摘要:
The invention relates to pharmaceutical compositions suitable for parenteral administration comprising, peptides in the form of acetate, gluconate, glucuronate, lactate, citrate, ascorbate, benzoate or phosphate salts in dissolved or dispersed form and at least one of the acids for forming the salts in free acid form.
摘要:
Peptides which include unnatural amino acids and which either promote or inhibit the secretion of gonadotropins by the pituitary gland and inhibit the release of steroids by the gonads. Administration of an effective amount of such peptides that are GnRH antagonists prevents ovulation of female mammalian eggs and/or the release of steroids by the gonads and may be used to treat steroid-dependent tumors. The agonists can be used for control of reproduction processes, to treat precocious puberty, endometriosis, and the like. The peptides are analogs of the decapeptide GnRH wherein there is at least one residue of an unnatural amino acid in the 3-, 5-, 6- and/or 8-positions. Unnatural amino acids having the following formula are incorporated in a preferred group of synthesized peptides:
摘要:
The present invention relates to the treatment of dementia and neurodegenerative diseases like Alzheimer's disease with intermediate doses of LHRH antagonists which do not cause a castration. A preferred LHRH antagonist is cetrorelix.
摘要:
A novel lyophilizate and method of preparation as well as the use of the lyophilizate to treat female infertility and for gonad protection. Cetrorelix is dissolved in acetic acid 30% v/v, the solution is transferred to water and freeze dried.
摘要:
A composition for enteral administration having a non-ionic vegetable oil GIT absorption enhancer capable of increasing the enteral absorbability of drugs, especially oral absorbability of hydrophilic and macromolecular drugs. The non-ionic vegetable oil GIT absorption enhancer, particularly Babassu oil or a derivative thereof, is capable of enhancing the uptake of a drug from the gastrointestinal tract so as to allow therapeutically effective amounts of the drug to be transported across the GIT of an animal such as a human without significant toxic side effects.
摘要:
The invention relates to pharmaceutical administration forms suitable for parenteral administration, which contains nullsicnull peptides prone to aggregation in the form of their acetate, gluconate, glucuronate, lactate, citrate, ascorbate, benzoate or phosphate salts in dissolved or dispersed form and additionally comprises nullsicnull one of the acids mentioned as free acid.
摘要:
Peptides are provided which have improved duration of GnRH antagonistic properties. These antagonists may be used to regulate fertility and to treat steroid-dependent tumors and for other short-term and long-term treatment indications. These antagonists have a derivative of aminoPhe or its equivalent in the 5- or the 5- and 6-positions. This derivative is modified so as to contain a carbamoyl group or heterocycle, including a urea moiety, in its side chain. Decapeptides having the formula: Ac-D-2Nal-D-4Cpa-D-3Pal-Ser-4Aph(L-hydroorotyl)-D-4Amf(Q2)-Leu-Lys(isopropyl)-Pro-Xaa10, wherein Q2 is Cbm or MeCbm and Xaa10 is D-Ala-ol or Ala-ol are particularly effective and continue to exhibit very substantial suppression of LH secretion at 96 hours following injection.
摘要:
Sustained delivery formulations comprising a water-insoluble complex of a peptidic compound (e.g., a peptide, polypeptide, protein, peptidomimetic or the like) and a carrier macromolecule are disclosed. The formulations of the invention allow for loading of high concentrations of peptidic compound in a small volume and for delivery of a pharmaceutically active peptidic compound for prolonged periods, e.g., one month, after administration of the complex. The complexes of the invention can be milled or crushed to a fine powder. In powdered form, the complexes form stable aqueous suspensions and dispersions, suitable for injection. In a preferred embodiment, the peptidic compound of the complex is an LHRH analogue, preferably an LHRH antagonist, and the carrier macromolecule is an anionic polymer, preferably carboxymethylcellulose. Methods of making the complexes of the invention, and methods of using LHRH-analogue-containing complexes to treat conditions treatable with an LHRH analogue, are also disclosed.
摘要:
Immunogenic compositions capable of generating an immune response in mammals against GnRH are disclosed. The immunogenic compositions are effective in methods of treating gonadotropin and gonadal steroid hormone dependent diseases and immunological contraception of mammals.
