英国药典2011Prolonged-release Tamsulosin CapsulesGeneral NoticesProlonged-release Tamsulosin Capsules from different manufacturers, whilst complying with the requirements of the monograph, are not interchangeable unless otherwise justified and authorised.DEFINITIONProlonged-release Tamsulosin Capsules contain Tamsulosin Hydrochloride. They are formulated so that the medicament is released over a period of several hours.PRODUCTIONA suitable dissolution test is carried out to demonstrate the appropriate release of Tamsulosin Hydrochloride. The dissolution profile reflects the in vivo performance which in turn is compatible with the dosage schedule recommended by the manufacturer.The capsules comply with the requirements stated under Capsules and with the following requirements.Content of tamsulosin hydrochloride, C20H28N2O5S,HCl95.0 to 105.0% of the stated amount.IDENTIFICATIONA. In the Assay, the principal peak in the chromatogram obtained with solution (1) has the same retention time as that in the chromatogram obtained with solution (2).B. The light absorption of solution (1) obtained in the Assay, Appendix II B in the range 210 to 400 nm, exhibits a single maximum at 225 nm.TESTSRelated substance sCarry out the method for liquid chromatography, Appendix III D, using the following solutions.(1) Mix for at least 15 minutes with the aid of ultrasound and with intermittent shaking a quantity of the capsules containing 0.8 mg of Tamsulosin Hydrochloride with 10 ml of 1M methanolic hydrochloric acid and filter through a 0.7-µm glass fibre filter, to 1 volume of the filtrate add 4 volumes of 1M methanolic hydrochloric acid and filter through a 0.7-µm glass fibre filter.(2) Dilute 1 volume of solution (1) to 500 volumes with mobile phase.(3) 0.00032% w/v of tamsulosin hydrochloride impurity standard BPCRS in the mobile phase.(4) Dilute 1 volume of solution (2) to 4 volumes with mobile phase.CHROMATOGRAPHIC CONDITIONS(a) Use a stainless steel column (15 cm × 4.6 mm) packed with octadecylsilyl silica gel for chromatography (5 µm) (Nucleosil C18 100Å is suitable).(b) Use isocratic elution and the mobile phase described below.(c) Use a flow rate of 1.5 ml per minute.(d) Use a column temperature of 40°.(e) Use a detection wavelength of 225 nm.(f) Inject 20 µl of each solution.(g) Allow the chromatography to proceed for 40 minutes.MOBILE PHASE300 volumes of acetonitrile mixed with 700 volumes of water containing 0.44% v/v perchloric acid and 0.15% w/v sodium hydroxide previously adjusted to pH 2.0 with 1M sodium hydroxide.SYSTEM SUITABILITYThe test is not valid unless the chromatogram obtained with solution (3) closely resembles the chromatogramsupplied with tamsulosin hydrochloride impurity standard BPCRS.LIMITSIn the chromatogram obtained with solution (1):the area of any peak corresponding to (2R)-N-[2-(2-ethoxyphenoxy)ethyl]-1-(4- methoxyphenyl)propan-2-amine is not greater than 2.5 times the area of the principal peak in the chromatogram obtained with solution (2) (0.5%);the area of any other secondary peak is not greater than the area of the principal peak in the chromatogram obtained with solution (2) (0.2%);the sum of the areas of all secondary peaks is not greater than 7.5 times the area of the principal peak in the chromatogram obtained with solution (2) (1.5%).Disregard any peak with an area less than the area of the principal peak in the chromatogram obtained with solution (4) (0.05%).Uniformity of contentCapsules containing less than 2 mg and/or less than 2% w/w of Tamsulosin Hydrochloride comply with the requirements stated under Capsules using the following method of analysis.Carry out the method for liquid chromatography, Appendix III D, using the following solutions.(1) Mix the contents of 1 capsule with 10 ml of 1M methanolic hydrochloric acid for at least 15 minutes with the aid of ultrasound and with intermittent shaking, filter through a 0.7-µm glass fibre filter, dilute 1 volume of the filtrate to 10 volumes with 1M methanolic hydrochloric acid and filter through a 0.7-µm glass fibre filter.(2) Prepare a 0.040% w/v solution of tamsulosin hydrochloride BPCRS in methanol with the aid of ultrasound, cool and dilute 1 volume to 100 volumes with 1M methanolic hydrochloric acid . CHROMATOGRAPHIC CONDITIONSThe chromatographic conditions described under Related substances may be used.DE TERMINATION OF CONTENTCalculate the content of C20H28N2O5S,HCl in each capsule from the declared content of C20H28N2O5S,HCl in tamsulosin hydrochloride BPCRS.ASSAYCarry out the method for liquid chromatography, Appendix III D, using the following freshly prepared solutions.(1) To a quantity of the powdered mixed contents of 20 capsules containing 1.6 mg of Tamsulosin Hydrochloride add 50 ml of 1M methanolic hydrochloric acid , mix for at least 15 minutes with the aid of ultrasound, cool and add sufficient 1M methanolic hydrochloric acid to produce 100 ml. Filter using a 0.7-µm glass fibre filter and dilute 1 volume of the filtrate to 4 volumes with 0.1M methanolic hydrochloric acid .(2) Prepare a 0.040% w/v solution of tamsulosin hydrochloride BPCRS in methanol with the aid of ultrasound, cool and dilute 1 volume to 100 volumes with 1M methanolic hydrochloric acid . CHROMATOGRAPHIC CONDITIONSThe chromatographic conditions described under Related substances may be used.DE TERMINATION OF CONTENTCalculate the content of C20H28N2O5S,HCl in the capsules from the declared content of C20H28N2O5S,HCl in tamsulosin hydrochloride BPCRS.STORAGEProlonged-release Tamsulosin Capsules should be protected from moisture.IMPURITIESThe impurities limited by the requirements of this monograph include impurit ies B, E, F and H listed under the Tamsulosin Hydrochloride monograph.。

越南卫生部药品注册规定0416

越南卫生部药品注册规定0416

越南药品注册规定(越南卫生部第3121/2001/QD-BYT号决定) 为便于对药品的生产和流通实施统一的国家管理,保障药品的安全、有效和质量可控性,越南卫生部(MOH)决定颁布关于人用防病、治病、补养药品注册的规定(简称为《药品注册规定》).解读:越南的药品注册归口越南卫生部管理。

总则第一条在越南生产和流通的人用防病、治病、补养药品必须进行注册并由卫生部给予注册编号。

在特殊场合下(用于防疫、抗灾的药品及孤儿药),卫生部将依据实际情况允许流通未给予注册编号的药品。

解读:各类药品均须注册,由卫生部颁给注册编号,类似于我国的批准文号。

非常情况下,没有注册编号的药品亦可流通。

第二条调整范围及适用对象2.1 调整范围-——国内外具备生产条件的药品生产企业生产的药品在越南上市前均必须注册。

---科研院所研制的新药,在待技术转让期间,若本单位充分具备生产条件,可申请注册在本单位内生产销售。

解读:与我国不同,具备生产条件的科研院所研制成功的新药在转让前可以生产。

-—-授权生产(under-license)的药品只能在越境内符合药品生产质量管理规范(GMP)的药品生产企业进行生产.解读:貌似我国的委托生产。

-——医疗机构依照诊治病处方配制/生产的服务于本单位诊治疾病的药品,不能在市场上流通。

医疗机构的领导必须对药品的配方、生产规程、质量标准及药品的安全有效性负责。

解读:貌似我国的院内制剂,医院领导负责制。

2.2 适用对象以下各单位可以进行药品注册,在越南进行药品生产和流通:-——越南国内各药品生产企业;--—从事药品贸易的国内企业,获准在药品领域内活动的外国公司。

解读:越南国内的药品生产和经营企业,以及有权限的外国公司均可申请药品注册.这里没有提及科研院所,但从前面条款中不难看出,科研院所、医院等是可以注册药品的。

第三条在本规定内,一些术语做如下理解:3。

1 药品是指用于人防病、治病、减轻病情、诊断疾病或调整机体生理职能的产品。
