Gusaba

Polyvinylpyrrolidone ikoreshwa cyane mubijyanye n'ubuvuzi kandi ni kimwe mu bintu bitatu bishya bivura imiti byunganirwa ku rwego mpuzamahanga. Ibikoresho bifata cyane ni ibinini na granules. Irashobora kandi gukoreshwa nkimfashanyo itemba ya capsules, kwangiza no gusiga amavuta kumiti yijisho, gufatira hamwe gutera inshinge, gutatanya imyiteguro yamazi, hamwe na stabilisateur ya enzymes nibiyobyabwenge byangiza ubushyuhe. Povidone irashobora kandi guhuzwa na iyode povidone iyode (PVP-I) yangiza. Muburyo bwo guhuza amakuru, PVP ikoreshwa nkigice cyo guhuza amakuru kugirango yongere hydrophilicity. PVP irashobora kandi gukoreshwa nkuburinzi bwa kirogenike mubuvuzi.
