Uses

What is tenoxicam used for?

Tenoxicam is part of a class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs), specifically a non-selective cyclooxygenase (COX) inhibitor. NSAIDs are used to treat various causes of pain, inflammation, and swelling. It can also aid in reducing fever.

COX inhibitors work by blocking the action of either or both the COX-1 and COX-1 enzymes. These enzymes are responsible for converting arachidonic acid into prostaglandin, which are a group of substances that regulate many cellular processes such as platelet aggregation, vasodilation, gastric mucus secretion, and proinflammatory mediators.

Tenoxicam is mainly indicated to treat the following conditions:

  • Acute musculoskeletal disorders
  • Osteoarthritis
  • Rheumatoid arthritis

How should I take tenoxicam?

Tenoxicam is available as a vial with a powdered suspension for injection and oral tablets. The parenteral solution is typically administered by a licensed health professional in a clinical setting. It should be reconstituted with sterile water for injection prior to injection, either via IM or IV routes.

The oral tablet should be taken by mouth without chewing or crushing it. The tablets should be taken with food to prevent gastric irritation.
