Keywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.

Hydroxy progesterone caproate oral preparation and its use
Description
translated from
Technical field
The present invention relates to a kind of oral formulations and purposes of medicine.The oral formulations and the purposes that specifically contain hydroxyprogesterone caproate.
Technical background
Hydroxyprogesterone caproate (Hydroxyprogesterone Caproates) is that China's version pharmacopeia in 2000 is received the standard drug of planting.Indication is the treatment habitual abortion, menoxenia, endometriosis, dysfunctional uterine hemorrhage etc.Dosage form is the oily injection agent, and using method is intramuscular injection, 1-2 time weekly, and each 0.25-0.5g (250mg/ props up).Medicine stores in local deposits after the intramuscular injection, slowly absorb, and the performance long-acting, oil preparation is suitable to above indication.More than remove in addition, bibliographical information the otherwise purposes of hydroxyprogesterone caproate.Cheng Zhao contract quotation road intramuscular injection for treating advanced breast cancer in 1991, inject every day 1 time, each 0.5g, administration time 30 to 519 days (" cancer " 1991.6.491), Zhang Tingmei in 1996 have reported the dyscrasia of the pregnant hydroxyl ketone treatment of intramuscular injection caproic acid patients with advanced cancer, improve patient's quality of life.Inject each 0.5g (" Kweiyang medicine " 1996.2.96) every day.As mentioned above, hydroxyprogesterone caproate is an Oily preparation, and the injection back slowly absorbs, and in the local deposits storage, life-time service easily produces scleroma in the injection site, brings painful and influences to patient and use.To tumour patient is arranged, treatment time reaches several years especially, uses inconvenient.The development oral formulations replaces drug administration by injection to need.
Summary of the invention
The purpose of this invention is to provide the hydroxyprogesterone caproate oral formulations, replace ejection preparation to be used for the disease of existing clinical treatment and the indication of bibliographical information.The research oral formulations will make things convenient for patient's treatment, make oral hydroxyprogesterone caproate become commonly used, convenient, effective and safe drug.The present invention finds that first hydroxyprogesterone caproate oral formulations and injecting drug use have identical drug action, invention is to finish by bioavailability and drug action after the research oral preparation drug administration, thereby it is good to find that oral formulations absorbs, and has blood drug level close with drug administration by injection and pharmacologically actives such as identical antitumor action, the quality of making the life better.Oral administration is easy to use, safe, effective, can replace drug administration by injection.Invention has been carried out the absorption (bioavailability) and the pharmacodynamic study of hydroxyprogesterone caproate by experiment.The research of absorption portion: with the medicament contg in the high-performance liquid chromatogram determination blood plasma.Laboratory animal is mice and Canis familiaris L..The oral formulations of research has tablet, capsule, solution etc.Preparations such as tablet, capsule, solution adopt the conventional method preparation.Mice 0.25,0.5,1,2,4 at lumbar injection and after irritating stomach, 6h get hematometry drug plasma content, Canis familiaris L. intravenous injection and oral after get hematometry drug plasma content.Calculate area under medicine-time graph (AUC) then.(AUC behind the AUC/ drug administration by injection behind the oral administration) * 100%=bioavailability).Oral formulations such as tablet, capsule, solution absorb well at the oral hydroxyprogesterone caproate of mice and Canis familiaris L., and bioavailability reaches 85-90%.The research of drug effect part: compared the tumor-inhibiting action of irritating the harmonization of the stomach lumbar injection at mouse breast cancer EMT, experimental result shows, irritates harmonization of the stomach lumbar injection hydroxyprogesterone caproate the anti-tumor effect of mouse breast cancer basic identical (P＞0.05) has been observed oral administration to improving the effect of patients with advanced cancer life quality at 10 routine patients with advanced cancer.The effect of the therapeutical effect of oral hydroxyprogesterone caproate and bibliographical information drug administration by injection is basic identical.
The specific embodiment
Embodiment 1: assay method high-performance liquid chromatogram determination hydroxyprogesterone caproate, Waters490 chromatograph C18 post is measured wavelength 240nm, mobile phase: methanol: water=85: 15, flow velocity 1ml/ branch, sample introduction 20 μ l, sample disposal: hydroxyprogesterone caproate in the ether extraction blood plasma, interior mark medroxyprogesterone, the response rate 85%, the standard curve range of linearity: 0.1,0.2,0.4,0.8,1.0 μ g,, coefficient R=0.9998.Minimum dfetectable quantity 0.02 μ g.
Embodiment 2: the bioavailability Kunming mouse of hydroxyprogesterone caproate capsule behind mouse stomach, body weight 25-30 gram, per 3 is to get the blood point time, lumbar injection and filling stomach 200mg/kg hydroxyprogesterone caproate, got hematometry hydroxyprogesterone caproate concentration, and calculated area under the drug-time curve (AUC) and bioavailability in 0,0.25,0.5,1,2,4,6 hour after administration.The bioavailability of hydroxyprogesterone caproate capsule behind mouse stomach is 84.8%.
