Acetaminophen and codeine is supplied in tablet form for oral administration.
Acetaminophen, 4'-hydroxyacetanilide, a slightly bitter, white, odorless, crystalline powder, is a non-opiate, non-salicylate analgesic and antipyretic.
Codeine phosphate, 7,8-didehydro-4,5α-epoxy-3-methoxy-17methylmorphinan-6α-ol phosphate (1:1) (salt) hemihydrate, a white crystalline powder, is a narcotic analgesic and antitussive.
Acetaminophen and codeine phosphate tablets are indicated for the relief of mild to moderately severe pain.

Clinical Trials Related to Acetaminophen with Codeine (Codeine / 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.
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.
Acetaminophen for Cancer Pain [Recruiting]
Many patients with cancer pain have pain not fully controlled on opioids (eg. morphine).
The addition of acetaminophen (Tylenol) to opioids in a small study in cancer patients
demonstrated better pain control without an increase in side effects. This study will
determine if regular acetaminophen improves pain control when added to strong opioids in
patients with cancer pain.
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.
A Randomized Crossover Study to Determine the Pharmacokinetics of Intranasally Administered Acetaminophen in Healthy Adults [Withdrawn]
