PHENMETRAZINE

  • [PRELUDIN]

DEA CODE 1631: Schedule 2

Phenmetrazine is an anti-obesity drug, which was discovered by Boehringer-Ingelheim in 1952 and approved by FDA under the name Preludin. Later on the drug was withdrawn from the market due to the reported cases of abuse. According to some studies, misuse of phenmetrazine turned many young addicts to crime. It is suggested that the drug exerts its effect by inhibiting the monoamine transport.

Preludin tablets, also known as Prellies:
The active ingredient in Prellies is phenmetrazine, a stimulant drug that is now illegal all over the world. It was patented in 1952 by German pharmaceutical firm Boehringer Ingelheim and came to market in 1956, but was banned internationally fifteen years later.

Phenmetrazine was incredibly popular in its day, taken, biographers claim, by John F. Kennedy, Elvis Presley, Frank Sinatra, Tennessee Williams, Truman Capote, and Marilyn Monroe, among others. It was sold all over the U.S. and Europe in the 1960s, as an anorectic - a diet aid, since it controls appetite. It also produces a euphoric rush by hitting the brain's dopamine pleasure and reward centers, just as good food with friends, a gambling win, and sex do. But phenmetrazine - like cocaine, amphetamines and other stimulants - hits those pleasure centers harder and longer.

Phenmetrazine was no different from most of the synthetics used in the 1960s: legitimate prescription drugs that were diverted into the hands of users looking for a kick. But with the consumption of drugs so prevalent following the 1960s psychedelic and counter cultural explosion, the authorities felt the need to act.

The Beatles:
Left Liverpool for Hamburg in August of 1960. By the end of the 39 weeks they played there on four trips from 1960 to December 1962, Beatles biographer Mark Lewisohn estimates, the band played about 1,110 hours. On one trip to Germany, the band played 415 hours in 14 weeks.

That's a dream job for a bunch of teenagers. But it was still hard: The early Beatles' shows were raucous, and they didn't like to repeat themselves on stage. Lewisohn's new book - Tune In, an engaging, detailed narrative of the Beatles from before birth to the eve of their big break in 1963 - offers revelations as to what helped the band with this exhaustive work schedule: prellies, an upper that has since been removed from the market.

Officially known as phenmetrazine and sold under the name Predulin, the drug was popular in Europe in the late 1950s and early 1960s. Prellies were especially easy to obtain in Hamburg's red light district, St. Pauli. Sold as a diet pill, prellies became the drug of choice for the Beatles and other bands looking to stay sharp and awake. Tony Sheridan - whose "My Bonnie (https://www.youtube.com/watch?v=pBhqy07_KWw)" features the Beatles as a backing band, the group's first recording - helped introduce the Beatles to the drug in 1961, during their second trip to Hamburg. "Here's something to keep you awake," he reportedly told the group (http://www.beatlesbible.com/features/drugs/).

This wasn't like the more famous Beatles experiments with drugs later in the 1960s. For the Beatles, the prellies were more performance enhancing. The Hamburg scene in the early 1960s, drugs and all, is what turned an unknown group of teenagers into The Beatles. Speed kills, but it also helped produce the greatest band in the world.

To help bring about & maintain loss of wt the patient must be taught to curtail overeating & to consume a suitable diet.

SWGDRUG Phenmetrazine Monograph

A stimulant drug that was previously used as an appetite suppressant, but has since been withdrawn from the market. The drug had been widely abused. It was initially replaced by its analogue phendimetrazine (under the brand name Prelu-2) which functions as a prodrug to phenmetrazine, but now it is rarely prescribed, due to concerns of abuse and addiction.

In clinical use:
Phenmetrazine produces less nervousness, hyperexcitability, euphoria and insomnia than drugs of the amphetamine family. It tends not to increase heart rate as much as other stimulants. Due to the relative lack of side effects, one study found it well tolerated in children. In a study of the effectiveness on weight loss between phenmetrazine and dextroamphetamine, phenmetrazine was found to be slightly more effective.

Recreational Use:
Phenmetrazine has been used recreationally in many countries, including Sweden. When stimulant use first became prevalent in Sweden in the 1950s, phenmetrazine was preferred to amphetamine and methamphetamine by users. Eventually amphetamine became the dominant stimulant of abuse because of its greater availability. Preludin was also used recreationally in the US throughout the 1960s and early 1970s. It could be crushed up in water, heated and injected. The street name for the drug in Washington, DC was "Bam". Phenmetrazine continues to be used and abused around the world, in countries including South Korea.

Jack Ruby said he was on phenmetrazine at the time he killed Lee Harvey Oswald.

  
Phendimetrazine Tartrate - Some of the drug is metabolized to phenmetrazine and also phendimetrazine-N-oxide. The average half-life of elimination is about 3.7 hours for both the extended-release and immediate release forms.
