Chemistry
Triamcinolone acetonide, also known as 9α-fluoro-16α-hydroxyprednisolone 16α,17α-acetonide or as 9α-fluoro-11β,16α-17α,21-tetrahydroxypregna-1,4-diene-3,20-dione cyclic 16,17-acetal with acetone, is a synthetic halogenated cyclic ketal pregnane corticosteroid. It is the C16α,17α acetonide of triamcinolone. Veterinary use
Triamcinolone acetonide is also used in veterinary medicine as an ingredient in topical ointments and in topical sprays for control of pruritus in dogs. A series of injections with triamcinolone acetonide or another corticosteroid may reduce keloid size and irritation. It is used as a preinductor and/or inductor of birth in cows. It was also used in the horse racing industry, but it is now a banned substance if found in a horses system on race day. See also

Priapism
A relatively rare side effect associated with trazodone is priapism, likely due to its antagonism at α-adrenergic receptors. More than 200 cases have been reported, and the manufacturer estimated that the incidence of any abnormal erectile function is about one in 6,000 male patients treated with trazodone. The risk for this side effect appears to be greatest during the first month of treatment at low dosages (i.e. <150 mg/day). Early recognition of any abnormal erectile function is important, including prolonged or inappropriate erections, and should prompt discontinuation of trazodone treatment. Spontaneous orgasms have also been reported with trazodone in men.Clinical reports have described trazodone-associated psychosexual side effects in women as well, including increased libido, priapism of the clitoris, and spontaneous orgasms. Others
Rare cases of liver toxicity have been observed, possibly due to the formation of reactive metabolites.Elevated prolactin concentrations have been observed in people taking trazodone. They appear to be increased by around 1.5- to 2-fold.Studies on trazodone and cognitive function are mixed, with some finding improvement, others finding no change, and some finding impairment.Trazodone does not seem to worsen periodic limb movements during sleep.Trazodone is associated with increased risk of falls in older adults. It has also been associated with increased risk of hip fractures in older adults. Pregnancy and lactation
Sufficient data in humans are lacking. Use should be justified by the severity of the condition to be treated. Overdose
There are reported cases of high doses of trazodone precipitating serotonin syndrome.
