Polypharmacy in the Management of Arterial Hypertension—Friend or Foe?

Abstract

Background and Objectives: Polypharmacy is associated with drug–drug or food–drug interactions that may pose treatment difficulties. The objective of the study was to investigate the use of polypharmacy in hypertensive patients hospitalized in the Internal Medicine Clinic of a European referral hospital. Materials and Methods: We conducted a retrospective chart review study on patients identified by a database search of discharge diagnoses to assess the use of polypharmacy and identify potential drug-drug and food-drug interactions. Results: In total, 166 hypertensive patients (68.46 ± 12.70 years, range 42–94 years) were compared to 83 normotensive subjects (67.82 ± 14.47 years, range 22–94 years) who were hospitalized in the clinic during the same period. Polypharmacy was more common in hypertensive versus normotensive subjects (p = 0.007). There were no differences in terms of age, as well as major (0.44 ± 0.77 versus 0.37 ± 0.73 interactions/patient, p = 0.52) and minor (1.25 ± 1.50 versus 1.08 ± 1.84 interactions/patient, p = 0.46) drug–drug interactions between patients with and without hypertension. The mean number of drug–drug interactions (6.55 ± 5.82 versus 4.93 ± 5.59 interactions/patient, p = 0.03), moderate drug–drug interactions (4.94 ± 4.75 versus 3.54 ± 4.17, p = 0.02) and food–drug interactions (2.64 ± 1.29 versus 2.02 ± 1.73, p = 0.00) was higher in patients with hypertension versus their counterparts. Conclusions: The present study reinforces that polypharmacy is a serious concern in hypertensive patients, as reflected by the high number of potentially harmful drug–drug or food–drug interactions. We recorded higher numbers of comorbidities, prescribed drugs, and moderate drug–drug/food–drug interactions in hypertensive versus normotensive patients. A strategy to evaluate the number of discharge medications and reduce drug–drug interactions is essential for the safety of hypertensive patients.

Circadian Rhythms, Chrononutrition, Physical Training, and Redox Homeostasis—Molecular Mechanisms in Human Health

“…This compromise is evident at both the cellular and organism levels, and it can precipitate a cascade of adverse consequences. Among these consequences are the emergence and progression of various diseases, including but not limited to cardiovascular syndromes, neurodegenerative disorders, and cancer [4,10,56,[123][124][125][126][127].…”

Potential Interactions Analysis of Antihypertensive Drugs Used in Geriatric

“…The distribution of patients with the potential to experience drug interactions based on comorbidities is generally experienced by patients with comorbidities [23]. Patients with comorbidities need many drugs to treat every disease condition, so the increasing number of prescription drugs can pose a potential risk of drug interactions [24].…”

“…Polypharmacy is often associated with adverse outcomes such as death, adverse drug reactions (ADR), prolonged hospital stays, and increased risk of drug interactions [7][8][9]. Around 3-26% of all ADRs requiring hospitalization are caused by drug interactions [10,11].…”
