Tshuaj pleev ib ce
HPMC yog siv nyob rau hauv cov tshuaj pleev ib ce raws li ib tug thickening neeg sawv cev, muab viscosity thiab kev ntxhib los mos rau cream, gels, thiab lotions.Nws tseem tuaj yeem txhim kho kev ruaj ntseg ntawm kev tsim los ntawm kev txo cov syneresis thiab tiv thaiv kev sib cais theem.

Parenteral Formulation
HPMC yog siv nyob rau hauv parenteral formulations ua ib tug stabilizer thiab thickener.Nws pab tswj lub cev stability ntawm formulation, tiv thaiv particle aggregation thiab sedimentation.Nws kuj yog siv los ua tus neeg sawv cev ncua rau cov tshuaj tsis zoo soluble, kom ntseeg tau tias cov tshuaj sib txawv ntawm cov tshuaj hauv kev tsim.

Tswj Tso Tawm Formulation
HPMC feem ntau yog siv rau hauv kev txhim kho ntawm kev tswj kev tso tawm formulations.Nws tuaj yeem siv los ua cov khoom siv matrix, uas maj mam tso cov tshuaj dhau sijhawm.HPMC kuj tuaj yeem siv los hloov kho cov tshuaj tso tawm los ntawm kev hloov pauv cov ntsiab lus polymer, qhov hnyav molecular, thiab qib hloov pauv.

Mucoadhesive Formulation
HPMC yog siv nyob rau hauv mucoadhesive formulations vim nws muaj peev xwm mus ua raws li mucosal nto.Cov cuab yeej no tuaj yeem siv los txhim kho kev xa tshuaj mus rau qhov ncauj, qhov ntswg, thiab qhov chaw mos mucosa.HPMC kuj tseem tuaj yeem ncua sij hawm nyob hauv kev tsim, txhim kho kev nqus tshuaj thiab bioavailability.

Solubility Txhim Kho
HPMC tuaj yeem siv los txhim kho cov solubility ntawm cov tshuaj tsis zoo soluble.HPMC tsim complexes nrog cov tshuaj, ua rau nws solubility thiab dissolution tus nqi.Lub complexation yog nyob ntawm qhov hnyav molecular thiab degree ntawm kev hloov ntawm HPMC.

Rheology Hloov Kho
HPMC tuaj yeem siv los ua tus hloov kho rheology hauv ntau cov qauv.Nws tuaj yeem nce lossis txo qhov viscosity ntawm cov qauv, nyob ntawm qhov hnyav molecular thiab qib ntawm kev hloov ntawm HPMC.Cov cuab yeej no tuaj yeem siv los kho cov khoom ntws ntawm kev tsim, ua kom yooj yim rau kev tswj thiab txheej txheem.

Kev Kho Hniav Qhov ncauj
HPMC yog siv nyob rau hauv cov tshuaj kho qhov ncauj raws li ib tug thickener thiab binder.Nws tuaj yeem txhim kho qhov kev ntxhib los mos thiab viscosity ntawm cov tshuaj txhuam hniav,nrog rau txhim khu nws stability.Tsis tas li ntawd, HPMC tuaj yeem ua tus neeg sawv cev ua yeeb yaj kiab, muab kev tiv thaiv kev tiv thaiv ntawm cov hniav thiab cov pos hniav.

Suppository Formulation
HPMC yog siv nyob rau hauv suppository formulations raws li ib tug hauv paus khoom.Nws tuaj yeem muab kev tswj xyuas cov tshuaj tso tawm thiab txhim kho kev ua raws li tus neeg mob.HPMC suppositories tsis yog khaus thiab tsis muaj tshuaj lom, ua rau lawv tsim nyog siv rau hauv qhov chaw rhiab heev.

Kev kho mob daim ntawv
HPMC yog siv nyob rau hauv kev kho mob formulations raws li ib tug thickener thiab film-forming tus neeg sawv cev.Nws tuaj yeem pab tsim kev tiv thaiv kab mob ntawm lub qhov txhab, tiv thaiv kab mob thiab txhawb kev kho mob.HPMC tseem tuaj yeem txhim kho cov viscosity thiab kev ntxhib los mos ntawm cov ntaub qhwv lub qhov txhab, ua rau lawv yooj yim rau kev thov thiab tshem tawm.
