PainRelief.com: What is the background for this study? What are the main findings?
Response: Osteoarthritis Research Society (OARSI) guidelines include topical non-steroidal anti-inflammatory drugs (NSAIDs) as a level 1A recommendation for non-operative management of knee osteoarthritis, but previous reviews have demonstrated that clinical adoption of this treatment option lags. We conducted a systematic review and meta-analysis of 18 studies evaluating diclofenac, ketoprofen, and ibuprofen in topical preparations. We found that they are safe and effective for reducing pain and improving physical function in patients with knee osteoarthritis. Diclofenac had the strongest quality and number of studies and showed a moderate effect size for symptomatic improvement. With regards to safety, adverse events were low in the topical treatment groups, and topical preparations containing dimethyl sulfoxide (DMSO) showed a higher odds ratio for adverse events than preparations without DMSO.

PainRelief.com: What is the background for this study?
Response: The addition of L-arginine to the molecule of ibuprofen, a non-steroidal anti-inflammatory drug (NSAID), in the salt form of ibuprofen arginate has the rationale to enhance the absorption rate of the active S-(+) enantiomer of ibuprofen to achieve a rapid onset analgesic action. Despite availability of ibuprofen arginate in the market for many years, a comprehensive review of the evidence of the analgesic efficacy, tolerability and safety in different pain models has not been previously reported.

MedicalResearch.com: What actions is FDA taking regarding NSAID use during pregnancy?
Response: The U.S. Food and Drug Administration (FDA) is warning that use of prescription or over-the-counter (OTC) nonsteroidal anti-inflammatory drugs (NSAIDs) from around 20 weeks of pregnancy through the end of pregnancy may cause rare but serious kidney problems in an unborn baby. This can lead to low levels of amniotic fluid surrounding the unborn baby and possible complications.
For prescription NSAIDs, FDA is requiring changes to the prescribing information to describe the risk of kidney problems in unborn babies; these kidney problems can result in low amniotic fluid. FDA is recommending that pregnant women avoid NSAIDs from around 20 weeks of pregnancy. Prescribing information already recommends avoiding NSAIDs from around 30 weeks through the end of pregnancy because NSAIDs can cause a problem that may result in heart issues in the unborn baby. If NSAID use is necessary between 20 and 30 weeks of pregnancy, NSAID use should be limited to the lowest effective dose for the shortest possible duration. Health care professionals should consider ultrasound monitoring of amniotic fluid if a pregnant woman uses NSAIDs beyond 48 hours.
FDA will also work with sponsors to request updates of the Drug Facts labels of OTC NSAIDs intended for use in adults. These labels already warn to avoid using NSAIDs during the last three months of pregnancy because the medicines may cause problems in the unborn baby or complications during delivery. The Drug Facts labels also already advise pregnant and breastfeeding women to ask a health care professional before using these medicines.
MedicalResearch.com: What did FDA find?
Response: These labeling changes are based on cases reported to FDA about low amniotic fluid levels or kidney problems in unborn babies associated with NSAID use during pregnancy. FDA’s medical literature review also contributed to the basis for the labeling changes.
Among the 35 cases of low amniotic fluid levels or kidney problems reported to FDA through 2017, all were serious. Two newborns who died had kidney failure and confirmed low amniotic fluid when mothers took NSAIDs while pregnant; three other newborns who died had kidney failure without confirmed low amniotic fluid when mothers took NSAIDs while pregnant. The low amniotic fluid levels started as early as 20 weeks of pregnancy. In 11 cases where low amniotic fluid levels were detected during pregnancy, the fluid volume returned to normal after the woman stopped taking the NSAID.
FDA’s medical literature review yielded similar findings. In these publications, low amniotic fluid levels were detected with NSAID use for varying amounts of time, ranging from 48 hours to multiple weeks. In most cases, the condition was reversible within three to six days after stopping the NSAID. In many reports, the condition was reversed when the NSAID was stopped; the condition reappeared when the same NSAID was started again.
MedicalResearch.com: What are NSAIDs? Are all NSAIDs included in the new FDA recommendations to avoid NSAID use from around 20 weeks through the end of pregnancy?
Response: For decades, people have used NSAIDs to treat pain and fever from many different long- and short-term medical conditions, such as arthritis, menstrual cramps, headaches, colds, and the flu. NSAIDs work by blocking the production of certain chemicals in the body that cause inflammation. There are both prescription and OTC NSAIDs.
NSAIDs are available alone and combined with other medicines for the temporary relief of pain and fever, including pain or fever symptoms associated with colds, flu, and insomnia. Examples of NSAIDs include ibuprofen (Advil, Motrin), naproxen (Aleve), diclofenac (Voltaren), and celecoxib (Celebrex) and aspirin.
An exception to these new FDA recommendations is the use of the low-dose aspirin (81 mg) for certain pregnancy-related conditions at any point in pregnancy under the direction of a health care professional. Low-dose aspirin may be an important treatment for some women during pregnancy. The recommendations also do not apply to NSAIDs administered directly to the eye.
MedicalResearch.com: NSAIDs already carry a warning about use in late pregnancy. What is different about these labeling changes?
Response: Warnings to avoid taking NSAIDs after about 30 weeks of pregnancy are already included in the prescribing information because taking these medications during this time may lead to heart issues in the unborn baby. The new labeling changes recommend avoiding NSAIDs as early as about 20 weeks of pregnancy because of the risk of kidney problems that result in low amniotic fluid.
MedicalResearch.com:What should pregnant women and health care professionals do? What are other options for pain relief during pregnancy?
Response: Women should not use NSAIDs after around 20 weeks in pregnancy unless specifically advised to do so by a health care professional. Because many OTC medicines contain NSAIDs, pregnant women should read the Drug Facts labels to determine if the medicines contain an NSAID. If pregnant women are unsure if a medicine contains an NSAID, they should ask a pharmacist or health care professional for help.
Other medicines, such as acetaminophen (Tylenol), are available to treat pain and fever during pregnancy. Pregnant women should ask their pharmacist or health care professional for help deciding which medication might be best.
Health care professionals should limit prescribing NSAIDs between 20 to 30 weeks of pregnancy and avoid prescribing them after 30 weeks of pregnancy. If NSAID treatment is determined necessary, health care professionals should limit use to the lowest effective dose and shortest duration possible. They should also consider ultrasound monitoring of amniotic fluid if the pregnant woman regularly uses NSAIDs longer than 48 hours and discontinue the NSAID if low amniotic fluid levels are found.

PainRelief.com: What is the background for this study?
Response: Early in the COVID-19 pandemic, concerns were raised that use of the common painkiller ibuprofen – a so-called NSAID – to treat symptoms of COVID-19 might lead to more severe disease. This started with tweets from the French health minister and culminated with a warning issued by the WHO. This warning was later retracted, but naturally patients and physicians were concerned regarding the safety of ibuprofen. We therefore established a nationwide Danish collaboration between researchers and regulators and established a prospective cohort of all Danish patients that contracted COVID-19, including data on what prescription medicines they used. We used these data to evaluate whether users of ibuprofen or other NSAIDs on average had a more severe course of COVID-19 than those not using these drugs.
PainRelief.com Interview with: Timothy Wilt, MD, MPH Chair ACP Clinical Guidelines Committee Professor of Medicine Minneapolis VA Center for Care Delivery and Outcomes Research.
PainRelief.com: What is the background for this study? What are the main findings?
Response:Acute non-low back musculoskeletal pain is common, disabling and costly. Most are treated in outpatient settings. Numerous pharmacologic and nonpharmacologic treatment options exist but there is uncertainty of their benefits, harms and costs. Additionally, opioid prescriptions are common for acute musculoskeletal injuries but have harms and can lead to chronic opioid use including dependence and overdose. ACP and AAFP developed these evidence based guidelines to assist clinicians in providing the highest quality care to their patients by considering information on benefits, harms and costs alongside patient values and preferences. Our main recommendations are as follows:
1) ACP and AAFP recommend that clinicians treat patients with acute pain from non–low back, musculoskeletal injuries with topical nonsteroidal anti-inflammatory drugs (NSAIDs) with or without menthol gel as first-line therapy to reduce or relieve symptoms, including pain; improve physical function; and improve the patient’s treatment satisfaction.
2) ACP and AAFP suggest that clinicians treat patients with acute pain from non–low back, musculoskeletal injuries with oral NSAIDs to reduce or relieve symptoms, including pain, and to improve physical function, or with oral acetaminophen to reduce pain.
3) ACP and AAFP suggest that clinicians treat patients with acute pain from non–low back, musculoskeletal injuries with specific acupressure to reduce pain and improve physical function, or with transcutaneous electrical nerve stimulation to reduce pain.
4) ACP and AAFP suggest against clinicians treating patients with acute pain from non–low back, musculoskeletal injuries with opioids, including tramadol.

PainRelief.com: What is the background for this study?
Response: While many over the counter non-steroidal anti-inflammatory drugs (NSAIDs) now include a warning about potential cardiovascular disease, warnings about liver injury are hardly mentioned. This is because most NSAIDs including ibuprofen is considered to have very little potential to cause liver toxicity.
However, a 2018 publication (doi: https://doi.org/10.1016/j.cgh.2017.07.037) showed a relatively high prevalence of ibuprofen -induced liver injury in Spanish and Latin-American DILI (Drug induced liver injury) registries. As such, we were interested in determining what effects, if any, ibuprofen had on mice liver.

PainRelief.com: What is the
background for this study? What are the
main findings?
Response: About 29 million Americans use over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) to treat pain. Every year in the United States (US), NSAID use is attributed to approximately 100,000 hospitalizations and 17,000 deaths. In addition, the U.S. Food and Drug Administration recently strengthened its warning about risks of non-aspirin NSAIDs on heart attacks and strokes.
While each over the counter and prescription pain reliever has benefits and risks, deciding which to use is complicated for healthcare providers and their patients.

PainRelief.com: What is the background for this study?
Response: The purpose of this study was to describe and compare rates of physicians’ recommendation for physical therapy (PT), lifestyle-counseling, and pain medication for knee osteoarthritis (KOA) between 2007 and 2015. The study also aimed to identify patient, physician and practice-level factors associated with each treatment recommendation. We used survey data from the National Ambulatory Medical Care Survey, data from this survey is publicly available and is housed within the CDC. We identified 2297 knee OA related visits, which approximated to 67 (±4) million weighted physician visits between 2007 and 2015 (around 8 million visits/year).

PainRelief.com: What is the
background for this study? What are the
main findings?
Response: Though the higher rates of certain adverse events due to NSAIDs are well documented, we were curious about how soon these adverse events can begin to manifest. We were similarly interested in the efficacy trajectories of NSAIDs, because previous studies had conducted analyses of the last reported follow-up times for the drugs, but we noticed that many of the studies had only very short-term follow up ranging between 1-4 weeks which didn’t provide a more complete picture of the therapeutic effect over time.
The key findings of our study are that the widely used NSAIDs are very effective for short-term pain relief but their efficacy wanes over a period of 12 weeks. The adverse events though mild in nature start appearing within 4 weeks of treatment.
