Resumo
Lopinavir/ritonavir oral solution contains a large amount of ethanol, and tinidazole can cause a disulfiram-like reaction with alcohol, producing flushing, nausea, vomiting and palpitations. Lopinavir may also raise tinidazole exposure through CYP3A4 inhibition, although the alcohol content is the main concern.
