Ibintu nyamukuru bigize ibirahuri ni quartz (silika). Quartz ifite imbaraga zo kurwanya amazi (nukuvuga, ntibishobora gufata amazi). Ariko, kubera aho hejuru yo gushonga (hafi 2000 ° C) nigiciro kinini cya silika-isukuye cyane, ntibikwiriye gukoreshwa Misa; Ongeraho imiyoboro ihindura imiyoboro irashobora kugabanya gushonga kwikirahure no kugabanya igiciro. Guhindura imiyoboro rusange ni sodium, calcium, nibindi.; ariko abahindura imiyoboro bazahana hydrogene ion mumazi, bigabanye kurwanya amazi yikirahure; wongeyeho boron na Aluminium birashobora gushimangira imiterere yikirahure, ubushyuhe bwo gushonga bwarazamutse, ariko kurwanya amazi byateye imbere cyane.
Ibikoresho byo gupakira imiti birashobora kuvugana nibiyobyabwenge, kandi ubuziranenge bwabyo bizagira ingaruka kumutekano no guhagarara kwimiti. Ku kirahure cy’imiti, kimwe mu bipimo ngenderwaho mu bwiza bwacyo ni ukurwanya amazi: uko amazi arwanya amazi, niko ibyago byo kwandura ibiyobyabwenge, ndetse n’ubuziranenge bw’ikirahure.
Ukurikije kurwanya amazi kuva hasi kugeza hejuru, ikirahuri cyimiti gishobora kugabanywamo: ikirahuri cya soda, ikirahuri cya borosilike nkeya hamwe nikirahure cya borosilike. Muri Pharmacopoeia, ikirahuri cyashyizwe mubyiciro I, Icyiciro cya II, nicyiciro cya III. Icyiciro cya I kirahure cyiza cya borosilike kibereye gupakira imiti yatewe, naho ikirahuri cya soda yo mucyiciro cya III gikoreshwa mugupakira amazi yo mu kanwa hamwe nibiyobyabwenge bikomeye, kandi ntibikwiye kumiti yatewe.
Kera, ikirahuri cya borosilike nkeya hamwe nikirahure cya soda-lime byakoreshwaga mubirahuri bya farumasi yo murugo. Nk’uko bigaragazwa na “Raporo yimbitse y’ubushakashatsi n’ishoramari kuri Pharmaceutical Glass Package yo mu Bushinwa (Edition Edition)”, ikoreshwa rya borosilike mu kirahure cy’imiti mu gihugu cya 2018 ryagize 7-8% gusa. Icyakora, kuva Amerika, Uburayi, Ubuyapani, n'Uburusiya byose bitegeka gukoresha ikirahuri cya borosilike kidafite aho kibogamiye mu gutegura inshinge zose no gutegura ibinyabuzima, ikirahuri giciriritse cyakoreshejwe cyane mu nganda z’imiti yo mu mahanga.
Usibye gutondekanya ukurikije kurwanya amazi, ukurikije uburyo butandukanye bwo gukora, ikirahuri cyimiti kigabanyijemo amacupa yabumbwe hamwe nuducupa tugenzurwa. Icupa ryabumbwe ni ugutera mu buryo butaziguye amazi yikirahure muburyo bwo gukora icupa ryimiti; mugihe icupa ryo kugenzura rigomba kubanza gukora ibirahuri byamazi mubirahure, hanyuma ukata ikirahuri kugirango ukore icupa ryimiti
Raporo y’isesengura y’inganda zikoreshwa mu gupakira ibirahuri mu mwaka wa 2019, amacupa yatewe inshinge zingana na 55% by’ibirahure bya farumasi kandi ni kimwe mu bicuruzwa by’ibirahure bya farumasi. Mu myaka yashize, igurishwa ry’inshinge mu Bushinwa ryakomeje kwiyongera, bituma icyifuzo cy’amacupa y’inshinge gikomeza kwiyongera, kandi impinduka muri politiki zijyanye no gutera inshinge zizatera impinduka ku isoko ry’ibirahuri bya farumasi.
