Overview
8-Chlorotheophylline is a stimulant drug of the xanthine chemical class, with physiological effects similar to caffeine. Its main use is in combination with Diphenhydramine as the antiemetic drug Dimenhydrinate. The stimulant properties of 8-chlorotheophylline are thought to ward off the drowsiness caused by diphenhydramine's anti-histamine activity in the central nervous system. 8-chlorotheophylline produces a number of effects including nervousness, restlessness, insomnia, headache, and nausea, which are primarily attributed to its ability to block the adenosine receptor . Because adenosine causes a decrease in neuronal firing, blockade of the adenosine receptor causes the reverse effect resulting in excitation.
Indication
When used in combination with Diphenhydramine as the antiemetic Dimenhydrinate, 8-chlorotheophylline is indicated for the prevention and treatment of nausea, vomiting, or vertigo of motion sickness.
