aspirin ↔ imipramine
Applies to:aspirin and Tofranil (imipramine)
MONITOR: Preliminary evidence suggests that aspirin may increase the plasma free concentration and pharmacologic effects of imipramine by displacing it from plasma protein binding sites. In 20 patients with endogenous depression given imipramine 150 mg/day for 5 days, administration of aspirin (500 mg every 12 hours for 2 days) decreased the plasma protein binding of imipramine from 84% to 72%. Additionally, the incidence of mild and severe adverse effects associated with imipramine increased nearly 60% and 150%, respectively. Other salicylates are expected to have similar effects due to their high affinity for plasma proteins.
MANAGEMENT: Pharmacologic response to imipramine should be monitored more closely whenever a salicylate is added to or withdrawn from therapy, and the imipramine dosage adjusted as necessary. Patients should be advised to notify their physician if they experience increased adverse effects of imipramine such as dry mouth, constipation, urinary retention, blurred vision, palpitations, and tachycardia.

| 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. |
