This study aimed to investigate the perioperative analgesic effect of a buprenorphine transdermal patch in patients who underwent simple lumbar discectomy.In total, 96 patients were randomly divided into parecoxib intravenous injection (Group A), oral celecoxib (Group B), and buprenorphine transdermal patch groups (Group C). The pain status, degree of satisfaction, adverse effects, and conditio...
Tramadol is one of the most widely used centrally acting analgesics worldwide. Because of its multimodal analgesic mechanism (opioid plus nonopioid), the adverse effects profile of tramadol, similar to its analgesic profile, can be atypical compared with single-mechanism opioid analgesics. The comparison is often favorable (e.g., less respiratory depression or abuse), but it is sometimes cited ...
A specific, rapid and simple UV spectrophotometric method with good sensitivity was developed and validated for the simultaneous quantification of tramadol HCl and paracetamol in bulk and marketed product by simultaneous equation method. From the optical characteristics of the proposed methods, it was found that the λmax of tramadol·HCl and paracetamol was found to 271 nm and 248 nm respectivel...
The aim of this study was to determine the pharmacokinetics of tramadol and its main metabolites after i.v. and i.m. injections. The pharmacokinetic cross-over study was carried out on 6 healthy male beagle dogs. Tramadol was administered by intravenous (i.v.) and intramuscular (i.m.) injection at 4 mg/kg. Tramadol and its main metabolites O-desmethyl-tramadol (M1), N-,N-didesmethyl-tramadol (M...
BACKGROUND Although arthroscopic shoulder surgery is less invasive and painful than open shoulder surgery, it can often cause intra-operative hemodynamic instability and severe post-operative pain. This study was conducted to investigate the efficacy of the interscalene brachial plexus block (IBPB) on intra-operative hemodynamic changes and post-operative pain during arthroscopic shoulder surge...
Tramadol hydrochloride, highly water soluble drug was chosen as candidate drug for formulation of controlled release drug delivery owing to its undesirable side effects like abdominal pain, anorexia which were likely to happen after administration of conventional drug delivery of tramadol. The objective of present study was to design and investigate the performance of hydrophilic and hydrophobi...
The metabolism of cis-tramadol has been studied in human liver microsomes and in cDNA-expressed human cytochrome P-450 (CYP) isoforms. Human liver microsomes catalyzed the NADPH-dependent metabolism of tramadol to the two primary tramadol metabolites, namely, O-desmethyl-tramadol (metabolite M1) and N-desmethyl-tramadol (metabolite M2). In addition, tramadol was also metabolized to two minor se...
In this study 50 samples of ecstasy tablets seized in Iran during the period of 2007 through 2008 were examined and their physical characteristics (appearance, marking, scored/not scored, color, weight, diameter, thickness) were determined. In order to determine the chemical characteristics of these tablets, color tests (Marquis test, Simon’s test, Chen’s test and Gallic acid test), Thin Layer ...
Tramadol, a centrally acting analgesic, consists of two enantiomers, both of which contribute to analgesic activity via different mechanisms. (+) Tramadol and the metabolite (+) -Odesmethyl-tramadol (M1) are agonists of the mu opioid receptor. (+) Tramadol also stimulates presinaptic release of serotonin and inhibits serotonin reuptake weheres (-) tramadol inhibits norepinephrine reuptake. Thus...
In most cancer patients, pain is successfully treated with pharmacological measures using opioid analgesics for moderate to severe pain (strong opioids) alone or in combination with adjuvant analgesics (coanalgesics). Opioids for mild to moderate pain (weak opioids) are usually recommended in the treatment of cancer pain of mild to moderate intensity. There is a debate whether the second step o...
