Aplicación

Poly(D,L-lactide-co-glycolide) (PLGA) canbe used:

  • In the formulation ofa non-aqueous drug delivery system for H2S donors to aid thesustained release of the drug.
  • To prepare a polymer blend containing Ganciclovir-loaded microspheresdispersed in PLGA–PEG–PLGA polymer gel. This formulation can be used as asustained delivery system for Ganciclovir drug.
It can also be used to fabricate NO-releasingglucose and lactate sensors.

Hydrogen sulfide (H2S) targets both underlying factors in glaucoma pathogenesis by reducing elevated intraocular pressure (IOP) and providing retinal neuroprotection, whereas the current clinical approaches targets only reducing IOP. Therefore, H2S could be a potential superior candidate for glaucoma pharmacotherapy.
