Pharmacokinetics of trazodone after different routes of administration. 1981

A Rurak, and M Melzacka, and L Danek

Pharmacokinetics study of trazodone after iv, ip and po administration has been performed in rats. Trazodone was given to animals in a single or multiple doses of 20 mg/kg p. o. or ip, or in doses of 5 and 10 mg/kg iv. The levels of the drug in plasma and brain tissue were assayed spectrofluorometrically at predetermined time intervals. The results indicate that neither the route of administration nor the dosage schedule affects in significant manner the pharmacokinetics of trazodone, but the pharmacokinetic parameters depend upon the dose used. The affinity of the drug to blood and brain tissue is nearly the same, in contrast to imipramine which shows, a low affinity to blood and high affinity to brain tissue.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.

D014018	Tissue Distribution	Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.	Distribution, Tissue,Distributions, Tissue,Tissue Distributions
D014196	Trazodone	A serotonin uptake inhibitor that is used as an antidepressive agent. It has been shown to be effective in patients with major depressive disorders and other subsets of depressive disorders. It is generally more useful in depressive disorders associated with insomnia and anxiety. This drug does not aggravate psychotic symptoms in patients with schizophrenia or schizoaffective disorders.
