<H1>Ritalin LA</H1><P> Ritalin LA (methylphenidate hydrochloride) extended-release capsules is an extended-release
formulation of methylphenidate with a bi-modal release profile. Ritalin LA uses the proprietary
SODAS (Spheroidal Oral Drug Absorption System) technology. Each bead-filled Ritalin LA capsule
contains half the dose as immediate-release beads and half as enteric-coated, delayed-release beads,
thus providing an immediate release of methylphenidate and a second delayed release of
methylphenidate. Ritalin LA 10, 20, 30, and 40 mg capsules provide in a single dose the same amount
of methylphenidate as dosages of 5, 10, 15, or 20 mg of Ritalin.</P>
