anti-histamine, sedative, and anti-emetic (anti-nausea) effects. Teraligen is used to treat neurosis, depression and anxiety of different origins. It prevents and relieves allergic conditions, which cause pruritus and urticaria by blocking histamine produced by the body during an allergic reaction. Trimeprazine competes with free histamine for binding at HA-receptor sites. This antagonizes the effects of histamine on HA-receptors, leading to a reduction of the negative symptoms brought on by histamine HA-receptor binding. Trimeprazine is not approved for use in humans in the United States. Nevertheless, combination of alimemazine and prednisolone (commonly sold under the brand name Temaril-P) is licensed as an antipruritic and antitussive in dogs.

Sample Use Guides

In Vivo Use Guide
Teraligen is administrated orally 3-4 times a day. Hypnotic effect for adults: initial dose is 5-10 mg/day. Anxiolytic effect: initial dose is 60-80 mg/day. Antipsychotic effect: initial dose 200-400 mg/day. Sedative effect for chidren: initial dose 2.5-5 mg/day Symptomatic treatment of allergic reactions: initial dose 5-20 mg/day Anxiolytic effect: initial dose 20-40 mg/day
Route of Administration: Oral
In Vitro Use Guide
Trimeprazine (TMP), a phenothiazine used as antipsychotic drug, was previously shown to induce a decrease in thyroid hormone serum levels in rats. Different mechanisms might be involved, mainly (i) a central mechanism, involving a reduction of thyroid-stimulating hormone (TSH) secretion; (ii) a peripheral mechanism, acting upon the synthesis of thyroid hormones, by inhibition of thyroperoxidase (TPO) or trapping of molecular iodine present in the thyroid gland. In vitro studies concerned TMP, and its three main metabolites: trimeprazine sulphoxide (TSO), N-desmethyl trimeprazine (NDT), and 3-hydroxy-trimeprazine (3-OHT). TMP and TSO expressed a high affinity for iodine in vitro, contrary to NDT, which did not complex iodine. Only 3-OHT inhibited TPO in vitro.
