Pharmacology, safety, efficacy and clinical uses of the COX-2 inhibitor robenacoxib.

Robenacoxib is a veterinary-approved non-steroidal anti-inflammatory drug (NSAID) of the coxib group. It possesses anti-hyperalgesic, anti-inflammatory and anti-pyretic properties. Robenacoxib inhibits the cyclooxygenase (COX)-2 isoform of COX selectively (in vitro IC50 ratios COX-1:COX-2, 129:1 in dogs, 32:1 in cats). At registered dosages (2 mg/kg subcutaneously in dogs and cats, 1-4 mg/kg orally in dogs and 1-2.4 mg/kg orally in cats), robenacoxib produces significant inhibition of COX-2 whilst sparing COX-1. The pharmacokinetic (PK) profile of robenacoxib is characterized by a high degree of binding to plasma proteins (>98%) and moderate volume of distribution (at steady state, 240 ml/kg in dogs and 190 ml/kg in cats). In consequence, the terminal half-life in blood (<2 h) is short, despite moderate body clearance (0.81 L/kg/h) in dogs and low clearance (0.44 L/kg/h) in cats. Excretion is principally in the bile (65% in dogs and 72% in cats). Robenacoxib concentrates in inflamed tissues, and clinical efficacy is achieved with once-daily dosing, despite the short blood terminal half-life. In dogs, no relevant breed differences in robenacoxib PK have been detected. Robenacoxib has a wide safety margin; in healthy laboratory animals daily oral doses 20-fold (dog, 1 month), eight-fold (cat, 6 weeks) and five-fold (dog, 6 months) higher than recommended clinical doses were well tolerated. Clinical efficacy and safety have been demonstrated in orthopaedic and soft tissue surgery, and in musculoskeletal disorders in dogs and cats.

Nepafenac in cataract surgery.

The role of topical non-steroidal anti-inflammatory drugs (NSAIDs) in routine cataract surgery has been established since decades. Topical NSAIDs have been shown to reduce postoperative ocular inflammation and pain, preserve intraoperative mydriasis, and reduce the risk of postoperative cystoid macular oedema, whilst carrying a very low side-effect profile. Nepafenac is one of the currently available topical NSAIDs. The studies have shown that is has a high ocular penetration, allowing for potentially better results than other NSAIDs. This review gathers the current literature on the role of nepafenac in cataract surgery aiming to help surgeons maximise the benefits of its use to achieve improved surgical outcomes.

Nepafenac for cystoid macular oedema secondary to paclitaxel.

Paclitaxel is used to treat a wide range of malignant tumours. This type of drug is known to cause ocular adverse effects, with cystoid macular oedema being a known, but rare complication, of this therapy. Although most cases resolve after discontinuation of the drug, several authors have attempted various treatments to accelerate resolution, or when paclitaxel therapy cannot be discontinued. A case is presented of a 62 year-old man who presented with decreased visual acuity due to bilateral cystoid macular oedema after administration of paclitaxel for oesophageal cancer. As part of the study, optical coherence tomography angiography (OCTA) was performed at the time of diagnosis, and later when the symptoms subsided. Nepafenac eye drops were prescribed as treatment.

Antiangiogenic properties of lichen secondary metabolites.

Lichens are symbiotic organisms which are composed fungi and algae and/or cyanobacteria. They produce a variety of characteristic secondary metabolites. Such substances have various biological properties including antimicrobial, antiviral, and antitumor activities. Angiogenesis, the growth of new vessels from pre-existing vessels, contributes to numerous diseases including cancer, arthritis, atherosclerosis, infectious, and immune disorders. Antiangiogenic therapy is a promising approach for the treatment of such diseases by inhibiting the new vessel formation. Technological advances have led to the development of various antiangiogenic agents and have made possible antiangiogenic therapy in many diseases associated with angiogenesis. Some lichens and their metabolites are used in the drug industry, but many have not yet been tested for their antiangiogenic effects. The cytotoxic and angiogenic capacities of lichen-derived small molecules have been demonstrated in vivo and in vitro experiments. Therefore, some of them may be used as antiangiogenic agents in the future. The secondary compounds of lichen whose antiangiogenic effect has been studied in the literature are usnic acid, barbatolic acid, vulpinic acid, olivetoric acid, emodin, secalonic acid D, and parietin. In this article, we review the antiangiogenic effects and cellular targets of these lichen-derived metabolites.

Therapeutic Strategies for the Treatment of Chronic Hyperuricemia: An Evidence-Based Update.

This article aims to critically review the evidence on the available therapeutic strategies for the treatment of hyperuricemia. For this reason, several papers were reviewed. Xanthine oxidase inhibitors are the safest and most effective uric acid lowering drugs for the management of chronic hyperuricemia, while the efficacy of uricosuric agents is strongly modulated by pharmacogenetics. Emergent drugs (lesinurad, peglotidase) were found to be more effective for the acute management of refractory hyperuricemia, but their use is supported by a relatively small number of clinical trials so that further well-designed clinical research is needed to deepen their efficacy and safety profile.

Incidence and Outcomes of Cystoid Macular Edema after Descemet Membrane Endothelial Keratoplasty (DMEK) and DMEK Combined with Cataract Surgery.

PURPOSE: To investigate the incidence and outcomes of cystoid macular edema (CME) after Descemet membrane endothelial keratoplasty (DMEK) alone and DMEK combined with cataract surgery (DMEK triple). MATERIALS AND METHODS: A retrospective chart review was performed for patients who underwent DMEK and DMEK triple between January 2014 and March 2018 at two tertiary hospitals. Patients with minimum of 6 months of follow-up were included. Logistic regression analysis was used to identify potential risk factors for CME including gender, age, glaucoma, uveitis, epiretinal membrane, diabetes mellitus, iridotomy, and rebubbling. RESULTS: 09 eyes of 193 patients who underwent DMEK (124 eyes) and DMEK triple (85 eyes) were included. The 6-month incidence of CME was 3.8% (8/209) for all cases, 2.4% (2/85) for DMEK triple, and 4.8% (6/124) for DMEK alone. CME was treated with topical prednisolone acetate 1% and nepafenac four times daily, and/or periocular triamcinolone acetonide, with resolution in all cases. On average, CME was detected 8.9 ± 2.1 weeks postoperatively, with a mean time to resolution of 4.1 ± 1.7 months. The 6-month best-corrected distance visual acuity of eyes that developed CME was not significantly different compared to eyes that did not develop CME (0.17 ± 0.15 logMAR vs. 0.23 ± 0.27 logMAR; p = .76). On logistic regression analysis, no risk factors for developing CME were identified. CONCLUSIONS: The incidence of CME after DMEK was low and not associated with decreased long-term visual acuity. Most cases of CME occurred between 1 and 3 months postoperatively. Predictive factors for CME after DMEK require further study.

Comparison of the Effect of Diclofenac 0.1% and Nepafenac 0.1% on Aqueous Flare in Patients Undergoing Cataract Surgery: A Prospective Randomized Study.

OBJECTIVES: To compare, using laser flare meter (LFM), the efficacy of topical nepafenac 0.1, % and diclofenac 0.1% ophthalmic solution in the control of anterior chamber inflammation after uncomplicated cataract surgery. METHODS: Patients undergoing phacoemulsification for age-related cataract were recruited. Complete evaluation with visual acuity, slit-lamp examination, endothelial cell density, intraocular pressure, retinal tomography and anterior chamber flare evaluation was performed before surgery and 1, 15, 30 and 60 days after surgery. Patients were randomly assigned to receive topical diclofenac 0.1% 4 times a day for four weeks or nepafenac 0.1% 3 times a day for three weeks in addition to topical steroids and antibiotic. RESULTS: 64 (31 males, mean age 77.3 ± 5.9) patients were enrolled. Half of them were randomly assigned to group A (diclofenac 0.1%) and half to group B (nepafenac 0.1%). There was a statistically significant visual acuity improvement postoperatively in both groups, with no statistical difference between the groups. Intraocular pressure, corneal thickness, endothelial cells count and macular thickness parameters didn't significantly vary between before and after surgery. One-day after surgery, aqueous flare was significantly higher (22,27 ± 9,25 ph/ms in group A and 22,36 ± 7,47 in group B) than before surgery (14,59 ± 7,16 ph/ms in group A and 11,84 ± 4,44 in group B) in both groups, then declining in the first month and reaching preoperative levels again by 2 months in both groups. In group B, LFM values at 15 and 30 days after surgery were significantly lower (13,59 ± 4,80 and 14,07 ± 5,01) than in group A (17,00 ± 6,97 and 16,96 ± 6,13). CONCLUSIONS: Nepafenac ensured a better inflammation control than diclofenac during the first month.

Anti-inflammatory Medication of Cataract Surgery in Pseudoexfoliation Syndrome - NSAID Is Needed.

BACKGROUND: To optimize the anti-inflammatory treatment of cataract surgery in pseudoexfoliation syndrome (PXF) eyes. METHODS: A prospective randomized double-masked trial. Sixty eyes of 60 patients with PXF undergoing routine cataract surgery were randomized for potent topical postoperative anti-inflammatory medication either with prednisolone acetate (10mg/ml), nepafenac (1mg/ml) or their combination. Clinical outcome parameters were recorded at 28 days and 3 months. Recovery from surgery was recorded by a structured home questionnaire. RESULTS: Patient age and gender distribution, and all baseline ophthalmic and surgical parameters were comparable between the study groups. At 28 days, change in central subfield macular thickness was +11.4 ± 11.9 µm in prednisolone acetate group compared to +1.7 ± 16.8 µm in nepafenac (P = .017), and -0.3 ± 8.7 µm in combination therapy (P = .010) groups. At 3 months, the values were +11.8 ± 18.1 µm, +1.8 ± 17.5 µm (P = .055), and -1.3 ± 6.4 µm (P = .055), respectively. Pseudophakic cystoid macular edema (PCME) was reported in two eyes, both with prednisolone acetate monotherapy. After surgery, conjunctival injection lasted 6.5 ± 5.0 days and irritation of the eye 9.5 ± 8.5 days in prednisolone acetate group compared with nepafenac (2.6 ± 2.2 days; P = .037 and 4.3 ± 5.2 days; P = NS, respectively) and combination therapy (3.3 ± 1.9 days; P = NS and 3.0 ± 4.0 days; P = .025, respectively). CONCLUSIONS: Routine cataract surgery of PXF eyes with nonsteroidal anti-inflammatory drugs (NSAID) alone, or in combination with steroids resulted in faster recovery from surgery and avoidance of PCME compared to steroids alone. ABBREVIATIONS: BAB: blood-aqueous barrier; CDVA: corrected distance visual acuity; CDE: cumulative dissipated energy; CSMT: central subfield macular thickness; HRQoL: Health-related quality of life; IOP: intraocular pressure; logMAR: log of the minimum angle of resolution; NSAID: nonsteroidal anti-inflammatory drug; PCME: pseudophakic cystoid macular edema; PXF: pseudoexfoliation syndrome; OCT: optical coherence tomography; t.i.d.: three times a day; VA: visual acuity.

Prophylactic NS-21 maintains the skin moisture but does not reduce the severity of radiation dermatitis in patients with head and neck cancer: a randomized control trial.

BACKGROUND: To evaluate the practicality of NS-21 cream with regard to its skin-related toxicity in patients with head and neck cancer (HNC) who are undergoing concurrent chemoradiation therapy (CCRT) or radiotherapy (RT). METHODS: Between July 2015 and November 2017, 30 HNC patients who underwent RT or CCRT were randomly allocated to receive either NS-21 or control treatment on their irradiated skin three times per day, starting at the initiation of RT or CCRT and ending 2 weeks after the completion of RT or until the appearance of grade 3 acute radiation dermatitis (ARD). Dermatitis was recorded weekly according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Skin humidity was monitored by a digital moisture meter. The generalized estimating equation (GEE) and logit link function method were used for statistical analysis. RESULTS: No serious adverse events were observed in either group. Itching dermatitis occurred on the right lower neck in one patient of the NS-21 group during the 3rd week of CCRT, but the severity was mild. The median skin moisture value at the time of the final treatment was significantly different between the study and control groups (30.6 vs. 27.3, p = 0.013). Additionally, there was an inverse relationship between skin moisture and ARD grade (B = -0.04, p = 0.005). The incidence of ARD at the time of the last treatment was not significantly different between the study and control groups (6.7% vs 26.7%, p = 0.165). The risk of grade 3 ARD for skin that had received an irradiation dose of 47-70 Gy was higher than that of skin that had received an irradiation dose ≤46 Gy (OR = 31.06, 95% CI =5.95-162.21, p < 0.001). Nevertheless, the risk of ARD was not significantly different between the groups (OR = 0.38, 95% CI = 0.08-1.74, p = 0.212). CONCLUSIONS: NS-21 was well tolerated and effective for the maintenance of skin moisture; however, there was no statistically significant reduction in the risk of ARD in HNC patients undergoing RT or CCRT when compared with HNC patients in the control group. TRIAL REGISTRATION: The study was approved by the Institutional Review Board of Far Eastern Memorial Hospital ( FEMH-IRB , 104048-F), Registered 1st June 2015.

Synergistically dual-functional nano eye-drops for simultaneous anti-inflammatory and anti-oxidative treatment of dry eye disease.

We have developed a rapid and straightforward topical treatment method for dry eye disease (DED) using poly(catechin) capped-gold nanoparticles (Au@Poly-CH NPs) carrying amfenac [AF; a nonsteroidal anti-inflammatory drug (NSAID)] through effective attenuation of ocular surface tissue damage in dry eyes. A dual-targeted strategy based on ocular therapeutics was adopted to simultaneously block the cyclooxygenase enzymes-induced inflammation and reactive oxygen species (ROS)-induced oxidative stress, the primary two causes of DED. The self-assembled core-shell Au@Poly-CH NPs synthesized via a simple reaction between tetrachloroaurate(iii) and catechin possess a poly(catechin) shell (∼20 nm) on the surface of each Au NP (∼60 nm). The anti-oxidant and anti-inflammatory properties of AF/Au@Poly-CH NPs were evaluated by DCFH-DA and prostaglandin E2/VEGF assays, respectively. Our results demonstrate that Au@Poly-CH NPs not only act as an anti-oxidant to suppress ROS-mediated processes, but also serve as a drug carrier of AF for a synergistic effect on anti-inflammation. In vivo biocompatibility studies show good tolerability of AF/Au@Poly-CH NPs for potential use in the treatment of ocular surface pathologies. The dual-targeted therapeutic effects of AF/Au@Poly-CH NPs lead to rapid recovery from DED in a rabbit model. Au@Poly-CH NPs loaded with NSAIDs is a promising multifunctional nanocomposite for treating various inflammation- and oxidative stress-related diseases.

Meloxicam vs robenacoxib for postoperative pain management in dogs undergoing combined laparoscopic ovariectomy and laparoscopic-assisted gastropexy.

OBJECTIVE: To compare meloxicam and robenacoxib for short-term postoperative pain management after combined laparoscopic ovariectomy and laparoscopic-assisted gastropexy. STUDY DESIGN: Double-blind, prospective, randomised clinical trial. ANIMALS: Twenty-six client-owned female dogs. METHODS: Dogs undergoing combined laparoscopic ovariectomy and laparoscopic-assisted gastropexy were randomly divided into 2 groups. Before induction of anesthesia, 13 dogs received meloxicam (0.2 mg/kg subcutaneously), and 13 dogs received robenacoxib (2 mg/kg subcutaneously). Pain was scored with the Glasgow Composite Pain Scale (short form) before surgery and at 1, 6, 12, 18, and 24 hours after extubation. Rescue analgesia (tramadol, 3 mg/kg) was provided to dogs with a Glasgow pain score (GPS) ≥5. Glasgow pain scores were analyzed by ANOVA with treatment, age, and surgical time as fixed factors. RESULTS: Glasgow pain scores were higher at 24 hours postsurgery in dogs treated with robenacoxib (2.18 ± 0.29) compared with those treated with meloxicam (0.68 ± 0.41, P = .04). Two dogs treated with meloxicam and 7 dogs treated with robenacoxib required rescue analgesia. Regardless of the treatment, the overall GPS was lower at 18 and 24 hours postsurgery when the surgical time was >40 minutes compared with surgical times ≤40 minutes, but surgical site inflammation was likely a confounding factor in this finding. Glasgow pain score was not affected by patient age. CONCLUSION: Meloxicam was more effective than robenacoxib at controlling pain in the population of dogs reported here. CLINICAL SIGNIFICANCE: Preoperative administration of meloxicam effectively controls pain for 24 hours after combined laparoscopic ovariectomy and laparoscopic-assisted gastropexy, but rescue analgesia may be required.

The Challenges of Approaching and Managing Gout.

Despite many effective treatments for gout, its management remains a challenge internationally. Options for optimizing gout management may differ in different practice sizes and settings. Gout incidence is rising and it continues to be associated with increased mortality. Education of patients and medical providers is essential, and newer gout medications need to be used in the most appropriate ways for cost-effective therapy. Special consideration needs to be given to such populations as the elderly and those with renal and cardiovascular disease in gout management. New agents are in development, which may add to the armamentarium for gout management.

Efficacy of addition of nepafenac 0.1% to steroid eye drops in prevention of post-phaco macular edema in high-risk eyes.

PURPOSE: To compare the efficacy of addition of nonsteroidal anti-inflammatory eye drops to steroidal eye drops with that of using postoperative steroidal anti-inflammatory eye drops alone in prevention of macular edema in high-risk patients. SETTING: Cairo University Hospital. DESIGN: This study was comparative prospective interventional randomized study. METHODS: This study included 100 cataractous eyes divided into five subgroups: 20 eyes of diabetic patients, 20 uveitic eyes, 20 traumatic cataracts, 20 glaucomatous eyes on topical prostaglandin analogs, and 20 eyes with posterior capsular rupture during phacoemulsification. Each subgroup of 20 was randomized between two groups of 10 eyes, group A received postoperative topical steroids alone and group B received both steroidal and nonsteroidal anti-inflammatory eye drops. RESULTS: There was significant increase in postoperative central foveal thickness as compared to preoperative values in both groups (60.9 ± 87.95 µ in group A and 25.52 ± 57.26 µ in group B) that was significantly more in group A (P value 0.016). There was significant difference in postoperative macular thickness between both groups (280.1 ± 86.0 µ and 246.80 ± 57.73 µ, respectively, in groups A and B) (P value = 0.012). There was no statistically significant difference between both groups in preoperative and postoperative corrected distance visual acuity and intraocular pressure. CONCLUSION: Addition of topical nepafenac eye drops to topical steroid drops significantly reduced the amount of pseudophakic macular edema after cataract surgery in high-risk eyes.

[Visual disorder after visual contact with a geodetic laser]. / Visual disorder after visual contact with a geodetic laser.

Macular edema is a rare complication that can occur under the influence of light. Damage occurs as a result of focusing the light beam on the macula. A 23-year-old patient reported to the hospital due to a sudden reduction in visual acuity of the left eye after visual contact with a geodetic laser at work. After full diagnosis and treatment implementation after 3 weeks, vision improvement was achieved. The case report shows the harmful effects of laser techniques on human vision.

Arhalofenate acid inhibits monosodium urate crystal-induced inflammatory responses through activation of AMP-activated protein kinase (AMPK) signaling.

BACKGROUND: Arhalofenate acid, the active acid form of arhalofenate, is a non-agonist peroxisome proliferator-activated receptor γ (PPARγ) ligand, with uricosuric activity via URAT1 inhibition. Phase II studies revealed decreased acute arthritis flares in arhalofenate-treated gout compared with allopurinol alone. Hence, we investigated the anti-inflammatory effects and mechanisms of arhalofenate and its active acid form for responses to monosodium urate (MSU) crystals. METHODS: We assessed in-vivo responses to MSU crystals in murine subcutaneous air pouches and in-vitro responses in murine bone marrow-derived macrophages (BMDMs) by enzyme-linked immunosorbent assay (ELISA), SDS-PAGE/Western blot, immunostaining, and transmission electron microscopy analyses. RESULTS: Oral administration of arhalofenate (250 mg/kg) blunted total leukocyte ingress, neutrophil influx, and air pouch fluid interleukin (IL)-1ß, IL-6, and CXCL1 in response to MSU crystal injection (p < 0.05 for each). Arhalofenate acid (100 µM) attenuated MSU crystal-induced IL-1ß production in BMDMs via inhibition of NLRP3 inflammasome activation. In addition, arhalofenate acid dose-dependently increased activation (as assessed by phosphorylation) of AMP-activated protein kinase (AMPK). Studying AMPKα1 knockout mice, we elucidated that AMPK mediated the anti-inflammatory effects of arhalofenate acid. Moreover, arhalofenate acid attenuated the capacity of MSU crystals to suppress AMPK activity, regulated expression of multiple downstream AMPK targets that modulate mitochondrial function and oxidative stress, preserved intact mitochondrial cristae and volume density, and promoted anti-inflammatory autophagy flux in BMDMs. CONCLUSIONS: Arhalofenate acid is anti-inflammatory and acts via AMPK activation and its downstream signaling in macrophages. These effects likely contribute to a reduction of gout flares.

Nepafenac Ophthalmic Suspension 0.3% for the Management of Ocular Pain After Photorefractive Keratectomy.

PURPOSE: To investigate the effect of nepafenac 0.3% in a once daily dosage regarding pain and healing after photorefractive keratectomy (PRK). METHODS: This was a prospective, comparative, contralateral randomized study of 35 patients undergoing PRK for the correction of low to moderate myopia and myopic astigmatism. After randomization, patients received nepafenac 0.3% ophthalmic suspension once daily in one eye (nepafenac 0.3% group) and nepafenac 0.1% ophthalmic suspension three times a day in the other eye (nepafenac 0.1% group) until the second postoperative day. Pain was evaluated every 2 hours on the day of the operation and then once daily using a scale ranging from 0 to 4. Patients were then examined at 2 weeks and 1, 3, 6, and 12 postoperative months. Visual acuity and subepithelial haze were also assessed. RESULTS: No differences were detected between groups in pain scores, subepithelial haze scores, or visual acuity. Refractive predictability was also similar. CONCLUSIONS: Nepafenac 0.3% ophthalmic suspension in a daily regimen after PRK seems to be an effective treatment for pain and ocular discomfort with effects similar to the 0.1% suspension.

Delivery systems for agriculture: Fe-EDDHSA/CaCO3 hybrid crystals as adjuvants for prevention of iron chlorosis.

Fe-EDDHSA/CaCO3 hybrid crystals are synthesized and tested in vitro to determine their effect in treating iron chlorosis in kiwifruit plants, used as a proof of concept. Under the alkaline conditions provided by the calcareous substrate, plants release protons that dissolve the hybrids and trigger Fe uptake. These CaCO3 hybrids represent a new system for active molecule delivery in agriculture.

Intracameral Use of Nepafenac: Safety and Efficacy Study.

PURPOSE: To test the intracameral safety of nepafenac and its efficacy in inhibiting prostaglandin synthesis during phacoemulsification surgery. METHODS: The safety evaluation was conducted in normal eyes of rabbits, 0.1ml of 0.3% and 1% nepafenac was injected intracamerally. Extensive studies to detect adverse response ranged from a gross examination of eyes under slit lamp biomicroscope, fluorescein dye test, Schirmer tear test, test for corneal sensitivity, intraocular pressure measurement (IOP), specular microscopy, electroretinography(ERG), and histopathological examination of intraocular tissues. Efficacy of nepafenac was studied by intracameral injection of 0.1%, 0.3% nepafenac, nepafenac 0.3%+1% lignocaine, and 1% lignocaine alone, before phacoemulsification surgery and intraoperative mydriasis along with PGE2(ProstaglandinE2) secretion were recorded. RESULTS: Single 0.1ml of 0.3% or 1% nepafenac did not significantly (p > 0.05) alter physiological parameters and histology of cornea, iris, and retina. Nepafenac 0.3% effectively inhibited PGE2 secretion. No significant (p > 0.05) prevention of miosis was recorded with 0.1% or 0.3% nepafenac. However, a combination of 0.3% nepafenac + 1% lignocaine and 1% lignocaine alone significantly (p < 0.05) arrested miosis during the intraoperative period. CONCLUSION: An intracameral concentration of up to 1% nepafenac does not adversely affect the rabbit eye. Nepafenac fails to prevent miosis but inhibits prostaglandin release during phacoemulsification surgery.

Managing Gout Flares in the Elderly: Practical Considerations.

Gout is common in the elderly, affecting an estimated 4.7 million people aged > 60 years in the USA alone. The incidence and prevalence of gout increases, and male predisposition to gout reduces, with increasing age. The elderly have more comorbidities, and gout manifests differently, with more frequent involvement of knees, ankles, and wrists at disease onset, systemic upset, and tophi. Comorbidities and polypharmacy make the management of gout flares challenging in this population. Intra-articular corticosteroid injection remains the treatment of choice for accessible joints, oral prednisolone is preferred over low-dose colchicine, and non-steroidal anti-inflammatory drugs (NSAIDs) are best avoided. Xanthine oxidase inhibitors (XOI) remain the first-line treatment for hyperuricemia in the elderly. Arhalofenate, an emerging uricosuric anti-inflammatory drug, prevents gout flares while reducing serum urate. It may be particularly relevant in the treatment of gout in the elderly as they are unable to tolerate long-term colchicine for flare prophylaxis and frequently have contraindications to corticosteroids and NSAIDs. However, given its modest urate-lowering effect, it can only be used in combination with an XOI, and the safety and efficacy of this drug has not been examined in the elderly or in those with chronic kidney disease. Diuretics and beta-blockers should be discontinued where feasible, whereas low-dose aspirin can be continued if otherwise indicated.
