| 摘要 |
A bioactive dose for delivering a bioactive agent to a mammal, includes a solid bioactive dosage unit containing at least one bioactive agent and a rapid release coating provided on at least one outer surface of the solid bioactive dosage unit, the rapid release coating containing a material having a property of rapidly modulating a pH of bodily fluids in which the material comes in contact in a direction towards an ideal absorptive pH or towards an ideal pH to hinder absorption of the at least one bioactive agent given the pKa that least at one bioactive agent. A modified liquid that is administered prior to, contemporaneous with, or following the delivery of a bioactive agent is also described. The liquid includes a pH modifier selected to control the pH of the liquid to a predetermined range so that the modified liquid rapidly modulates the pH of bodily fluids to enhance or hinder absorption of the bioactive agent. |
