  • Patent number: 11969410
    Abstract: The present invention provides relatively low pH, stable, pharmaceutically acceptable and ophthalmologically suitable compositions comprising effective amounts of pilocarpine and brimonidine compounds for treating an ocular condition, wherein compositions demonstrate a significant difference in the amount or rate of one or more pharmaceutical ingredient(s) absorbed or retained by ocular tissue or compared to reference composition(s) with similar compositional characteristics but having a significantly higher pH. In aspects compositions are characterizable by other elements, e.g., the inclusion of benzalkonium chloride, a limited amount of sodium chloride, or both. In embodiments, compositions are free of both a borate and a citrate buffer. Compositions provided by the invention surprisingly demonstrate pharmaceutically acceptable stability when stored under controlled room temperature conditions for an extended period of time.

  • Patent number: 11857538
    Abstract: Disclosed herein, are, among other things, stable, pharmaceutically acceptable and ophthalmologically suitable reduced buffer content and reduced buffering capacity pilocarpine compound compositions. In aspects, such compositions comprise therapeutically effective amounts of a pilocarpine compound, an effective amount of a uniform buffer component, wherein the concentrations of pilocarpine compound and uniform buffer component are limited to specific relative amounts and wherein the uniform buffer component is defined by one or more markedly distinguishing characteristics from buffers used in developed pilocarpine products (e.g., a unique pKa and/or concentration). Aspects of the invention include compositions defined by unique concentrations of such and other ingredients. Such compositions surprisingly exhibit pharmaceutically acceptable stability and, in aspects, stability equal to or statistically significantly greater than that of one or more on-market/developed reference product(s).
