Tramadol with or without paracetamol acetaminophen for cancer pain. The mean ages were 59 to 70 years, with participants aged between 24 and 87 years. Study length ranged from one day to six months. Five studies used a cross-over design. Tramadol doses ranged from 50 mg as single dose to mg per day; doses of mg per day to mg per day were most common. Nine studies were at high risk of bias for one to four criteria only one high risk of bias for size. We judged all the results to be very low quality evidence because of widespread lack of blinding of outcome assessment, inadequately described sequence generation, allocation concealment, and small numbers of participants and events.

Important outcomes were poorly reported. There were eight different active comparators and one comparison with placebo. There was little information available for any comparison and no firm conclusions could be drawn for any outcome. Single comparisons of oral tramadol with codeine plus paracetamol , of dihydrocodeine, and of rectal versus oral tramadol provided no data for key outcomes. One study used tramadol combined with paracetamol ; four participants received this intervention.

One study compared tramadol with flupirtine - a drug that is no longer available. One study compared tramadol with placebo and a combination of cobrotoxin, tramadol , and ibuprofen , but the dosing schedule poorly explained. Two studies participants compared tramadol with buprenorphine. One study participants reported a similar proportion of no or mild pain at 14 days. Three studies participants compared tramadol with morphine.

Only one study, combining tramadol , tramadol plus paracetamol , and paracetamol plus codeine as a single weak-opioid group reported results. Randomized comparative trial of efficacy of paracetamol , ibuprofen and paracetamol-ibuprofen combination for treatment of febrile children.

Directory of Open Access Journals Sweden. Full Text Available Objective: Paracetamol and ibuprofen are widely used for fever in children as monotherapy and as combined therapy. None of the treatments is proven clearly superior to others. Hence, the study was planned to compare the efficacy of paracetamol , ibuprofen and paracetamol-ibuprofen combination for treatment of febrile children. Materials and Methods: This was an investigator blind, randomized, comparative, parallel clinical trial conducted in 99 febrile children, 6 months to 12 years of age, allocated to three groups.

Patients were followed-up at intervals of 1, 2, 3 and 4 h post dose by tympanic thermometry. Highest fall of temperature was noted in the 1 st h of drug administration in all the groups. No serious adverse events were observed in any of the groups. Conclusion: Paracetamol and ibuprofen combination caused quicker temperature reduction than either paracetamol or ibuprofen alone.

Full Text Available Pain intensity may be high in the postoperative period after spinal vertebral surgery. The aim of the study was to compare the effectiveness and cost of patient controlled analgesia PCA with tramadol versus low dose tramadol-paracetamol on postoperative pain. A total of 60 patients were randomly divided into two groups. One group received 1. The bolus and infusion programs were adjusted to administer a 1 mL bolus dose of tramadol with a lock time of 10 minutes.

In Group P, 1 g of paracetamol was injected intravenously every 6 hours. The four-point nausea scale, numeric rating scale for pain assessment, Ramsey sedation scale, blood pressure, heart rate, respiration rate, peripheral oxygen saturation values and side effects were recorded at 0, 15 and 30 minutes, and at 1, 2, 4, 6, 12, 18 and 24 hours. The time to reach an Aldrete score of 9 was also recorded. A cost analysis for both groups was performed.

In Group P, the numeric rating scale scores were significantly lower than that in Group T at 0 and 15 minutes. The number of side effects, additional analgesic requirement and the total dose of tramadol were lower in Group P than in Group T. However, the total cost of postoperative analgesics was significantly higher in Group P than in Group T p tramadol-paracetamol could be used safely for postoperative pain relief after spinal vertebral surgery, although at a higher cost than with tramadol alone.

Effect of paracetamol injection on the analgesic effect of tramadol in Ibuprofen plus paracetamol versus ibuprofen in acute low back pain: a randomized open label multicenter clinical study.

Patients were followed for another 7 days. Efficacy and tolerability of both treatment options was assessed. A statistically significant decrease in pain intensity, assessed using a visual analogue scale pibuprofen monotherapy reported minor gastric intolerability. Background Both paracetamol and ibuprofen are commonly used analgesics for the relief of pain following the surgical removal of lower wisdom teeth third molars. In , a novel analgesic marketed as Nuromol containing both paracetamol and ibuprofen in the same tablet was launched in the United.

The detector was set at nm. Using such conditions, retention time for paracetamol and ibuprofen was 4. The recovery for paracetamol and ibuprofen was found to be The detector limits of the method was 1. Keywords: paracetamol , ibuprofen , multi-component, validation, HPLC. A comparative study of ibuprofen with paracetamol versus oxyphenbutazone with analgin combination in ophthalmic practice.

Full Text Available A total of patients of either sex with various ophthalmic inflammatory disorders of surgical and non-surgical types were treated with ibuprofen with paracetamol 1 tablet tid. A significantly lesserr number of patients in the ibuprofen with paraeetamol group required escape analgesics. Seventy six per cent of patients in the Ibuprofen with paracetamol group were judged as showing a Very good - Good, response to treatment as against 55 per cent in the oxvphenbutazone-analgin group.

It is concluded that ibuprofen with Paracetamol is superior in efficacy and a safer alternative to a combination of oxyphenbutazone and analgin.

The pharmacokinetic profile of a novel fixed-dose combination tablet of ibuprofen and paracetamol. Background Ibuprofen and paracetamol differ in their mode of action and related therapeutic effects, suggesting that combined administration may offer improved analgesia. Reported here are the results of two studies on the pharmacokinetic properties of a novel ibuprofen mg and paracetamol mg fixed-dose combination tablet.

Methods Both studies were open-label, randomised studies in healthy volunteers: Study 1 was a four-way crossover, single-dose study; Study 2 was a two-way cross Single dose oral ibuprofen plus paracetamol acetaminophen for acute postoperative pain.

Combining two different analgesics in fixed doses in a single tablet can provide better pain relief than either drug alone in acute pain. This appears to be broadly true across a range of different drug combinations, in postoperative pain and migraine headache. Some combinations of ibuprofen and paracetamol are available for use without prescription in some acute pain situations.

To assess the efficacy and adverse effects of single dose oral ibuprofen plus paracetamol for acute postoperative pain using methods that permit comparison with other analgesics evaluated in standardised trials using almost identical methods and outcomes. Randomised, double-blind clinical trials of single dose, oral ibuprofen plus paracetamol compared with placebo or the same dose of ibuprofen alone for acute postoperative pain in adults.

Two review authors independently considered trials for inclusion in the review, assessed quality, and extracted data. We calculated relative risk RR and number needed to treat to benefit NNT for ibuprofen plus paracetamol , ibuprofen alone, or placebo. We used information on use of rescue medication to calculate the proportion of participants requiring rescue medication and the weighted mean of the median time to use.

We also collected information on adverse events. Searches identified three studies involving participants. Each of them examined several dose combinations. Full Text Available Objective: to estimate whether combination of ibuprofen and paracetamol is more effective than ibuprofen in monotherapy, in the treatment of acute low back pain. Methods: 80 adult patients with acute low back pain were randomized into two subgroups.

Results: A statistically significant decrease in pain intensity, assessed using a visual analogue scale p. Simultaneous quantitative determination of paracetamol and tramadol in tablet formulation using UV spectrophotometry and chemometric methods. The UV spectrophotometric methods for simultaneous quantitative determination of paracetamol and tramadol in paracetamol-tramadol tablets were developed.

The spectrophotometric data obtained were processed by means of partial least squares PLS and genetic algorithm coupled with PLS GA-PLS methods in order to determine the content of active substances in the tablets. The results gained by chemometric processing of the spectroscopic data were statistically compared with those obtained by means of validated ultra-high performance liquid chromatographic UHPLC method.

The accuracy and precision of data obtained by the developed chemometric models were verified by analysing the synthetic mixture of drugs, and by calculating recovery as well as relative standard error RSE. The simplest and the most accurate and precise models were constructed by using the PLS method for paracetamol mean recovery Overview review: Comparative efficacy of oral ibuprofen and paracetamol acetaminophen across acute and chronic pain conditions.

Ibuprofen and paracetamol have long been used as analgesics in a range of acute, intermittent and chronic pain conditions. Paracetamol is often the first line analgesic recommended, without consensus about which is the better analgesic.

An overview review of systematic reviews and meta-analyses directly compares ibuprofen and paracetamol at standard doses in particular painful conditions, or uses indirect comparisons against placebo. Painful conditions were acute post-operative pain, dysmenorrhoea, tension-type headache TTH , migraine, osteoarthritis and rheumatoid arthritis, back pain, cancer and paediatric pain.

There was no systematic assessment of harm. Sixteen systematic reviews and four individual patient data meta-analyses were included. Ibuprofen was consistently superior to paracetamol at conventional doses in a range of painful conditions.

Two direct comparisons favoured ibuprofen acute pain, osteoarthritis. Three of four indirect comparisons favoured ibuprofen acute pain, migraine, osteoarthritis ; one showed no difference TTH , although there were methodological problems. In five pain conditions dysmenorrhoea, paediatric pain, cancer pain, back pain and rheumatoid arthritis , there were limited data on paracetamol and ibuprofen. At standard doses in different painful conditions, ibuprofen was usually superior producing more patients with the degree of pain relief that patients feel worthwhile.

Neither of the drugs will be effective for everyone, and both are needed. This overview questions the practice of routinely using paracetamol as a first line analgesic because there is no good evidence for efficacy of paracetamol in many pain conditions. The tramadol and paracetamol combination is used frequently for postoperative pain management.

The literature on the use of this combination for vertebral surgery is limited. Our main outcome measure was Visual Analogue Scale pain scores for 4 hours postoperatively.
