How Emer Oral Solution 20 mg/5 ml works

Emer Oral Solution 20 mg/5 ml acts on GABAA receptors, increasing synaptic inhibition. This has the effect of elevating seizure threshold and reducing the spread of seizure activity from a seizure focus. Emer Oral Solution 20 mg/5 ml may also inhibit calcium channels, resulting in a decrease in excitatory transmitter release. The sedative-hypnotic effects of phenobarbital are likely the result of its effect on the polysynaptic midbrain reticular formation, which controls CNS arousal.

Emer Oral Solution 20 mg/5 ml Alcohol interaction

[Major] GENERALLY AVOID:

Concurrent acute use of barbiturates and ethanol may result in additive CNS effects,

including impaired coordination, sedation, and death.

Tolerance of these agents may occur with chronic use.

The mechanism is related to inhibition of microsomal enzymes acutely and induction of hepatic microsomal enzymes chronically.

The combination of ethanol and barbiturates should be avoided.

Emer Oral Solution 20 mg/5 ml Hypertension interaction

[Major] The intravenous administration of barbiturates may produce severe cardiovascular reactions such as bradycardia, hypertension, or vasodilation with fall in blood pressure, particularly during rapid infusion.

Parenteral therapy with barbiturates should be administered cautiously in patients with hypertension, hypotension, or cardiac disease.

The intravenous administration of barbiturates should be reserved for emergency treatment of acute seizures or for anesthesia.
