Laser irradiation of ocular tissues to enhance drug delivery

Ocular Drug Delivery

Traditionally, medication is delivered to the eye by three main mechanisms: Topical ocular administration, systemic administration, and intraocular or periocular injection. Each of these methods has significant disadvantages. Topical ocular solutions or ointments have less than a 1% penetration, have rapid dilution and tear washout, and rely substantially on owner compliance to administer the m...

Hollow Pollen Shells to Enhance Drug Delivery

Pollen grain and spore shells are natural microcapsules designed to protect the genetic material of the plant from external damage. The shell is made up of two layers, the inner layer (intine), made largely of cellulose, and the outer layer (exine), composed mainly of sporopollenin. The relative proportion of each varies according to the plant species. The structure of sporopollenin has not bee...

Drug Design Concept in Ocular Drug Delivery

Ocular administration of the drug is primarily associated with the need to treat ophthalmic diseases and is not regarded as a means for gaining systemic drug action. Major classes of drugs used are miotics, mydriatics/cyclopegics, anti-inflammatory, antiinfectives, surgical adjutants and diagnostics, which are all meant for local therapy. Systemic action by using eye as a portal is generally av...
