التداخل بين ميكليزين وكينيدين

Quinidine is also contraindicated in patients who, like those with myasthenia gravis, might be adversely affected by an anticholinergic agent.

Altered pharmacodynamics of other drugs: Quinidine's anticholinergic, vasodilating, and negative inotropic actions may be additive to those of other drugs with these effects, and antagonistic to those of drugs with cholinergic, vasoconstricting, and positive inotropic effects.

• CYP2D6 inhibitors: As meclizine is metabolized by CYP2D6, there is a potential for drug-drug interactions between meclizine hydrochloride and CYP2D6 inhibitors ( 7.2 ).

CYP2D6 Inhibitors Based on in-vitro evaluation, meclizine is metabolized by CYP2D6.

Therefore, there is a possibility for a drug interaction between meclizine hydrochloride and CYP2D6 inhibitors.
