Abstract: A method for enhanced PhotoDynamic Therapy (PDT) treatments by applying dendrimer-photosensitizer complexes to bring multiple phototosensitizer moieties to a treatment site is provided. Photosensitizers are covalently coupled to the peripheral bonding places of dendrimers and are being separated in one or more successive cycles. Tetrapyrroles are the photosensitizers employed. In one embodiment the complex is also bound to an antibody or antibody fragment, which aids in targeting the complex to a desired treatment site. After application, the photosensitizers are released, at the treatment site, from the complexes by either light, chemical, or a combined light/chemical effect. Generally the photosensitizers develop their full photodynamic activity as free molecules after being released from the complex.  More than one type of photosensitizer may be bound in the complexes. Release and/or activation may be done in a single step or with repeated steps.

Abstract: An injectable formulation of a sedative hypnotic drug, such as the anesthetic drug propofol, that is pharmaceutically stable and demonstrates a reduced incidence of pain upon injection. The formulation of the present invention employs a sulfoalkyl ether cyclodextrin solubilizing and complexing excipient, such as CAPTISOL ® cyclodextrin (sulfobutyl ether .beta.-cyclodextrin) to form a true aqueous solution and not a suspension. This formulation minimizes the allergic response and microbial contamination issues typically associated with propofol parenteral formulations. The present formulation may also reduce pain on injection as compared to the known emulsion type propofol formulations. The liquid formulation can be sterile filtered unlike emulsion-type formulations of sedative hypnotics. The liquid formulation can be lyophilized or otherwise dried to yield a solid formulation.
