Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl methyl cellulose, kurerutsa iyo propyl methyl cellulose (HPMC hydroxypropylmethylcellulose, chidimbu), inofanira kunge iri yeakasiyana-siyana akasanganiswa asiri-ionic cellulose ether.Iyo semi-synthetic, isingashande, viscoelastic polymer inowanzoshandiswa muophthalmology semafuta ekuzora, kana semubatsiri kana excipient mumishonga yemuromo, inowanzo wanikwa mumhando dzakasiyana dzezvigadzirwa.Hydroxypropyl cellulose inogona kushandiswa sechikafu chekuwedzera, emulsifier, thickener, suspension agent uye mhuka inotsiva gelatin.
