Description
Technical field
The present invention relates to medical technical field, specifically described a kind of composition and method of making the same of moisture insoluble high-activity drug.
Technical background
The molten high-activity drug of shipwreck is meant that in water dissolubility is very little and medicine that its biological activity is very high.Dissolubility is a kind of physical property of medicine, and the 1g medicine can not dissolve fully in 10000ml water and then be poorly water soluble drugs.The biological activity of high-activity drug is very high, and low dose just can produce very strong pharmacological action.
For example, tacrolimus (English name: Tacrolimus), also claim FK506, about 1～2 μ g/ml of the dissolubility in water, oral dose 0.1～0.3mg/kg/ days.Tacrolimus is a kind of macrolide antibiotics with strong immunosuppressive activity, and clinical practice is in the rejection and the autoimmune disease of organ transplantation postoperative, and its effect is renderd a service stronger 10～100 times than ciclosporin.
The solid preparation physical and chemical stability is good, manufacturing cost is lower, take and easy to carry, occupies higher ratio in pharmaceutical preparation.For poorly water soluble drugs, the principal element that how much will become influence, limit drug absorption of the speed of its dissolution rate and stripping quantity.Usually poorly water soluble drugs is made solid dispersion, medicine is dispersed in the carrier of ease of solubility, with molecule or ionic species to improve its absorption and bioavailability.Yet, need in traditional solid dispersion preparation process dried solid dispersion is pulverized, can produce bigger dust.High-activity drug just can produce very strong active force when low dose, for example tacrolimus has strong inhibitive ability of immunity, and the dust that produces in the crushing process is to producers' health and unfavorable.At present on commercial production, generally adopt a large amount of fund inputs to acquire protective device and facility comes strengthen labour protection.Therefore the technology of preparation process efficiently of being badly in need of a kind of environmental protection solves the dust pollution question in the production process, and reduces production costs.
Traditional fluid bed marumerization is mix homogeneously under fluidized state with drug powder and various adjuvant, sprays into binding agent then and granulates, and next step operation, no dust pollution are delivered in dry back discharging.Yet poorly water soluble drugs adopts traditional fluid bed marumerization preparation, and its dissolution can't reach requirement, causes bioavailability poor.High-activity drug is low because of its taking dose, needs to add a large amount of adjuvants and makes suitable dosage form.When the ratio of medicine and adjuvant comparatively during great disparity, it is inhomogeneous to adopt traditional fluid bed preparation method to be easy to cause mixing.Therefore need remedy above-mentioned deficiency in conjunction with new Technology.
Summary of the invention
The objective of the invention is to overcome the dust pollution that the molten high-activity drug of shipwreck produces in the prior art in commercial production, a kind of environmental protection is provided, be fit to the compositions of the moisture insoluble high-activity drug of industrialization.
The invention provides a kind of compositions of moisture insoluble high-activity drug, it can prepare by following method: molten high-activity drug of shipwreck and solid dispersion carrier are dissolved in the organic solvent, adopt fluid bed to make it be sprayed on filler or celphere surface equably, and dry.
Wherein said solid dispersion carrier is one or more in cellulose derivative, surfactant or the high molecular polymer; Wherein cellulose derivative is selected from one or more in hypromellose (HPMC), hyprolose (HPC), methylcellulose (MC) or the ethyl cellulose (EC); Surfactant is poloxamer (Poloxamer), one or more in sodium lauryl sulphate (Sodium Lauryl Sulfate) or the polyoxyethylene stearic acid ester (Polyoxyethylene Stearates); High molecular polymer is one or more in Polyethylene Glycol (PEG), polyvidone (PVP), polyacrylic resin (Eudragit), polyvinyl alcohol (PVA) or the polyoxyethylene (Polyethylene Oxide).Wherein the preferred cellulose derivant is as solid dispersion, particularly hypromellose (HPMC).
Wherein said organic solvent is one or more in methanol, ethanol, acetone, chloroform, dichloromethane, ethyl acetate or the ether.
Wherein said filler is one or more in lactose, starch, sucrose, mannitol or the maltose; Blank micropellets is one or more in cane sugar type medicinal core pellet, starch type medicinal core pellet or the microcrystalline Cellulose type medicinal core pellet, and particle diameter is 20～80 orders.
Wherein the part by weight of molten high-activity drug of shipwreck and solid dispersion carrier is 1: 0.5～1: 10, and medicine layer gain in weight is 0.1%～20%.
The molten high-activity drug of shipwreck all can be with this prepared preparation, such as tacrolimus, letrozole, Anastrozole, lenalidomide, cisapride, teniposide or etoposide etc.
The compositions of the moisture insoluble high-activity drug for preparing, can add acceptable diluent on the pharmacopedics, disintegrating agent, binding agent, lubricant, correctives etc., preparation process routinely, further making oral solid formulation and be used for clinically, and serves as preferred with capsule, tablet or dry suspension.
The present invention also provides a kind of preparation to contain the insoluble high-activity drug method for compositions, its method is: molten high-activity drug of shipwreck and solid dispersion carrier are dissolved in the organic solvent, adopt fluid bed to make it be sprayed on filler or celphere surface equably, and dry.In particular, its preparation method is:
The molten high-activity drug of shipwreck and solid dispersion carrier with the ratio of 1: 0.5～1: 10 weight ratio, are dissolved in an amount of organic solvent;
Said mixture is sprayed on filler or celphere surface in the fluid bed equably, and medicine layer gain in weight is 0.1%～20%;
Directly discharging behind the fluid bed inner drying.
Wherein said solid dispersion carrier is one or more in cellulose derivative, surfactant or the high molecular polymer; Wherein cellulose derivative is selected from one or more in hypromellose (HPMC), hyprolose (HPC), methylcellulose (MC) or the ethyl cellulose (EC); Surfactant is poloxamer (Poloxamer), one or more in sodium lauryl sulphate (Sodium Lauryl Sulfate) or the polyoxyethylene stearic acid ester (Polyoxyethylene Stearates); High molecular polymer is one or more in Polyethylene Glycol (PEG), polyvidone (PVP), polyacrylic resin (Eudragit), polyvinyl alcohol (PVA) or the polyoxyethylene (Polyethylene Oxide).Wherein the preferred cellulose derivant is as solid dispersion, particularly hypromellose (HPMC).
Wherein said organic solvent is one or more in methanol, ethanol, acetone, chloroform, dichloromethane, ethyl acetate or the ether.
