Meta AnalysisA Systematic Review of the Evidence Behind Use of Reduced Doses of Acetaminophen in Chronic Liver Disease.
Acetaminophen is among the most commonly used nonopioid analgesics, but significant variation exists in its prescribing practices for cirrhosis patients. Our primary objective was to describe the quality of evidence supporting or refuting the use of acetaminophen in patients with hepatic dysfunction. A comprehensive literature review of PubMed, Cochrane Library, Web of Science, and International Pharmaceutical Abstracts using the search terms "acetaminophen," "paracetamol," "chronic liver disease," "cirrhosis," and "hepatic disease" for studies describing changes in acetaminophen metabolism in patients with hepatic dysfunction was conducted. ⋯ The level of certainty for dosing recommendations obtainable from reviewing the evidence is low due to a small number of studies meeting search criteria, small samples sizes, inadequate information regarding cirrhosis etiology and compensated versus uncompensated liver disease, and lack of information on patient centered health outcomes. High-quality trials are not available to support the use of decreased acetaminophen doses in compensated cirrhosis patients. Acetaminophen can be a safe analgesic in patients with compensated hepatic dysfunction after careful analysis of patient-specific factors.

Randomized Controlled Trial
Pharmacokinetics and Abuse Potential of Benzhydrocodone, a Novel Prodrug of Hydrocodone, After Intranasal Administration in Recreational Drug Users.
Developing an acetaminophen-free, immediate-release hydrocodone product remains an unmet medical need; however, new opioid analgesics should not introduce new abuse risks. Benzhydrocodone is a prodrug of hydrocodone that must be metabolized into hydrocodone by enzymes in the intestinal tract to optimally deliver its pharmacologic effects. This study evaluated the intranasal pharmacokinetics and abuse potential of benzhydrocodone active pharmaceutical ingredient (API) compared with hydrocodone bitartrate (HB) API. ⋯ Reductions in hydrocodone exposure and associated decreases in Drug Liking relative to HB suggest that the prodrug benzhydrocodone may deter intranasal abuse.

Review Case Reports
Refractory Hypotension Caused by Prazosin Overdose Combined With Acetaminophen and Naproxen Toxicity: A Case Report and Review of the Literature.
Pediatric exposure to prazosin is unusual because it is most commonly indicated for the treatment of hypertension. Prazosin's increase in popularity as a treatment for posttraumatic stress disorder makes it important for emergency physicians to be aware of how to manage potential toxic ingestion because of prazosin overdose. ⋯ A 16-year-old, 76-kg female presented after ingesting 110 mg of prazosin, 209.3 g of acetaminophen, and 55 g of naproxen. She was admitted to the pediatric intensive care unit for rapidly deteriorating hypotension (lowest blood pressure 47/19 mm Hg) refractory to aggressive fluid resuscitation and infusions of epinephrine and norepinephrine each at 0.5 mcg/kg/min. Stabilization of blood pressure was eventually achieved, and associated with use of a vasopressin infusion of 0.004 units/kg/min. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Because of the increasing exposure of children to prazosin, clinicians should be aware of the pharmacology behind alpha-1 antagonist overdose and consider treatment options, such as vasopressin, when hypotension is resistant to standard fluid and catecholamine therapy.

Randomized Controlled TrialEfficacy and safety of fixed-dose combination of drotaverine hydrochloride (80 mg) and paracetamol (500 mg) in amelioration of abdominal pain in acute infectious gastroenteritis: A randomized controlled trial.
This randomized controlled trial was undertaken to assess efficacy and safety of fixed-dose combination of drotaverine hydrochloride (80 mg) and paracetamol (PCM) (500 mg). This was performed by comparison of mean pain intensity difference, total pain relief at 2 h, onset of pain relief, decrease in number of pain episodes, global improvement, and adverse effects. ⋯ Fixed-dose combination of drotaverine hydrochloride (80 mg) and PCM (500 mg) is an effective and safe antispasmodic agent in abdominal pain associated with acute infectious gastroenteritis.
