and Codeine Phosphate
Acetaminophen and codeine is supplied in tablet form for oral administration.
Acetaminophen, 4'-hydroxyacetanalide, 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-17-methylmorphinan-6α-ol phosphate (1:1) (salt) hemihydrate, a white crystalline powder, is a narcotic analgesic and antitussive.
Each tablet contains:

Published Studies Related to Codrix (Acetaminophen / Codeine)
Analgesic efficacy of rofecoxib compared with codeine/acetaminophen using a model of acute dental pain. [2005.10]
OBJECTIVE: To determine analgesic efficacy of a single oral dose of rofecoxib 50 mg compared with acetaminophen/codeine 600/60 mg, we conducted a double-blind, randomized, placebo- and active-comparator-controlled, parallel-group study... CONCLUSION: Rofecoxib provided superior analgesic efficacy compared with codeine/acetaminophen with fewer gastrointestinal and nervous system adverse events.
A randomized, double-blind, parallel-group study comparing the analgesic effect of etoricoxib to placebo, naproxen sodium, and acetaminophen with codeine using the dental impaction pain model. [2004.05]
OBJECTIVE: To compare the overall analgesic effect, including time to onset, peak and duration of effect for etoricoxib 120 mg, a new COX-2 selective inhibitor, in patients with acute pain to that of placebo. Naproxen sodium 550 mg and acetaminophen/codeine 600/60 mg were the active comparators.Etoricoxib was generally well tolerated.
Tramadol suppositories are less suitable for post-operative pain relief than rectal acetaminophen/codeine. [1999.07]
The suitability of tramadol suppositories for inclusion in our hospital formulary for the treatment of mild to moderate post-operative pain was evaluated. In an open randomized trial, rectal tramadol was compared with our standard treatment acetaminophen/codeine suppositories...
The analgesic efficacy of flurbiprofen compared to acetaminophen with codeine. 
In a single-dose, parallel group, randomized block treatment allocation study, the relative analgesic efficacy of flurbiprofen, a nonsteroidal antiinflammatory drug, was compared to acetaminophen 650 mg with codeine 60 mg, zomepirac sodium 100 mg, and placebo... The results of this study support previous work on flurbiprofen.
Comparison of ibuprofen and acetaminophen with codeine following cosmetic facial surgery. [2009.10]
OBJECTIVES: To compare the efficacy and side effects of ibuprofen and acetaminophen with codeine when given postoperatively following cosmetic facial surgery and to assess whether bruising is worse or the incidence of hematoma is greater when ibuprofen is taken postoperatively. DESIGN: Prospective, double-blind, randomized trial. SETTING: Accredited outpatient surgery centre... CONCLUSIONS: Ibuprofen 400 mg is as effective as acetaminophen/codeine 600/60 mg for pain relief following cosmetic facial surgery. Ibuprofen is better tolerated, with fewer side effects, than acetaminophen with codeine. Ibuprofen given postoperatively does not result in increased bruising or increased incidence of hematoma.

A Comparison of Postoperative Tramadol Versus Acetaminophen With Codeine in Children Undergoing Tonsillectomy [Completed]
Tonsillectomy is the most common pediatric surgical procedure performed in the US. The
postoperative period can be particularly painful. Codeine (usually in mixed formulation with
acetaminophen) is the most commonly prescribed opioid in the US. However, evolving data
questions its ability to provide optimal pain relief, while avoiding side effects,
especially in the postoperative setting. Tramadol may be a better option for children in the
postoperative setting due to its well-documented analgesic properties, low potential for
side effects, and excellent safety profile. Seventy-two children scheduled to undergo
tonsillectomy (with or without adenoidectomy) at Children's will be invited to participate
in a randomized, prospective, double-blinded study to evaluate the efficacy and side effects
of codeine with acetaminophen versus tramadol. Using a 10-day take-home diary, caregivers
will be asked to record daily information about their child's postoperative pain and other
core outcomes and domains as recommended in the recent consensus statement put forth by the
Pediatric Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials
(IMMPACT) (McGrath et al., 2008). This study will offer new information regarding the
efficacy and side effects associated with tramadol as compared with codeine/acetaminophen
(the current practice standard) in a pediatric population.
H1: Children who receive scheduled tramadol following tonsillectomy will report better pain
control than children who receive scheduled codeine/acetaminophen.
H2: Children who receive scheduled tramadol following tonsillectomy will report fewer side
effects than children who receive scheduled codeine/acetaminophen.
