Class (Stereo):
CHEMICAL (RACEMIC)
Conditions:
Vigabatrin is an anticonvulsant chemically unrelated to other anticonvulsants. Vigabatrin prevents the catabolism of GABA by irreversibly inhibiting the enzyme GABA transaminase. It is an analog of GABA, but it is not a receptor agonist. However, vigabatrin is not a potent inhibitor of GABA-T with a Ki of 10 mM. Vigabatrin increases brain concentrations of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the CNS, by irreversibly inhibiting enzymes that catabolize GABA (gamma-aminobutyric acid transaminase, GABA-T). Duration of action is determined by rate of GABA-T re-synthesis. Vigabatrin may also work by suppressing repetitive neuronal firing through inhibition of voltage-sensitive sodium channels. Although administered as a racemic mixture, only the S(+) enantiomer is pharmacologically active. Vigabatrin is sold under the trade name SABRIL, it is indicated as adjunctive therapy for adults and pediatric patients 10 years of age and older with refractory complex partial seizures who have inadequately responded to several alternative treatments and for whom the potential benefits outweigh the risk of vision loss.

VIGABATRIN, R-(-)- is an inactive enantiomer of gamma-vinyl-gamma-aminobutyric acid. Vigabatrin exists as a 50/50 racemic mixture of two enantiomers. It is an irreversible inhibitor of the GABA-transaminase, the enzyme responsible for the catabolism of GABA, thus increasing the GABAergic transmission. This drug is mainly prescribed for the treatment of West syndrome, a deleterious pediatric epileptic syndrome also known as infantile spasms. The maximum and minimum plasma concentrations of vigabatrin at steady-state were lower for the S(+) than for the R(-) enantiomer, while the apparent oral clearance was higher for the S(+) than for the R(-) enantiomer in a patient affected with tuberous sclerosis who developed major agitation and aggression and in whom impaired renal function was diagnosed. The question remains of the potential toxicity of the high levels of the R(-) enantiomer. The placental uptake of the active S(+)-isomer from the maternal circulation exceeded that of the R(-)-isomer and this was reflected by a corresponding difference in placental tissue concentrations.

Conditions:
2,5-Dimethyl-N-Phenyl-3H-diazaphophol-4-imine is a quinonoid tautomer of GABAA and GABAB agonist progabide. According to quantum mechanical calculations, a quinonoid form is predominant in polar solvents, while aromatic tautomer is prevalent in apolar solvents. Progabide is a prodrug of gamma-aminobutyric acid and was investigated for the treatment of epilepsy, Parkinson's disease, schizophrenia, clinical depression, anxiety disorder, and other diseases. Progabide was marketed in France by Sanofi Aventis under tradename Gabrene for use in monotherapy and also as adjunctive therapy for generalized tonic-clonic, myoclonic, partial seizures, and for Lennox‐Gastaut syndrome, in both children and adults.

Conditions:
Cosyntropin (ACTH (1–24)) is a synthetic peptide that is identical to the 24-amino acid segment at the N-terminal of adrenocorticotropic hormone. It is intended for use as a diagnostic agent in the screening of patients presumed to have adrenocortical insufficiency. Cosyntropin may bind to sites located on the adrenergic nerve endings associated with the cardiac tissue, and such binding would interfere with the neuronal reuptake of the catecholamines
