  • Patent number: 9034914
    Abstract: The present invention relates to new salts of 6-(propyl-(2-thiophen-2-ylethyl)amino)tetralin-1-ol(rotigotine), their use as a medicament, for example for the treatment of CNS disorders like Parkinson Disease, RLS, fibromyalgia and/or depression, in particular through electromotive administration. The present invention relates to pharmaceutical formulations suitable for iontophoresis that provide enhanced iontophoretic delivery of rotigotine to at least one target tissue. The formulations are further characterized by good to excellent solubility of the salts in aqueous solutions.
    Type: Grant

  • Patent number: 7632859
    Abstract: By using a composition comprising rotigotine and at least one chloride salt in a concentration of 1 to 140 mmol/l, the composition having a pH of 4 to 6.5 in a iontophoretic device for the treatment of Parkinson's disease, it became possible to obtain a rotigotine flux across the human stratum corneum which was higher than the one previously obtained with conventional passive diffusion systems.

  • Patent number: 6284754
    Abstract: The invention relates to pharmaceutical compositions for topical application containing at least one physiologically active agent and an effective amount of 1-oleylazacycloheptan-2-one as the human or animal epithelial membrane permeability enhancer, to the application of such pharmaceutical compositions by means of locally contacting the skin or other membrane of the human or animal with the above composition and to the 1-oleylazacycloheptan-2-one compound per se.

  • Patent number: 5830499
    Abstract: Phospholipid- and cholesterol-free aqueous compositions for topical application to the skin contain a pharmaceutically active ingredient and a vector system of controlled and in-depth transport and release of the active ingredient through the skin. The vector system comprises at least one first non-ionic surfactant which forms vesicles upon dispersion in water and a lamellar phase upon concentrating the vesicles, and at least one second non-ionic hydrophilic surfactant. The ratios of the two non-ionic surfactants are such that the vector system comprises flexible vesicles.
