Opioids are very useful medications to reduce suffering of cancer patients such as refractory pain and dyspnea. We physicians have to use opioids to have good management of pain and suffering associated with cancer including management of side effects caused by opioids. Opioids couple opioid receptors and affect several pharmacological effects. Other than analgesic effect, opioids have some side effects of constipation, nausea and vomiting, respiratory depression. In this chapter, I take important side effects of constipation, nausea and vomiting and respiratory depression...

Tramadol is a centrally acting analgesic drug able to prevent nociceptor sensitization when administered into the temporomandibular joint (TMJ) of rats. The mechanism underlying the peripheral anti-inflammatory effect of tramadol remains unknown. This study demonstrated that intra-TMJ injection of tramadol (500µg/TMJ) was able to inhibit the nociceptive response induced by 1.5% formalin or 1.5% capsaicin, suggesting that tramadol has an antinociceptive effect, acting directly on the primary nociceptive neurons activating the nitric oxide/cyclic guanosine monophosphate signaling pathway...

(no author information available yet)
Although premature ejaculation is the most common ejaculation problem, it is poorly understood and currently has no standard definition.(1) Typically, it involves reduced time to ejaculation, inability to control or delay ejaculation and associated distress.(1-5) Treatments that have been assessed include psychosexual counselling, antidepressants (e.g. selective serotonin reuptake inhibitors), phosphodiesterase type-5 inhibitors, tramadol and topical anaesthetic agents (e.g. lidocaine/prilocaine cream). A new formulation (cutaneous spray) of lidocaine/prilocaine (Fortacin-Plethora Solutions Ltd...

OBJECTIVE: There is substantial evidence that the use of opioids increases the risk of adverse outcomes such as delirium, but whether this risk differs between the various opioids remains controversial. In this systematic review, we evaluate and discuss possible differences in the risk of delirium from the use of various types of opioids in older patients. METHODS: We performed a search in MEDLINE by combining search terms on delirium and opioids. A specific search filter for use in geriatric medicine was used...

Capillary electrophoresis (CE) is an extremely effective technique in many kinds of separations, including separation of enantiomers. Some additional techniques may be necessary to determine the enantiomer migration order (EMO) and also the mechanism involved in chiral recognition. This paper reports the development and optimization of a CE method for enantioseparation of racemic mixture of both R- and S-stereoisomers of tramadol (TRM) with a computational contribution for the EMO determination and the responsible mechanisms for chiral distinction...

BACKGROUND: The combined use of tramadol with selective serotonin and norepinephrine reuptake inhibitors e.g. venlafaxine may be associated with serotonin syndrome. No previous studies exist examining the influence of a weak CYP2D6 inhibitor venlafaxine on the pharmacokinetics of tramadol. Therefore, the aim of this study was to determine the effect of a single and chronic administration of venlafaxine on the pharmacokinetics of tramadol using a rabbit model. METHODS: Adult New Zealand white rabbits of both sexes (n=21) were used...

BACKGROUND: Shock wave lithotripsy (SWL) is the first line treatment modality for a significant proportion of patients with upper urinary tracts stones. Simple analgesics, opioids and non-steroidal anti-inflammatory drugs (NSAIDs) are all suitable agents but the relative efficacy and tolerability of these agents is uncertain. OBJECTIVES: To determine the efficacy of the different types of analgesics used for the control of pain during SWL for urinary stones. MATERIALS AND METHODS: We searched the Cochrane Renal Group's Specialised Register, MEDLINE, EMBASE and also hand-searched reference lists of relevant articles (Figure-1)...

Background L-acetylcarnitine, a drug marketed for the treatment of chronic pain, causes analgesia by epigenetically up-regulating type-2 metabotropic glutamate (mGlu2) receptors in the spinal cord. Because the epigenetic mechanisms are typically long-lasting, we hypothesized that analgesia could outlast the duration of L-acetylcarnitine treatment in models of inflammatory and neuropathic pain. Results A seven-day treatment with L-acetylcarnitine (100 mg/kg, once a day, i.p.) produced an antiallodynic effect in the complete Freund adjuvant mouse model of chronic inflammatory pain...

Untreated and undertreated pain represent one of the most pervasive health problems, which is worsening as the population ages and accrues risk for pain. Multiple treatment options are available, most of which have one mechanism of action, and cannot be prescribed at unlimited doses due to the ceiling of efficacy and/or safety concerns. Another limitation of single-agent analgesia is that, in general, pain is due to multiple causes. Combining drugs from different classes, with different and complementary mechanism(s) of action, provides a better opportunity for effective analgesia at reduced doses of individual agents...

Tramadol is an analgesic drug and relieves pain through activating μ-opioid receptors and inhibiting serotonin and noradrenaline reuptake. Emerging evidence shows that it also stimulates immune cells, including NK cells, splenocytes, and lymphocytes, and elevates IL-2 production. However, it remains unknown whether and how tramadol directly affects macrophages. To answer these questions, we collected human umbilical cord blood, isolated macrophages, and examined their responses to tramadol. Although tramadol did not alter resting macrophages and the antigen-presenting function in lipopolysaccharide-activated macrophages, it regulated M1 and M2 macrophages, which are, respectively, transformed by IFN-γ and IL-4...
