Febuxostat exhibits unprecedented solid forms with a total of 40 polymorphs and pseudopolymorphs reported. Polymorphs differ in molecular arrangement and conformation, intermolecular interactions, and various physicochemical properties, including mechanical properties. Febuxostat Form Q (FXT Q) and Form H1 (FXT H1) were investigated for crystal structure, nanomechanical parameters, and bulk deformation behavior. FXT Q showed greater compressibility, densification, and plastic deformation as compared to FXT H1 at a given compaction pressure...

Gout is the most prevalent inflammatory arthritis and affects 2.5% of the general population in the UK. It is also the only arthritis that has the potential to be cured with safe, inexpensive and well tolerated urate-lowering treatments, which reduce serum uric acid by either inhibiting xanthine oxidase - eg allopurinol, febuxostat - or by increasing the renal excretion of uric acid. Of these, xanthine oxidase inhibitors are used first line and are effective in 'curing' gout in the vast majority of patients...

REVIEW
Marwan H Adwan
PURPOSE OF THE REVIEW: The purpose of the review is to summarise the various drugs used in rheumatology practice implicated in the causation of DRESS syndrome. RECENT FINDINGS: The most commonly reported drugs are allopurinol, sulfasalazine and minocycline, which pose a very high risk for DRESS syndrome development, followed by strontium ranelate and dapsone. Other, less commonly reported, drugs include leflunomide, hydroxychloroquine, non-steroidal anti-inflammatory drugs, febuxostat, bosentan and solcitinib...

The new chemical entities febuxostat and topiroxostat have been approved by the US Food and Drug Administration, opening new avenues for exploiting different heterocycles other than purines as xanthine oxidase (XO) inhibitors. A different series of substituted 2-benzamido-4-methylthiazole-5-carboxylic acid derivatives (5a-r) was synthesized and characterized by the collective use of IR, (1) H and (13) C NMR, and mass spectroscopy, for the treatment of gout and hyperuricemia. In vitro studies of the synthesized derivatives revealed that the presence of a fluoro group at the para position in 5b (IC50  = 0...

The pharmacokinetics (PKs) of febuxostat varies among individuals, while the main causes are still unknown. We investigated whether the polymorphisms of UGT1A1 and UGT1A3 played an important role in the disposition of the drug after oral administration of febuxostat tablet in Chinese subjects. A total of 42 healthy subjects were from two previous independent clinical bioequivalence (BE) trials of febuxostat, in which the same reference formulation (ULORIC(®) tablet, 80 mg) was taken, and thus the PK data were combined for the evaluation of pharmacogenomic effect on febuxostat PKs...

BACKGROUND: Hyperuricemia is a common adverse event frequently found in renal transplant recipients with mizoribine (MZ). Hyperuricemia itself will be a cause of renal dysfunction, and renal dysfunction also will be a cause of hyperuricemia simultaneously. This study investigates frequency of hyperuricemia and renal failure in renal transplant recipients treated with high-dose MZ. PATIENTS AND METHODS: From December 2007 to October 2015, there was a total of 32 living related renal transplant recipients treated with high-dose MZ...

INTRODUCTION: Febuxostat, a nonpurine xanthine oxidase inhibitor, is approved as the first-line urate-lowering therapy in gout patients with normal renal function or mild to moderate renal impairment. The most common adverse effects of febuxostat are liver function test abnormalities, diarrhea, and skin rash. However, there is insufficient data in patients with severe renal impairment and end-stage renal disease (ESRD). We report the first case, to our knowledge, in which agranulocytosis developed after febuxostat treatment in an ESRD patient...

Lesinurad is a novel selective uric acid reabsorption inhibitor approved for treatment of hyperuricemia associated with gout in combination with xanthine oxidase inhibitors (XOIs). Open-label pharmacokinetic studies were performed in volunteers or subjects with hyperuricemia (serum uric acid ≥ 8 mg/dL) to investigate interactions of lesinurad (with and without concurrent XOIs) with colchicine and 2 nonsteroidal anti-inflammatory drugs: naproxen and indomethacin. Colchicine studies included consecutive 7-day treatment periods of (1) allopurinol 300 mg, allopurinol 300 mg plus lesinurad 400 or 600 mg, and continued lesinurad 400 or 600 mg; or (2) febuxostat 40 or 80 mg, febuxostat 40 or 80 mg plus lesinurad 400 mg, and continued febuxostat 40 or 80 mg plus lesinurad 600 mg...

OBJECTIVE: Arhalofenate (ARH), in development for gout, has uricosuric and anti-flare activities. ARH plus febuxostat (FBX) were evaluated in subjects with gout for serum uric acid (SUA) lowering, drug interaction, and safety. METHODS: Open phase II trial in gout volunteers (NCT02252835). Cohort 1 received ARH 600 mg for 2 weeks, followed by sequential 1-week co-administration of FBX 80 mg followed by 40 mg. FBX 40 mg was continued alone for 2 weeks. Cohort 2 received ARH 800 mg for 2 weeks, followed by sequential 1-week co-administration of FBX 40 mg followed by 80 mg...

Febuxostat is an orally administered selective inhibitor of xanthine oxidase approved for the treatment of gout and prevention of tumor lysis syndrome. It is a relatively safe medication. Hypersensitivity reactions associated with the use of febuxostat are quite rare with only one reported case of DRESS syndrome. Recently, two case reports of rhabdomyolysis following the initiation of febuxostat were published. We hereby present the first case of rhabdomyolysis with hypereosinophilia following the administration of febuxostat to a 50-year-old patient newly diagnosed with marginal zone lymphoma...

OBJECTIVE: To evaluate and compare the safety and efficacy of three urate lowering agents: febuxostat, allopurinol, and benzbromarone, when used to treat Chinese gout patients. METHODS: A total of 120 patients treated in our department from November 2011 to December 2014 were randomly selected and divided into four groups: febuxostat (40 mg per day), febuxostat (80 mg per day), allopurinol (100 mg, 3 × per day) or benzbromarone (50 mg per day), (n = 30 patients/group)...

OBJECTIVE: Positive HLA-B*5801 carriers are at greater risk of experiencing rare but severe allopurinol hypersensitivity syndrome (AHS) [i.e., Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)]; however, HLA-B*5801 prevalence and AHS risk vary by race/ethnicity. We evaluated the cost-effectiveness of HLA-B*5801 testing according to race/ethnicity in the United States. METHODS: We determined the cost-effectiveness of universal testing for HLA-B*5801 compared to no testing prior to the initiation of allopurinol per US major race/ethnicity groups...

We aimed to investigate the effects of febuxostat on IR and the expression of high-sensitivity C-reactive protein (hs-CRP) in patients with primary gout. Forty-two cases of primary gout patients without uric acid-lowering therapy were included in this study. After a physical examination, 20 age- and sex-matched patients were included as normal controls. The levels of fasting insulin (INS), fasting blood glucose (FBG), and hs-CRP were determined. IR was assessed using the Homeostasis Model Assessment of Insulin Resistance (HOMA-IR)...

BACKGROUND: Paroxysmal atrial fibrillation (PAF) can increase thrombogenesis risk, especially in the left atrium (LA). The exact mechanism is still unclear. OBJECTIVE: We assessed the effects of PAF on endothelial function, and investigated if febuxostat (FX) can attenuate endothelial dysfunction by inhibition of xanthine oxidase (XO). MATERIALS AND METHODS: Eighteen male New Zealand white rabbits were divided randomly into sham-operated (S), PAF (P) or FX+pacing (FP) groups...

Objective The effects of febuxostat therapy on hyperuricemia in patients with and without type 2 diabetes were compared in this retrospective observational study after pair-matching using the propensity scores. Methods In total, 160 patients with hyperuricemia were studied as the treated set, and the 155 subjects in whom the administration of febuxostat was not discontinued during the observation period were investigated in the full analysis. The study subjects were divided into two groups based on the style of initiation of febuxostat: initial and switching therapy from allopurinol administration...
