Kuvan (saproterin dihydrochloride tablets) is indicated to reduce blood phenylalanine (Phe) levels in patients with hyperphenylalaninemia (HPA) due to tetrahydrobiopterin- (BH4-) responsive Phenylketonuria (PKU). Kuvan (saproterin dihydrochloride tablets) is to be used in conjunction with a Phe-restricted diet.
DOSAGE AND ADMINISTRATION
The recommended starting dose of Kuvan (saproterin dihydrochloride tablets) is 10 mg/kg/day taken once daily.
Response to therapy is determined by change in blood Phe following treatment with Kuvan (saproterin dihydrochloride tablets) at 10 mg/kg/day for a period of up to 1 month. Blood Phe levels should be checked after 1 week of Kuvan (saproterin dihydrochloride tablets) treatment and periodically for up to a month. If blood Phe does not decrease from baseline at 10 mg/kg/day, the dose may be increased to 20 mg/kg/day. Patients whose blood Phe does not decrease after 1 month of treatment at 20 mg/kg/day are non-responders, and treatment with Kuvan (saproterin dihydrochloride tablets) should be discontinued in these patients.
Once responsiveness to Kuvan (saproterin dihydrochloride tablets) has been established, the dosage may be adjusted within the range of 5 to 20 mg/kg/day according to response to therapy. Doses of Kuvan (saproterin dihydrochloride tablets) above 20 mg/kg/day have not been evaluated in clinical trials.
Kuvan (sapropterin dihydrochloride) Tablets should be administered orally with food to increase absorption, preferably at the same time each day. Kuvan (saproterin dihydrochloride tablets) Tablets should be dissolved in 4 to 8 oz. (120 to 240 mL) of water or apple juice and taken within 15 minutes of dissolution. It may take a few minutes for the tablets to dissolve. To make the tablets dissolve faster, stir or crush them. The tablets may not dissolve completely. Patients may see small pieces floating on top of the water or apple juice. This is normal and safe for patients to swallow. If after drinking the medicine patients still see pieces of the tablet, they can add more water or apple juice to make sure that they take all of the medicine. A missed dose should be taken as soon as possible, but 2 doses should not be taken on the same day.
