Aripiprazoleinteractions

Dosage adjustments for patients taking CYP2D6 inhibitors, CYP3A4 inhibitors, or CYP3A4 inducers for greater than 14 days: Factors Dosage Recommendation CYP2D6 Poor Metabolizers taking concomitant CYP3A4 inhibitors Avoid use Patients taking strong CYP2D6 or CYP3A4 inhibitors 720 mg For the 1-day initiation regimen, administer a single 20 mg oral aripiprazole, 300 mg Abilify Maintena and 720 mg ABILIFY ASIMTUFII on Day 1. Patients taking CYP2D6 and CYP3A4 inhibitors Avoid use Patients taking CYP3A4 inducers Avoid use

Clinically Important Interactions with ABILIFY ASIMTUFII Table 7 presents clinically significant drug interactions with ABILIFY ASIMTUFII.

Table 7: Clinically Important Drug Interactions with ABILIFY ASIMTUFII Strong CYP3A4 Inhibitors AND/OR strong CYP2D6 inhibitors Clinical Rationale Concomitant use of oral aripiprazole with strong CYP3A4 AND/OR CYP2D6 inhibitors increased the exposure of aripiprazole. Clinical Recommendation Concomitant use of a strong CYP3A4 inhibitor OR a strong CYP2D6 inhibitor Reduce the dosage of ABILIFY ASIMTUFII when administered concomitantly with a strong CYP3A4 inhibitor OR a strong CYP2D6 inhibitor for more than 14 days. Concomitant Use of a strong CYP3A4 inhibitor AND a strong CYP2D6 inhibitor Avoid use of ABILIFY ASIMTUFII when administered concomitantly with a strong CYP3A4 inhibitor AND a strong CYP2D6 inhibitor for more than 14 days. Strong CYP3A4 Inducers Clinical Rationale Concomitant use of oral aripiprazole and carbamazepine decreased the exposure of aripiprazole. Clinical Recommendation Avoid use of ABILIFY ASIMTUFII in combination with a strong CYP3A4 inducer (e.g., carbamazepine) for greater than 14 days. Antihypertensive Drugs Clinical Rationale Due to its alpha-adrenergic antagonism, aripiprazole has the potential to enhance the effect of certain antihypertensive agents. Clinical Recommendation Monitor blood pressure and adjust dose accordingly. Benzodiazepines Clinical Rationale The intensity of sedation was greater with the combination of oral aripiprazole and lorazepam as compared to that observed with aripiprazole alone. The orthostatic hypotension observed was greater with the combination as compared to that observed with lorazepam alone. Clinical Recommendation Monitor sedation and blood pressure. Adjust dose accordingly.

7.2 Drugs Having

No Clinically Important Interactions with ABILIFY ASIMTUFII Based on pharmacokinetic studies with oral aripiprazole, no dosage adjustment of ABILIFY ASIMTUFII is required when administered concomitantly with famotidine, valproate, lithium, lorazepam. In addition, no dosage adjustment is necessary for substrates of CYP2D6, CYP2C9, CYP2C19, or CYP3A4 when coadministered with ABILIFY ASIMTUFII. Additionally, no dosage adjustment is necessary for valproate, lithium, lamotrigine, lorazepam, or sertraline when coadministered with ABILIFY ASIMTUFII.
