INJECTABLE ATARACTIC TRANQUILIZER
Bottle x 10 and 50 ml
Formula:
Acepromazine Maleate 1 g.; Excipient q.s. 100 ml.
Indications:
Generally indicated as pre-anesthetic medication, being a potent neuroleptic agent. As an aid in the
control of unruly animals and/or those presenting trauma at the time of clinical examination (e.g.: fractures, burns,
etc.) that make examination difficult. It can also be used prior to transport and/or loading. It is useful when used together
with other local or general anesthetics for various procedures or treatments (castration, neurectomies,
skin tumor removal, ocular surgeries, shoeing-related problems, etc). In Horses it can be used as an
adjunct treatment for laminitis (developmental phase) and in cases of colic to restore intestinal transit.

Contraindications and limitations of use:
Acepromazine has adrenolytic actions by blocking alpha receptors, thus reversing the pressor effect of adrenaline, which then acts only on
beta receptors. Therefore, adrenaline should not be used as a pressor amine; noradrenaline or phenylephrine should be used instead, as they act only on alpha receptors. In animals with liver disease it is advisable to use with caution, as
the ACEPROMAZINA HAMPTON component is metabolized in the liver. It may cause minor cardiac arrhythmias. In animals with
a history of cardiac disorders it is advisable to use with caution. In animals with heart disease it may worsen the condition, so
caution is advised, as well as in geriatric animals. When given intravenously, inject slowly. In epileptic animals it may cause seizures.
Its use is not recommended. Like all phenothiazine derivatives it potentiates the sensitivity to organophosphate compounds and to procaine hydrochloride.
For this reason, simultaneous use with these should be avoided. Occasionally, adult breeding males may suffer irreversible penile prolapse, which
must be manually reduced.
