Potential Drug Targets
In the treatment of epilepsy, drugs targeting both GABA transporters and the GABA metabolizing enzyme GABA-transaminase (vigabatrin) have been marketed, providing proof of principle for the neurotransmitter cycling systems as pharmacological targets. However, with regard to glutamate transport and metabolism no such drugs have been developed This is because glutamatergic synapses are abundant and the neurotransmitter glutamate is an important metabolite in metabolism, making interference capable of adverse effects. So far, most of the drug development directed at the glutamatergic system seems to have been focused on ionotropic glutamate receptors as pharmacological targets, although G-protein coupled receptors have been attracting increased attention over the years.

Famous quotes containing the words potential and/or drug:
“Much of what contrives to create critical moments in parenting stems from a fundamental misunderstanding as to what the child is capable of at any given age. If a parent misjudges a child’s limitations as well as his own abilities, the potential exists for unreasonable expectations, frustration, disappointment and an unrealistic belief that what the child really needs is to be punished.”
—Lawrence Balter (20th century)
“While man can still his body keep
Wine or love drug him to sleep,
Waking he thanks the Lord that he
Has body and its stupidity....”
—William Butler Yeats (1865–1939)
