Cinnarizine's antagonistic effects of D2 dopamine receptors in the striatum leads to symptoms of depression, tremor, muscle rigidity, tardive dyskinesia, and akathisia. 17 of 100 new parkinsonism cases are linked to administration of either cinnarizine or flunarizine. [5] Drug induced parkinsonism is the second leading cause of parkinsonism. [22]
"Treatment of vertigo due to acute unilateral vestibular loss with a fixed combination of cinnarizine and dimenhydrinate: a double-blind, randomized, parallel-group clinical study". Clin Ther . 26 (6): 866– 77.
Symptoms of varying BAC levels. Additional symptoms may occur. The short-term effects of alcohol consumption range from a decrease in anxiety and motor skills and euphoria at lower doses to intoxication (drunkenness), to stupor, unconsciousness, anterograde amnesia (memory "blackouts"), and central nervous system depression at higher doses.
As the article states, cinnarizine is a CNS depressant, that is, it has antihistaminic, antiserotonergic, antidopaminergic effects. How strong, you ask? Strong enough not to be approved. One example: the usual dosage is supposed to be 2-3 tablets a day. Here I will describe effects on a test subject at a dose of 2 tablets a day.
Flunarizine is a selective calcium antagonist with moderate other actions including antihistamine, serotonin receptor blocking and dopamine D 2 blocking activity. Compared to other calcium channel blockers such as dihydropyridine derivatives, verapamil and diltiazem, flunarizine has low affinity to voltage-dependent calcium channels.
[52] [53] In rats, less than 2% of the drug is excreted unchanged. [53] The time to reach maximum concentration (T max) of hydroxyzine is about 2.0 hours in both adults and children and its elimination half-life is around 20.0 hours in adults (mean age 29.3 years) and 7.1 hours in children.
Antihistamines are drugs which treat allergic rhinitis, common cold, influenza, and other allergies. [1] Typically, people take antihistamines as an inexpensive, generic (not patented) drug that can be bought without a prescription and provides relief from nasal congestion, sneezing, or hives caused by pollen, dust mites, or animal allergy with few side effects.

The pharmacokinetics of cetirizine have been found to increase linearly with dose across a range of 5 to 60 mg. [9] Its C max following a single dose has been found to be 257 ng/mL for 10 mg and 580 ng/mL for 20 mg. [8] Food has no effect on the bioavailability of cetirizine but has been found to delay the T max by 1.7 hours (i.e., to ...
