For What Indications are Antidepressants Being Used in Adults in Colombia?

INTRODUCTION

Antidepressants are useful in the pharmacological treatment of different depressive and anxiety disorders, as well as being potentially useful in other indications. The aim of the study was to determine the indications for which antidepressants are being prescribed in patients over 18 years of age registered with the Colombian Health System.

METHODS

Retrospective study with data from patients over 18 years old, of either sex, registered with the Colombian Health System, who are prescribed antidepressants. Medical records were reviewed, looking for indications approved and not approved by regulatory agencies. Patients were identified randomly, as well as the sociodemographic, clinical and pharmacological variables that could be associated with prescriptions for unapproved indications.

RESULTS

351 patients were evaluated, with a mean age of 60.4±15.3 years, of whom 72.6% were women. They were attended in 34 cities, with prescriptions mainly by general practitioners (n=276; 78.6%), and psychiatrists (n=42; 12.0%). Selective serotonin reuptake inhibitors were the most widely prescribed antidepressants (n=204; 58.1%), followed by atypicals (n=76; 21.7%). The most frequent indications were for depression (n=169; 48.1%), anxiety (n=48; 13.7%), pain (n=22; 6.3%) and sleep disorders (n=17; 4.8%). A total of 188 prescriptions (53.6%) were made for approved indications, and the remaining 163 (46.4%) were classified as unapproved.

CONCLUSIONS

Antidepressants are being prescribed for the treatment of depression, anxiety, pain and sleep disorders, especially in older adult women, but almost half of the formulations were for unapproved indications.
