Identification
- Generic Name
- 8-chlorotheophylline
- DrugBank Accession Number
- DB14132
- Background
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 1,2. Because adenosine causes a decrease in neuronal firing, blockade of the adenosine receptor causes the reverse effect resulting in excitation.

Drug Interaction Integrate drug-drug
interactions in your software1,2-Benzodiazepine The therapeutic efficacy of 1,2-Benzodiazepine can be decreased when used in combination with 8-chlorotheophylline. Abametapir The serum concentration of 8-chlorotheophylline can be increased when it is combined with Abametapir. Abatacept The metabolism of 8-chlorotheophylline can be increased when combined with Abatacept. Abiraterone The serum concentration of 8-chlorotheophylline can be increased when it is combined with Abiraterone. Acebutolol The risk or severity of adverse effects can be increased when Acebutolol is combined with 8-chlorotheophylline. Acenocoumarol The metabolism of 8-chlorotheophylline can be decreased when combined with Acenocoumarol. Acetaminophen The metabolism of 8-chlorotheophylline can be decreased when combined with Acetaminophen. Acetazolamide Acetazolamide may increase the excretion rate of 8-chlorotheophylline which could result in a lower serum level and potentially a reduction in efficacy. Acyclovir The metabolism of 8-chlorotheophylline can be decreased when combined with Acyclovir. Adalimumab The serum concentration of 8-chlorotheophylline can be decreased when it is combined with Adalimumab.
