antiscychotic drug
  • Aripiprazole is an antiscychotic drug which belongs to atypical antipsychotic group.
  • Abilex® tablets are 87% bioavailable and reach peak plasma concentrations in 3 to 5 hours.
  • These tablets can be taken with or without food, but a high fat meal can delay the time to max concentration by 3 hours and up to 12 hours for the active metabolite.
  • Protein binding of Aripiprazole is >99% 
  • The half life of Aripiprazole is 75 hours while the half life of the active metabolite is 94 hours. Elimination of Aripiprazole is mainly through hepatic metabolism involving two P450 isozymes, CYP2D6 and CYP2D6. For populations that are poor CYP2D6 metabolizers, the half life of Aripiprazole is 146 hours and these patients should be treated with half the normal dose.

Each tablet of Abilex® contains: 

  • Aripiprazole                     20 mg

¤ The oral formulations of Abilex® are indicated for:

  • Schizophrenia
  • Acute Treatment of Manic and Mixed Episodes associated with Bipolar I
  • Adjunctive Treatment of Major Depressive Disorder 
  • Irritability Associated with Autistic Disorder 
  • Treatment of Tourette’s disorder

¤ Abilex® tablets can not be used, if

  • the patient is allergic to Aripiprazole.
  • Reactions have ranged from pruritus/urticaria to anaphylaxis.
  • Using strong CYP3A4 Inhibitors (e.g., itraconazole, clarithromycin) or strong CYP2D6 inhibitors (e.g., quinidine, fluoxetine, paroxetine) concomitantly with Abilex® will increase the exposure of Aripiprazole compared to the use of Abilex® alone. Consequently, reducing the Abilex® dosage is clinically recommended.
  • Using strong CYP3A4 Inducers (e.g., carbamazepine, rifampin), concomitantly with Abilex® will decreased the exposure of aripiprazole compared to the use of Abilex® alone. Therefore, increasing the Abilex® dosage is clinically recommended.
  • Antihypertensive Drugs: Aripiprazole has the potential to enhance the effect of certain antihypertensive agents due to its alpha adrenergic antagonism so monitoring blood pressure and adjust dose accordingly is clinically recommended.
  • Benzodiazepines (e.g., lorazepam), intensity of sedation and orthostatic hypotension for using Aripiprazole and lorzepam together were greater than using each one alone so monitoring sedation and blood pressure and Adjust dose accordingly is clinically recommended.
  • Pregnancy: may cause extrapyramidal and/or withdrawal symptoms in neonates with third trimester exposure 
  • Lactation: There are reports of poor weight gain in breastfed infants exposed to aripiprazole and reports of inadequate milk supply in lactating 

¤ Commonly observed adverse reactions (incidence ≥5% and at least twice that for placebo) were:

  • Adult patients with schizophrenia: akathisia
  • Pediatric patients (13 to 17 years) with schizophrenia: extrapyramidal disorder, somnolence, and tremor.
  • Adult patients (monotherapy) with bipolar mania: akathisia, sedation, restlessness, tremor, and extrapyramidal disorder
  • Adult patients (adjunctive therapy with lithium or valproate) with bipolar mania: akathisia, insomnia, and extrapyramidal disorder
  • Pediatric patients (10 to 17 years) with bipolar mania: somnolence, extrapyramidal disorder, fatigue, nausea, akathisia, blurred vision, salivary hypersecretion, and dizziness
  • Adult patients with major depressive disorder (adjunctive treatment to antidepressant therapy): akathisia, restlessness, insomnia, constipation, fatigue, and blurred vision
  • Pediatric patients (6 to 17 years) with autistic disorder: sedation, fatigue, vomiting, somnolence, tremor, pyrexia, drooling, decreased appetite, salivary hypersecretion, extrapyramidal disorder, and lethargy
  • Pediatric patients (6 to 18 years) with Tourette’s disorder: sedation, somnolence, nausea, headache, nasopharyngitis, fatigue, increased appetite
  • Adult patients with agitation associated with schizophrenia or bipolar mania: nausea.


¤ Patients who have taken too much Abilex® tablets have experienced the following symptoms:

  • rapid heartbeat, agitation/aggressiveness, problems with speech.
  • Unusual movements (especially of the face or tongue) and reduced level of consciousness.

Immediate consultation of doctor must be taken if the above manifestations are experienced.
