International experience with tenoxicam: a review

Area of Science:

• Pharmacology
• Clinical Research
• Drug Safety

Background:

• Assessing the side-effect profile of new drugs requires extensive data collection.
• Different methodologies exist for gathering drug safety information, including open and stringent databases, and randomized controlled trials.

Purpose of the Study:

• To compare the side-effect profiles of tenoxicam and piroxicam using data from multiple sources.
• To evaluate the safety of tenoxicam in comparison to other non-steroidal anti-inflammatory drugs (NSAIDs).

Main Methods:

• Analysis of a UK patient database (4,125 on tenoxicam, 1,132 on comparators) with comprehensive event reporting.
• Review of an international database (5,537 on tenoxicam, 2,948 on comparator NSAIDs) with physician-reported events.
• A randomized, double-blind UK study comparing tenoxicam (657 patients) and piroxicam (663 patients) at 20 mg/day.

Main Results:

• All data collection methods indicated a trend of fewer serious gastrointestinal side-effects with tenoxicam versus piroxicam.
• Statistical significance for reduced gastrointestinal side-effects was not achieved, even with homogeneous populations.
• The overall side-effect profile of tenoxicam was comparable to piroxicam and other NSAIDs.

Conclusions:

• Tenoxicam appears to have a favorable gastrointestinal safety profile compared to piroxicam.
• Further research may be needed to achieve statistical significance for observed differences in gastrointestinal side-effects.
• Tenoxicam exhibits a safety profile consistent with other NSAIDs.
