Abstract:
The Expert Panel for Cosmetic Ingredient Safety (Panel) assessed the safety of three methylxanthines, Caffeine, Theobromine, and Theophylline, as used in cosmetics. All of these ingredients are reported to function as skin-conditioning agents in cosmetic products. The Panel reviewed the data relevant to the safety of these ingredients and concluded that Caffeine, Theobromine, and Theophylline are safe in cosmetics in the present practices of use and concentration described in this safety assessment.

Antiasthma Drugs: Methylxanthines
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
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...
