Eburic Tablet 40 mg
Eburic Tablet 40 mg Uses, Dosage, Side Effects, Food Interaction and all others data.
Eburic Tablet 40 mg is a non-purine, selective xanthine oxidase (XO) inhibitor. It decreases serum uric acid level by inhibiting xanthine oxidase, which is responsible for uric acid production. Xanthine oxidase breaks down hypoxanthine to xanthine and thus to uric acid. Eburic Tablet 40 mg is not expected to inhibit other enzymes involved in purine and pyrimidine synthesis and metabolism at therapeutic concentrations.
Eburic Tablet 40 mg is a novel, selective xanthine oxidase/dehydrogenase inhibitor that works by decreasing serum uric acid in a dose-dependent manner. In healthy subjects, febuxostat decreased the mean serum uric acid and serum xanthine concentrations, as well as the total urinary uric acid excretion. Eburic Tablet 40 mg at daily doses of 40-80 mg reduced the 24-hour mean serum uric acid concentrations by 40 to 55%. Closely related to the drug-induced reduction of serum uric acid levels and mobilization of urate crystals in tissue deposits, febuxostat is associated with gout flares.
Unlike allopurinol and oxypurinol, febuxostat has no inhibitory actions against other enzymes involved in purine and pyrimidine synthesis and metabolism, because it does not structurally resemble purines or pyrimidines.

Uses
Eburic Tablet 40 mg is used for the long-term management of Hyperuricemia in patients with gout. It is not recommended for use in the treatment of asymptomatic Hyperuricemia.
Eburic Tablet 40 mg is also used to associated treatment for these conditions: Chronic, symptomatic Hyperuricemia
How Eburic Tablet 40 mg works
Gout is a form of acute arthritis that is characterized by the accumulation of crystals of monosodium urate and urate crystals in or around a joint, leading to inflammation and persistent urate crystal deposition in bones, joints, tissues, and other organs that may exacerbate over time. Hyperuricemia is closely related to gout, whereby it may exist for many years before the first clinical attack of gout; thus, aberrated serum uric acid levels and hyperuricemia are believed to be the biochemical aberration involved in the pathogenesis of gout. Xanthine oxidoreductase (XOR) can act as a xanthine oxidase or xanthine dehydrogenase. In humans, it is a critical enzyme for uric acid production as it catalyzes the oxidation reaction steps from hypoxanthine to xanthine and from xanthine to uric acid in the pathway of purine metabolism. Eburic Tablet 40 mg potently inhibits XOR, blocking both its oxidase and dehydrogenase activities. With high affinity, febuxostat binds to XOR in a molecular channel leading to the molybdenum-pterin active site, where allopurinol demonstrates relatively weak competitive inhibition.
XOR is mainly found in the dehydrogenase form under normal physiological conditions; however, in inflammatory conditions, XOR can be converted into the xanthine oxidase form, which catalyzes reactions that produce reactive oxygen species (ROS), such as peroxynitrite. ROS contribute to vascular inflammation and alterations in vascular function. As febuxostat can inhibit both forms of XOR, it can inhibit ROS formation, oxidative stress, and inflammation. In a rat model, febuxostat suppressed renal ischemia-reperfusion injury by attenuating oxidative stress.
Dosage
Eburic Tablet 40 mg dosage
The recommended starting dosage of Eburic Tablet 40 mg is 40 mg once daily. For patients who do not achieve a serum uric acid concentration of less than 6 mg/dL after 2 weeks at the 40 mg dose, Eburic Tablet 40 mg 80 mg once daily is recommended. Eburic Tablet 40 mg can be administered without regard to food or antacid use.
Side Effects
The most common adverse events associated with the use of Eburic Tablet 40 mg may include liver function abnormalities, nausea, arthralgia, and rash.
Toxicity
Oral lowest published toxic dose (TDLO) in humans is 1.82 mg/kg/14D (intermittent). Oral LD50 is 300 mg/kg in mice, 3200 mg/kg in rabbits, and 980 mg/kg in rats.
No dose-limiting toxicities were observed with febuxostat administered at doses up to 300 mg daily for seven days in healthy subjects. There are no reports of overdose of febuxostat in clinical studies and there is no known antidote. Overdose should be managed by symptomatic and supportive care.
Precaution
Gout Flare: An increase in gout flares is frequently observed during initiation of anti-hyperuricemic agents, including Eburic Tablet 40 mg. If a gout flare occurs during treatment, Eburic Tablet 40 mg need not be discontinued. Prophylactic therapy (i.e., non-steroidal anti-inflammatory drug (NSAID) or colchicine upon initiation of treatment) may be beneficial for up to six months.
Cardiovascular Events: A higher rate of cardiovascular thromboembolic events was observed in patients treated with febuxostat than allopurinol in clinical trials. Monitor for signs and symptoms of MI and stroke.
Liver Enzyme Elevation: Transaminase elevations have been observed in febuxostat -treated patients. Monitor liver function tests periodically.
Interaction
Concomitant administration of Eburic Tablet 40 mg with azathioprine, mercaptopurine or theophylline could increase plasma concentrations of these drugs resulting in severe toxicity.
Food Interaction
- Take with or without food. A high fat meal decreases Cmax and AUC in a clinically insignificant way.

Volume of Distribution
The apparent steady-state volume of distribution (Vss/F) of febuxostat ranges from 29 to 75 L, indicating a low to medium volume of distribution.
Elimination Route
After oral administration, about 85% of febuxostat is absorbed rapidly. Tmax ranges from 1 to 1.5 hours. Following once-daily oral administration, Cmax was approximately 1.6 ± 0.6 mcg/mL at a dose of 40 mg febuxostat and 2.6 ± 1.7 mcg/mL at a dose of 80 mg febuxostat.
A high-fat meal decreased Cmax by 49% and AUC by 18%, but there were no clinically significant changes in the ability of febuxostat to decrease serum uric acid concentrations.
Half Life
The apparent mean terminal elimination half-life of approximately 5 to 8 hours.
Clearance
Following oral administration of single doses of 10 to 240 mg, the mean apparent total clearance ranged from 10 to 12 L/h.
Elimination Route
Eburic Tablet 40 mg is eliminated via both hepatic and renal pathways. Following oral administration of 80 mg radiolabeled febuxostat, approximately 49% of the dose was recovered in the urine. In urine, about 3% of the recovered dose accounted for unchanged febuxostat, 30% accounted for the acyl glucuronide metabolite, 13% accounted for oxidative metabolites and their conjugates, and 3% accounted for unidentified metabolites.
Approximately 45% of the total dose was recovered in the feces, where 12% of the dose accounted for the unchanged parent drug. About 1% accounted for the acyl glucuronide metabolite, 25% accounted for oxidative metabolites and their conjugates, and 7% accounted for unidentified metabolites.
