Description of intervention(s) / exposure
Treatment: Drugs - maraviroc

Experimental: 1 -


Treatment: Drugs: maraviroc
The nominal dose for maraviroc is 300 mg twice a day (BID). However, the dosage of maraviroc should be adjusted based on optimal background therapy (OBT) patient is taking. If OBT includes CYP3A4 inhibitor (with or without inducers) maraviroc dose should be 150 mg BID and if OBT includes CYP3A4 inducer (without inhibitors) maraviroc dose should be 600mg BID. If OBT does not include any CYP3A4 inducers or inhibitors maraviroc dose should be 300 mg BID.
