The Generic name of this drug

Treatment Summary

Dextropropoxyphene is an opioid painkiller that was manufactured by Eli Lilly and Company. It was used to treat mild pain, as well as coughs. Due to the risk of overdose and deadly cardiac arrhythmias, it was removed from the market in many countries. Dextropropoxyphene is made up of two isomers, dextro- and levo-; only the dextro-isomer has any analgesic effect, while the levo-isomer only exhibits a mild cough-suppressing effect.

How Propoxyphene Hydrochloride Affects Patients

Propoxyphene is a synthetic drug similar to methadone that works as an opiate pain reliever. It helps to block pain signals so that the person taking it does not feel pain. Propoxyphene does not help with coughing or reducing fever.

How Propoxyphene Hydrochloride works in the body

Propoxyphene works by directly interacting with your body's opioid receptors. It primarily binds to OP3 receptors, which are responsible for modulating the activity of certain proteins. When these proteins are activated, they reduce the amount of substances like dopamine and acetylcholine that your body releases. They also reduce the activity of nociceptive neurons, which helps to reduce pain. Propoxyphene also works to hyperpolarize neurons, making them less likely to fire and reducing nerve excitability.

Propoxyphene Hydrochloride for Pain

This medication is effective most of the time, but I have to take more of it in winter. If I do anything that's even a little bit more strenuous than walking, I have to take the full prescribed amount.

Propoxyphene Hydrochloride for Pain

I've been using this medication for 20 years after my skull was crushed and it's really helped me live a normal life despite my injuries. I'm now 68 and the government is trying to take it off the market, which would be devastating for me. It's hard enough to find a place that will fill my prescription as it is.

Propoxyphene Hydrochloride for Pain

Propoxphene was the only pill that worked for me. Unfortunately, some people died from mixing it with alcohol, so now the FDA has banned it. I'm in a lot of pain from two back surgeries and arthritis, and this was the only thing that helped.

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Why was propoxyphene removed from the market?

Answered by AI

Is Tylenol a propoxyphene?

"What is acetaminophen and propoxyphene?

Acetaminophen and propoxyphene are a combination of drugs that are used to relieve pain and reduce fever. These drugs were withdrawn from the U.S. market in November 2010."

It is sold under various names as a single-ingredient product (e.g., Darvon) and as part of a combination product with acetaminophen (e.g., Darvocet). The use of propoxyphene has declined since 2010 due to concerns about its effectiveness and potential for abuse and overdose."

Answered by AI

Why did they pull Darvocet off the market?

"The FDA has announced that the painkiller propoxyphene is being taken off the market as it has been linked to a potentially fatal heart-rhythm abnormality, even at recommended doses."

SBS-147 Safety Study

18 - 55
All Sexes
Cypress, CA

This study is part of the HEAL Initiative supported by the NIH. The purpose of this study is to learn how safe the study drug, SBS-147, is and how people's bodies respond to and process it. Researchers will also look for any side effects that may occur when taking SBS-147. Some participants will receive SBS-147, and others will receive a placebo, which looks the same but does not contain any medicine. This helps researchers fairly compare results. The study includes two parts: Single-Dose Group, where Participants receive SBS-147 or placebo one time. Multiple-Dose Group, where Participants receive SBS-147 or placebo once or twice daily for 7 days.

Guided Imagery Therapy for Abdominal Pain

7 - 12
All Sexes
Austin, TX

Chronic abdominal pain is common among children, and the majority of cases are attributed to functional abdominal pain disorders. One approach to treating these disorders is by using psychological therapies. This clinical trial aims to see how well pre-recorded guided imagery therapy sessions help children's abdominal pain when delivered via a mobile application (app) on a smartphone or tablet. Participants will complete a baseline abdominal pain and stooling diary to determine eligibility, as well as other surveys. Eligible participants will be given access to the guided imagery therapy mobile application. This intervention asks participants to listen to a 10- to 15-minute GIT session 5 out of 7 days per week for 8 weeks, in addition to their usual care for their abdominal pain. Then, participants will complete another abdominal pain and stooling diary, along with other psychometric surveys, at the end of this intervention period. Participants will also collect another diary and surveys 3 months post-treatment.
