The opiod painkiller propoxyphene has been generally used in the U. S. since it gained FDA approval in 1957 under the brand Darvon.

Eli Lilly & Company, the drug’s maker at the time, capitalized on the opening that then existed between comparatively puny painkillers like Aspirin and strong, highly-addictive drugs like morphine.

Darvon was therefore hailed as a development in discomfort management and, building on its success, Eli Lilly and company compounded Darvocet ( propoxyphene together with acetaminophen ), which gained FDA approval in 1972. In the 3 years following Darvocet’s introduction, propoxyphene stayed highly regarded, with Darvon averaging virtually 40,000,000 prescriptions a year between 1973 and 1975. But new studies that concluded propoxyphene was no better as a painkiller than 2 aspirin and reports linking the drug to the end of 589 USA citizens led many to begin querying its overall benefits. The buyer advocacy group Public Voter called propoxyphene the most lethal prescription drug in the United States, and cited its link to thousands of fatalities and overdoses in petitioning the Office of Health, Education and Welfare ( the group that that was then accountable for the oversight of controlled pharmaceuticals ) to prohibit the drug in 1978, a request that was denied the following year. Public Voter replenished its attack on propoxyphene with a second petition, this time filed with the FDA, to ban propoxyphene products in 2006. The group’s effort was rebuffed once more, but this time it replied to beat by suing the FDA in 2008 over its refusal to get rid of from the market a substance that, according to Public Voter , was linked to 2110 accidental deaths between 1981 and 1999. The lawsuit put a little pressure onto the FDA, which deferred the destiny of propoxyphene to an independent advisory panel. The panel voted 14-12 for the drug’s market withdrawal, but the FDA overruled its call, saying that further proof was required, especially concerning propoxyphene’s effects on the heart, to basically change its benefit / risk profile ( that the agency uses to figure out the overall safety of a product ). The FDA needed Xanodyne Pharmaceuticals, Inc, which lately had taken possession of the Darvon and Darvocet brands from Eli Lilly & Company, to do research into the effect of propoxyphene on the heart. The results, which proved that the drug causes disturbances in coronary electric activity even at prescribed doses in healthy patients, sealed the substance’s destiny, as the FDA just after requested that all kinds of propoxyphene be removed from the U.S.


It took less than 3 weeks from the time of the FDA’s call for the 1st legal action to be filed against Xanodyne and in the approaching weeks and months, many more propoxyphene court actions are anticipated. The proof presented over time to the FDA pointing to the drug’s potential to cause heart issues and random overdose death will probably now be used as evidence that drug makers should have fairly known about, but did not provide adequate alert of, the agony reliever’s risks.

If you or a friend experienced health issues that you think were related to the utilisation of propoxyphene, particularly a stroke or coronary accompanied by Darvon side-effects like arrhythmia, atrial fibrillation, or an unstable pulse, you must debate your potential claim with a professional lawyer. Quality legal help provides you with the very best possibility of holding a pharmaceutical manufacturer accountable for the discomfort, suffering, and monetary losses you sustained thanks to the use of Darvon, Darvocet, or a universal type of propoxyphene.
