Abstract
A valerian composition includes valerian and an acidifying agent blended together in a pharmaceutically acceptable hydrogel-forming polymer matrix. An expedited release portion of the dosage form includes 5% to 50% of the valerian and is effective to release the valerian therein within 2 hours from placement in a 0.1 N HCl solution. A sustained release portion of the dosage form includes the remainder of the valerian and is effective to release the valerian therein within 10 hours from placement in a phosphate buffer with a pH of 6.8.
