The treatment of glaucoma in and around pregnancy offers the unique challenge of balancing the risk of vision loss to the mother as against the potential harm to the fetus or newborn. Most anti-glaucoma drugs (i.e. beta-blockers, prostaglandin analogues, carbonic anhydrase inhibitors topical and systemic, cholinergics, anticholinesterases, and apraclonidine) are considered category C agents and ophthalmologists are usually limited to treating patients with the category B drugs of brimonidine and dipivefrin...

BACKGROUND: Ptosis after botulinum toxin injection is a disturbing complication. Decongestant and antiglaucoma eyedrops are frequently prescribed for temporary improvement of eyelid ptosis. Although frequently cited on informal communications, the effect of these drugs on eyelid position has never been compared in a formal study. OBJECTIVE: To measure the effect of low-concentration, nonmydriatic selective alpha agonist eyedrops on upper eyelid position. METHODS AND MATERIALS: This nonrandomized clinical trial enrolled 20 healthy subjects aged 18 to 50 years...

The amyloid beta (Aβ) pathway is strongly implicated in neurodegenerative conditions such as Alzheimer's disease and more recently, glaucoma. Here, we identify the α2 adrenergic receptor agonists (α2ARA) used to lower intraocular pressure can prevent retinal ganglion cell (RGC) death via the non-amyloidogenic Aβ-pathway. Neuroprotective effects were confirmed in vivo and in vitro in different glaucoma-related models using α2ARAs brimonidine (BMD), clonidine (Clo) and dexmedetomidine. α2ARA treatment significantly reduced RGC apoptosis in experimental-glaucoma models by 97...

A new ultra-performance liquid chromatography (UPLC) with photodiode array was proposed for the quantitation of Brimonidine Tartrate (BRI) and Timolol Maleate (TIM) in eye drop using experimental design and optimization methodology. A 3(3) full factorial design was applied to uncover the effects of the selected factors and their interactions on the chromatographic response function for the optimization of experimental conditions in the development of a new UPLC method. As a result, the optimal chromatographic conditions giving a better separation and short analysis time were found to be 49...

Although there is presently no cure for rosacea, there are several recommended treatment options available to control many of the symptoms and to prevent them from getting worse. In addition to self-help measures like avoidance of trigger factors and proper skin care, rosacea management should include topical medications as one of the first-line choices for patients with erythematous and mild to severe papulopustular rosacea. Since mixed forms of characteristic rosacea symptoms are more common, medical treatment must be symptom-tailored for each individual case and will often involve a combination therapy...

Obwohl bislang für die Rosazea keine kurative Therapie besteht, können verschiedene Optionen zur Behandlung der Symptome und zur Vorbeugung von Exazerbationen empfohlen werden. Neben Selbsthilfemaßnahme wie der Vermeidung von Triggerfaktoren und einer geeigneten Hautpflege sollte das Rosazea-Management bei Patienten mit erythematöser und leichter bis schwerer papulopustulöser Rosazea die Anwendung topischer Präparate als First-Line-Therapie umfassen. Da Überlappungen der charakteristischen Rosazea-Symptome im klinischen Alltag die Regel sind, sollte die medikamentöse Therapie auf die individuellen Symptome zugeschnitten werden; auch eine Kombinationstherapie kann erforderlich sein...

PURPOSE: Several studies showed that repeated topical administration of brimonidine tartrate ophthalmic solution reached the human vitreous concentration above 2 nM, which is the concentration necessary to activate the α2-adrenergic receptor. The purpose of this study was to elucidate the relationship of the brimonidine concentration in the vitreous body to the free concentration in the retina/choroid which is the target site of brimonidine on neuroprotective effect after topical administration...

BACKGROUND: Rosacea is a chronic inflammatory skin condition associated with four distinct subtypes: erythematotelangiectatic, papulopustular, phymatous, and ocular. PURPOSE: To review the different kinds of management for all subtypes. METHODS: We divided rosacea management into three main categories: patient education, skin care, and pharmacological/procedural interventions. RESULTS: Flushing is better prevented rather than treated, by avoiding specific triggers, decreasing transepidermal water loss by moisturizers, and blocking ultraviolet light...

Ocular drug delivery through hydrogel contact lenses has great potential for the treatment of ocular diseases. Previous studies showed that the loading of lipophilic vitamin E to silicone-hydrogel contact lenses was beneficial in ocular drug delivery. We hypothesized that vitamin E loading to another type of popular hydrogel contact lenses, pHEMA-hydrogel contact lenses, improves ocular drug delivery by increasing the drug loading or the duration of drug release. Loading of vitamin E to pHEMA-hydrogel contact lenses significantly increased the loading of a hydrophilic drug surrogate (Alexa Fluor 488 dye) and two hydrophilic glaucoma drugs (timolol and brimonidine) to the lenses by 37...

Rosacea is a chronic inflammatory disease that can present with a variety of cutaneous symptoms. Erythematotelangiectatic rosacea is a subtype characterized by flushing (transient erythema), persistent central facial erythema (background erythema), and telangiectasias. The severity of individual symptoms differs in each patient, which can complicate the selection of an appropriate treatment strategy. Evaluation of these specific symptoms has been greatly improved by the routine use of diagnostic tools such as (video) dermatoscopy...

Rosacea is a chronic inflammatory disease that can manifest as a spectrum of symptoms including erythema, inflammatory lesions, edema, and telangiectasia. Treatment decisions need to be adapted to reflect the nature and severity of the different symptoms present. In this report, we discuss the case of a female patient diagnosed with severe, inflamed papulopustular rosacea (PPR) presenting with a large number of inflammatory lesions and severe background erythema. This patient responded well to a treatment regimen consisting of a short course of antibiotics in combination with a corticosteroid, followed by monotherapy with isotretinoin to reduce the inflammation...

Core-shell polymer microspheres with poly(d,l-lactic-co-glycolic acid) core and poly(l-lactic acid) (PLLA) shell are developed for the long-term subconjunctival release of brimonidine tartrate (BT) in order to reduce intraocular pressure (IOP) in the treatment of glaucoma. The PLLA-rich shell acts as a diffusion barrier, enabling linear release of BT over an extended period of 40 d. The microspheres are encased in a porous non-degradable methacrylate-based carrier for ease of subconjunctival implantation in a glaucoma-induced rabbit model...

We have studied the effect of α2-adrenergic receptor stimulation on the total excitotoxically injured chicken retinal ganglion cell population. N-methyl-D-aspartate (NMDA) was intraocularly injected at embryonic day 18 and Brn3a positive retinal ganglion cells (Brn3a+ RGCs) were counted in flat-mounted retinas using automated routines. The number and distribution of the Brn3a+ RGCs were analyzed in series of normal retinas from embryonic day 8 to post-hatch day 11 retinas and in retinas 7 or 14 days post NMDA lesion...

: Rosacea is a chronic inflammatory disease with transient and non-transient redness as key characteristics. Brimonidine is a selective α2-adrenergic receptor (AR) agonist approved for persistent facial erythema of rosacea based on significant efficacy and good safety data. The majority of patients treated with brimonidine report a benefit; however, there have been sporadic reports of worsening erythema after the initial response. A group of dermatologists, receptor physiology, and neuroimmunology scientists met to explore potential mechanisms contributing to side effects as well as differences in efficacy...

AIMS: Diabetic retinopathy is considered a microvascular disease, but recent evidence has underlined early involvement of the neuroretina with interactions between microvascular and neural alterations. Topical administration of somatostatin (SST), a neuroprotective molecule with antiangiogenic properties, prevents diabetes-induced retinal neurodegeneration in animals. The α2-adrenergic receptor agonist brimonidine (BRM) decreases vitreoretinal vascular endothelial growth factor and inhibits blood-retinal barrier breakdown in diabetic rats...

Rosacea is a chronic skin disorder associated with flushing, erythema, dryness, burning and stinging, and inflammatory papules and pustules. New treatments available or in development target the inflammatory and erythematous components of the disease. These agents include the selective α2 receptor agonist brimonidine, the topical agents ivermectin cream 1% and azelaic acid foam 15%, and use of tetracyclinetype antibiotics, which affect the cathelicidin pathway.
