Mhando dzezvakarebeswa-kuburitswa mafomu

Kurongwa nenzira yekutonga

1. Mapiritsi (akaputirwa mahwendefa, matrix mahwendefa, akawanda-layer mapiritsi), mapiritsi, capsules (enteric-coated capsules, mishonga resin capsules, yakavharwa capsules) nezvimwewo zvinotungamirirwa kuburikidza nemakumbo emimba.

2. Parenteral administration yemajekiseni, suppositories, mafirimu, implants, nezvimwewo.

Zvinoenderana neakasiyana maitiro ekugadzirira, kugadzirira-kuburitswa kwakasimba kunogona kukamurwa kuita:

1. Skeleton-yakapararira-yakagadziriswa-yakagadziriswa gadziriro ①Water-soluble matrix, carboxymethylcellulose (CMC), hydroxypropylmethylcellulose (HPMC), polyvinylpyrrolidone (PVP), nezvimwewo zvinowanzoshandiswa sematrix zvinhu; ②Fat-soluble matrix, Mafuta uye wakisi zvinhu zvinowanzo shandiswa sema skeleton zvinhu; ③ isina kunyungudika skeleton, isinganyungudika isina-chepfu mapurasitiki anowanzo shandiswa se skeleton zvinhu.

2. Membrane-inodzorwa-inosimudzira-kusunungurwa gadziriro inowanzobatanidza firimu-yakavharidzirwa inosimudzira-yakagadziriswa gadziriro uye inochengetedza-kuburitsa microcapsules. Chinangwa chekudzora chiyero chekuburitswa kwezvinodhaka chinowanzo kuwanikwa nekudzora ukobvu hwekapisi, dhayamita yemicropores, uye curvature yemakropores.

3. Emulsions yakagadziriswa Mishonga inonyungudika nemvura inogona kugadzirwa muW / O emulsions, nokuti mafuta ane chimwe chipingamupinyi chinokonzera pakupararira kwemishonga inodhaka kuti iwane chinangwa chekusunungurwa kwakasimba.

4. Kugadziriswa-kusunungurwa kwekugadzirira kwejekiseni kunogadzirwa nemafuta ekugadzirisa uye majekiseni ekumisa.

5. Kugadziriswa-kusunungurwa kwemafirimu gadziriro inogara-kusunungurwa kwefirimu gadziriro dzakaitwa ne encapsulating mishonga muzvikamu zvemafirimu epolymer, kana kunyungudutswa nekuaparadzira mumapepa emafirimu epolymer.
