Title: Hiroaki Okutsu: Innovator in Pharmaceutical Patch Technology

Introduction

Hiroaki Okutsu is a prominent inventor based in Tsukuba, Japan. He has made significant contributions to the field of pharmaceutical technology, particularly in the development of innovative patches for drug delivery. With a total of six patents to his name, Okutsu's work focuses on enhancing the efficacy and safety of transdermal drug administration.

Latest Patents

One of Okutsu's latest patents is a method for producing a patch that includes a support layer and an adhesive agent layer. This adhesive layer contains sodium diacetate, a pressure-sensitive adhesive base agent, and asenapine or a pharmaceutically acceptable salt thereof. The method involves generating sodium diacetate from sodium acetate in the presence of asenapine, ensuring that the content of asenapine in the adhesive layer ranges from 3.0 to 20 mg. When the patch is applied to the skin for 24 hours, the concentration of free asenapine is maintained within a specific range, demonstrating the patch's effectiveness in drug delivery.

Another notable patent involves a patch designed for administering asenapine, which also features a support layer and an adhesive agent layer. The adhesive base agent in this patch comprises various materials, including natural rubber and polyisobutylene, with a content range of 10 to 90% by mass. This innovation ensures that when the patch is in contact with the skin, it achieves a significant area under the curve (AUC) for free asenapine, indicating its potential for effective therapeutic outcomes.
