(dexmethylphenidate hydrochloride) Extended-release Capsules
Focalin XR should be given cautiously to patients with a history of drug dependence or alcoholism. Chronic abusive use can lead to marked tolerance and psychological dependence with varying degrees of abnormal behavior. Frank psychotic episodes can occur, especially with parenteral abuse. Careful supervision is required during withdrawal from abusive use, since severe depression may occur. Withdrawal following chronic therapeutic use may unmask symptoms of the underlying disorder that may require follow-up.
Focalin XR is an extended-release formulation of dexmethylphenidate with a bi-modal release profile. Focalin XR uses the proprietary SODAS® (Spheroidal Oral Drug Absorption System) technology. Each bead-filled Focalin XR capsule contains half the dose as immediate-release beads and half as enteric-coated, delayed-release beads, thus providing an immediate release of dexmethylphenidate and a second delayed release of dexmethylphenidate. Focalin XR is available as 5, 10, 15, 20, 25, 30, 35, and 40 mg extended-release capsules. Focalin XR 5, 10, 15, 20, 25, 30, 35, and 40 mg extended-release capsules provide in a single dose the same amount of dexmethylphenidate as dosages of 2.5, 5, 7.5, 10, 12.5, 15, 17.5, or 20 mg of Focalin given b.i.d. as tablets.
