Use and sources of psychotropic drugs by Brazilian adults and seniors

Use of Psychotropic Drugs during the COVID-19 pandemic in Minas Gerais, Brazil

OBJECTIVE

To describe the profile of dispensation of mental health drugs by analyzing trends in use before and during the COVID-19 pandemic within the Unified Health System (Sistema Único de Saúde [SUS]).

METHODS

Pharmacoepidemiological study based on the retrospective analysis of records regarding the dispensation of psychotropic medicines in the SUS database in the state of Minas Gerais between 2018 and 2021, considering the periods before (2018-2019) and during the COVID-19 pandemic (2020-2021). A database with the records of dispensation of municipalities was created, and the consistency of releases was verified using the Analysis of Variance (ANOVA) test. Medicine consumption was measured in a defined daily dose (DDD) per 1,000 inhabitants/day for SUS, and the difference between periods was evaluated using Student's t-test.

RESULTS

During the COVID-19 pandemic, there was an increase in the consumption of psychotropic drugs in SUS-MG. The most consumed medicines were fluoxetine hydrochloride, diazepam and phenobarbital sodium (DDD=5.89; 3.42; 2.49) in the Basic Pharmaceutical Services Component(CBAF), and olanzapine, risperidone and quetiapine hemifumarate (DDD=0.80; 0.47; 0.38) in the Specialized Pharmaceutical Services Component (CEAF). The highest percentage increase in consumption was attributed to clonazepam (75.37%) and lithium carbonate (35.35%), in CBAF, and levetiracetam (3,000.00%) and memantine hydrochloride (340.0%) in CEAF.

CONCLUSION

The change in the psychotropic drug dispensation profile during the COVID-19 pandemic highlights the need to produce more studies to complete, confirm or rule out this profile and monitor the use of psychotropic drugs by the population in the post-pandemic context.

Dispensing of psychotropic drugs in the Brazilian capital city before and during the COVID-19 pandemic (2018-2020)

Objective: Evaluate the data on the psychotropic drugs dispensed by private community pharmacies before and during the SARS-CoV-2 pandemic. Methods: This cross-sectional study compared the quarterly and annual consumption of psychotropic drugs per Defined Daily Dose per 1000 inhabitants-day (DHD). Interrupted time series were also constructed to expose changes in the consumption pattern in the periods before and after March 2020. Results: Among the 20 most consumed psychoactive drugs, 12 were antidepressants, for example, escitalopram (DHD 7.996 and 10.626; p < 0.001), and sertraline (DHD 6.321 and 8.484; p < 0.001), in addition to the hypnotic zolpidem (DHD 6.202 and 8.526; p < 0.001). The time series reveals (R ² value) a variation in drug dispensing, in DHD values, during the pandemic. Conclusion: Despite the higher variance, a significant increase is clearly seen in the consumption trends of psychoactive drugs, particularly antidepressants, consistent with the pandemic's influence on the general population's mental health.

Use of psychotropic drugs by population in an area affected by the tailings dam rupture: Brumadinho Health Project

OBJECTIVE

To describe the consumption of psychotropic drugs in the adult population residing in Brumadinho, Minas Gerais, after the Vale dam collapse, which occurred in 2019.

METHODS

This is a cross-sectional study, part of the Brumadinho Health Project, developed in 2021, with a representative population-based sample of adults (18 years and over) residing in Brumadinho. A total of 2,805 adults with information on self-reported use of psychotropic drugs (antidepressants and anxiolytics-hypnotics/sedatives) in the last 15 days were included in the analysis. The prevalence of psychotropic drug use was estimated, and the most used psychotropic drugs were identified. Pearson's chi-square test (with Rao-Scott correction) was used to test associations between exposures and use of psychotropic drugs, considering a significance level of p<0.05.

RESULTS

The use of antidepressants (14.2%) was more common than the use of anxiolytics or hypnotics/sedatives (5.2%), with sertraline and fluoxetine being the most used antidepressants. The use of anxiolytics and hypnotics/sedatives was higher among residents who lived in the area directly affected by the dam's mud, and the use of any psychotropic drug was higher among those who lost a relative/friend in the disaster and assessed that their health worsened after the disaster, and among women.

CONCLUSION

The results of the study corroborate what was observed in other populations exposed to similar tragedies, regarding the pattern of associations and the of use of psychotropic drugs.

Trends in Brazilian market of antidepressants: A five-year dataset analysis

Introduction: Depression is an emotional disorder associated with morbidities and disabilities worldwide. The growing use of antidepressants is a concern for health managers because there are still unanswered questions on the effectiveness and safety of these medicines. Drug sales have increased in Brazil in recent years, but investigations on antidepressants sales are not available. We aimed to describe the trends in the antidepressant commerce in Brazil in a five-year period.

Materials and Methods: We performed an ecological study on antidepressant sales in Brazil, from November 2014 to October 2019, using data from IQVIA™, a data provider of pharmaceutical sales. Antidepressants were coded by the Anatomical Therapeutic Chemical classification system, and sales were presented in defined daily doses (DDDs) and DDDs per 1,000 inhabitants per day (DIDs). The results were expressed in absolute quantities and growth rates.

Results: The analyzed dataset contained 23 active substances in 780 products. The total sales of antidepressants increased from 23.3 DIDs in November 2014 to 38.3 DIDs in October 2019 (p = 0.002). Selective serotonin reuptake inhibitors were the most sold category of drugs (+5.7 million DDDs) in the period. ‘Other’ antidepressants presented the largest growth rate (104.7%). Individually, the most sold active substance was escitalopram (+1.8 million DDDs), and vortioxetine had the largest growth rate (336.2%). Tricyclic sales remained unchanged, and monoamine oxidase inhibitors had low and even decreasing sales (−9.5%).

Discussion: The total sales of antidepressants increased in Brazil from November 2014 to October 2019. The higher sale volumes of selective serotonin reuptake inhibitors and higher growth rate of ‘other’ antidepressants, with low sale volume of tricyclics and a decrease of monoamine oxidase inhibitors, suggest the replacement of older drugs by newer ones following a global trend. Therapeutic advances and commercial promotion efforts on new products might explain these findings.

Predictors of common mental disorders and psychiatric medication use among faculty members

PURPOSE

Identify the predictors of common mental disorders (CMD) and psychiatric medication use by faculty members in different teaching units of a public university.

DESIGN AND METHODS

A cross-sectional study on 253 faculty.

FINDINGS

Being single, not having children, and not practicing physical activity were identified as predictors of CMD. Relative to psychiatric medication use, the predictors were the following: being homosexual, teaching classes in the biological sciences field, using medication for the urinary tract and sexual hormones, presenting mental disorder/sleep disorder diagnoses, and being positive for CMD.

PRACTICE IMPLICATIONS

The findings of this study may subsidize more effective interventions aimed toward protecting the health and preventing aggravation in these professionals, as well as measures for promoting changes in the university work context.
