Do different brands of Ketamine have different effects?
Pharmaceutical liquid Ketamine is sold under various trade names, notably Ketalar, Ketaset, and Ketamine 500. Different brands can have different effects. For instance, Ketalar contains the preservative benzthonium chloride, which is an anticholinergic agent that counteracts the effects of the brain neurotransmitter, acetylcholine. It has its own psychoactive effects separate from Ketamine, mainly “delerium” at higher doses. Ketamine 500 contains the potentially neurotoxic substance, chlorobutanol, which has displayed harmful effects in some animal experiments.
