Secbutabarbitale
Secbutabarbitale Uses, Dosage, Side Effects, Food Interaction and all others data.
Secbutabarbitale, or Butisol, is a fast onset barbiturate with short duration of action compared to other barbiturates. This makes butabarbital a useful drug for treating severe insomnia and pre-operative anxiety. Secbutabarbitale is less commonly used in recent years, as more patients are typically prescribed benzodiazepines. Its short duration of action gives butabarbital a high abuse potential, comparable to secobarbital.
Secbutabarbitale was granted FDA approval on 5 June 1939.
Secbutabarbitale potentiates GABAergic neurons while inhibiting neuronal acetylcholine and glutamate receptors to produce sedation. Secbutabarbitale is an intermediate acting barbiturate with a duration of action of approximately 6-8 hours. The therapeutic index is quite wide as doses vary considerably from patient to patient. Patients should be counselled regarding the risk of worsening insomnia, drowsiness, falls, and complex behaviour while not fully awake.

Uses
Secbutabarbitale is a barbiturate drug used as a sedative and hypnotic.
Secbutabarbitale is indicated for use as a sedative or hypnotic. Secbutabarbitale should not be used to treat insomnia for longer than 2 weeks.
Secbutabarbitale is also used to associated treatment for these conditions: Insomnia
How Secbutabarbitale works
Barbiturates like butabarbital potentiate GABA-A receptors and inhibit receptors for neuronal acetylcholine, and kainate. GABA-A receptors are predominantly on the post-synaptic membrane, and upon activation, open chloride channels to hyperpolarize the neuron and decreased firing rate. Potentiation of GABAergic neurons produces sedation. Inhibition of neuronal acetylcholine receptors and glutamate receptors of the kainate subtype desensitize their respective neurons, producing sedation.
Toxicity
Patients experiencing an overdose may present with unsteady gait, slurred speech, nystagmus, confusion, poor judgement, irritability, and insomnia. Acute overdoses may present as CNS depression, respiratory depression, oligouria, tachycardia, hypotension, low body temperature, coma, and shock. An extreme overdose can lead to a flat EEG, resembling death, that is reversible provided there is no hypoxic brain damage. Overdose can be treated with symptomatic and supportive treatment.
Food Interaction
- Avoid alcohol. Concomitant use of alcohol and barbiturates may lead to increased.
Secbutabarbitale 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.

Major: acute alcohol intoxication, drug dependence, liver disease, porphyria, rash, respiratory depressionModerate: adrenal insufficiency, depression, hematologic toxicity, osteomalacia, paradoxical reactions
Half Life
Secbutabarbitale has a half life of 100 hours but its duration of action is only 6-8 hours.
Elimination Route
Barbiturates such as butabarbital are predominantly eliminated in the urine. In dogs, 3-5% of the dose is eliminated in the urine as the unchanged parent compound.
