The mechanism of action of Abilify is unknown. It shows partial agonism at the D2 receptor, it is also a partial agonist at the 5-HT1A receptor, and also displays an antagonist profile at the 5-HT2A receptor. It has moderate affinity for histamine and alpha adrenergic receptors, and no appreciable affinity for cholinergic muscarinic receptors.

Carbamazepine (Tegretol) decreases the levels of Abilifyole in the body stimulating the liver enzymes such as CYP3A4. Similar influence on Abilify is shown by phenytoin (Dilantin), rifampin (Rifadin, Rimactane, Rifadin, Rifater, Rifamate), and phenobarbital. Blocking of CYP3A4 by Ketoconazole (Nizoral) increases the amount of Abilify in the body. Other drugs with similar action are: itraconazole (Sporanox), fluconazole (Diflucan), voriconazole (Vfend), cimetidine (Tagamet), verapamil (Calan, Isoptin), diltiazem (Cardizem, Dilacor), erythromycin, clarithromycin (Biaxin), nefazodone (Serzone), ritonavir (Norvir), saquinavir (Invirase), nelfinavir (Viracept), indinavir (Crixivan), and grapefruit juice. Their action is not well studied though.
Quinidine (Quinaglute, Quinidex) inhibits another liver enzyme known as CYP2D6 and also is able to increase the levels of Abilify. Other medicines with similar action are fluoxetine (Prozac) and paroxetine (Paxil). Abilify may dangerously increase blood sugar levels in patients with diabetes.
Abilify is taken once daily, so take the missed dose as soon as you remember. If the next dose is within 12 hours, do not take the missed dose and resume your normal dosing schedule. Never double the dose this medication.
