The present invention relates to compositions and methods of using those compositions for the diagnosis and treatment of immune related diseases.

Compositions comprised of a delivery vehicle or delivery system and an active agent dispersed within the delivery vehicle or system, wherein the delivery vehicle or system contains a polyorthoester polymer and a polar aprotic solvent. Also disclosed are low viscosity delivery systems for administration of active agents. The low viscosity delivery systems have a polyorthoester polymer, a polar aprotic solvent and a solvent containing a triglyceride viscosity reducing agent. Compositions described include an amide- or anilide-type local anesthetic of the “caine” classification, and a non-steroidal anti-inflammatory drug (NSAID), along with related methods, e.g., for treatment of post-operative pain or for prophylactic treatment of pain. The compositions are suitable for delivery via, e.g., direct application and instillation, intradermal injection, subcutaneous injection, and nerve block (perineural).

The Invention provides compounds of Formula (I) and pharmaceutically acceptable salts, solvates, hydrates, N-oxides, or diastereomers thereof: wherein W.sup.1, W.sup.2, W.sup.3, J.sup.1, J.sup.2, A, R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, a, and b are defined as set forth in the specification. The Invention also provides uses of the compounds of any one of Formulae (I)-(VIII) and the pharmaceutically acceptable salts, solvates, hydrates, N-oxides, or diastereomers thereof. Compounds of the Invention are useful for treating a disorder responsive to blockade of one or more sodium channels. In certain embodiments, Compounds of the Invention are useful for treating pain. ##STR00001##

Provided herein are topical ophthalmic preparations which comprise a non-aqueous, self-emulsifying system which can spontaneously give rise to either nanosized emulsions upon contact with an aqueous phase. Also provided herein are methods for the preparation of the same and their use in formulating and delivering poorly water soluble drugs.

The present invention provides a micelle comprising an anionic micelle and a protecting agent surrounding the anionic micelle, the anionic micelle being formed from, as a structural unit, an ingredient that has a functional group capable of being anionized under basic conditions and has anionic micelle-forming ability, the protecting agent protecting the anionic micelle. The present invention also provides a micelle comprising a cationic micelle and a protecting agent surrounding the cationic micelle, the cationic micelle being formed from, as a structural unit, an ingredient that has a functional group capable of being cationized under acidic conditions and has cationic micelle-forming ability, the protecting agent protecting the cationic micelle.

A pain relieving aerosol spray (pain relieving and pain preventing aerosol spray) comprising a pain relieving composition and at least one refrigerant, wherein the pain relieving aerosol spray is capable of providing rapid onset local anaesthesia of intact skin and/or a wound of a subject to which it is applied and further pain relief due to the pain relieving composition remaining on the wound of the subject. The pain relieving composition comprises a liquid gel matrix that contains at least one anaesthetic agent, a vasoconstrictor, and an antiseptic agent. The spray can be used for a surgical procedure or animal husbandry procedure, such as castration or branding, or treating a burn or wound.

The present disclosure relates to sustained release drug delivery systems. In some cases, a composition comprises an active pharmaceutical agent; at least one of sucrose acetate isobutyrate and a polyorthoester; an organic solvent; and 2,6-dimethylaniline, wherein the 2,6-dimethylaniline is present at a level less than 500 ppm. In some cases, a composition comprises N-oxide of active pharmaceutical agent at a level less than 1 wt %, based on weight of the composition. In some case, a composition comprises metal present at a level less than 5 ppm. Dosage forms and methods are also provided.
