Prescription patterns in clinically stable patients with bipolar disorder: Findings from the Bipolar Disorder Course and Outcome from India (BiD-CoIN) study.

AIM

To evaluate the prescription pattern of patients with BD, currently in clinical remission. Additional aim of the study was tocompare the prescription pattern across different study centres.

METHODOLOGY

Prescription of 773 patients, currently in clinical remission, recruited from the outpatient setting of 14 General Hospital Tertiary Care Units of tertiary care centres in the country were evaluated.

RESULTS

Almost all (98.1 %) participants were on medications at the time of assessment. In terms of conventional mood stabilizers, those receiving valproate (44.2 %), out-numbered those receiving lithium (38.9 %). A small proportion (7.4 %) was receiving a combination of both valproate and lithium. About two-third (62.5 %) were receiving at least one antipsychotic medication, with olanzapine (31.7 %) being the most commonly prescribed antipsychotic, followed by quetiapine (11.1 %), and risperidone (9.6 %). About one-third (34.4 %) of the participants were receiving antidepressants, with sertraline (22.6 %) forming bulk of the prescription. Less than half (43.9 %) of the participants were also receiving a benzodiazepine medication at the time of assessment, with chlordiazepoxide (18 %) being the most common agent, followed by clonazepam (14.5 %). There was variation in the prescription patterns across different centres, in terms of monotherapy, polypharmacy, use of preferred conventional mood stabilizers, use of various antipsychotics and antidepressants.

CONCLUSION

Besides conventional mood stabilizers, about two-third of patients with bipolar disorder received concomitant antipsychotics, one-third received concomitant antidepressants and less than half received benzodiazepines.
