Definitions

  • Warts can result from viral infections that are most often associated with Human Papilloma Virus (HPV) or Molluscum Contagiosum Virus (MCV). Non-genital varieties of skin warts occur in 20% of schoolchildren with equal frequency in both sexes.
  • Viral or viral wart infection, demodex infection, fungal or yeast infection, or bacterial infection of the eyelids, conjunctiva, cornea, ocular surface or Meibomian glands can manifest as blepharitis and/or blepharoconjunctivitis or conjunctivitis– an infectious and inflammatory condition of the eyelid or ocular surface.
  • Blepharoconjunctivitis and blepharitis are commonly encountered conditions affecting approximately 15% of the population, and represent an inflammatory, infectious or mixed condition of the eyelids.
  • Blepharitis may involve the dermis, eyelashes, tarsal conjunctiva, mucocutaneous junction or Meibomian glands and is most often caused by gram positive bacterial infection, such as Staphylococcus, Corynebacterium, and Propionibacterium species.
  • other agents causing blepharitis include viral, demodex (mite), or yeast infections, seborrhea, rosacea, and hormonal dysregulation.
  • blepharitis Left untreated, blepharitis may cause dry eye exacerbation, loss of cilia, corneal ulceration, and impart increased risk of endophthalmitis after cataract surgery. For facility in understanding, it is commonly compartmentalized into inflammation affecting the structures of the anterior, posterior lid margin or both.
  • Anterior blepharitis most commonly presents as anterior lid and lash crusting with or without the presence of collarettes. Other manifestations may also include skin or lash flaking associated with seborrhea or angular inflammation particular to Moraxella or virus.
  • Posterior blepharitis is also commonly referred to as Meibomian gland disease.
  • Meibomian glands are responsible for the release of lipids into the tear film, effectively mitigating evaporative tear loss.
  • the posterior variant may further be characterized by inspissation of the Meibomian glands, keratinization of orifices, telangiectasia, and posterior margin lid thickening.
  • Bacterial lipases stemming from the ocular flora may also act upon Meibomian secretions creating free fatty acids which further disturb the ocular surface.
  • compositions comprising an iodophor such as povidone-iodine (PVP-I), as an active ingredient, and dimethyl sulfoxide (DMSO) were shown to be useful for treating fungal infections of the skin and nails. See, e.g., US Publication No.
  • PVP-I povidone-iodine
  • DMSO dimethyl sulfoxide
  • PVP-I preparations range in molecular weights from 1,000 to 1,000,000 or more.
  • Topical pharmaceutical compositions have been approved using only PVP grades K29-32.
  • PVP K30 One acceptable PVP grade is PVP K30, which has a MW of 30,000 to 60,000 Daltons (average MW of about 40,000 Daltons). Accordingly, prior to the teachings of Capriotti‘559, one skilled in the art would not employ DMSO in a topical pharmaceutical composition to enhance skin penetration of large molecules, polymers or high-molecular weight substances such as PVP-I.
  • Ophthalmic preparations were not previously known to contain above 2.0% gelling agent, such as a cellulosic gel, e.g., hydroxyethylcellulose (HEC).
  • HEC hydroxyethylcellulose
  • DMSO was understood and accepted in the art to be potentially toxic to the eye and was not considered to be an ophthalmically acceptable ingredient in a composition intended for topical administration to the eye or periocular region. Therefore, not only was DMSO generally recognized as being unacceptable for use as a penetration enhancer for high molecular weight polymeric compounds, such as povidone-iodine, DMSO was particularly avoided as an ingredient for use in ophthalmic preparations, and especially avoided as an ingredient for topical ophthalmic preparations. [00013] In US Patent Application, US Pub. No. 2017/0000819, Capriotti, et al., described topical ophthalmic gel compositions for treatment of certain ophthalmic conditions.
  • compositions were not stable for a sufficient period of time to provide a viable pharmaceutical product having an acceptable shelf-life, when concentrations of gelling agent, e.g., HEC, were less than 2%. Therefore, it was previously unknown that topical ophthalmic gel formulations comprising less than 2% povidone-iodine (PVP-I) and DMSO, with a gelling agent, could be made having pharmaceutically acceptable properties and utility. Only when particular amounts of povidone-iodine were combined with particular amounts of DMSO and particular amounts of gelling agent, and pH-adjusted, was stability observed to be sufficient to provide a viable pharmaceutically acceptable product having an acceptable and approvable shelf-life.
  • PVP-I povidone-iodine
  • the subject formulation is therefore unexpectedly effective and stable, making it useful in treating certain viral, demodex, fungal/yeast, or bacterial infections manifesting as ophthalmic conditions (e.g., blepharitis, blepharoconjunctivitis, viral conjunctivitis, bacterial conjunctivitis, keratitis, or the like.)
  • ophthalmic conditions e.g., blepharitis, blepharoconjunctivitis, viral conjunctivitis, bacterial conjunctivitis, keratitis, or the like.
  • compositions comprising concentrations of DMSO at 10% and greater, and gelling agent less than 5%, including concentrations between 1% and 5%, can be advantageous for proper administration or application of the product, residence time at the site of treatment, or aesthetic reasons (look/feel and patient acceptance of the product).
  • discovery of a composition comprising PVP-I in DMSO, and water with or without an organic co-solvent, and a gelling agent concentration less than 5%, which is stable and effective for acceptable periods of time can represent a significant advancement to the medical arts, especially to the art of ophthalmic treatment.
  • the current invention is a significant advance in the art, and discloses the surprising and unexpected discovery that a topical ophthalmic gel composition comprising particular ingredients, namely, PVP-I, DMSO, and a gelling agent, in particular concentration combinations, can provide advantageous and unexpected results in the preparation and stabilization of ophthalmic formulations for the treatment of infection of the eye such as blepharitis, conjunctivitis, keratitis or other eye conditions.
