Abstract: To assess the attitudes and opinions about generic antiretroviral drugs (ARVs) and single-tablet regimen (STR) de-simplification among physicians prescribing HIV treatment in the cohort of the Spanish HIV/AIDS Research Network (CoRIS). An online questionnaire with 27 structured questions was sent to all physicians (n=199) who prescribed ARVs among the 45 centres participating in the cohort. A total of 169 (84.9%) physicians answered the questionnaire. Only 4.1% of the physicians would never prescribe generic ARVs, but 53.3% would not prescribe them if the number of pills per day increased and 89.3% would not prescribe them if the number of doses per day increased. However, 84.0% of the physicians agreed to prescribe generic ARVs if doing so would decrease costs for the public healthcare system. The percentages of physicians stating that generic ARVs (compared with branded ones) would be associated with worse adherence, more adverse effects or more probability of virological failure, provided that the number of pills and doses per day would not change, were low: 0.6%, 7.7% and 3.6%, respectively. However, these percentages were much higher if the generic ARV entailed breaking an STR: 63.9%, 18.9% and 42.0%, respectively. Most physicians stated that they needed more information about the effectiveness and safety of generic ARVs and the price difference compared with their branded equivalents. Although most physicians were confident about prescribing generic ARVs, the majority had strong concerns about de-simplifying STR, and they also needed more information about generic drugs.
