Pattern of psychotropic medications use in a cohort of patients with uninvestigated dyspepsia undergoing upper endoscopy: A retrospective study.

The prevalence of psychotropic drugs usage is growing in the general population. Moreover, patients with dyspeptic symptoms are increasingly referred to the use of psychiatric and antianxiety drugs in addition to the primary medical treatment. The focus of this observational retrospective study was to investigate the burden of psychotropic drugs usage in a cohort of patients with uninvestigated dyspepsia scheduled for esophagogastroduodenoscopy.Medical records of 11,275 patients (4377 men and 6898 women, age range 18-96 years) referred to the Gastroenterology Unit of the University of Sassari, Sardinia, between January 1995 and December 2013 were reviewed. Information regarding any taken medications including psychiatric and antianxiety drugs was collected. Age- and gender-specific frequency of drug usage was calculated, and their association with marital status, smoking habits, place of residence, socioeconomical status, and polypharmacy was investigated by multiple logistic regression analysis.Psychiatric drugs usage was detected in 531 out of 11,275 (4.7%) patients, with preponderance of women (6.1% vs 2.6%, P < 0.0001). The most prescribed drug categories were selective serotonin-reuptake inhibitors and tricyclic antidepressants.The frequency of antianxiety medication use was 9.8% (1009/11,275) and increased with aging, whereas psychiatric drugs reached the plateau in the fifth decade. The cohort effect was remarkable for psychiatric drugs usage in patients born after 1950 compared to those born before (odds ratio: 1.47), whereas it was absent for antianxiety drugs. Conditions significantly associated with psychotropic drugs usage were assumption of more than 2 nonpsychotropic drugs, aging, female gender, smoking, marriage, widowhood, divorce, and socioeconomic status. In contrast, place of residence did not increase the consumption of psychotropic drugs. The influence of marriage and widowhood disappeared after adjusting for all covariates.Our study confirmed the frequent use of psychotropic medications with uninvestigated dyspepsia. However, the pattern of consumption was different for antianxiety and psychiatric drugs.
