Probenecid is a uricosuric drug, primarily used in treating gout or hyperuricemia, that increases uric acid removal in the urine. CAS registry numbers are unique numerical identifiers for chemical compounds, polymers, biological sequences and alloys. ... The Anatomical Therapeutic Chemical Classification System is used for the classification of drugs. ... A chemical formula (also called molecular formula) is a concise way of expressing information about the atoms that constitute a particular chemical compound. ...

The molecular mass of a substance (less accurately called molecular weight and abbreviated as MW) is the mass of one molecule of that substance, relative to the unified atomic mass unit u (equal to 1/12 the mass of one atom of carbon-12). ... Gout suppressants that act directly on the renal tubule to increase the excretion of uric acid, thus reducing its concentrations in plasma. ... Hyperuricemia is the presence of high levels of uric acid in the blood. ...


Probenecid also decreases the renal excretion of some drugs.


In one study, probenecid was shown to more than double a patient's exposure to oseltamivir (trade name Tamiflu), an antiviral drug used to combat influenza. This is significant because nations are currently stockpiling oseltamivir in anticipation of an influenza pandemic, and the drug is in short supply. During World War II, probenecid was used to extend limited supplies of penicillin, and is still currently used to increase antibiotic concentrations in serious infections. It has also found use as a masking agent by athletes attempting to get away with using performance enhancing drugs. Oseltamivir (INN) (IPA: ) is an antiviral drug used in the treatment and prophylaxis of both Influenzavirus A and Influenzavirus B. Like zanamivir, oseltamivir is a neuraminidase inhibitor. ... An influenza pandemic is a large scale epidemic of the influenza virus, such as the 1918 Spanish flu. ... Penicillin nucleus Penicillin refers to a group of β-lactam antibiotics used in the treatment of bacterial infections caused by susceptible, usually Gram-positive, organisms. ...


In the kidneys it is filtered at the glomerulus, secreted in the proximal tubule and reabsorbed in the distal tubule.


Probenecid's exact mechanism of action in the kidneys' nephrons is unknown. Human kidneys viewed from behind with spine removed The kidneys are bean-shaped excretory organs in vertebrates. ... Nephron of the kidney A nephron is the basic structural and functional unit of the kidney. ...

In patients on probenecid and colchicine the use of salicylates in either small or large doses is contraindicated because it antagonizes the uricosuric action of probenecid.
Probenecid and colchicine has been used in patients with some renal impairment but dosage requirements may be increased.
Probenecid and colchicine may not be effective in chronic renal insufficiency particularly when the glomerular filtration rate is 30 mL/minute or less.
