Ma Z, Wang Y, He H, Liu T, Jiang Q, Hou X. Advancing ophthalmic delivery of flurbiprofen via synergistic chiral resolution and ion-pairing strategies. Asian J Pharm Sci 2024; 19:100928. [PMID: 38867804 PMCID: PMC11165342 DOI: 10.1016/j.ajps.2024.100928] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Revised: 12/24/2023] [Accepted: 01/16/2024] [Indexed: 06/14/2024] Open
Abstract
Flurbiprofen (FB), a nonsteroidal anti-inflammatory drug, is widely employed in treating ocular inflammation owing to its remarkable anti-inflammatory effects. However, the racemic nature of its commercially available formulation (Ocufen®) limits the full potential of its therapeutic activity, as the (S)-enantiomer is responsible for the desired anti-inflammatory effects. Additionally, the limited corneal permeability of FB significantly restricts its bioavailability. In this study, we successfully separated the chiral isomers of FB to obtain the highly active (S)-FB. Subsequently, utilizing ion-pairing technology, we coupled (S)-FB with various counter-ions, such as sodium, diethylamine, trimethamine (TMA), and l-arginine, to enhance its ocular bioavailability. A comprehensive evaluation encompassed balanced solubility, octanol-water partition coefficient, corneal permeability, ocular pharmacokinetics, tissue distribution, and in vivo ocular anti-inflammatory activity of each chiral isomer salt. Among the various formulations, S-FBTMA exhibited superior water solubility (about 1-12 mg/ml), lipid solubility (1< lg Pow < 3) and corneal permeability. In comparison to Ocufen®, S-FBTMA demonstrated significantly higher in vivo anti-inflammatory activity and lower ocular irritability (such as conjunctival congestion and tingling). The findings from this research highlight the potential of chiral separation and ion-pair enhanced permeation techniques in providing pharmaceutical enterprises focused on drug development with a valuable avenue for improving therapeutic outcomes.

Abstract
PURPOSE Dry eye disease (DED) is a prevalent ocular surface disease that is conventionally characterized by tear film hyperosmolarity and instability. This review presents a summarized classification of DED, followed by a comprehensive discussion of the most recent topical and systemic medications and clinical recommendations for selecting the most appropriate option for each patient. METHODS An extensive literature search was conducted on electronic databases, such as PubMed, Scopus, and Web of Science, using keywords including "dry eye syndrome," "ocular surface disease," "medical management," "artificial tears," "topical immunomodulators," and "meibomian gland dysfunction." RESULTS The underlying reasons for DED can range from insufficient aqueous tear production to increased tear evaporation. Recent literature has provided a more in-depth understanding of the pathophysiology of DED by examining the tear film's lipid, aqueous, and mucin layers. However, despite these advancements, medical management of patients with symptomatic DED has not fully reflected this modernized knowledge of its pathophysiology. CONCLUSION To develop a rationalized strategy for treating DED, it is crucial to have updated knowledge of therapeutic options, their mechanisms of actions, and indications based on the DED type and underlying causes.

Abstract
INTRODUCTION Cataract surgery is becoming more common due to an aging world population. Intraocular lenses and surgical technique have developed remarkably recently, but the development of postoperative medication to prevent postsurgery complications has been relatively delayed. We still largely depend on eye drops for the management of post-cataract-surgery patients. Mental and physical problems that often occur in elderly cataract patients make it difficult for patients to apply eye drops by themselves. It is necessary to develop new effective drug delivery methods. AREAS COVERED This updated review article provides a brief review of why drug management is needed following cataract surgery and an overview of current developments in new drug delivery methods for ophthalmic treatment. In particular, various novel drug delivery methods that can be used for post-cataract-surgery management and their current development stages are extensively reviewed. EXPERT OPINION Rapidly developing technologies, such as intraocular and external ophthalmic implants, polymers, and nanotechnology, are being actively applied to develop novel drug delivery systems for safe and effective management after cataract surgery. Their goal is to achieve sufficient drug release for the desired duration with a single application. These will largely replace the inconvenience of eye drops for elderly patients in the future.

Abstract
Dimethyl sulfoxide (DMSO) is an amphipathic molecule widely used as a solvent for water-insoluble substances, cryopreserving, and cell-biological therapies. It has known properties as an inducer of cellular differentiation, a free radical scavenger, and a radioprotectant. In addition, DMSO is used for its various therapeutic and pharmaceutical properties, such as anti-inflammatory, local and systemic analgesic, antibacterial, antifungal, antiviral, and membrane penetration enhancement agents. DMSO treatment can be given orally, intravenously, or topically for a wide range of indications. The administration of DMSO exhibits favorable outcomes in human eye diseases with low to none observed ocular or systemic ocular toxicity. Nevertheless, DMSO is an essential and nonpatentable potential therapeutic agent that remains underexplored and ignored by pharmaceutical developers and ophthalmologists. This current review takes data from experimental and clinical studies that have been published to substantiate the potential therapeutic efficacy of DMSO and stimulate the research of its application in clinical ophthalmology. Given that DMSO is inexpensive, safe, and easily formulated into therapeutic medicinal products and conventional ophthalmological drugs, this compound should be further explored and studied in the treatment of a variety of acute and chronic ocular disorders.

Abstract
PURPOSE To develop a mesoporous silica drug delivery system and target drop-free care after cataract surgery with a single subconjunctival injection. SETTING Laboratory. DESIGN Experimental animal study. METHODS Ketorolac was infiltration-loaded into sol-gel mesoporous silica particles encapsulated with poly(allylamine hydrochloride) and poly(sodium 4-styrenesulfonate) using a layer-by-layer adsorption technique (SG-Ket-LBL). The formulation was subjected to an in vitro and in vivo drug release study in addition to ocular toxicology evaluation. RESULTS Thermogravimetric analysis revealed that the drug loading efficiency was 4.4% for the SG-Ket-LBL particles. The in vivo safety study demonstrated that the formulation was well tolerated after subconjunctival injection and aqueous humor pharmacokinetics showed sustained therapeutic drug release for the targeted time window of 6 to 8 weeks. CONCLUSIONS Findings indicated that sol-gel mesoporous silica could be used as a drug carrier for subconjunctival administration. The tested formulation, SG-Ket-LBL, provided therapeutic ketorolac for 6 to 8 weeks, which might be used for a single subconjunctival injection to replace nonsteroidal anti-inflammatory drug eyedrops after cataract surgery.

Abstract
Ocular inflammation is one of the most common symptom of eye disorders and diseases. The therapeutic management of this inflammation must be rapid and effective in order to avoid deleterious effects for the eye and the vision. Steroidal (SAID) and non-steroidal (NSAID) anti-inflammatory drugs and immunosuppressive agents have been shown to be effective in treating inflammation of the ocular surface of the eye by topical administration. However, it is well established that the anatomical and physiological ocular barriers are limiting factors for drug penetration. In addition, such drugs are generally characterized by a very low aqueous solubility, resulting in low bioavailability as only 1% to 5% of the applied drug permeates the cornea. The present review gives an updated insight on the conventional formulations used in the treatment of ocular inflammation, i.e., ointments, eye drops, solutions, suspensions, gels, and emulsions, based on the commercial products available on the US, European, and French markets. Additionally, sophisticated formulations and innovative ocular drug delivery systems will be discussed. Promising results are presented with micro- and nanoparticulated systems, or combined strategies with polymers and colloidal systems, which offer a synergy in bioavailability and sustained release. Finally, different tools allowing the physical characterization of all these delivery systems, as well as in vitro, ex vivo, and in vivo evaluations, will be considered with regards to the safety, the tolerance, and the efficiency of the drug products.

Abstract
PURPOSE To compare the efficacy of nepafenac on anterior chamber flare and intraocular pressure(IOP) in healthy (group 1) and uveitic eyes (group 2) undergoing cataract surgery. METHODS A retrospective, consecutive case series study. RESULTS Among 54 the patients, 14 had a history of uveitis. The groups were similar in age and gender. There were significant changes in flare values in both groups. When the temporal changes of flare values were compared, there was no difference between the two groups. There were no significant changes in IOP values in both group. When the temporal changes of IOP values were compared, there was no difference between the groups. CONCLUSIONS Nepafenac 0.1% has been shown to be effective in suppressing inflammation after cataract surgery in uveitic eyes as well as in healthy eyes. In addition, it has been observed that it does not increase intraocular pressure in both healthy and uveitic eyes and it is safe to use with this regard.

Abstract
Since their first introduction in ophthalmology, the use of NSAIDs (nonsteroidal anti-inflammatory drugs) has been exponentially expanded, with numerous therapeutic applications. Despite their controversial history, they have proven their efficacy as anti-inflammatory agents in a variety of diseases. Nowadays, NSAIDs are part of surgical protocols of the most commonly performed ophthalmic operations, such as cataract or ocular surgery. They are universally implicated in the management of conjunctivitis, retinal and choroidal disease and miscellaneous inflammatory diseases. Moreover, although linked with serious adverse events and toxicities, their therapeutic magnitude in Ophthalmology should not be affected. This review systematically portrays the variety of ocular NSAIDs available to date, along with their differences in their way of action, indications and potential side effects in various ophthalmologic conditions.

Abstract
PURPOSE To evaluate the effect of preoperative 0.09% bromfenac ophthalmic solution for the reduction of intraoperative miosis and pain in patients who have undergone femtosecond laser-assisted cataract surgery. METHODS This prospective randomized clinical study included 65 patients with senile cataracts in the absence of significant ocular comorbidity. The patients received 0.09% bromfenac ophthalmic solution or control placebo twice a day for 3 days before surgery. Pupil diameter was measured at the initiation and finalization of femtosecond laser-assisted cataract surgery, and pain quantification was assessed by an analogous pain scale after one day of follow-up. RESULTS A total of 65 patients were randomly divided into two groups. Five patients were excluded due to defective coupling with the laser interface. Each of the 60 patients was randomized to receive preoperative topical treatment with either 0.09% bromfenac or 0.1% sodium hyaluronate. Baseline characteristics were similar between groups for age and gender. The mean change in horizontal and vertical pupil diameter from the preoperative to post-femtosecond laser measurements were significantly less in the bromfenac group than in the placebo group (0.43 ± 0.6 vs. 1.71 ± 0.9, P < 0.001 and 0.40 ± 0.6 vs. 1.78 ± 0.9, P < 0.001, respectively). Compared with untreated patients, the quantification of pain one day after the procedure was significantly lower in the 0.09% bromfenac group (46.7% with a score of 3 vs. 50% with a score of 1, P < 0.001, respectively). CONCLUSIONS The maintenance of pupil dilation and the prevention of miosis were more effective in the 0.09% bromfenac group than in the control group. Likewise, the greater control of postoperative pain represented an additional significant benefit.

Abstract
Importance Trustworthy clinical practice guidelines require reliable systematic reviews of the evidence to support recommendations. Since 2016, the American Academy of Ophthalmology (AAO) has partnered with Cochrane Eyes and Vision US Satellite to update their guidelines, the Preferred Practice Patterns (PPP). Objective To describe experiences and findings related to identifying reliable systematic reviews that support topics likely to be addressed in the 2016 update of the 2011 AAO PPP guidelines on cataract in the adult eye. Design, Setting, and Participants Cross-sectional study. Systematic reviews on the management of cataract were searched for in an established database. Each relevant systematic review was mapped to 1 or more of the 24 management categories listed under the Management section of the table of contents of the 2011 AAO PPP guidelines. Data were extracted to determine the reliability of each systematic review using prespecified criteria, and the reliable systematic reviews were examined to find whether they were referenced in the 2016 AAO PPP guidelines. For comparison, we assessed whether the reliable systematic reviews published before February 2010 the last search date of the 2011 AAO PPP guidelines were referenced in the 2011 AAO PPP guidelines. Cochrane Eyes and Vision US Satellite did not provide systematic reviews to the AAO during the development of the 2011 AAO PPP guidelines. Main Outcomes and Measures Systematic review reliability was defined by reporting eligibility criteria, performing a comprehensive literature search, assessing methodologic quality of included studies, using appropriate methods for meta-analysis, and basing conclusions on review findings. Results From 99 systematic reviews on management of cataract, 46 (46%) were classified as reliable. No evidence that a comprehensive search had been conducted was the most common reason a review was classified as unreliable. All 46 reliable systematic reviews were cited in the 2016 AAO PPP guidelines, and 8 of 15 available reliable reviews (53%) were cited in the 2011 PPP guidelines. Conclusions and Relevance The partnership between Cochrane Eyes and Vision US Satellite and the AAO provides the AAO access to an evidence base of relevant and reliable systematic reviews, thereby supporting robust and efficient clinical practice guidelines development to improve the quality of eye care.

Abstract
The treatment and management of ocular allergy (OA) remain a major concern for different specialties, including allergists, ophthalmologists, primary care physicians, rhinologists, pediatricians, dermatologists, clinical immunologists, and pharmacists. We performed a systematic review of all relevant publications in MEDLINE, Scopus, and Web Science including systematic reviews and meta-analysis. Publications were considered relevant if they addressed treatments, or management strategies of OA. A further wider systematic literature search was performed if no evidence or good quality evidence was found. There are effective drugs for the treatment of OA; however, there is a lack an optimal treatment for the perennial and severe forms. Topical antihistamines, mast cell stabilizers, or double-action drugs are the first choice of treatment. All of them are effective in reducing signs and symptoms of OA. The safety and optimal dosing regimen of the most effective topical anti-inflammatory drugs, corticosteroids, are still a major concern. Topical calcineurin inhibitors may be used in steroid-dependent/resistant cases of severe allergic keratoconjunctivitis. Allergen-specific immunotherapy may be considered in cases of failure of first-line treatments or to modify the natural course of OA disease. Based on the current wealth of publications and on the collective experience, recommendations on management of OA have been proposed.

[PMID: 31534309 PMCID: PMC6682171 DOI: 10.2147/opth.s208700] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2019] [Accepted: 06/27/2019] [Indexed: 01/20/2023] Open
Abstract
Topical ophthalmic nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat postoperative inflammation and pain following cataract surgery and for treatment and prophylaxis of pseudophakic cystoid macular edema (CME). Bromfenac is a brominated NSAID with strong in vitro anti-inflammatory potency. Like other ophthalmic NSAIDs, bromfenac is often used outside of the cataract surgery setting. This paper provides an overview of bromfenac’s preclinical ocular pharmacology and pharmacokinetics, followed by a review of 23 published clinical studies in which various marketed bromfenac formulations were used for conditions other than cataract surgery or pseudophakic CME. These include: post-refractive eye surgery; macular edema associated with diabetes, uveitis, or retinal vein occlusion; inflammation associated with age-related macular degeneration; pain related to intravitreal injections; and other ocular anterior segment and surface disorders with an inflammatory component. The published evidence reviewed supports the safety and effectiveness of bromfenac in these additional ophthalmic indications. Bromfenac was well tolerated when given alone or in combination with intravitreal anti-vascular endothelial growth factor agents, topical corticosteroids, or topical mast-cell stabilizers. The most common adverse event reported was ocular irritation. No serious adverse events (ie, corneal epithelial disorders) were reported, although the majority of studies did not systematically evaluate potential side effects. Corneal complications, such as melts reported with diclofenac and ketorolac, were not observed with bromfenac in the studies. In summary, published study data support the clinical utility of bromfenac in various ocular disorders beyond post-cataract surgery. Additional studies are warranted to further define the potential role of bromfenac ophthalmic solution in clinical practice.

Pain Control after Intravitreal Injection Using Topical Nepafenac 0.3% or Pressure Patching: A Randomized, Placebo-Controlled Trial. Ophthalmol Retina 2019; 3:860-866. [PMID: 31221565 DOI: 10.1016/j.oret.2019.04.022] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Revised: 04/20/2019] [Accepted: 04/22/2019] [Indexed: 11/26/2022]
Abstract
PURPOSE Pain after an intravitreal injection (IVI) can last up to 7 days and negatively impacts the patient's experience, potentially reducing treatment compliance. We prospectively evaluated topical nepafenac 0.3% suspension and patching for the reduction of pain after IVI. DESIGN Randomized controlled trial. PARTICIPANTS Sixty patients receiving an IVI of bevacizumab, aflibercept, or triamcinolone acetonide in 1 eye. METHODS Participants were randomized equally to receive either a single drop of nepafenac 0.3%, a pressure patch for 2 hours, or a single drop of preservative-free artificial tears (control group). A single-blinded placebo-controlled design was used to mask the topical treatment used. Pain was assessed using the Numeric Pain Rating Scale that ranged from 0 to 10 (horizontal pain scale). Because pain scores were not normally distributed, statistical analysis was performed using a nonparametric randomization-based analysis of covariance. MAIN OUTCOME MEASURE Pain scores. RESULTS Fifty-six and 53 patients of the 60 patients enrolled completed the 6- and 24-hour follow-ups, respectively. Numeric Pain Rating Scale scores at 6 and 24 hours after IVI were lower in the nepafenac group (0.8±0.3 and 0.1±0.1, respectively; n = 18) and the patching group (1.3±0.4 and 0.4±0.2, respectively; n = 19) compared with the control group (2.5±0.6 and 0.9±0.4, respectively; n = 19). After controlling for age, gender, number of prior injections, and physician administering the injection, patients in the nepafenac group reported significantly lower pain scores than those in the control group at 6 hours (1.3±0.6 less; P = 0.047) and 24 hours (0.7±0.3 less; P = 0.047). Although the patching group reported lower pain scores than the control group, this was not statistically significant (6 hours, P = 0.24; 24 hours, P = 0.29). CONCLUSIONS Nepafenac 0.3% was effective as a single drop in reducing pain at 6 and 24 hours after IVI compared with placebo. Limited patching was associated with lower pain scores than placebo, but the difference was not statistically significant. Additional studies are needed to determine the most effective method to maximize the patient's experience after an IVI without sacrificing outcomes.

Abstract
Purpose SLC4A11 is a plasma membrane protein of corneal endothelial cells. Some mutations of the SLC4A11 gene result in SLC4A11 protein misfolding and failure to mature to the plasma membrane. This gives rise to some cases of Fuchs' endothelial corneal dystrophy (FECD) and congenital hereditary endothelial dystrophy (CHED). We screened ophthalmic nonsteroidal anti-inflammatory drugs (NSAIDs) for their ability to correct SLC4A11 folding defects. Methods Five ophthalmic NSAIDs were tested for their therapeutic potential in some genetic corneal dystrophy patients. HEK293 cells expressing CHED and FECD-causing SLC4A11 mutants were grown on 96-well dishes in the absence or presence of NSAIDs. Ability of NSAIDs to correct mutant SLC4A11 cell-surface trafficking was assessed with a bioluminescence resonance energy transfer (BRET) assay and by confocal microscopy. The ability of mutant SLC4A11-expressing cells to mediate water flux (SLC4A11 mediates water flux across the corneal endothelial cell basolateral membrane as part of the endothelial water pump) was measured upon treatment with ophthalmic NSAIDs. Results BRET-assays revealed significant rescue of SLC4A11 mutants to the cell surface by 4 of 5 NSAIDs tested. The NSAIDs, diclofenac and nepafenac, were effective in moving endoplasmic reticulum-retained missense mutant SLC4A11 to the cell surface, as measured by confocal immunofluorescence. Among intracellular-retained SLC4A11 mutants, 20 of 30 had significant restoration of cell surface abundance upon treatment with diclofenac. Diclofenac restored mutant SLC4A11 water flux activity to the level of wild-type SLC4A11 in some cases. Conclusions These results encourage testing diclofenac eye drops as a treatment for corneal dystrophy in patients whose disease is caused by some SLC4A11 missense mutations.

Abstract
Challenges in the management of ocular pain are an underappreciated topic. Currently available therapeutics lack both efficacy and clear guidelines for their use, with many also possessing unacceptable side effects. Promising novel agents would offer analgesic, anti-inflammatory, and possibly neuroprotective actions; have favorable ocular safety profiles; and show potential in managing neuropathic pain. Growing evidence supports a link between the endocannabinoid system (ECS) and a range of physiological and disease processes, notably those involving inflammation and pain. Both preclinical and clinical data suggest analgesic and anti-inflammatory actions of cannabinoids and ECS-modifying drugs in chronic pain conditions, including those of neuropathic origin. This review will examine existing evidence for the anatomical and physiological basis of ocular pain, specifically, ocular surface disease and the development of chronic ocular pain. The mechanism of action, efficacy, and limitations of currently available treatments will be discussed, and current knowledge related to ECS-modulation of ocular pain and inflammatory disease will be summarized. A perspective will be provided on the future directions of ECS research in terms of developing cannabinoid therapeutics for ocular pain.

Abstract
The conjunctiva is a common site for the allergic inflammatory response due to it being highly vascularized, having constant exposure to environmental pollutants and allergenic pollens and having a unique conjunctival associated lymphoid tissue. The primary morbidity of anterior surface conjunctival disorders that include allergic conjunctivitis and tear film disorders is associated with its high frequency of involvement rather than its severity, although the more chronic forms can involve the cornea and lead to sight-threatening conditions. Ocular allergy is associated with IgE-mediated mast cell activation in conjunctival tissue leading to the release of preformed mediators including histamine and proteases and subsequent de novo formation of lipid-derived mediators and cytokines that trigger a cascade of cellular and molecular events leading to extensive migration and infiltration of inflammatory cells to the ocular surface. The trafficking of neutrophils, eosinophils, and lymphocytes to the ocular surface is due to establishing various chemokine gradients (mainly CCL11, CCL24, CCL5, MCP-3, and MCP-4), cell surface expression of adhesion molecules (such as VCAM-1 the ligand for VLA-4), and leukocyte adhesion to vascular endothelium. The release of preformed mediators underlies the acute ocular surface response while the secondary influx of inflammatory cells leading to the recruitment and activation of eosinophils and the subsequent activation of Th2 and Th1 lymphocytes at the level of the conjunctiva reflects the late-phase reaction.

Abstract
PURPOSE OF REVIEW The update reviews prevalence, classification, cause, and treatment options for allergic eye disease. RECENT FINDINGS The incidence of allergic eye disease is underreported but may affect almost all patients with allergic rhinitis. Increased rates of oculonasal symptoms have been reported in the United States resulting in significant economic expenditures. The spectrum of allergic conjunctivitis and its differential considerations include seasonal and perennial conjunctivitis, vernal and atopic keratoconjunctivitis, and giant papillary conjunctivitis. Patients with allergic conjunctivitis have classic immunoglobulin E-mediated pathophysiology and treatments directed at allergen avoidance, traditional pharmacotherapy with oral antihistamines, topical dual-acting antihistamine/mast cell stabilizer agents, and treatment of tear film dysfunction are first-line management strategies. Immunotherapy is an effective treatment option and refractory cases may require ophthalmology comanagement for consideration of topical ester-based corticosteroid therapy and consideration of topical immunomodulators. SUMMARY Ocular allergy involving specific modifiable and treatable environmental sensitizations is common and often underrecognized. It can impair quality of life to varying degrees. Some cases are quite refractory to management and may require multidisciplinary coordination of care between allergy and ophthalmology specialists. Understanding classification, triggers, and treatment options is important in designing the most appropriate patient-tailored management plans.

Abstract
Purpose To describe nepafenac use in the Netherlands and Denmark with reference to its approved indications. For context, we also describe the use of ketorolac and diclofenac. Methods We identified users in the PHARMO Database Network (the Netherlands, 2008–2013) and the Danish national health registers (Denmark, 1994–2014). We described prevalence of cataract surgery and duration of use in patients with cataract surgery with and without diabetes. Results In the Netherlands, 9530 nepafenac users (mean age, 71 years; 60% women) contributed 12 691 therapy episodes, of which 21% had a recently recorded cataract surgery. Of 2266 episodes in adult non‐diabetic patients with cataract surgery, 60% had one bottle dispensed (treatment duration ≤21 days). Of 441 episodes in adult diabetic patients with cataract surgery, 90% had up to two bottles dispensed (≤60 days). Denmark had 60 403 nepafenac users (mean age, 72 years; 58% women) and 73 648 episodes (41% had recorded cataract surgery). Of 26 649 nepafenac episodes in adult non‐diabetic patients with cataract surgery, 92% had one bottle dispensed. Of 3801 episodes in adult diabetic patients with cataract surgery, 99.8% had up to two bottles dispensed. Use patterns of nepafenac, ketorolac and diclofenac were roughly similar in the Netherlands, but not in Denmark. Conclusion Less than half of therapy episodes were related to cataract surgery; around 90% of episodes with surgery were within the approved duration. Underrecording of ophthalmic conditions and procedures was a challenge in this study.

Abstract
PURPOSE To evaluate the analgesic effect of bromfenac, a topically administered nonsteroidal antiinflammatory agent, in patients undergoing intravitreal injections (IVIs) of anti-vascular endothelial growth factor agents. METHODS A single center, prospective, randomized, double-blind, placebo-controlled, cross over interventional study. Patients scheduled to undergo IVI of anti-vascular endothelial growth factor were randomized to receive topical bromfenac or placebo before IVI. Pain perception was assessed using the short form of the McGill Pain Questionnaire. Pain intensity was evaluated with the visual analog scale, the main component of the short form of the McGill Pain Questionnaire, and the Present Pain Intensity scores immediately and 6 hours postinjection. RESULTS Sixty-five patients (65 eyes) were enrolled in the study. Immediately after IVI, pain perception was statistically significant lower in patients treated with bromfenac compared with placebo as assessed by the visual analog scale pain score and the main component of the short form of the McGill Pain Questionnaire (P = 0.002 and 0.001, respectively). At 6 hours postIVI, pain was statistically significant lower in patients treated with bromfenac, according to the visual analog scale pain score, the main component of the short form of the McGill Pain Questionnaire, and the Present Pain Intensity score (P < 0.001, <0.001, and P = 0.001, respectively). Multivariable regression analysis revealed that pain perception, as evaluated with the visual analog scale pain score immediately after IVI, was significantly lower in patients of older age, female patients and those with higher number of previous injections. Immediately after IVI, bromfenac seemed to be more effective in younger patients and in those who had already undergone an amount of injections. CONCLUSION Topical instillation of bromfenac significantly reduced the IVI-related pain immediately after and 6 hours postinjection.

Abstract
Ocular infection and inflammation are common and are associated with myriad ocular conditions ranging from mild disease to blinding conditions. There are numerous anti-invectives with spectra against inciting pathogens. Given the potential for ocular infections to rapidly progress initial broad spectrum therapy is usually required, with therapy tailored as microbiological identification and sensitivities become available. The emergence of antibiotic resistance has become a major health problem. Anti-inflammatory therapy can be institutes to prevent ocular symptoms and end-organ damage. A therapy should be selected which is potent enough to interrupt the inflammatory cascades in play, but which avoids potential side effects. Glucocorticoids, NSAIDs, and biological agents may be used singularly or in combination. New drug delivery devices may allow for better local treatment of chronic ocular inflammation.

Abstract
Purpose The aim of this study was to evaluate the safety, tolerability, and efficacy of a low-dose version of bromfenac 0.075% in DuraSite® (bromfenac 0.075%) compared with DuraSite® vehicle (vehicle) alone for the treatment of postoperative inflammation and ocular pain after cataract surgery. Methods A multicenter, double-masked, vehicle-controlled, parallel-group clinical trial of 240 subjects randomized in a 2:1 ratio to bromfenac 0.075% or vehicle was conducted. Subjects were dosed BID beginning 1 day before the cataract surgery, the day of surgery, and 14 days after surgery. A slit lamp biomicroscopy examination was performed to evaluate the signs of inflammation, including anterior chamber cells (ACC) and anterior chamber flare (ACF). The primary efficacy variable was the proportion of subjects with an ACC grade of 0 at Day 15. Secondary efficacy endpoints included the proportion of subjects who achieved a pain score of 0 at each postsurgical visual analog scale (VAS) assessment and the proportion of subjects with an ACF grade of 0 at Day 15. Results At Day 15, proportionally more subjects in the bromfenac 0.075% group than in the vehicle group had an ACC grade of 0 (57.1% vs 18.8%, respectively; P<0.001). At each of the postsurgical time points (Days 1, 8, 15, and 29), proportionally more bromfenac 0.075%-treated subjects (76.8%, 90.5%, 92.9%, and 85.1%, respectively) had no pain (a VAS score of 0) compared with the vehicle-treated subjects (48.2%, 38.8%, 42.4%, and 47.1%, respectively), and at each time point, these differences in proportions were statistically significant (P<0.001). More subjects in the bromfenac 0.075% group had complete ACF resolution (151/167; 90.4%) compared to those in the vehicle group (54/85; 63.5%). There were no new safety signals reported. Conclusion Bromfenac 0.075% in DuraSite is safe, well tolerated, and effective at reducing inflammation and preventing pain associated with cataract surgery.

Abstract
Cataract, a degradation of the optical quality of the crystalline lens, progressive and age-related, is the leading cause of treatable blindness worldwide. Cataract surgery is the most common surgical procedure performed by ophthalmologists and is the only effective treatment for cataracts. Advances in the surgical techniques and better postoperative visual outcomes have progressively changed the primary concern of cataract surgery to become a procedure refined to yield the best possible refractive results. Sufficient mydriasis during cataract removal is critical to a successful surgical outcome. Poor pupil dilation can lead to serious sight-threatening complications that significantly increase the cost of surgery and decrease patients comfort. Mydriasis is obtained using anticholinergic and sympathomimetic drugs. Phenylephrine, an α1-adrenergic receptor agonist, can efficiently dilate the pupil when administered by intracameral injection. Additionally, nonsteroidal anti-inflammatory drugs (NSAIDs) like ketorolac, which inhibit the synthesis of prostaglandins, are used to decrease intraoperative miosis, control pain and inflammation associated with cataract surgery, and to prevent the development of cystoid macular edema following surgery. Recently, a new combination of phenylephrine and ketorolac (Omidria®) has been approved by United States Food and Drug Administration for use during cataract surgery to maintain intraoperative mydriasis, prevent miosis, and reduce postoperative pain and inflammation. Clinical trials have shown that this new combination is effective, combining the positive effects of both drugs with a good safety profile and patient tolerability. Moreover, recent reports suggest that this combination is also effective in patients with high risk of poor pupil dilation. In conclusion, cataract is a global problem that significantly affects patients' quality of life. However, they can be managed with a safe and minimally invasive surgery. Advances in surgical techniques and newer pharmacological agents such as the combination of phenylephrine and ketorolac, together with better intraocular lenses, have greatly improved visual outcomes and thus patients' expectations regarding visual recovery are also increasing.
