The thing is doctor, that my patient is using bdzs and i want to switch them... so i was wondering if melatonine is good as trazodone?

BDZ Tx: Neither is treatment for use of bdzs. Treatment usually involves taper, or use of Phenobarbital in supervised setting, depending on dose and length of treatment.

Not the same at all: Melatonin, trazodone, and benzodiazepines are 3 different things -- & neither melatonin nor trazodone can be used to "switch" from a benzodiazepine. Benzo needs to be tapered very gradually itself, or sleep disturbance and withdrawal could result. Melatonin is not specifically a sedating agent, but trazodone could be used in that way. Melatonin can help initiate sleep but not help stay asleep.
