Piprinhydrinate is compositon of Diphenylpyraline and 8-chloroteophylline. 8-Chlorotheophylline is a stimulant drug of the xanthine chemical class, with physiological effects similar to caffeine. Diphenylpyraline is an antihistamine that prevents, but does not reverse, responses mediated by histamine alone. Diphenylpyraline antagonizes most of the pharmacological effects of histamine, including urticaria and pruritus. Also, diphenylpyraline may exhibit anticholinergic actions (as do most of the antihistamines) and may thus provide a drying effect on the nasal mucosa. 8-Chlorotheophylline main use is in combination with Diphenylpyraline or diphenhydramine in the antiemetic Piprinhydrinate and dimenhydrinate. Diphenylpyraline (or diphenhydramine) reduces nausea but causes drowsiness, and the stimulant properties of 8-Chlorotheophylline help ward off that side-effect.

In Vitro Use Guide
Brain tissue was obtained at autopsy on 18 Japanese patients with chronic schizophrenia. The brain tissues were weighed, homogenized and centrifuged. The specific 3H-mepyramine binding to the brain tissues reached equilibrium values within 20 min after incubation at 25°C. Inhibition of the specific component of the 3H-mepyramine binding by Diphenylpyraline was then studied. The H1 antagonist diphenylpyraline (Ki=4.1nM) was potent competitors for the specific binding of 3H-mepyramine.
