Kaletra contains lopinavir and ritonavir, both of which are inhibitors of the P450 isoform CYP3A
in vitro. Co-administration of Kaletra and medicinal products primarily metabolised by CYP3A may
result in increased plasma concentrations of the other medicinal product, which could increase or
prolong its therapeutic and adverse reactions. Kaletra does not inhibit CYP2D6, CYP2C9, CYP2C19,
CYP2E1, CYP2B6 or CYP1A2 at clinically relevant concentrations (see section 4.3).

some medicinal products metabolised by cytochrome P450 enzymes (including CYP2C9 and
CYP2C19) and by glucuronidation. This may result in lowered plasma concentrations and potential
decrease of efficacy of co-administered medicinal products.
