Introduction

Keith A Ellway is a notable inventor based in Washingtonville, NY (US). He has made significant contributions to the field of pharmaceutical delivery systems, holding a total of 4 patents. His work focuses on innovative methods to enhance the delivery and effectiveness of medications.

Latest Patents

Ellway's latest patents include advancements in pulsatile once-a-day delivery systems for minocycline. These pharmaceutical delivery systems utilize 7-dimethyl-6-deoxy-6-demethyltetracycline or its non-toxic acid addition salt. The systems are designed with pH-sensitive polymer-coated spherical granules that release minocycline in a medium with a pH ranging from about 4.0 to about 7.5. Additionally, they include quick-release granules that function in a medium with a pH of less than about 3.9. These formulations ensure that therapeutic blood levels of minocycline are maintained for at least 24 hours with a single daily administration.

Another patent focuses on a similar pulsatile delivery system, which incorporates a minor proportion of slow-release blended polymer-coated granules. This design allows for part of the minocycline to be released in a medium with a pH below 3.9, while the remainder is released in the pH range of 4.0 to 7.5. The systems are effective regardless of whether the patient is fed or fasted, providing enhanced therapeutic blood levels for a full day.
