Effectiveness

How Phenylbutazone Affects Patients

Phenylbutazone is a synthetic drug used to treat inflammatory conditions. It works by reducing the production of two types of molecules (prostaglandin H and prostacyclin) that can cause constriction of blood vessels, clotting of blood (platelet aggregation), and pain in the body.

How Phenylbutazone works in the body

Phenylbutazone works by blocking the production of proteins that cause inflammation. This reduces inflammation in the affected area.

Patient Q&A Section about phenylbutazone

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

Is phenylbutazone the same as Bute?

"Phenylbutazone, also known as "bute", is an NSAID that can be used to short-term treat pain and fever in animals."

Answered by AI

What is use of phenylbutazone?

"Phenylbutazone was introduced in the early 1950s to treat arthritis and other inflammatory musculoskeletal disorders in humans, and was soon widely used to treat animals, especially horses, suffering from pain and stiffness."

Answered by AI

What does phenylbutazone do to humans?

"Phenylbutazone can cause blood disorders like aplastic anemia, which causes the bone marrow to stop producing enough red and white blood cells and platelets. People with severe forms of the disease are at risk of life-threatening infections or bleeding."

Answered by AI

Can humans have phenylbutazone?

"Phenylbutazone is a nonsteroidal anti-inflammatory drug that used to be prescribed for the treatment of arthritic conditions, but it is no longer available for use in humans because of its numerous side effects, including aplastic anemia."

Lidocaine Injection vs Saline for Pain Management

18+
Female
Bay Shore, NY

We are doing this study to find the best way to manage pain during a procedure called urethral bulking. This procedure treats urine leakage that happens with coughing, laughing, sneezing, or physical activity. It works by injecting a gel-like substance around the urethra (the tube that urine comes out of) to help it stay closed when it should. We use a numbing gel (called lidocaine jelly) inside the urethra to help with pain during the procedure. In this study, we will also be administering lidocaine (numbing medication) injected around the urethra or a saline placebo (medical grade saltwater) injection, which has no numbing effect. A placebo is something that looks like a real treatment but doesn't have any medical effect. Both the lidocaine and the saline would be injected around the urethra using a small needle, and we'll compare how well they work at reducing pain.

Tranexamic Acid for Anterior Cruciate Ligament Injury

14 - 25
All Sexes
Skokie, IL

The goal of this clinical trial is to learn whether taking oral tranexamic acid (TXA) for one week after anterior cruciate ligament (ACL) reconstruction improves recovery in adolescents and young adults aged 14 to 25 years. All participants receive standard intravenous TXA during surgery. The main questions it aims to answer are: * Does oral TXA lower knee pain at 2 weeks after surgery? * Does oral TXA reduce the amount of opioid pain medicine used in the first 2 weeks? * Does oral TXA improve knee range of motion at 2 weeks? Researchers will compare oral TXA to a placebo (a look-alike capsule with no active drug) to see if oral TXA improves pain, opioid use, motion, strength, knee function, and return to sport. Participants will: * Take 3 capsules (oral TXA or placebo) once a day for the first 8 days after surgery (day of surgery through day 7) * Keep a home diary for 2 weeks recording pain scores, opioid pills taken and any side effects * Return for study visits at 2 weeks, 6 weeks, 12 weeks, 6 months, 9 months and 1 year for pain, motion, strength and function testing * Complete a survey at 2 years

Suzetrigine for Pain Management in Total Knee Replacement

18 - 80
All Sexes
New York, NY

Total knee replacements are among the most common and painful orthopedic procedures performed worldwide, often requiring intensive analgesia to support early ambulation and recovery. Despite widespread use of multimodal regimens, many patients still rely on opioids, which can cause sedation, nausea, constipation, and long-term dependency. Evaluating suzetrigine in this high-need population may improve recovery trajectories, reduce opioid consumption, and support enhanced recovery protocols. Given the growing surgical volume and the emphasis on opioid-sparing strategies, rigorous investigation of suzetrigine's efficacy in total knee replacement is of high clinical value. In this confirmatory (phase III) trial, patients undergoing primary total knee replacement will be randomized to receive either suzetrigine or placebo for 2 weeks (14 days), with the loading dose administered prior to surgery. The primary outcome is cumulative 48-hour opioid consumption in oral morphine equivalents starting from entry into the post-anesthesia care unit (PACU).

Fruit Juice for Inflammation

18 - 65
All Sexes
New York, NY

Dietary patterns and physical inactivity common in Western societies have been associated with chronic low-grade inflammation and an increased risk of non-communicable health conditions. Fruits and vegetables contain polyphenols and other bioactive compounds that may have antioxidant and anti-inflammatory properties and may influence inflammatory biomarkers. This study will evaluate the effects of increased consumption of a fruit juice on inflammatory biomarkers and exercise capacity in adults with mildly elevated inflammation. Approximately 40 participants will be randomly assigned to consume one of two fruit juice interventions daily for approximately 2 weeks. Changes in C-reactive protein (CRP) and exercise capacity, assessed using a 6-minute walk test, will be evaluated before and after the intervention and compared between the two groups.

All Sexes
Corpus Christi, TX

The goal of this pilot clinical trial is to learn whether auricular point acupressure (APA) can help reduce chronic musculoskeletal pain in adults age 50 and older who are living with HIV. The study will also examine whether APA is feasible, acceptable, and safe for this population. The main questions it aims to answer are: Does APA reduce chronic musculoskeletal pain and improve sleep and quality of life? Is APA feasible, acceptable, and safe for older people living with HIV? Researchers will compare true APA, in which small seeds are taped to specific ear points related to pain, with sham APA, in which seeds are taped to ear points not related to pain. The intervention will last 4 weeks. Participants will: Receive true APA or sham APA for 4 weeks Visit the study site weekly for placement of the ear seeds Press the ear seeds for 3 minutes, 3 times each day Complete daily surveys about pain and pain medication use Use a sleep monitor to track sleep Complete study assessments at the beginning and end of the intervention Complete an exit interview about their experience with APA

This is a Stage 1 study of a behavioral intervention, which means that a new intervention is being pilot tested to understand whether it is acceptable and feasible for people with advanced cancer to use. The purpose of this study is to evaluate whether a series of 3 10-minute videos may help improve prescription opioid pain management and opioid stigma for people living with advanced cancer. Approximately 45 participants will take part in this study at the University of Alabama at Birmingham. People who choose to participate in this study will complete a series of baseline questionnaires, and then will be randomized to one of two groups: 1) the group that gets the video intervention, or 2) the group that gets a written handout with information about cancer pain. About 4 weeks later, all participants will also be asked to fill out another series of questionnaires.

Genistein for Cardiovascular Health in HIV

18 - 80
All Sexes
London, Canada

People living with HIV (PLHIV) live longer because of modern HIV medicines, but even with these treatments, their bodies are more inflamed. Long term inflammation increases the risk of heart disease, chronic pain, lung disease, dementia, arthritis, and other infections. Because some anti-inflammatory medicines can cause serious side effects, interact with HIV drugs, or be costly, safer and more affordable treatment options are needed. Genistein is a natural compound found in soy foods. It is considered safe and has been shown to reduce inflammation and improve blood vessel health. This study will test whether genistein can lower inflammation in the blood, improve blood vessel health, and reduce pain in PLHIV.
