Compositions comprising microaggregates containing hydrophobic drugs, as well as methods for their production, are described. Such microaggregates may include micelle structures or combinations thereof with liposomes, and constitute an effective delivery vehicle for a hydrophobic agent. Methods for microaggregate production include the use of preferred lipid compounds and processing conditions favoring the production of small aggregates for improved filter sterilization.

The invention is generally related to the field of formulating medicaments in association with a solid support. Such formulations comprising photosensitizers, and their use in photodynamic therapy, are also provided. Methods for the production of the medicament formulations are also disclosed.
The invention is generally related to the field of photodynamic therapy by use of photosensitizers and stabilized formulations of the photosensitizers. These formulations may be used to deliver a photosensitizer as a pharmaceutical, agricultural, or industrial agent. The photosensitizer containing formulations and compositions of the invention comprise one or more block copolymers. Furthermore, the invention relates to processes for the production of, and application of, said formulations and compositions as photosensitizer drug delivery systems.
An improved method to treat conditions of the eye characterized by ocular neovascularization is provided in which patients are given and initial photodynamic therapy (PDT) treatment to destroy the neovasculature, and then are re-evaluated at least twice during the following 6 months, and retreated as necessary. Preferably, three retreatments are provided.
