Pentoxifylline for Cocaine Use
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests how a drug called pentoxifylline affects the experience of using cocaine. Researchers aim to determine if pentoxifylline can alter cocaine's effects in regular users. Participants will join one of three groups: two will receive different doses of pentoxifylline, and one will receive a placebo (a pill with no active drug). Ideal candidates for this trial have recently used cocaine, meet the diagnostic criteria for cocaine use disorder (CUD), and are not currently seeking treatment for drug use. As an Early Phase 1 trial, this research focuses on understanding how pentoxifylline works in people, offering participants a chance to contribute to groundbreaking research.
Will I have to stop taking my current medications?
The trial information does not specify if you need to stop taking your current medications. However, if you are taking medications that lower the seizure threshold, you may not be eligible to participate.
Is there any evidence suggesting that pentoxifylline is likely to be safe for humans?
Research has shown that pentoxifylline is generally safe and has been used for other health issues. This medication often improves blood flow in people with circulation problems. Although pentoxifylline has not been proven to treat cocaine use disorder, its safety is well-known.
In other cases, patients usually tolerate pentoxifylline well. Common side effects might include dizziness, headache, or nausea, but serious side effects are rare. Since this is an early trial, the main focus will be on the drug's safety for people who use cocaine. While testing for cocaine use is just beginning, there is already some understanding of its safety from other uses.12345Why do researchers think this study treatment might be promising for cocaine use?
Researchers are excited about pentoxifylline as a treatment for cocaine use because it offers a new approach by potentially reducing inflammation and improving blood flow in the brain, which could help in managing addiction. Unlike current treatments like behavioral therapies and medications such as disulfiram or modafinil, pentoxifylline targets the vascular system, which is a novel angle for addressing cocaine addiction. Additionally, the study explores two different dosages, 1200 mg and 1600 mg, which could provide insights into optimizing its effectiveness and safety.
What evidence suggests that pentoxifylline might be an effective treatment for cocaine use?
Research suggests that pentoxifylline might help reduce cocaine use and cravings. Some studies have shown a noticeable decrease in cocaine use among people taking pentoxifylline, although these results were not always statistically significant. While the evidence isn't definitive, a trend indicates that pentoxifylline could assist those struggling with cocaine addiction. Participants in this trial will receive either a daily dose of pentoxifylline at 1200 mg, a higher dose at 1600 mg, or a placebo. Researchers believe pentoxifylline works by improving blood flow, which might help lessen the desire for cocaine. However, more research is needed to fully understand its effectiveness.12467

Trial Overview
The study tests how pentoxifylline affects the body's response to cocaine. It includes people given IV cocaine, others receiving pentoxifylline (an anti-inflammatory medication), and some getting a placebo. The goal is to see if pentoxifylline can reduce the effects of cocaine as part of the HEAL Initiative.
