METHOD OF PROVIDING CUSTOMIZED DRUG DELIVERY CORRELATING TO A PATIENT’S METABOLIC PROFILE

摘要

A novel method of correlating the disposition of a specific drug in an individual patient to a controlled and modulated delivery system for optimizing therapeutic response of orally ingested dosage forms is provided. Such a method broadly encompasses a first determination of an individual's metabolic rate in terms of absorption of pharmaceutical materials from within the gastrointestinal tract measured as blood plasma concentration over a specific period of time after ingestion or by other commercially available methods and subsequent determination: 1) predicting a proper pharmaceutical compositions, in terms of amount of active available for absorption by the target patient; and 2) amount of such active pharmaceutical ingredient (API) to be formulated within a drug-delivery device that will take into account the unique metabolic profile of the drug (or drugs) in a specific patient. As a result, the API may be formulated as beads, pellets, minitablets, powders, granules, suspensions, and/or emulsions present within the drug-delivery source. As one potentially preferred embodiment, such beads and/or pellets, which may be coated with different polymers and differing levels of coatings, are selected in response to the initial determination of the patient's metabolic profile in order to ensure the specific targeted patient receives the most efficient dosage of the active drug at a rate unique to that individual.
