INVIRASE in combination with ritonavir and other antiretroviral agents is indicated for the treatment of HIV-1 infection in adults (over the age of 16 years).
The following points should be considered when initiating therapy with INVIRASE:
- The twice daily administration of INVIRASE in combination with ritonavir is supported by safety data from the MaxCmin 1 trial [see ADVERSE REACTIONS] and pharmacokinetic data [see CLINICAL PHARMACOLOGY].
- The efficacy of INVIRASE with ritonavir has not been compared against the efficacy of antiretroviral regimens currently considered standard of care.
- The number of baseline primary protease inhibitor mutations affects the virologic response to INVIRASE/ritonavir.
DOSAGE AND ADMINISTRATION
INVIRASE must be used in combination with ritonavir because ritonavir significantly inhibits saquinavir's metabolism to provide increased plasma saquinavir levels.
Cobicistat is not interchangeable with ritonavir to increase systemic exposure of saquinavir [see WARNINGS AND PRECAUTIONS].
- INVIRASE 1000-mg twice daily (5 x 200-mg capsules or 2 x 500-mg tablets) in combination with ritonavir 100-mg twice daily.
- Ritonavir should be taken at the same time as INVIRASE.
- INVIRASE and ritonavir should be taken within 2 hours after a meal.
- For patients already taking ritonavir 100-mg twice daily as part of their antiretroviral regimen, no additional ritonavir is needed.
- Pediatric dose recommendations that are both reliably effective and below thresholds of concern for QT and PR interval prolongation could not be determined.
Administration For Patients Unable To Swallow Capsules
Open the INVIRASE capsules and place the contents into an empty container. Add 15 mL of either sugar syrup or sorbitol syrup (for patients with Type 1 diabetes or glucose intolerance) OR 3 teaspoons of jam to the contents of INVIRASE capsules that are in the container. Stir with a spoon for 30 to 60 seconds. Administer the full amount prepared for each dose. Suspensions should be at room temperature before administering.
