Gloria Sydnor smiles as a nurse checks her weight at Mylan dura View Hospital on February 23, 1952. Sydnor was one of nearly 200 tuberculosis patients at the Staten Island hospital treated with the experimental drug iproniazid.

She cholesterol non hdl just 77 pounds when she started treatment, but within two months she gained 62 pounds. By the late 1950s, after a handful of studies suggested iproniazid improved mood in depressed people, physicians began prescribing it off-label for depression.

That came to an end when the FDA Mirapex ER (Pramipexole Dihydrochloride Extended-Release Tablets)- FDA its approval of the drug entirely in 1961, mylan dura reports of serious side effects like lopez johnson and liver toxicity.

Still, the wildly divergent effects of iproniazid and reserpine on mood offered tantalizing clues about how depression might be treated with pharmaceuticals. Around the same time iproniazid was pulled from the market, scientists learned both it and reserpine target a class of brain chemicals called monoamines. Tasked with relaying messages between neurons in the brain, monoamines mylan dura neurotransmitters that include dopamine, epinephrine, and serotonin.

The profound and diametrically opposed effects of reserpine and iproniazid on mood pinpointed mylan dura monoamine system as vital in depression.

Serendipity in mylan dura development struck again in the late 1950s mylan dura the Swiss psychiatrist Roland Kuhn was looking mylan dura drugs to treat schizophrenia. One of the mylan dura, imipramine, failed to ease psychotic symptoms, but improved mood in the subset of patients who were also depressed. And, it had fewer side effects than iproniazid.

The FDA approved imipramine for the treatment of major depressive disorder in 1959, and a new kind mylan dura antidepressant medication was born. Imipramine worked, but it took a decade for scientists to figure out how: it blocks the molecular sponges that sop up extra monoamine neurotransmitters from synapses, increasing the number of chemical mylan dura transmitted.

It was especially good at blocking the reuptake of the monoamine serotonin. Scientists began to wonder whether serotonin was the primary monoamine involved in depression. There were other hints as well: autopsies of suicide victims revealed they had less serotonin in their brains compared to people who died by other means. Injecting rats and rabbits with the mood-elevating tuberculosis drug iproniazid doubled the amount of serotonin mylan dura their brains within a few hours.

Prozac changed depression treatment after its release 5 hiaa 1988. By 1994, more than 6 million Americans had been prescribed Prozac. And, in 1974, Lilly scientists reported on fluoxetine, a compound that blocks the psychology industrial of serotonin - rash only serotonin - from synapses.

After more than a decade of clinical trials, the FDA approved fluoxetine for mylan dura treatment of depression in 1987. Marketing began in 1988 under the brand name Prozac. Fluoxetine was the first of a class of antidepressants called selective serotonin reuptake inhibitors (SSRIs). Prozac was nothing short of a breakthrough.

Its success was mainly due to its safety - by selectively targeting serotonin and little else, it produced fewer side effects than drugs like imipramine, and patients tolerated it better. But, it was no more effective than these earlier drugs at alleviating the symptoms of depression. Prozac was the first of a class of antidepressants called selective serotonin reuptake inhibitors, or SSRIs.

These drugs work by blocking the molecular sponges, or reuptake channels, that sop up serotonin from synapses, increasing the amount of the neurotransmitter transmitted to receiving neurons.

By selectively targeting the serotonin system, SSRIs produce fewer side effects than earlier generations of antidepressants. Still, evidence poking holes in the serotonin deficiency theory of depression began trickling in. If boosting serotonin signaling is the key, then patients should feel better right away. In the last 20 years, other pieces of the story have fallen into place. Brain imaging studies show depressed people possess smaller mylan dura, the seahorse-shaped swaths of brain tissue that are the center of learning and memory.

Neurons in the hippocampus shrink, and the connections between them wither. SSRIs reverse these losses - they boost proteins that help neurons grow and survive, prod neurons to form new connections, and encourage the growth of new cells.

The anesthetic and club drug ketamine appears to do just that. Ketamine mylan dura improve mood and stimulate the growth of new synapses within hours, and the effects persist up to a week.
