Abstract

INTRODUCTION: Polymeric micelles represent nowadays an interesting formulative approach for ocular drug delivery, as they act as solubility enhancers of poorly soluble drugs and promote drug transport across cornea and sclera. In particular, in the last 5 years polymeric nanomicelles have been increasingly investigated to overcome some of the important challenges of the topical treatment of ocular diseases. AREAS COVERED: The aim of this review was to gather up-to-date information on the different roles that polymeric micelles (commonly in the nanosize scale) can play in ocular delivery. Thus, after a general description of ocular barriers and micelles features, the attention is focused on those properties that are relevant for ophthalmic application. Finally, their efficacy in improving the ocular delivery of different classes of therapeutics (anti-inflammatory, immunosuppressant, antiglaucoma, antifungal, and antiviral drugs) are reported. EXPERT OPINION: Although still a few, in vivo experiments have clearly demonstrated the capability of polymeric nanomicelles to overcome a variety of hurdles associated to ocular therapy, notably increasing drug bioavailability. However, there are still some very important issues to be solved, such as tolerability and stability; additionally, the role of micelles in drug uptake by the ocular tissues and their potential for the treatment of posterior eye diseases still need to be clarified/verified.

  • Growing evidence indicates that nanomicelles can be utilized for addressing ocular surface inflammation, retinal degeneration and vascular proliferative disorders.

    “Growing evidence indicates that nanomicelles can be utilized for addressing ocular surface inflammation, retinal degeneration and vascular proliferative disorders [93].”
  • The most investigated administration route for micelles is intravenous injection/infusion, mainly for chemotherapy, but improved drug bioavailability has also been reported following oral and topical administration.

    “The most investigated administration route for micelles is the intravenous (i.v.) injection/infusion (mainly exploited for chemotherapy) [18,[47][48][49], but very interesting results in terms of improved drug bioavailability have also been reported following oral [31,50] and topical (ocular, nasal, buccal) [26,36,51,52] administration.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
