MACHADO ALBA, Jorge Enrique; MORALES PLAZA, Cristhian David  e  HOYOS SOTO, Valentina. Frequency of risk potential drug interactions between antiretrovirals and other drugs in Colombian patients. Investig. andina [online]. 2014, vol.16, n.28, pp.910-920. ISSN 0124-8146.

Objectiv: determine the prevalence of potential risk drug interactions between antiretroviral and other drugs in Colombian patients with HIV/AIDS. Materials and methods: cross-sectional study who took the prescription drugs a population database of 6.2 million users from May 1 to July 31, 2012. To identify potential interactions, we sought dispensing antiretrovirals: Nucleoside Reverse Transcriptase Inhibitors, Non-Nucleoside Inhibitors of Reverse Transcriptase (NNRTIs), Protease Inhibitors (PIs), integrase inhibitors, CCR5 antagonists and fusion inhibitors with other risk drugs because their ineffectiveness or toxicity. Analysis by SPSS 21.0. Results: 968 patients were obtained, mostly men (n = 844, 87.2%), mean age 41.6±10.5 years (range: 3-75 years) and male:female ratio of 5.8:1, from 25 cities. In total we found 49 associations of risk; the IPs being involved in 40 cases. The most common interaction was between IPs and statins (OR: 29.5, 95%CI:14,837-58, 785, p <0.001), IPs and antidepressants (OR: 29.5, 95%CI:11,891-73, 266, p <0.001), and corticosteroids (OR: 15.5, 95%CI:4,938-49, 698, p<0.001) and between NNRTIs with warfarin (OR: 46.3, 95% CI :4,108-520, 764, p<0.001). Receive ritonavir became an potential risk factor interactions (OR: 6.7, 95% IC:3.562-12.934; p<0.001) between people living in the Manizales with other places (OR: 3.7, 95%IC:1.043-12.909; p=0.030). Conclusions: the potential interactions between antiretrovirals and other drug groups are common. It is imperative prior assessment and continuous monitoring patients undergoing risk. We recommend similar strategies to those of the current work to strengthen pharmacovigilance programs.
