Abstract:
1. Bupropion (12.5-75 mg kg-1) was given intraperitoneally to rats and was found to decrease the food consumption of the animals dose-dependently. While phenoxybenzamine, propranolol and methergoline failed to antagonize the anorectic effect of the drug; pimozide a dopamine receptor blocker decreased anorexia induced by bupropion. 2. Bupropion (12.5-50 mg kg-1) also caused a marked increase in locomotor activity of the rats. The increase in locomotion produced by bupropion was completely antagonized by pretreatment of the animals with pimozide and reserpine plus a-methyl-p-tyrosine, but not by pretreatment with phenoxybenzamine, propranolol or methergoline. 3. Taking into considerations the evidences of dopaminergic properties of bupropion shown by the others, it could be suggested that the anorexia and hyperactivity produced by bupropion may be induced through the indirect dopaminergic mechanism.

One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral bioavailability, and...

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
