Description
Technical field
The invention belongs to materia medica and galenic pharmacy field, relate to a kind of Emulsion, Preparation Method And The Use that contains the hydrophilic biomacromolecule.
Background technology
Insulin is the hydrophilic biopharmaceutical macromolecular drug of representative, comprising protein or polypeptide, polysaccharide, nucleic acid, be a class medicine that becomes more and more important in the drug world, but a common feature of this class material is, oral administration is invalid, needs frequent drug administration by injection in clinical.Therefore, developing the drug delivery system of a kind of patient's degree of complying with height, suitable oral administration, is the common ideal of the world of medicine.
In decades, research worker adopts strategies such as covalent modification, enzyme inhibitor, absorption enhancer, microcapsules and microsphere parcel, W/O (Water-In-Oil) Emulsion, in the hope of solving the low problem of these hydrophilic biopharmaceutical macromolecular drug oral administration biaavailabilities.Carino?G.P.et?al(2000)J.Control.Release.65：261-269；Kathryn?Wehitehead，et?al(2004)J.Control.Release.98：37-45；Yan?Pan，et?al(2002)Int.J.Pharm?249：139-147；Nerurkar?M.M.et?al(1996)Pharm.Res.13：528-534；Marschutz?M.K.et?al(2000)Biomaterials?21：1499-1507；Christopher?J.H.et?al(1997)Adv.Drug.Deliver.Rev.25：71-89；Jeff?Wang，et?al(2003)J.Control.Release.88：369-380；RogerR.C.New，et?al(1997)Adv.Drug.Del?iver.Rev.25：59-69；AnjaGraf，et?al(2008)Int.J.Pharm.350：351-360；R.NeslihanGursoy?et?al(2004)Biomed.Pharmacother.58：173-182；CN01115327.X，US4849405，US5824638。
But the potential safety hazard of the solution hydrophilic substance oral administration method of above-mentioned routine, for example: covalent modification can reduce pharmaceutically active, and may change pharmacology, the toxicity of drug molecule, brings serious potential safety hazard; The enzyme inhibitor is taken enlargement or the hypertrophy of digesting and assimilating disorder even pancreas with causing for a long time; Absorption enhancer might cell membrane cause irreversible destruction, takes for a long time to cause membrane poisoning.
In addition, the data of having reported at present about the oral administration biaavailability of biomacromolecule are unsatisfactory.Oral insulin microemulsion bioavailability only is 4.44% (Amani Elsayed, et al, European Journal of Pharmaceutics and Biopharmaceutics73 (2009) 269-279); Oral PTH preparation bioavailability only is 2.1% (AndreaLeone-Bay, et al, Pharmaceutical Research, Vol.18, No.7,2001).
Vitamin E claims tocopherol again, is a kind of common fatsoluble vitamin E.When using as antioxidant, concentration is generally less than 1%.Vitamin E also often is used as supplementary, is widely used in fields such as health care, food, medical treatment, beauty treatment.Vitamin E is because of its special structure, to some hydrophobic molecules such as paclitaxel, ciclosporin, steroidal class materials, good dissolubility is arranged, people such as Constantinides in view of the above, outside " water-soluble ", " oil is molten ", the notion (Constantinides, P.P., et al. (2004) Adv DrugDeliv Rev.56:175-82) of " vitamin E is molten " has been proposed again.
With the vitamin E is solvent, is applied to the novel drug administration carrier of hydrophobic molecule, sees people's such as Y.Kato research at first, Xiang Guan research subsequently emerge in an endless stream (Y.Kato, et al. (1993) Chem.Pharm.Bull. (Tokyo) .41:599-604; Constantinides, P.P., et al. (2000) Pharm Res.17:175-82; P.B.Nielsen, et al. (2001) Int.J.Pharm.222:217-24; Constantinides, P.P., et al. (2006) Pharm Res.23:243-55; WO 95/11039; WO97/03651; WO 99/04787; US 6,479, and 540; US 6,458, and 373; US7030155B2).
Vitamin E has the safety of height as food source property material and supplementary, but present research is not seen the report that utilizes vitamin E to realize the oralization administration of hydrophilic biopharmaceutical macromolecular drug as yet only with the carrier of vitamin E as dewatering medicament.
