OCUFEN  (flurbiprofen sodium ophthalmic solution, USP) 0.03% Sterile DESCRIPTION OCUFEN  (flurbiprofen sodium ophthalmic solution, USP) 0.03% is a sterile topical nonsteroidal anti-inflammatory product for ophthalmic use.Contains: Active: flurbiprofen sodium 0.03% (0.3 mg/mL). Preservative: thimerosal 0.005%. Inactives: citric acid; edetate disodium; polyvinyl alcohol 1.4%; potassium chloride; purified water; sodium chloride; and sodium citrate. May also contain hydrochloric acid and/or sodium hydroxide to adjust the pH. The pH of OCUFEN  ophthalmic solution is 6.0 to 7.0. It has an osmolality of 260-330 mOsm/kg. CLINICAL PHARMACOLOGYFlurbiprofen sodium is one of a series of phenylalkanoic acids that have shown analgesic, antipyretic, and anti-inflammatory activity in animal inflammatory diseases. Its mechanism of action is believed to be through inhibition of the cyclo-oxygenase enzyme that is essential in the biosynthesis of prostaglandins.Prostaglandins have been shown in many animal models to be mediators of certain kinds of intraocular inflammation. In studies performed on animal eyes, prostaglandins have been shown to produce disruption of the blood-aqueous humor barrier, vasodilatation, increased vascular permeability, leukocytosis, and increased intraocular pressure.

Earth‐abundant amorphous nanomaterials with rich structural defects are promising alternative catalysts to noble metals for an efficient electrochemical oxygen evolution reaction; however, their inferior electrical conductivity and poor morphological control during synthesis hamper the full realization of their potency in electrocatalysis. Herein, a rapid surface‐guided synthetic approach is proposed to introduce amorphous and mixed‐metal oxyhydroxide overlayers on ultrathin Ni‐doped MnO2 (NiMnO2) nanosheet arrays via a galvanic replacement mechanism. This method results in a monolithic 3D porous catalyst with a small overpotential of only 232 mV to achieve a current density of 10 mA cm−2 in 1 m KOH, which is much lower than the corresponding value of 307 mV for the NiMnO2 reference sample. Detailed structural and electrochemical characterization reveal that the unique NiMnO2 ultrathin nanosheet arrays do not only provide a large surface area to guide the formation of active amorphous catalyst layers but also ensure the effective charge transport owing to their high electron conductivity, collectively contributing to the greatly improved catalyst activity. It is envisioned that this highly operable surface‐guide synthetic strategy may open up new avenues for the design and fabrication of novel 3D nanoarchitectures integrated with functional amorphous materials for broadened ranges of applications.
