Abstract
A progesterone-semi-solid skeleton composition for treating the diseases caused by deficiency of progestin and disfunction of corpus luteum contains progesterone (0.5-10 wt.%), surfactant (1-98.5 wt.%) and semi-solid skeleton carrier (1-98.5 wt%.). Its advantages are high biological utilization rate and low dosage.
Description
Technical field
The present invention relates to a kind of progesterone preparation.
Background technology
Progesterone, its English Progesterone by name, its chemistry pregnant steroid by name-4-alkene-3, the 20-diketone, its structural formula is as follows:
Molecular formula: C
21H
30O
2, molecular weight: 314.47.
Progesterone can significantly increase progestogen concentration in the blood, has the general action of progestogen.It acts on endometrium, can make the caused propagation phase of estrogen be converted into the secretory phase, for implantation of ovum and early stage embryo's nutrition provides advantage and keeps gestation.Improve various symptoms and disease that for want of progestogen or inadequate luteal function caused:
(1) cures mainly premenstrual syndrome and the miscarriage that luteal phase defect causes.
(2) because withdrawal bleeding is carried out in dysfunctional uterine hemorrhage due to the anovulation or amenorrhea etc.
(3) replenish the various diseases that CLI causes.
(4) use of the effect of the simple estrogen of antagonism with the estrogen cycle to inner membrance.
In addition, Progesterone also is used to improve the pregnancy rate of animal in veterinary drug.
But the Progesterone water solublity is very poor, oral post-absorption amount is few and very fast by the liver metabolism inactivation, therefore the dosage form of using clinically is injection, and is very inconvenient to patient especially life-time service person, and easily causes medicine to deposit partial musculature and cause lump pain etc.
In view of above situation, France has developed the oral micropowder soft gelatin capsule UTROGESTAN (Utrogestan) that gone on the market and has replaced injection.The Utrogestan soft gelatin capsule has improved the oral bioavailability of Progesterone to a certain extent, but costs an arm and a leg, and 8 yuan every, listing at home.Therefore, still there is not very good progesterone preparation at present.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of Progesterone semi-solid backbone type preparation (Semi Solid Matrix), promptly in medicinal liquid, add material with wax shape fusing point sample, energy hot melt when high temperature, it during room temperature solid, compare with traditional powder particle filling, it can avoid drug powder to fly upward (being particularly useful for hormone and anticarcinogen); Loadings is even, and principal agent dosage is accurate; Medicine or medicinal liquid are scattered in the excipient isolated with air and dampness, thereby more stable; Suitably adjust prescription, can obtain desired high bioavailability, in the hope of making pharmacological active substance Progesterone absorption in vivo better, the curative effect that obtains under lower dosage also reduces untoward reaction.
Preparation of the present invention comprises:
Progesterone 0.5~10% (weight)
The surfactant 1~98.5% (weight) of HLB (hydrophile-lipophile balance value) more than 12
The carrier 1~98.5% (weight) of semi-solid backbone
The surfactant that meets above-mentioned condition comprises the polyoxyethylene castor oil double glyceride, polyoxyethylene 6 sorbitan mono-laurates sorbitan fatty acid esters (span) such as (span 20s), polyoxyethylene mono laurate Pyrusussuriensis ester, polyoxyethylene fatty acid Pyrusussuriensis esters (tween) such as polyoxyethylene list oleic acid Pyrusussuriensis ester, polyoxyethylene alkyl ethers such as Brij30, cithrols such as polyoxyethylene 10 monolaurates, polyoxyethylene castor oil, certain herbaceous plants with big flowers acid glyceryl laurate ester, mixed fatty glycerides such as caproic acid glyceryl laurate ester, the sad capric acid polyethyleneglycol glyceride and the mixture of two or more compositions in them.
The carrier of used semi-solid backbone comprises one or more in Polyethylene Glycol, Myrj 52, poloxamer, polyoxyethylene sorbitan monostearate, 12~18 carbon fatty acid glyceride or propylene glycol stearate, the lauric acid polyethyleneglycol glyceride among the present invention.
The main effect of said surfactant is the hydrophilic that increases Progesterone, promotes its absorption in vivo, and its hydrophile-lipophile balance value HLB value is big more, and its hydrophilic is also big more, and effect is also just stronger.
So surfactant can increase the dissolubility of insoluble drug in water, be commonly considered as because surfactant forms micelle (micelle) result (Micelles) in water.Micelle is inwardly to form a minimum oil droplet (nonpolar center) by the lipophilic group of surfactant, hydrophilic group then outside (hydrophilic group of nonionic then from oil droplets as wavy to around stretch into aqueous phase) form spheroid.
Think that now micelle can insert solubilizate such as Progesterone in the oil droplet in the micelle with the nonpolar part of its molecule with polar molecule slightly, its polarity part then stretches between the hydrophilic group of the surfactant in the water and produces solubilization.
Surfactant has the effect of lipin dissolving when low concentration, can dissolve the phospholipid of gastrointestinal mucosal and change epithelial permeability, reduces the barrier action of intestinal mucosa lipoid.So many medicines that originally were difficult to absorb, add surfactant and make to absorb and increase by passive diffusion.Therefore the agent of HLB value higher surface activity can increase the dissolubility of Progesterone in water, can reduce the barrier action of intestinal mucosa lipoid again and increases its absorption in vivo.
Said semi-solid backbone carrier with substrate with certain HLB value for well, it has water solublity on the one hand, can be as the semisolid dispersion of poorly water soluble drugs, and certain liposoluble performance is arranged again, with can also form low-melting fused matter after Progesterone mixes, increase the medicine absorption in vivo.
Preparation of the present invention is preparation like this:
Each composition is quantitatively mixed according to the above ratio, stir, heating to make that preparation is easier to be carried out, and can be made into capsule with capsule liquid-filling machine (modular system is arranged) abroad, and also available miscellaneous equipment is made drop pill, powder etc.
Stability to the Progesterone semi-solid skeleton preparation that makes of the present invention is investigated:
This product is removed outer package directly exposed under illumination 4500LX, 40 ℃, 25 ℃ RH92.5% conditions each 10 days, carry out character, content color and luster, cracked property, dissolution, mensuration content, chromatograph inspection catabolite with the primary sample contrast, all basicly stable.
This product is under the listing terms of packing (mould bottled, aluminum plastic film seals), and room temperature was placed 6 months and 40 ℃ of RH75% conditions were quickened 6 months, and regularly investigated index observing mensuration by the quality standard of working out, and every index is all basicly stable.
