Definitions
- the present invention relates to pharmaceutical formulations with analgesic activity containing as active ingredient polypeptides obtainable by extraction of mammal liver, particularly goat liver, with perchloric acid.
- polypeptides which can be used according to the invention are disclosed in EP 574 394 as potent antineoplastic agents.
- EP 574 394 the effectiveness of said polypeptides in controlling tumor-related pain is described.
- compositions of the invention will preferably contain the goat liver extract defined in EP 574 394 with the abbreviation L6E, essentially consisting of three main protein components with molecular weights of 50,000, 14,000 and 10,000 daltons in SDS-PA6E, or the single protein components with molecular weights of 50,000 and/or 14,000 and/or 10,000.
- compositions will be preferably administered by the parenteral route, for example intramuscularly or subcutaneously, in the form of sterile solutions or suspensions.
- parenteral route for example intramuscularly or subcutaneously
- examples of said formulations comprise vials or ampoules containing the freeze-dried ingredient to be dissolved before use with physiological sterile solutions, solutions or suspensions in sterile aqueous or oily solvents suitable to the in vivo administration.
- the daily dosage, related to the LGE extract will typically range from 0.1 to 20 mg of extract (or the equivalent of the components thereof) .
- the central analgesic activity is particularly fast and it is not accompanied by tolerance and/or addiction phenomena.
- Analgesic thresholds were evaluated using the hot plate test (56*C). LGE was administered subcutaneously to normal Sprague Dawley rats (Charles River, Calco, CO) at the doses reported in the table.
- the hot plate test evidences a "central" analgesic effect.
