摘要:
Provided is concentrated aqueous azithromycin formulation from about from about 2%-20%, and a method of making a concentrated aqueous azithromycin formulation which includes preparing and sterilizing a first solution comprising a strong base to form a sterilized solution, dissolving the azithromycin in an aqueous solution comprising an acid consisting essentially of a strong acid, and adding the aqueous solution comprising the strong acid to the sterilized solution comprising the strong base. The strong acid has a pKa less than about −1.74 and the method is carried out without addition or use of a weak acid.
摘要:
Methods and compositions for preventing or treating ophthalmic diseases or disorders wherein an ophthalmically effective amount of the C20 through C26 aminosteroids of formula (XI) and their pharmaceutical, acceptable salts, hydrates or solvates is administered in an inert vehicle to arrest oxidation processes damaging to the eye.
摘要:
Polymères légèrement réticulés, que l'on prépare de préférence en polymérisant en suspension ou en émulsion au moins environ 90 % en poids d'un monomère monoéthylémiquement insaturé contenant du carboxyle tel que l'acide acrylique avec d'environ 0,1 % à environ 5 % en poids d'un agent de réticulation à plusieurs fonctions, et de préférence à deux fonctions, tel que le divinyl-glycol dont la taille des particules ne dépasse pas environ 5 um de diamètre sphérique équivalent lorsqu'ils sont formulés avec un médicament ophtalmique, en suspension dans un milieu aqueux dans lequel la quantité de polymères va d'environ 0,1 % à environ 6,5 % en poids, basée sur le poids total de la suspension aqueuse, le pH est situé entre environ 3,0 et environ 6,5 et la pression osmotique (osmolalité ou pression osmotique efficace) se situe entre environ 10 mOsM et environ 400 mOsM. Ces polymères constituent de nouveaux systèmes d'application topique de médicament ophtalmiques ayant une viscosité convenablement basse qui leur permet d'être facilement appliqués dans l'oeil sous forme de gouttes.
摘要:
A disposable unit or multi-dose dispenser for dispensing ophthalmic liquid medicant in the form of droplets to the eye. The structural configuration of the device includes an angularly offset leading end (32) to permit the user to employ a free hand for manipulation of the eyelid to enhance reception of the discharge opening of the dispenser into the conjunctival cul-de-sac while at the same time enabling the user to look directly into a wall-mounted mirror to aid in accurate placement of medicant. A small capacity reservoir (20) is sealed by a frangible closure (40) until it is desired to dispense the medicant.
摘要:
Lipophilic, transient ester derivatives of timolol represented by general formula (I), wherein R1 represents a substituted or unsubstituted branched chain alkyl, straight or branched chain alkenyl, aryl, aralkyl or cycloalkyl group, a substituted or unsubstituted aromatic 5- or 6-membered heterocyclic ring containing one or two heteroatoms selected from the group consisting of nitrogen, oxygen and sulfur, or a substituted or unsubstituted group of the formula R2-O-, wherein R2 is an alkyl, aryl, aralkyl or cycloalkyl group or of the formula R'2-CONH, wherein R'2 is an alkyl, aryl, aralkyl or cycloalkyl group, and nontoxic pharmaceutically acceptable acid addition salts thereof, are disclosed as prodrug forms of the anti-glaucoma drug timolol which are also useful in the treatment of glaucoma and increased intraocular pressure and which exhibit either improved corneal absorption and/or impeded conjunctival absorption characteristics, thus permitting the use of smaller doses of such derivatives than of timolol, thereby reducing systemic timolol concentration while achieving the same therapeutic effect.
