ACTIONS AND CLINICAL PHARMACOLOGY
Methotrimeprazine possesses antipsychotic, tranquilizing, anxiolytic,
sedative and analgesic properties and
it is also a potent potentiator of anesthetics.
Methotrimeprazine possesses strong sedative properties. It potentiates
ether and hexobarbital anesthesia as
well as morphine analgesia. It also exerts a potent anti-apomorphine
effect, a hypothermic action 3 times
more potent than that of chlorpromazine and strong antispasmodic and
anti-histaminic effects.
Methotrimeprazine is capable of reversing epinephrine-induced
hypertension but has practically no effect
against norepinephrine and acetylcholine. It readily protects rats
against traumatic shock and produces
deep local anesthesia following parasciatic injections.
Comparative Bioavailability
A comparative bioavailability study was performed using healthy human
volunteers. The rate and extent of
absorption of methotrimeprazine were measured and compared following a
single oral 25 mg dose of
METHOPRAZINE or Nozinan. The results from measured data are summarized
as follows:
