Abstract
BACKGROUND: We would like to raise awareness about the toxicities related to the added excipients present in the oral solution of Liponavir/ritonavir in particular alcohol and propylene glycol. CASE PRESENTATION: In this case report, we describe an 18 month-old child with a newly diagnosed HIV infection on antiretroviral therapy (ART). She developed shortly after starting the ART unsteady gait and imbalance. CONCLUSIONS: The excipient-excipient interaction in Lopinavir/ritonavir may contribute to major toxicities not only in premature neonates and infants; but also in older children specifically from Asian ethnicity.
