Acetaminophen overdose

In 2006, about 2.5 million poison exposures were reported (8 per 1,000) in US with one poison exposure every 14 seconds (AAPCC Annual Report). Over 75% of reported poison exposures involve ingestion of a poisonous substance. Medical expenses related to poisoning amounts to $26 million every year. The most common cause of poisoning deaths in the US is attributed to acetaminophen (Tylenol®), a widely used pain reliever and fever reducer available in hundreds of over-the-counter and prescriptions drugs, with more than 1 billion tablets sold annually. Although it is safe at recommended doses, acetaminophen overdose is one of the top ten most fatal toxin exposures that caused over 127,000 exposures in 2003, 16,500 of which resulted in care in a medical facility. In adults, dosages exceeding 10 - 15 grams can result in liver failure and dosages exceeding 25 grams can be deadly. Acetaminophen overdose is a major cause of acute liver failure; the proportion of acetaminophen-induced acute liver failure cases has alarmingly increased from 21% in 1998 to 51% in 2003.

Sample preparation and analysis

10 mg of carbon was mixed with 20, 50 and 100 mg/l aqueous solution of acetaminophen. The mixtures were vortexed for 10 seconds and then allowed to sit idle for 5 minutes. The mixtures were then centrifuged for 5 minutes. 200 µL supernatant containing unabsorbed acetaminophen was withdrawn and put into an High Performance Liquid Chromatography (HPLC) vial for acetaminophen quantification. Acetaminophen concentrations after exposure to adsorbents were determined using an acetaminophen standard curve.

Results and discussion

Adsorption of acetaminophen by activated carbon sold by our competitor decreases with increase in acetaminophen concentration. Unlike activated carbon of our competitor, EnterosorbU has 100% adsorption even at higher acetaminophen concentration. EnterosorbU is a more efficient adsorbent than our competitor's product.

While companies using porous carbon can choose from hundreds of off-the-shelf commodity products, Carbon-Ukraine offers a new option: carbons whose properties are rapidly tuned for a specific application. We are interested in partnering with end-users to develop carbons specifically tailored to meet their needs. Normally, when developing materials for a new application we will begin by thoroughly studying the underlying technology and the key materials properties required. Once we have an understanding of the materials properties required, we can provide small quantities of material for evaluation. Based on the results of your evaluation, we can provide additional samples to further optimize our materials for your application.
