Amino-Functionalized Mesoporous Silica Particles for Ocular Delivery of Brimonidine.

To treat glaucoma, conventional eye drops are often prescribed. However, the eye drops have limited effectiveness as a result of low drug bioavailability due to their rapid clearance from the preocular space. To resolve this, we proposed amino-functionalized mesoporous silica (AMS) particles as delivery carriers of the glaucoma drug, brimonidine. Because of the presence of mesopores, brimonidine (BMD) could be encapsulated in the AMS with a loading amount of 41.73 μg/mg (i.e., drug loading capacity of abou...

Metal-organic Frameworks, NH-MIL-88(Fe), as Carriers for Ophthalmic Delivery of Brimonidine.

We have proposed a metal-organic framework (MOF), NH-MIL-88(Fe), as a novel carrier for topical drug delivery to the eye. The NH-MIL-88(Fe) particles were prepared via a solvothermal synthesis method and their structure was confirmed by powder X-ray diffraction, Fourier transform infrared analysis, thermogravimetric analysis, electron microscopy, and N adsorption-desorption measurements. When brimonidine, an anti-glaucoma medicine, was encapsulated into NH-MIL(Fe)-88 (i.e., NH-MIL-88(Fe)/Br), the drug was l...

Reduction of Ultraviolet B Light-Induced Erythema by Oxymetazoline and Brimonidine Is Mediated by Different α-Adrenoceptors.

When applied topically, oxymetazoline and brimonidine reduce the persistent facial erythema of rosacea; this effect is mediated by cutaneous vasoconstriction induced by postsynaptic activation of α-adrenoceptors. We investigated the α-adrenergic pharmacology of oxymetazoline and brimonidine. Functional activity on α-adrenoceptors was evaluated in vitro in HEK293 cells stably expressing single receptor subtypes using a fluorometric imaging plate reader Ca influx assay. Oxymetazoline was an α -adrenocepto...

Brimonidine displays anti-inflammatory properties in the skin through the modulation of the vascular barrier function.

Rosacea is a chronic inflammatory skin disease. Characteristic vascular changes in rosacea skin include enlarged, dilated vessels of the upper dermis and blood flow increase. Brimonidine is approved for symptomatic relief of the erythema of rosacea. It acts by selectively binding to α2-adrenergic receptors present on smooth muscle in the peripheral vasculature, resulting in transient local vasoconstriction.

Topical brimonidine-assisted laser treatment for the prevention of therapy-related erythema and hyperpigmentation.

Postinflammatory hyperpigmentation (PIH) and erythema are the most common adverse effects associated with laser treatment, particularly in dark-skinned individuals. Several methods have been used to prevent or minimize these adverse effects; however, to date, no definitive precautions/strategies are known to prevent post-laser PIH and erythema. We investigated whether the topical application of the α-adrenergic receptor agonist brimonidine could reduce laser treatment-related complications such as erythema...

Novel Use of Brimonidine 0.33% Gel for Hemostasis in Nail Surgery.


To describe a case of neovascular glaucoma from cytomegalovirus (CMV) retinitis in a human immunodeficiency virus-negative patient with immunosuppression after stem-cell transplant for multiple myeloma.


Persistent hyperplastic primary vitreous (PHPV) is a developmental anomaly in which the normal regression of the primary vitreous and hyaloid vasculature does not occur. In the literature, there are a few cases of PHPV in adulthood. We report the novel presentation of phacoanaphylactic glaucoma secondary to posterior capsular rupture in an adult with PHPV. We discuss the best management of this condition with a review of the literature on this topic.

Fifteen Minute Test May Save 15% or More on Rosacea Treatment.

Rosacea is a common inflammatory skin condition that impacts a large portion of fair-skinned populations. The redness associated with rosacea can be a significant challenge. Brimonidine sulfate and oxymetazoline HCL were both recently approved by the FDA for the management of facial redness. These agents, however, are costly, and not all patients respond to the medication. Herein, we describe a clinical pearl that helps to optimize patient selection for the medications. This saves the patient and the health...
