摘要:
The present invention discloses a method of treating a head and neck cancer or preventing the development of pre-malignant lesions to this cancer, by administering locally to the oral cavity, a sustained release drug delivery system comprising a drug for the treatment of this cancer or for the prevention of said lesions, and at least one polymer, such that said system is attached to a surface in the oral cavity and remains attached thereto for at least 1 hour, accompanied by release of the drug and maintaining an effective therapeutic concentration thereof in the cavity, for at least 1 hour. Further are disclosed a sustained release drug delivery system and a liquid precursor varnish composition to this system.
摘要:
The present invention discloses a liquid precursor composition adapted for application on a on a desired surface, this composition comprising : a. at least one therapeutic agent suitable for the treatment or prevention of a disorder or pathological condition, wherein said disorder or pathological condition excludes oral disorders, b. at least one acidic-pH sensitive polymer, c. at least one hydrophobic polymer, and d. a pharmaceutically acceptable volatile solvent, wherein a weight ratio between the at least one hydrophobic polymer and the at least one acidic -pH sensitive polymer is larger than 1.
摘要:
A composition which comprises a biologically active agent and a polymer that exhibits a reverse thermal gelation at a physiological temperature, in a carrier, and in which the active agent is in an undissolved form is disclosed herein. Further disclosed herein are methods utilizing the compositions for treating subjects, including non-human subjects, as well as kits for preparing and using a composition. The composition is preferably a sustained release formulation, and is particularly useful for treating animals, where single-dose treatment is desired.
