Applies to:YSP Aspirin (aspirin) and Anturane (sulfinpyrazone)
GENERALLY AVOID: Salicylates may antagonize the uricosuric effect of sulfinpyrazone. The exact mechanism of interaction is unknown, although therapeutic doses of aspirin have been shown to increase plasma clearance of sulfinpyrazone. In one study, acute pretreatment with aspirin (325 mg four times a day for 24 hours) resulted in increased plasma clearance of a single 400 mg dose of sulfinpyrazone in 5 of 6 subjects by 12% to 27% relative to administration of sulfinpyrazone alone. When sulfinpyrazone 200 mg and aspirin 325 mg were coadministered four times a day for one week, plasma clearance of sulfinpyrazone increased up to 229%. The investigators theorized that aspirin may displace sulfinpyrazone from plasma protein binding sites, resulting in a redistribution of sulfinpyrazone into peripheral compartments and increased amount of free drug for hepatic metabolism. In vitro data also suggest that sulfinpyrazone may interfere with the irreversible effects of aspirin (especially low doses) on platelets, although the clinical significance is unknown.
MANAGEMENT: Salicylates should not be used during sulfinpyrazone therapy for gouty arthritis. However, occasional small doses of salicylates are not expected to interact significantly.

Drug Interaction Classification
The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
