Development of a conjunctival contact-type drug delivery device for latanoprost using hyaluronic acid.

ABSTRACT: Effective topical drug delivery is crucial for glaucoma treatment, necessitating more convenient methods to enhance patient compliance. This study evaluates the efficacy and safety of using freeze-dried hyaluronic acid (HA) as a carrier for a novel conjunctival-contact drug delivery system. We developed HA tablets loaded with latanoprost (HA-latanoprost) and verified the concentration using high-performance liquid chromatography. Twenty mice (C57BL6) were divided into four groups (n = 5 per group): normal saline (group 1), control HA tablet (group 2), Xalatan™ (group 3), and HA-latanoprost tablet (group 4). Treatments were administered to the right eyes, with the left eyes serving as no-treatment controls. Intraocular pressure (IOP) and irritation (measured by scratching motions) we
