| POVIDONE-K90 | (C6H9NO) n |
Povidone (polyvinylpyrrolidone, PVP) ikoreshwa mu nganda zimiti nkimodoka ya sintetike ya polymer yo gukwirakwiza no guhagarika ibiyobyabwenge.Ifite imikoreshereze myinshi, harimo nka binder ya tableti na capsules, firime yahoze ikemura ibibazo byamaso, kugirango ifashe uburyohe bwamazi hamwe nibinini byoroshye, kandi nkibikoresho bya sisitemu ya transdermal.
Povidone ifite molekuline ya (C6H9NO) n kandi igaragara nkifu yera kugeza gato-ifu yera.Imiti ya Povidone ikoreshwa cyane mu nganda zimiti kubera ubushobozi bwayo bwo gushonga haba mumazi no mumavuta.Umubare wa k bivuga uburemere buke bwa povidone.Povidone ifite K-indangagaciro (urugero, k90) ntabwo itangwa mugutera inshinge kubera uburemere buke bwa molekile.Ibiro byinshi bya molekuline birinda gusohora impyiko biganisha ku kwirundanya mu mubiri.Urugero ruzwi cyane rwa povidone ni povidone-iyode, yangiza cyane.
Gutemba kubuntu, ifu yera, gutuza neza, kutarakara, gushonga mumazi na ethnol, umutekanokandi byoroshye gukoresha, .Ingirakamaro mukwica bacillus, virusi & epiphytes.Bihuye nubuso bwinshi.
Bibaho nkubuntu butemba, ifu yumutuku wijimye, idatera uburakari hamwe no guhagarara neza, gushonga mumazi n'inzoga, bidashonga muri diethylethe na chloroform.

Polyvinylpyrrolidone mubisanzwe muburyo bwa powder cyangwa igisubizo kibaho.PVP mu kwisiga mousse, guturika, no kumisatsi, irangi, icapiro wino, imyenda, gucapa no gusiga irangi, amabara yerekana amabara arashobora gukoreshwa nkibikoresho byo gutwikira hejuru, gukwirakwiza ibintu, kubyimba, guhambira.Mubuvuzi hakoreshwa cyane binders kubinini, granules nibindi.
