ketamine party drug can cure depression within hours

LONDON: Ketamine, abused as the party drug "Special K", can provide immediate relief to chronically depressed and treatment-resistant patients, researchers have claimed.

Scientists at the Yale University have found evidence that the pediatric anesthetic helps regenerate synaptic connections between brain cells damaged by stress and depression.

They said ketamine works on an entirely different type of neurotransmitter system than current antidepressants, which can take months to improve symptoms of depression and do not work at all for one out of every three patients.

Understanding how ketamine works on the brain could lead to the development of an entirely new class of antidepressants, offering relief for tens of millions of people suffering from chronic depression.

"The rapid therapeutic response of ketamine in treatment-resistant patients is the biggest breakthrough in depression research in a half century," said Ronald Duman.

Duman and George K Aghajanian, also professor of psychiatry at Yale, suggest that ketamine works is crucial because of the drug's limitations.

The improvement in symptoms, which are evident just hours after ketamine is administered, lasts only a week to 10 days.

In large doses, ketamine can cause short-term symptoms of psychosis and is abused as the party drug "Special K".

In their research, Duman and others show that in a series of steps ketamine triggers release of neurotransmitter glutamate, which in turn stimulates growth of synapses.

Research at Yale has shown that damage of these synaptic connections caused by chronic stress is rapidly reversed by a single dose of ketamine.

Efforts to develop drugs that replicate the effects of ketamine have produced some promising results, but they do not act as quickly as ketamine.

Researchers are investigating alternatives they hope can duplicate the efficacy and rapid response of ketamine.
