INTRODUCTION

Arterial hypertension is highly prevalent in people older than 60, two thirds of which are covered in Argentina by the Comprehensive Medical Care Program (PAMI, according to the Spanish acronym). The objective of this work was to estimate the prevalence of antihypertensive drug (AHT) use in older adults of PAMI from the dispensation data and to describe its use in terms of type and quantity.

METHODS

A retrospective observational study was conducted. AHT users were defined as adults of both sexes over 60 years of age who received at least 2 packs of AHT during 2018. The result was compared with the one yielded by the National Risk Factor Survey 2013.

RESULTS

From the 4 397 188 beneficiaries of PAMI who were over 60 (63.8% women; average age: 74.3 years), 48.4% were AHT users during 2018 (women: 49.4%; men: 46.6%). This is similar to the 47.8% recorded in the National Risk Factor Survey 2013. The prevalence of use (PU) increased with age, from 37.5% at 60-64 years to 55.1% at 80-84 years, declining thereafter PU adjusted for age and sex varied from 31.1% in Jujuy to 57.9% in Rio Cuarto. On average, 13.6 packs/user/year were dispensed. The most widely distributed AHTs were angiotensin II receptor antagonists (36.5%), beta blockers (27.0%) and angiotensin converting enzyme inhibitors (23.1%).

DISCUSSION

The analysis of the administrative database of dispensed drugs allows the estimate of epidemiological data and to identify subpopulations that may benefit from specific interventions.
