1. Aspectus: Specimen pone in charta alba et observa speciem, extemporalitatem in pallide lutei pulveris.
2. Analysis:
2.1 Punctum liquatum determinatio secundum legem (Pharmacopoea Sinica 2010 Editionis II Appendix C) punctum liquefactum est 142.0~ 148.0℃.
2.2 Detrimentum in siccitate: Determinatio secundum legem (Appendix L, Pars II, 2010 Pharmacopoeia Sinensium Editio).Subtilitas pensans debitum huius facti quantitatem, sicca ad 102℃ per 3 horas, pondus damnum non plus quam 1.00% erit.
2.3 Metalla gravia: Determinatio secundum legem (Pharmacopoea Popularis Sinarum 2010 Editio, Pars II Appendix H) Determinatio secunda methodus.
Subtilitas ponderis 1.0g probati producti, lente urentis usque ad perfecte carbonisatum, refrigerandum, adde acidum sulphuricum 0.5-1.0ml, humidum fac, calorem ad frigiditatem temperatam donec acidum sulphuricum defatigat, adde acidum nitricum 0.5ml, vaporem siccum, donec vapor oxydi nitrogeni exhausto, frigidus, calidus in 500-600℃ ut omnino carbonisatus, frigidus, acidum 2ml hydrochloricum addas, Postquam in aqua balnei siccatus, aquam 15ml adde, ammoniacam solutionem experimenti demitte donec neutrum fiat ad indicator phenolphthalein. solutio, acetas quiddam (ph3.5), 2ml acetatum quiddam (ph3.5), leviter calor dissolve, ad Nachner tubum colorimetricam move, et in 25ml cum aqua dilue.Accipe aliam gerentem ad solutionem experimenti praeparandam et in catino porcellano vapore, adde quiddam 2ml acetatis (PH3.5) et aquae 15ml ad leviter calefaciendum Post dissolutionem, move tubus Nath colorimetric, adde solutionem quamdam vexillum plumbi; deinde aqua dilutum 25ml.Experimentum colorimericum exercetur inter solutionem testium et solutionem regulae obtinendam.Praeparatio solutionis Standardi secundum (Pharmacopoea Popularis Sinarum 2010 edition II Appendix Methodus metalli gravis examinis) methodus prima.Metalla gravia non debent viginti partes per miliones excedere.
3. Puritas: Iuxta summum perficiendi liquidum chromatographiam, secundum legem determinatum (Pharmacopoea Sinica 2010 II Appendix VD editio).

224789-21-3 -Applicatio:

2-(2-Ethoxyphenyl)-5-Methyl-7-Propylimidazo[5,1-F][1,2,4]triazin-4(3H)-unum (CAS: 224789-21-3) medium est Vardenafil (CAS: 224785-90-4) / Vardenafil Hydrochloridis (CAS: 224785-91-5).Vardenafil novus PDE5 inhibitor ad tractationem oralis dysfunctionem masculinorum deductam est et structuram significantem similitudinem cum sildenafil (Viagra), quae primus PDE5 inhibitor anno 1998 ad hanc indicationem introductus est.
Vardenafilus erat secundus agens venales et commodum habuit quod eius temporis impetus non minuebatur medicamentum in ventre pleno sumendo.XXX vicibus potentior est ut inhibitor PDE5 (medii IC50, 3.9 nM) quam sildenafili et 10 temporibus potentius quam tadalafili, cum maiore electione hominum PDE5 quam pro humano PDE2, PDE3 et PDE4 et moderata selectivity (>80 times) pro PDE1.Electio inhibitoriae PDE et tam in vitro quam in potentia vivo inhibitoris vardenafili novi PDE5.Vardenafil hydrolysim cGMP per PDE5 specialiter inhibuit, cum IC50 0,7 nM (sildenafil 6.6 nM).IC50 vardenafili pro PDE1 erat 180 nM, pro PDE6 11 nM, & PDE2, PDE3 & PDE4 plusquam 1000 nM.
