Cinnarizine is an antihistamine and calcium channel blocker of the diphenylmethylpiperazine group. [5] It is prescribed for nausea and vomiting due to motion sickness [6] or other sources such as chemotherapy, [7] vertigo, [8] or Ménière's disease. [9] Cinnarizine is one of the leading causes of drug-induced parkinsonism. [5]

The research which does exist is mostly short-term studies or studies which look at too few people to make general assumptions. [1] Another gap in the research is in information reporting the health effects for individuals with long-term allergies who take antihistamines for a long period of time. [ 1 ]
Diphenhydramine is the primary constituent of dimenhydrinate and dictates the primary effect. The main differences relative to pure diphenhydramine are a lower potency due to being combined with 8-chlorotheophylline (by weight, dimenhydrinate is between 53% and 55.5% diphenhydramine) [10] and the fact that the stimulant properties of 8-chlorotheophylline help reduce the side ...
Because of this, it does not interact significantly with drugs that inhibit or induce cytochrome P450 enzymes such as theophylline, erythromycin, clarithromycin, cimetidine, or alcohol. [3] Studies with cetirizine synthesized with radioactive carbon-14 show that 90% of excreted cetirizine is unchanged at 2 hours, 80% at 10 hours, and 70% at 24 ...
