Insights
Certain medications may impact COVID-19 outcomes. Inhalers, pregabalin, diuretics, and statins were linked to lower mortality or critical care admission, while gliclazide and proton pump inhibitors were associated with increased mortality.
Area of Science:
- Pharmacology
- Infectious Diseases
- Clinical Medicine
Background:
- The drug interactions with coronavirus disease (COVID-19) are largely unknown.
- Understanding medication effects on COVID-19 outcomes is crucial for patient management.
Purpose of the Study:
- To identify common medications associated with altered disease outcomes in patients with COVID-19.
- To analyze the relationship between antecedent prescriptions and COVID-19 severity.
Main Methods:
- Retrospective cohort analysis of adult inpatient admissions with COVID-19.
- Propensity score matching and logistic/linear regression to analyze 42 medications and 22 drug classes.
- Inclusion criteria: medications prescribed to at least 20 patients in the cohort.
Main Results:
- Lower mortality was associated with pregabalin, inhalers (beclomethasone, tiotropium, steroid-containing), diuretics, and statins.
- Increased mortality was linked to gliclazide and proton pump inhibitors.
- Diuretic and statin use correlated with reduced critical care admission rates.
Conclusions:
- Continuing antecedent prescriptions in COVID-19 patients is generally safe without acute contraindications.
- Diuretics, inhalers, pregabalin, and statins show potential as therapeutic agents for COVID-19.
- Further assessment of gliclazide and proton pump inhibitors' safety in acute COVID-19 is warranted.
Abstract:
The interaction of coronavirus disease (COVID-19) with the majority of common prescriptions is broadly unknown. The purpose of this study is to identify medications associated with altered disease outcomes in COVID-19. A retrospective cohort composed of all adult inpatient admissions to our center with COVID-19 was analyzed. Data concerning all antecedent prescriptions were collected and agents brought forward for analysis if prescribed to at least 20 patients in our cohort. Forty-two medications and 22 classes of medication were examined. Groups were propensity score matched and analyzed by logistic and linear regression. The majority of medications did not show a statistically significant relationship with altered disease outcomes. Lower mortality was associated with use of pregabalin (hazard ratio [HR], 0.10; 95% confidence interval [CI], 0.01-0.92; P = .049) and inhalers of any type (HR, 0.33; 95%CI, 0.14-0.80; P = .015), specifically beclomethasone (HR, 0.10; 95%CI, 0.01-0.82; P = .032), tiotropium (HR, 0.07; 95%CI, 0.01-0.83; P = .035), and steroid-containing inhalers (HR, 0.35; 95%CI, 0.15-0.79; P = .013). Gliclazide (HR, 4.37; 95%CI, 1.26-15.18; P = .020) and proton pump inhibitor (HR, 1.72; 95%CI, 1.06-2.79; P = .028) use was associated with greater mortality. Diuretic (HR, 0.07; 95%CI, 0.01-0.37; P = .002) and statin (HR, 0.35; 95%CI, 0.17-0.73; P = .006) use was associated with lower rates of critical care admission. Our data lends confidence to observing usual practice in patients with COVID-19 by continuing antecedent prescriptions in the absence of an alternative acute contraindication. We highlight potential benefits in investigation of diuretics, inhalers, pregabalin, and statins as therapeutic agents for COVID-19 and support further assessment of the safety of gliclazide and proton pump inhibitors in the acute illness.
