Inflammation  is t he reaction of a part of the body to injury or infection, characterized by swelling, heat, redness, and pain. The process includes increased blood flow with an influx of white blood cells and other chemical substances that facilitate healing. Cyclooxygenase  (COX), officially known as prostaglandin-endoperoxide synthase (PTGS), is an enzyme (specifically, a family of isozymes, EC 1.14.99.1) that is responsible for formation of prostanoids, including thromboxane and prostaglandins such as prostacyclin. The  prostaglandins  (PG) are a group of physiologically active lipid compounds having diverse hormone-like effects in animals. Q: Why does your body temperature rise when you have the flu? A : " Your body temperature rises when you have the flu as a way of fighting off the influenza virus; viruses thrive best at 98.6 degrees Fahrenheit—normal body temperature. When your body is hotter it's harder for the flu virus to survive. A...

Abstract The widely used non-steroidal anti-inflammatory drugs (NSAIDs) function mainly through inhibition of cyclooxygenases 1 and 2 (Cox-1 and Cox-2). Unlike Cox-1, Cox-2 is considered an inducible and pro-inflammatory enzyme. We previously reported that Cox-2 is upregulated in activated human B lymphocytes and using Cox-2 selective inhibitors that Cox-2 is required for optimal antibody synthesis. It is not known whether commonly used non-prescription and non-Cox-2 selective drugs also influence antibody synthesis. Herein, we tested a variety of Cox-1/Cox-2 non-selective NSAIDs, namely ibuprofen, tylenol, aspirin and naproxen and report that they blunt IgM and IgG synthesis in stimulated human peripheral blood mononuclear cells (PBMC). Ibuprofen had its most profound effects in inhibiting human PBMCs and purified B lymphocyte IgM and IgG synthesis when administered in the first few days after activation. As shown by viability assays, ibuprofen did not kill B cells. The implication...

You should wonder if a medication you often take for pain is safe. There are some misconceptions about NSAIDS (ibuprofen, naproxen, Motrin, Advil) and some truths. How much can or should you take and is it bad for your liver or kidneys? Every week I’m asked this question. How much? For the treatment of mild to moderate pain, minor fever, and acute or chronic inflammatory conditions 200 mg to 400 mg of ibuprofen will work, and is comparable to 650 mg of acetaminophen (Tylenol) or aspirin. Generally taken every 6 to 8 hours, the maximum dose of NSAIDs per day is 2400 mg which is 12 over-the-counter tablets. Liver-safe: Ibuprofen and other NSAIDS rarely affect the liver. Unlike acetaminophen (Tylenol) most NSAIDs are absorbed completely and have negligible first-pass hepatic (liver) metabolism. In other words, the way NSAIDS are metabolized makes liver toxicity (hepatotoxicity) very rare. Estimates are that 1 in 100,000 NSAID prescriptions result in acute liver injury. Generally ...
