Disse lægemidler omfatter betablokkere (propranolol, carvedilol, timolol), antidepressiva (fluoxetin, paroxetin, sertralin, imipramin, clomipramin), antipsykotika (haloperidol), analgetika (codein, dextromethorphan, tramadol).
As stiripentol inhibited CYP2D6 in vitro at concentrations that are achieved clinically in plasma, drugs that are metabolized by this isoenzyme like: beta-blockers (propranolol, carvedilol, timolol), antidepressants (fluoxetine, paroxetine, sertraline, imipramine, clomipramine), antipsychotics (haloperidol), analgesics (codeine, dextromethorphan, tramadol) may be subject to metabolic interactions with stiripentol.
