A subgroup analysis from VOYAGER PAD found that adding clopidogrel to rivaroxaban and aspirin after lower extremity revascularization procedures did not provide any added clinical benefit for patients with peripheral artery disease. Instead, it increased the risk of bleeding events.
A randomized trial found that ticagrelor alone reduced major bleeding risk and no increased heart attacks, strokes, or other adverse events compared to dual therapy. The study suggests ticagrelor monotherapy as an optimal strategy for reducing bleeding risk in ACS patients treated with stents.
A study led by King's College London researchers analyzed existing studies on coronavirus strains to determine the safety of pain medications, steroids, and other drugs for patients with COVID-19. The study found that non-steroidal anti-inflammatory drugs like ibuprofen are not evidence against their use in treating COVID-19.
A subgroup of high-risk patients with complex heart disease who took ticagrelor alone had fewer episodes of bleeding and no increase in heart attacks or stroke. Ticagrelor monotherapy significantly reduced clinically relevant bleeding without increasing the risk of additional heart attacks, strokes or death.
A pair of new studies indicate parents are more reluctant to have opioids prescribed for their children than doctors, citing fears of addiction and side-effects. Pediatricians emphasize the importance of treating children's pain while acknowledging the unknown risks of opioid treatment.
Researchers have developed highly selective ligands to label opioid receptors, shedding light on their behavior in living cells. The study reveals that most opioid receptors exist as individual entities, but a small proportion forms pairs, which may contribute to the receptor's function.

A new study suggests that roughly half of opioid prescriptions written by dentists in the US exceed federal guidelines for pain management. Dental procedures like extractions can lead to significant pain, and researchers found that some dentists are overprescribing opioids as a result.
A survey of over 2,700 kratom users found the substance has a lower rate of harm than prescription opioids for treating pain, anxiety, and depression. While self-reporting surveys are not always reliable, the results suggest kratom may have medical applications to explore as an alternative to opioid use.

A new US study demonstrates the effectiveness of genicular artery embolization (GAE) in treating osteoarthritis knee pain. The minimally invasive procedure blocks blood flow to certain parts of the knee, providing rapid relief from pain and disability. Results show significant improvement in pain scores, with nearly all patients experi...
A new Boston University School of Public Health study found that the decline in prescriptions of non-opioid analgesics coincided with a marked increase in opioid prescribing. The study suggests that health risks associated with NSAIDs were one factor that led to increased prescribing of opioids.
A study published by the American Heart Association found that low-dose aspirin did not reduce the risk of a fatal heart attack among African Americans, unlike in white populations. The study used data from over 65,000 participants and suggested genetic differences and poor control of other risk factors may contribute to this result.
A recent review found that aspirin no longer provides a net benefit for primary prevention of cardiovascular disease and cancer, despite its long history of reducing heart attack risk. Aspirin use has decreased in recent years due to the emergence of statins and improved cancer screening technology.
A new study suggests that taking aspirin daily to prevent a heart attack or stroke may no longer be recommended for adults without a history of these events. The study found that the potential benefits of aspirin are similar to its potential harms for most people, highlighting the need for personalized advice from doctors.
A new UCLA-led study suggests chronic opioid treatment may raise the risk of post-traumatic stress disorder (PTSD) in individuals who are likely to experience severe emotional stress. Researchers found that mice given morphine before and after a traumatic event showed enhanced fear learning, indicating increased PTSD susceptibility.
Researchers at Harvard Medical School have launched a project to develop preclinical drug candidates that selectively block nociceptor activity, offering an alternative to opioid-based medications. The STOP PAIN consortium combines experimental and AI-driven approaches to address the critical public health need for new pain treatments.
Scientists have discovered the binding mechanism of an important pain receptor, which could lead to the development of new active substances. The current study aimed to find alternatives to opioids used today, as they can be addictive and have life-threatening side effects.
West Virginia University researcher Shane Kaski found that combining nalfurafine with morphine reduces pain while minimizing morphine's addictive potential. This could lead to lower doses of morphine and reduced risk of addiction, combating the opioid epidemic.
Researchers found yoga and physical therapy significantly improved sleep quality for 52 weeks after 12-week treatment. Participants with early pain improvements were three times more likely to have better sleep outcomes.
In a randomized clinical trial, adults with moderate to severe migraines took either ubrogepant or a placebo. After two hours, participants reported a significant reduction in pain and associated symptoms. The study provides encouraging results for the treatment of migraine pain.
Researchers at FEFU developed a method to synthesize biologically active derivatives of fascaplysin, a compound found in sea sponges. The new compounds, including 14-bromoreticulatine and 3,10-dibromofascaplysin, show selective effects on cancer cells, particularly Pseudomonas Aeruginosa bacteria and human prostate cancer cells.
Researchers found a 95% increased risk of frailty among those who self-reported regular use of prescription pain and/or sleep medications. Co-use of multiple prescription medications also increased frailty risk, with effects observed for pain-only and sleep-only prescriptions.
Researchers found small, statistically significant benefits on pain and function with opioids, but no impact on quality of life or depression for patients with osteoarthritis. Strong opioids had consistently worse pain relief benefits and a greater risk of adverse events compared to weak opioids.
Non-Hispanic black and Hispanic women reported higher pain scores compared to white women during the postpartum period. Despite this, they received fewer opioids and were less likely to receive prescriptions at discharge.
Researchers have discovered a class of analgesics in conotoxin peptides, which are found in the venom of marine cone snails. These peptides show exceptional potency and selectivity for ion channels involved in pain transmission, offering new avenues for pain therapy.
Researchers developed a novel nanoparticle delivery method to treat pain, using a non-opioid drug that previously failed clinical trials. The approach successfully treated pain in mice and rats with improved efficacy and duration of action.
A new study at Kellogg Eye Center finds that reducing opioid pills prescribed after cornea surgery doesn't compromise pain control, with most patients using only four pills. The policy change also leads to more responsible pill disposal practices.
A recent NIH-funded study suggests that exposure to acetaminophen during pregnancy may increase the risk of attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in children. The study found that higher levels of acetaminophen exposure were associated with a significantly increased risk of both conditions.
Researchers found an association between aspirin use and decreased intracranial aneurysm growth rate. Growth is crucial as it increases rupture risk. The study suggests that aspirin may exert a protective effect against aneurysm growth and future rupture, but findings are observational and require further interventional studies.
