Acetaminophen toxicity is a result of the formation of a reactive intermediate N-acetyl-p-benzoquinonimine (NAPQI), the product of a minor pathway involved in the metabolism of acetaminophen. At therapeutic doses, the majority of acetaminophen metabolism occurs via glucuronidation and sulfation to nontoxic metabolites. In overdose, the nontoxic routes of metabolism become saturated and the metabolism of acetaminophen to NAPQI becomes a major metabolic pathway. The formation of NAPQI occurs primarily via oxidation by hepatic CYP2E1 and, to a lesser extent, by CYP3A4, CYP2A6, and CYP1A2. A fraction of the total NAPQI may be a result of renal CYP2E1 metabolism.

Less than 50% of the U.S. population obtains the seasonal influenza vaccine, and the vaccine does not confer perfect immunity. There are three types of influenza, plus numerous variations. Practitioners should be confident in the use of antiviral agents in patients with influenza. The most recent guidelines recommend the use of nonpharmacologic management and neuraminidase inhibitors to either prevent the transmission of influenza or treat the infection. Pharmacotherapy is based on an understanding of which
