Source: Depression News From Medical News Today [2013.12.05]
Type 2 diabetes has long been linked to higher risk of depression in women, and previous research has associated both of these conditions with pain. But a new study suggests that vitamin D supplementation can reduce both depression and pain in women with type 2 diabetes.

More than half of older adults in the United States - an estimated 18.7 million people - have experienced bothersome pain in the previous month, impairing their physical function and underscoring the need for public health action on pain. Many of those interviewed by investigators for a study published in the current issue of PAIN® reported pain in multiple areas.
Published Studies Related to Tramadol and Acetaminophen (Tramadol / Acetaminophen)
Pharmacokinetics of extended-release versus conventional tramadol/acetaminophen fixed-dose combination tablets: an open-label, 2-treatment, multiple-dose, randomized-sequence crossover study in healthy korean male volunteers. [2011.06]
BACKGROUND: A fixed-dose combination tablet of tramadol/acetaminophen exhibits both rapid and sustained analgesic effects due to different pharmacologic activities. To prolong analgesia and improve patient convenience, an extended-release (ER) tablet of this agent has been developed. OBJECTIVE: The aim of this study was to explore the pharmacokinetic profiles of the new ER tramadol/acetaminophen fixed-dose combination and compare them with those of a conventional immediate-release (IR) formulation after multiple dosing as a Phase I clinical exploratory trial... CONCLUSIONS: The ER formulation displayed a similar AUC(0-12,ss) to that of the IR formulation for tramadol and acetaminophen. Copyright (c) 2011 Elsevier HS Journals, Inc. All rights reserved.

The objective of this study was to compare the efficacy and effectiveness between an analgesic combination of tramadol/paracetamol (37.5+325 mg), and paracetamol monotherapy (1000 mg) for acute postoperative pain after hand and foot surgery. The study design was a single blind randomized controlled trial...
Effects of clonidine as premedication on plasma renin activity, serum and urine electrolytes and body fluids in general anesthesia. A randomized double blind placebo controlled clinical trial. [2011.02]
CONCLUSION: This study suggested that clonidine is a safe premedication drug in anesthesia and does not change the serum electrolytes level.
Analgesia with paracetamol/tramadol vs. paracetamol/codeine in one day-surgery: a randomized open study. [2011.02]
OBJECTIVES: The analgesic efficacy of two fixed combinations of tramadol/paracetamol (TP 37.5/325 mg) and codeine/paracetamol (CP 30/500 mg) was compared in 122 patients undergoing one-day surgical procedures (hallux valgus, haemorrhoidectomy, varicectomy and inguinal hernia repair), randomly treated with TP 37.5/325 mg or CP 30/500 mg one tablet after surgery ended, followed by one tablet four times daily for 48 hours... CONCLUSIONS: We conclude that a fixed association of tramadol/paracetamol is a valuable and safe tool for pain management in day hospital surgery, especially whenever any effort is done to reduce the time for hospitalization.
The efficacy of intravenous paracetamol versus tramadol for postoperative analgesia after adenotonsillectomy in children. [2011.02]
STUDY OBJECTIVE: To evaluate the efficacy and the quality of recovery with intravenous (IV) paracetamol versus tramadol for postoperative analgesia after adenotonsillectomy in children... CONCLUSIONS: The IV formulation of paracetamol was associated with similar analgesic properties and early recovery to that of IV tramadol after adenotonsillectomy in children.

Clinical Trials Related to Tramadol and Acetaminophen (Tramadol / Acetaminophen)
A Comparison of the Effectiveness and Safety of ULTRACET® (Tramadol Hydrochloride/Acetaminophen) Versus ULTRAM® (Tramadol Hydrochloride) Versus Placebo in Patients With Pain After Oral Surgery [Completed]
The purpose of this study is to explore the pain-relieving effects and safety of two
analgesic treatment regimens as compared to placebo in patients experiencing pain after oral
surgery. Tramadol hydrochloride/acetaminophen is approved to treat acute pain. This study
will evaluate the effectiveness and safety of tramadol hydrochloride/acetaminophen compared
with tramadol hydrochloride alone compared with placebo as a pain medication in the treatment
of pain following oral surgery.
Celebrex vs Tramadol in the Treatment of Chronic Lower Back Pain. [Completed]
This study investigates if Celebrex is as effective as tramadol hydrochloride (Ultram) for
patients with chronic low back pain, when administered over a 6-week period.
CYTRAM (Cytochrome P450, Tramadol) [Recruiting]
Many methods to detect CYP2D6 poor metabolizers have been validated. Some of them are based
on phenotyping (metabolism of dextromethorphan or debrisoquine) and some others on
genotyping. Up to now, CYP2D6 pharmacogenetics has been restricted to the field of research,
in spite of poor metabolizer profile concerns 5 to 10 % of caucasian population.
Nevertheless, the polymorphism of CYP2D6 is responsible for the metabolism of many drugs,
particularly of two opioids involved in pain management: codeine and tramadol, their
metabolites representing the most effective part of the drug effect. So prescribing codeine
or tramadol in a patient poor metabolizer for the CYP2D6 is likely to be ineffective in pain
O-demethyl-tramadol, the metabolite of tramadol via CYP2D6, is important to consider because
its analgesic effect is 2 to 4 times more potent than tramadol.
The investigators propose to phenotype CYP2D6 in post-operative patients treated by tramadol
by monitoring seric concentrations of O-demethyl tramadol and tramadol to make a ratio in
comparison with genotype, and to find a threshold to determine poor metabolizers. As already
described, genotyping CYP2D6 will use a rapid detection method of the alleles implicated in
poor metabolizer status (CYP2D6*3, *4, *5 et *6) in a Caucasian population. Sampling will be
executed at two times (H24 and H48 after surgery) and only with blood (three EDTA tubes)
during the post-operative monitoring of the patients. This study is likely to include 320
post-operative patients treated with intravenous tramadol during one year in three
university hospitals centers (CHU of Caen, CrÃ©teil and Rouen).
The first aim of this study is the validation of monitoring seric concentrations of
O-demethyl-tramadol and tramadol to make the ratio in order to detect CYP2D6 poor
metabolizers in therapeutic situation, comparing the result with genotyping. The finding of
a poor metabolizer status in a patient will make the choice of analgesic drugs easier,
avoiding tramadol and codeine. The final objective of this research is to be able to
determine the CYP2D6 phenotype in a patient treated by tramadol without a good analgesia. By
a single take of blood and a rapid response, this method should be liked to improve pain
management. Furthermore, CYP2D6 phenotyping is interesting for the patient because many
other drugs depend on this way of metabolism.
A Comparison of Postoperative Tramadol Versus Acetaminophen With Codeine in Children Undergoing Tonsillectomy [Recruiting]
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.
