Prevalencia de potenciales interacciones farmacológicas de Azitromicina en Colombia, 2012-2013

Abstract

Objective To determine the prevalence of potential drug interactions between azithromycin and different IA and III antiarrhythmic groups in a national database of drug prescriptions in 2012-2013. Methods Retrospective study based on a population database of medicine dispensation. Data from patients who received azithromycin between January 1, 2012 and June 30, 2013 were extracted along with data from patients who received azithromycin in combination with other medications shown to cause heart arrhythmias when used concomitantly. Frequencies and proportions were established. Results 13 859 patients receiving azithromycin alone or in combination with other drugs were identified. The average time of use was 4.5 ± 0.9 days. A total of 702 patients (5.1 %) received azithromycin plus 19 other potentially risky drugs. The most frequently associated were loratadine (77.1 %), diphenhydramine (16.5 %) and amitriptyline (8.1 %). Combinations with a single drug were the most frequent (n=533, 75.9 %), predominantly azithromycin+loratadine. The maximum number of combined drugs was six (n=2, 0.3 %). Conclusions Identification of drug prescriptions through population databases is an effective way to find potential drug interactions. The frequency of potential interactions between azithromycin and other drugs is common in Colombian patients. Future research should assess the risk of occurrence of adverse cardiac events.

“…Among these, 351 articles were excluded after title screening and the abstract of the 784 remaining papers was assessed. Finally, 461 publications were excluded following the eligibility criteria and thus, 323 articles that had interpretable data and fulfilled the eligibility criteria were used for data extraction…”

“…A pharmacy dispensing company (Audifarma SA) was identified in the SLR as the most commonly used database for RWE 34,42,61,63,72,73,94‐98,100‐109,111‐115,117,118,120,122‐131,134‐141,163,168,242,301,310 . It contains demographic data, diagnosis by ICD‐10, and drug dispensation records coded by the Anatomical Therapeutic Chemical (ATC) classification, which can be used to identify comorbidities, drug‐to‐drug interactions, medication errors, adverse events, and calculate adherence rates.…”

“…O terceiro, ciprofloxacino, é uma fluorquinolona bactericida por meio da inibição das enzimas topoisomerases bacterianas (tipos II e IV) (1,2). O quarto, azitromicina, é um macrolídeo inibidor da síntese de proteínas bacterianas, utilizado no tratamento das infecções bacterianas do trato respirató-rio, e também nas infecções da pele e dos tecidos moles (19,20). Todos os antimicrobianos citados apresentam amplo espectro de ação principalmente contra bactérias aeróbias (1,2,(17)(18)(19)(20).…”
