Feldene is a brand name for the pharmaceutical compound piroxicam. It is classified as a nonsteroidal anti-inflammatory drug used to relieve pain and inflammation. The medication works by inhibiting the enzyme cyclooxygenase which reduces the production of prostaglandins. By decreasing prostaglandin levels the drug diminishes pain signaling and swelling in the body. This mechanism provides therapeutic benefit for conditions such as arthritis and joint stiffness. The overall effect is a modest reduction of inflammation that helps improve mobility.

Feldene is a prescription medication classified as a nonsteroidal anti-inflammatory drug. It is used to relieve pain and inflammation in conditions such as osteoarthritis and rheumatoid arthritis. The drug selectively inhibits the cyclooxygenase-2 enzyme to reduce prostaglandin production. This action decreases inflammatory mediators that cause swelling, fever and discomfort. The selective inhibition spares normal tissue while still providing strong anti-inflammatory effects. The resulting drop in prostaglandins leads to lower fever, reduced pain and less tissue swelling. Oral administration allows the drug to be absorbed into the bloodstream and delivered to inflamed joints. When it reaches the site of inflammation it yields measurable improvement in mobility and function for patients.

Feldene may cause gastrointestinal discomfort such as nausea or abdominal pain. Some users report skin reactions like rash or itching. Dizziness or headache can occur during treatment. Fluid retention leading to swelling of the ankles or feet has been reported. Elevated blood pressure has been observed in a minority of patients. Rarely, visual disturbances such as blurred vision may appear. Fatigue or general weakness may also be experienced.
