Paracetamol (Acetaminophen) in stroke 2 (PAIS 2): protocol for a randomized, placebo-controlled, double-blind clinical trial to assess the effect of high-dose paracetamol on functional outcome in patients with acute stroke and a body temperature of 36.5 °C or above. [2015]
RATIONALE: In the first hours after stroke onset, subfebrile temperatures and fever have been associated with poor functional outcome. In the first Paracetamol (Acetaminophen) in Stroke trial, a randomized clinical trial of 1400 patients with acute stroke, patients who were treated with high-dose paracetamol showed more improvement on the modified Rankin Scale at three-months than patients treated with placebo, but this difference was not statistically significant...

Clinical Trials Related to Tylenol (Acetaminophen)

Equality Study of Ofirmev vs Oral Acetaminophen [Not yet recruiting]
Acetaminophen (Tylenol) is a drug that is used commonly for relief of mild to moderate pain. It is found in many pain medicines that people take after having surgery. Narcotics are other drugs also used for pain (examples of narcotics are morphine and related pain medications). Medical science knows for a fact that acetaminophen works well when taken with narcotics for moderate to severe pain. Recently, acetaminophen has become available in an intravenous (IV) form called Ofirmev®. The IV form means that acetaminophen can be given into a vein. The benefits of getting medicine from an IV include:

- making the medicine work quickly

- less medicine having to pass through the liver to be changed into a form that your body

can process The investigators know that acetaminophen is helpful for pain relief at the time of surgery and after surgery. Acetaminophen is a very popular drug in outpatient surgery for pain control when patients go home. The patient's surgeon uses it to control pain after surgery at home in the form of Lortab or Percocet (Lortab and Percocet also have a narcotic medicine that mixes with acetaminophen). Also, currently at Surgicare, some anesthesiologists give intravenous acetaminophen while the patient is waiting to go to surgery. The investigators currently do not give any patient acetaminophen by mouth BEFORE surgery. However, since the addition of the IV form to the drug market, there has been interest to see if the oral form is just as good or better in reducing pain after surgery. This is why we are asking patients to join our study. The goal of this study is to find out if the oral form (by mouth) or the IV form (given into a vein) of acetaminophen controls pain after surgery better.

Protective Effects of Propylene Glycol in Daily Acetaminophen Dosing [Recruiting]
A purpose of this protocol is to is to compare the metabolites of the toxic bioactivating pathway after acetaminophen alone or acetaminophen followed by Propylene Glycol (PG) and to determine if it prevents the formation of the toxic metabolites of acetaminophen.

Effect on Acetaminophen Metabolism by Liquid Formulations [Completed]
The purpose of this study is to determine whether excipients in the liquid formulation of acetaminophen prevent the formation of the toxic metabolites of acetaminophen.

A Randomized Crossover Study to Determine the Pharmacokinetics of Intranasally Administered Acetaminophen in Healthy Adults [Withdrawn]
This study is being done to determine the systemic absorption of nasally inhaled acetaminophen (Tylenol®) versus orally ingested acetaminophen by comparing the serum drug concentrations of the two groups obtained at various times after study drug administration.

Analgesic Effect of Paracetamol, Paracetamol + Codeine, Ibuprofen and Their Combination [Recruiting]
The purpose of this study is to determine whether the combination of paracetamol (acetaminophen) and other NSAIDs with or without weak opioids can give synergistic analgesic effect.
