Darunavir once-daily indication in treatment experienced adults

On 13 December 2010, FDA approved new labeling for darunavir (Prezista) to include a once-daily dosing for treatment-experienced adult patients who have no darunavir-associated resistance mutations.

Darunavir-associated mutations are V11I, V32I, L33F, I47V, I50V, I54L, I54M, T74P, L76V, I84V and L89V.

For patients without darunavir-associated mutations the dose is 800 mg darunavir once daily with ritonavir 100 mg once daily and with food.

For patients with one or more darunavir-associated mutations* the indication remains 600 mg darunavir twice-daily taken with ritonavir 100 mg twice-daily and with food.

Adverse reactions (Section 6.3) was modified to include neutropenia, lipoatrophy, and lipodystrophy under Postmarketing Events in the package inserts.
