A retrospective audit of prescriptions issued for outpatients was carried out at the Psychiatric Hospital, the only facility that provides psychiatric services for both inpatients and outpatients in the Kingdom of Bahrain. Antipsychotic monotherapy was prescribed for 89.2% patients, whereas polytherapy with two- and three-drugs in 10.4 and 0.4%, respectively. Atypical antipsychotics were prescribed more often (67.7%) than typical antipsychotics. Risperidone and haloperidol were the most frequently prescribed antipsychotics. Long-acting risperidone injection was the only depot preparation prescribed. The mean antipsychotic dose expressed as chlorpromazine equivalent (CPZeq;mg/day) was 242 (220 for monotherapy and 414 for polytherapy). The prevalence of high dose antipsychotic (mean CPZeq > 1000 mg/day) was 1.8%, prescribed at a mean CPZeq dose of 1531 (1925 for monotherapy and 1137 for polytherapy), mainly attributed to haloperidol. Anticholinergics were co-prescribed for almost two third of patients receiving antipsychotics, particularly for those on polytherapy (monotherapy 57.3%;poly-therapy 87.5%). Antipsychotic polytherapy, high dose and co-prescription of an oral with a depot antipsychotic preparation were strongly associated with concurrent prescription of anticholinergics. Procyclidine and orphenadrine were the most often prescribed anticholinergics. In Bahrain, antipsychotic monotherapy is a common practice for outpatients with psychotic disorders. Some of the antipsychotic polytherapies, dosage strategies, and high prevalence of anticholinergic use are therapeutic issues that need to be addressed to foster evidence-based prescribing practice.展开更多

We have analyzed the prescribing trends and the likelihood of psychotropic-associated sexual dysfunction in outpatients with depression or other psychotic disorders treated by psychiatrists. A retrospective prescription audit was conducted at the Psychiatric Hospital, the only psychiatric facility in Bahrain that offers both inpatient and outpatient services. Psychotropic associated sexual dysfunction was graded as negligible (0), moderate (2+), moderately severe (3+) and uncertain (U) for antidepressants, and for antipsychotics as no effect (0), very low (1+), moderate (2+), moderately severe (3+) and uncertain (U) effect. As antidepressant monotherapy, a significant trend towards prescribing selective serotonin reuptake inhibitors (SSRIs;3+) and selective norepinephrine reuptake inhibitors (SNRIs;3+) in females, and tricyclic antide-pressants (TCAs;2+) in males was apparent. Atypical antidepressant mirtazapine (0) monotherapy was rarely prescribed. Mirtazapine with SSRIs or SNRI was the most often prescribed combinations followed by TCAs with other antidepressants. Risperidone (0 to 3+), an atypical antipsychotic, was the most popular antipsychotic prescribed to augment antidepressants;there was no gender-based difference. Clozapine (0) and olanzapine (1+) were rarely prescribed to augment antidepressant therapy. In Bahrain, the psychotropic prescribing trends suggest that there is a need to optimize drug therapy to achieve the therapeutic goal with minimal adverse impact on sexual function.展开更多
