Abstract: The present invention is directed to a method of synthesizing a compound of Formula I: the method comprising oxidizing alpha-tocopherol with a metal salt oxidizing agent to form the compound of Formula I, wherein the stoichiometric ratio (mol/mol) of metal salt oxidizing agent/alpha-tocopherol is 1.6 to 4. The invention is also directed to a method of synthesizing a compound of Formula I, the method comprising (a) hydrolyzing alpha-tocopheryl acetate in the presence of a base; (b) neutralizing the hydrolyzing of (a), thereby forming alpha-tocopherol; and (c) oxidizing the alpha-tocopherol of (b) with a metal salt oxidizing agent to form the compound of Formula I, wherein the stoichiometric ratio (mol/mol) of metal salt oxidizing agent/alpha-tocopherol is 1.6 to 4.

Abstract: A chronotherapeutic pharmaceutical formulation comprising a core containing an active agent (e.g., a drug) and a surfactant and a delayed release compression coating comprising a natural or synthetic gum applied onto the surface of the core.

Abstract: Robust sustained release formulations, solid dosage forms comprising robust sustained release formulations, and methods for making and using these formulations and solid dosage forms are provided. Robustness of the sustained release formulation is related to the particle size of the hydrophilic gum. Sustained release formulations resist dose-dumping when ingested with alcohol. The formulations are useful for treating a patient suffering from a condition, e.g., pain. The formulations comprise at least one drug. In one embodiment, the drug is an opioid, e.g., oxymorphone.
