Preparation Note
Trazodone hydrochloride dissolves in methanol at 25 mg/ml to yield a clear, colorless solution. It also dissolves in water at 50 mg/ml, with heating to yield a hazy colorless solution. Furthermore, the product is soluble in DMSO or in 0.1 N HCl (7.4 mg/ml). The solubility in a 45% (w/v) aqueous 2-hydroxpropyl-β-cyclodextrin is 23.3 mg/ml. However, it is practically insoluble in other common organic solvents. For HPLC test, the product can be dissolved at 0.25 mg/ml in 50:50 water:methanol (v/v), as this gives better results of dissolution and peak shape than using the product as a 1 mg/ml solution in water.

The psychopharmacology of depression is a field that has evolved rapidly in just under 5 decades. Early antidepressant medications--tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs)--were discovered through astute clinical observations. These first-generation medications were effective because they enhanced serotonergic

The effects of the antidepressant drug, trazodone, on the extracellular 5-hydroxytryptamine (5-HT) levels in the frontal cortex of freely moving rats was investigated using microdialysis coupled to a high performance liquid chromatography (HPLC) detection method. Systemic administration of 1.25 and

The effects of trazodone on the cyclic GMP elevation elicited by N-methyl-D-aspartate in rat cerebellar slices were analyzed. Trazodone inhibited in a concentration-dependent manner (EC50 = 0.82 nM) the cyclic GMP response evoked by 0.1 microM N-methyl-D-aspartate. The inhibition was

Many animals, especially those that develop externally, are equipped with innate color preferences that promote survival. For example, Xenopus tadpoles are known to phototax most robustly towards mid-spectrum ("green") wavelengths of light while avoiding shorter ("blue") wavelengths. The innate preference
