Indications & Usage
1 INDICATIONS AND USAGE ISENTRESS® is indicated in combination with other antiretroviral agents for the treatment of human immunodeficiency virus (HIV-1) infection in patients 4 weeks of age and older. The use of other active agents with ISENTRESS is associated with a greater likelihood of treatment response [see Clinical Studies (14) ] . ISENTRESS is a human immunodeficiency virus integrase strand transfer inhibitor (HIV-1 INSTI) indicated: In combination with other antiretroviral agents for the treatment of HIV-1 infection in patients 4 weeks of age and older ( 1 ). The use of other active agents with ISENTRESS is associated with a greater likelihood of treatment response ( 14 ).

During coadministration with rifampin in adults, 800 mg twice daily ( 2.1 ). Children and Adolescents If at least 25 kg: One 400 mg film-coated tablet orally, twice daily. If unable to swallow a tablet, consider the chewable tablet, as specified in Table 1 ( 2.3 ). If at least 3 kg to less than 25 kg: Weight based dosing, as specified in Table 2.

Drug Interactions
7 DRUG INTERACTIONS Coadministration of ISENTRESS and other drugs may alter the plasma concentration of raltegravir. The potential for drug-drug interactions must be considered prior to and during therapy ( 7 ). Coadministration of ISENTRESS with drugs that are strong inducers of UGT1A1, such as rifampin, may result in reduced plasma concentrations of raltegravir ( 2.1 , 7.2 ). 7.1 Effect of Raltegravir on the Pharmacokinetics of Other Agents Raltegravir does not inhibit (IC 50 >100 µM) CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6 or CYP3A in vitro . Moreover, in vitro , raltegravir did not induce CYP1A2, CYP2B6 or CYP3A4. A midazolam drug interaction study confirmed the low propensity of raltegravir to alter the pharmacokinetics of agents metabolized by CYP3A4 in vivo by demonstrating a lack of effect of raltegravir on the pharmacokinetics of midazolam, a sensitive CYP3A4 substrate. Similarly, raltegravir is not an inhibitor (IC 50 >50 µM) of UGT1A1 or UGT2B7, and raltegravir does not inhibit P-glycoprotein-mediated transport. Based on these data, ISENTRESS is not expected to affect the pharmacokinetics of drugs that are substrates of these enzymes or P-glycoprotein (e.g., prot…
Adverse Reactions
6 ADVERSE REACTIONS Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The most common adverse reactions of moderate to severe intensity (≥2%) are insomnia, headache, dizziness, nausea and fatigue ( 6.1 ). Creatine kinase elevations were observed in subjects who received ISENTRESS. Myopathy and rhabdomyolysis have been reported. Use with caution in patients at increased risk of myopathy or rhabdomyolysis, such as patients receiving concomitant medications known to cause these conditions and patients with a history of rhabdomyolysis, myopathy or increased serum creatine kinase ( 6.2 ). To report SUSPECTED ADVERSE REACTIONS, contact Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., Inc., at 1-877-888-4231 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Treatment-Naïve Adults The following safety assessment of ISENTRESS in treatment-naïve subjects is based on the randomized double-blind active controlled study of treatment-naïve subjects…
