Diseases and conditions associated with tissues of the body, including but not limited to tissues in the eye, can be effectively treated, prevented, inhibited, onset delayed, or regression caused by administering therapeutic agents to those tissues. Described herein are ophthalmic formulations that deliver a variety of therapeutic agents, including but not limited to rapamycin (sirolimus), analogs thereof (rapalogs) or other mTOR inhibitors, to a subject for an extended period of time. The ophthalmic formulations may be placed in an aqueous medium of a subject, including but not limited to intraocular or periocular administration, or placement proximate to a site of a disease or condition to be treated in a subject. A method may be used to administer a therapeutic agent to treat or prevent age-related macular degeneration, macular edema, diabetic retinopathy, uveitis, dry eye, or a hyperpermeability disease in a subject.


In the course of developing 2-[[[2-[(hydroxyacetyl) amino]-4-pyridinyl] methyl] thio]-N-[4-(trifluoromethoxy) phenyl]-3-pyridinecarboxamide (compound A), there are the multiple problems: 1) compound A or its salt is difficult to be recrystallized, the storage stability largely differs depending on the kind of the salt, and it is very difficult to obtain a salt of compound A having excellent storage stability; 2) in a crystallization process of compound A, it is very difficult to control a crystal polymorph, and 3) compound A (free body) causes mineral deposition in the stomach when it is orally administered repeatedly. For solving these problems, we made examination focusing on the kind of the salt and, as a result, found that 1) benzenesulfonate of compound A does not decompose by light, humidity and other factors in a 1-week preliminary stability test (severe test), and has no problem in its storage stability, 2) a method of selectively producing two kinds of crystal forms of benzenesulfonate of compound A, and that 3) no mineral deposition in the stomach is observed even after a 4-week repeated oral administration.

Described herein are liquid formulations which deliver a variety of therapeutic agents, including but not limited to rapamycin, to a subject for an extended period of time; liquid formulations which form a non-dispersed mass when placed in an aqueous medium of a subject; liquid formulations comprising a therapeutic agent and a plurality of polymers; and methods for delivering therapeutic agents to a subject for an extended period of time using the liquid formulations. The liquid formulation may be placed in an aqueous medium of a subject, including but not limited to via intraocular or periocular administration. A method may be used to administer rapamycin to treat or prevent angiogenesis, choroidal neovascularization, or age-related macular degeneration in a subject.

Regarding Diquafosol ophthalmic solution comprising a chelating agent at a concentration of 0.0001 to 1% (w/v), formation of insoluble precipitates found in Diquafosol ophthalmic solution during storage of the solution, as well as deterioration of the filtration performance in the course of production (course of filtration sterilization), have been inhibited. Further, in Diquafosol ophthalmic solution comprising a chelating agent, reduction of eye irritation and enhancement of the preservative effectiveness have been confirmed, in comparison to Diquafosol ophthalmic solution comprising no chelating agent. Accordingly, the present invention has been confirmed to provide physicochemical properties that are stable during the courses of production and distribution as well as the course of storage by a patient, and also reduce eye irritation and enhance preservative effectiveness.
