Carbamazepine extended-release capsules: a retrospective review of its use in children and adolescents.
BACKGROUND
Bipolar disorder occurs in 1% of children and adolescents, but few clinical trials address treatment of this population. This retrospective chart review evaluated the long-term safety and tolerability of carbamazepine extended-release capsules (CBZ-ERC) (Shire, Wayne, PA, USA) in 300 children and adolescent patients who had been treated for bipolar disorder in a private psychiatric practice.


METHODS
Data were collected from the medical records of all young and adolescent (4-17 years old) patients who met the DSM-IV criteria for a diagnosis of bipolar disorder type I, type II, or bipolar not otherwise specified who had been treated with CBZ-ERC either as add-on or monotherapy between October 1998 and November 2003 at Red Oak Psychiatry Associates, Houston, TX. The severity of illness was assessed using the Clinical Global Impression-Severity scale, and improvement was measured by the Clinical Global Impression-Improvement (CGI-I) scale.


RESULTS
A response, defined as a CGI-I score of <or=3, was achieved in 76% of patients, 90% of whom were at least markedly ill (CGI-I>or=5) at CBZ-ERC initiation. Treatment was well tolerated, with the most common adverse events being somnolence (9.7%), nausea (6.3%), dizziness (5.0%), and rash (4.3%).


CONCLUSIONS
Carbamazepine extended-release capsules appear safe and efficacious for the treatment of bipolar disorders in children and adolescent patients.
