Reyataz

INDICATIONS

REYATAZ® (atazanavir) is indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection for patients 3 months and older weighing at least 10 kg.

Limitations of Use

  • REYATAZ is not recommended for use in pediatric patients below the age of 3 months due to the risk of kernicterus.
  • Use of REYATAZ/ritonavir in treatment-experienced patients should be guided by the number of baseline primary protease inhibitor resistance substitutions [see Microbiology].

DOSAGE AND ADMINISTRATION

Overview

  • REYATAZ capsules and oral powder must be taken with food.
  • Do not open the capsules.
  • The recommended oral dosage of REYATAZ depends on the treatment history of the patient and the use of other coadministered drugs. When coadministered with H2-receptor antagonists or proton-pump inhibitors, dose separation may be required [see DRUG INTERACTIONS].
  • REYATAZ capsules without ritonavir are not recommended for treatment-experienced adult or pediatric patients with prior virologic failure [see Clinical Studies].
  • REYATAZ oral powder must be taken with ritonavir and is not recommended for use in children who weigh less than 10 kg or who weigh 25 kg or more. [See Dosage And Administration Of REYATAZ Oral Powder In Pediatric Patients]
  • Efficacy and safety of REYATAZ with ritonavir when ritonavir is administered in doses greater than 100 mg once daily have not been established. The use of higher ritonavir doses may alter the safety profile of atazanavir (cardiac effects, hyperbilirubinemia) and, therefore, is not recommended. Prescribers should consult the complete prescribing information for ritonavir when using ritonavir.

Dosage In Adult Patients

Table 1 displays the recommended dosage of REYATAZ capsules in treatment-naive and treatment-experienced adults. Table 1 also displays recommended dosage of REYATAZ and ritonavir when given concomitantly with other antiretroviral drugs and H2-receptor antagonists (H2RA). Ritonavir is required with several REYATAZ dosage regimens (see the ritonavir complete prescribing information about the safe and effective use of ritonavir). The use of REYATAZ in treatment-experienced adult patients without ritonavir is not recommended.

Instructions for Mixing REYATAZ Oral Powder

[see FDA-approved Instructions for Use]

  • It is preferable to mix REYATAZ oral powder with food such as applesauce or yogurt. Mixing REYATAZ oral powder with a beverage (milk, infant formula, or water) may be used for infants who can drink from a cup. For young infants (less than 6 months) who cannot eat solid food or drink from a cup, REYATAZ oral powder should be mixed with infant formula and given using an oral dosing syringe. Administration of REYATAZ and infant formula using an infant bottle is not recommended because full dose may not be delivered.
  • Determine the number of packets (4 or 5 packets) that are needed.
  • Prior to mixing, tap the packet to settle the powder. Use a clean pair of scissors to cut each packet along the dotted line.
  • Mixing with food: Using a spoon, mix the recommended number of REYATAZ oral powder packets with a minimum of one tablespoon of food (such as applesauce or yogurt). Feed the mixture to the infant or young child. Add an additional one tablespoon of food to the small container, mix, and feed the child the residual mixture.
  • Mixing with a beverage such as milk or water in a small drinking cup: Using a spoon, mix the recommended number of REYATAZ oral powder packets with a minimum of 30 mL of the beverage. Have the child drink the mixture. Add an additional 15 mL more of beverage to the drinking cup, mix, and have the child drink the residual mixture. If water is used, food should also be taken at the same time.
  • Mixing with liquid infant formula using an oral dosing syringe and a small medicine cup: Using a spoon, mix the recommended number of REYATAZ oral powder packets with 10 mL of prepared liquid infant formula. Draw up the full amount of the mixture into an oral syringe and administer into either right or left inner cheek of infant. Pour another 10 mL of formula into the medicine cup to rinse off remaining REYATAZ oral powder in cup. Draw up residual mixture into the syringe and administer into either right or left inner cheek of infant.
  • Administer ritonavir immediately following REYATAZ powder administration.
  • Administer the entire dosage of REYATAZ oral powder (mixed in the food or beverage) within one hour of preparation (may leave the mixture at room temperature during this one hour period). Ensure that the patient eats or drinks all the food or beverage that contains the powder. Additional food may be given after consumption of the entire mixture.

Dosage Adjustments In Pregnant Patients

Table 4 includes the recommended dosage of REYATAZ capsules and ritonavir in treatment-naive and treatment-experienced pregnant patients. In these patients, REYATAZ must be administered with ritonavir. There are no dosage adjustments for postpartum patients (see Table 1 for the recommended REYATAZ dosage in adults). [See Use In Specific Populations]

bREYATAZ is not recommended for treatment-experienced pregnant patients during the second and third trimester taking REYATAZ with both tenofovir and H2RA.

Renal Impairment

For patients with renal impairment, including those with severe renal impairment who are not managed with hemodialysis, no dose adjustment is required for REYATAZ. Treatment-naive patients with end stage renal disease managed with hemodialysis should receive REYATAZ 300 mg with ritonavir 100 mg. REYATAZ should not be administered to HIV-treatmentexperienced patients with end stage renal disease managed with hemodialysis. [See Use in Specific Populations]

Dosage Adjustments In Patients With Hepatic Impairment

Table 5 displays the recommended REYATAZ dosage in treatment-naive patients with hepatic impairment. The use of REYATAZ in patients with severe hepatic impairment (Child-Pugh Class C) is not recommended. The coadministration of REYATAZ with ritonavir in patients with any degree of hepatic impairment is not recommended.
