Hispidulin-rich fraction of Clerodendrum fragrans Wild. (Sesewanua) dissolving microneedle as antithrombosis candidate: A proof of concept study.

Existing conventional antithrombosis drugs have caused many side effects, opening up opportunities for the development of new thrombotic drugs. There is potential to use the hispidulin-rich fraction of sesewanua (HRFS) as a new antithrombotic. The oral route limitation of hispidulin, as a low water solubility and non-polar compound, can be addressed. This study explores the potential of HRFS in the form of dissolving microneedles (DMN). The formula was created using polymers such as polyvinyl alcohol (PVA), polyvinyl pyrrolidone K-30 (PVP), and non-ionic surfactant. Ex vivo permeation studies found that 184.95 µg/cm
