Indications
- Pain and inflammation in rheumatoid arthritis, osteoarthritis
- Ankylosing spondylitis
Administration
Oral 10-30mg daily
max 20mg[1]
IM
Topical
Clinical Issues
It has proven efficiency in soft tissue injury compared to placebo and seems to be widely used in soft tissue injury, sometimes outside its license. It has also been used in acute gout. Its license for these indications were withdrawn in 2007 in the EU due to skin side effects and other relative safety factors.
Piroxicam-containing medicines should no longer be used for the treatment of acute (short-term) pain and inflammation.[2]
Interestingly:
- It doesn't provide pain relief as quickly as paracetamol but does last longer.
- It is not as quick or effective as diclofenac in ankle sprains[3] but appears to be better than aspirin or naproxen.[4]
- The topical preparation may not be as effective as alternatives. "With analysis by drug (at least three trials), ketoprofen (number needed to treat 2.6), felbinac (3.0), ibuprofen (3.5), and piroxicam (4.2) had significant efficacy."[5]
Contra-indications
Cautions and Interactions
Side effects
Commoner important
- Upper gastro-intestinal. All NSAIDs are associated with serious gastrointestinal side effects. For non-selective NSAIDs these were most common with azapropazone and least common with Ibuprofen. Selective cyclo-oxygenase-2 inhibitors are associated with a lower risk of gastrointestinal side effects
- Dyspepsia
- Haemorrhage
- Renal failure (especially in combination with diuretics and drugs acting on angiotensin system)
- Fluid retention
Rarer Important
- Cardiovascular events. This may be related to degree of cyclo-oxygenase-2 inhibition
- Asthma
- In chronic heart failure all NSAIDS have a dose-dependent increase in risk of death and increased risk of hospitalization with some such as diclofenac and coxibs having higher hazard ratios[6]
