Anturen - General Information
A uricosuric drug that is used to reduce the serum urate levels in gout therapy. It lacks anti-inflammatory, analgesic, and diuretic properties.
Pharmacology of Anturen
Anturen's pharmacologic activity is the potentiation of the urinary excretion of uric acid. It is useful for reducing the blood urate levels in patients with chronic tophaceous gout and acute intermittent gout, and for promoting the resorption of tophi.
Anturen for patients
No information provided.
Patients with an active peptic ulcer or symptoms of gastrointestinal inflammation or ulceration should not receive the drug.
The drug is contraindicated in patients with a history or the presence of:
1. Hypersensitivity to phenylbutazone or other pyrazoles
2. Blood dyacrasias
Additional information about Anturen
Anturen Indication: For the treatment of gout and gouty arthritis.
Mechanism Of Action: Anturen is an oral uricosuric agent (pyrazolone derivative) used to treat chronic or intermittent gouty arthritis. Anturen competitively inhibits the reabsorption of uric acid at the proximal convoluted tubule, thereby facilitating urinary excretion of uric acid and decreasing plasma urate concentrations. This is likely done through inhibition of the urate anion transporter (hURAT1) as well as the human organic anion transporter 4 (hOAT4). Anturen is not intended for the treatment of acute attacks because it lacks therapeutically useful analgesic and anti-inflammatory effects. Anturen and its sulfide metabolite possess COX inhibitory effects. Anturen has also been shown to be a UDP-glucuronsyltransferase inhibitor and a very potent CYP2C9 inhibitor. Anturen is also known to be a cystic fibrosis transmembrane conductance regulator (CFTR) inhibitor as well as an inhibitor of several multridrug resistance proteins (MRPs).
