NAPDAS™ 500 Controlled Release Tablets: Each Controlled Release Tablet contains Naproxen Sodium USP equivalent to Naproxen 500 mg.
NAPDAs™ is the preparation of naproxen sodium, a member of the arylacetic acid group of nonsteroidal anti-inflammatory drugs (NSAIDs). NAPDAs™ tablets use the proprietary IPDAS* (Intestinal Protective Drug Absorption System) technology*. It is a rapidly disintegrating tablet system combining an immediate release component and a sustained release component of microparticles that are widely dispersed, allowing absorption of the active ingredient throughout the gastrointestinal (Gl) tract, maintaining blood levels over 24 hours. After oral administration, plasma levels of naproxen are detected within 30 minutes of dosing, with peak plasma levels occurring at approximately 5 hours after dosing.
