Hybrid Dendrimer Hydrogel/Poly(lactic-Co-glycolic acid) Nanoparticle Platform: An Advanced Vehicle for Topical Delivery of Antiglaucoma Drugs and a Likely Solution to Improving Compliance and Adherence in Glaucoma Management
Glaucoma therapy typically begins with topical medications, of which there are 4 major classes in common use in the United States: beta-Adrenergic antagonists, alpha-Agonists, carbonic anhydrase inhibitors, and prostaglandin analogs. Unfortunately, all 4 classes require at least daily dosing, and 3 of the 4 classes are approved to be administered 2 or 3 times daily. This need for frequent dosing with multiple medications makes compliance difficult. Longer-Acting formulations and combinations that require less frequent administration might improve compliance and therefore medication effectiveness. Recently, we developed an ocular drug delivery system, a hybrid dendrimer hydrogel/poly(lactic-co-glycolic acid) nanoparticle platform for delivering glaucoma therapeutics topically. This platform is designed to deliver glaucoma drugs to the eye efficiently and release the drug in a slow fashion. Furthermore, this delivery platform is designed to be compatible with many of the glaucoma drugs that are currently approved for use. In this article, we review this new delivery system with in-depth discussion of its structural features, properties, and preclinical application in glaucoma treatment. In addition, future directions and translational efforts for marketing this technology are elaborated.
