RESUMO
INTRODUCTION: Children living with chronic illnesses are offered formulations based on manufacturer and distributor research. The aim of this study is to better understand the perspectives of children and their caregivers in accepting Lopinavir/ritonavir (LPV/r) formulations. METHODS: 362 participants were recruited from two pediatric HIV/AIDS clinics in Mbeya and Mwanza, Tanzania, from December 2021 to May 2022. A translated questionnaire was piloted and validated at both clinics, followed by the implementation of a cross-sectional study. RESULTS: 169 participants (47.1%) reported general difficulties in swallowing, regardless of formulation, while 34.3% and 38.5% reported vomiting tablets and syrups, respectively. Statistical significance is shown to support that children can swallow medications if they can eat stiffened porridge (Ugali). This correlated with the lower incidence of younger children being able to swallow compared to older children (above six years of age). Children older than six years preferred taking tablets (independent of daily dosage) better than other formulations. Significantly, older children who attend school were associated with high odds of swallowing medicine (AOR = 3.06, 95%CI; 1.32-7.05); however, age was not found to be statistically related to ease of administration for Lopinavir/Ritonavir in this study. CONCLUSIONS: Lopinavir/Ritonavir tablets remain the most accepted formulation among children and adolescents with HIV/AIDS. This study highlights the impact of various factors affecting the acceptability of pediatric formulation, suggesting that children younger than six years, unable to eat Ugali and not attending schools may be most vulnerable regarding their ability to accept Lopinavir/Ritonavir formulations. Further studies are needed to assess the acceptability of other medications in chronically ill children.
