Polymeric drug delivery system |
| abstract |
This invention describes bioadhesive, erodible, drug delivery vehicles used for delivery of pharmaceutical compounds to the eye and in similar physiological environments. Drug delivery vehicles are composed of a maleic anhydride or lower alkyl maleic anhydride or copolymer homopolymer which incorporates a pharmaceutical compound either in a monolithic form or in a coated form. The bioadhesive, erodible drug delivery vehicles are designed to be retained in the eye after administration and have specific erosion patterns that allow suitable drug delivery rates to be established, at regular intervals per hour, per day or even per week. |
