visceral pain/アサ属

BACKGROUND Many clinical pain states that are difficult to treat share a common feature of sensitization of nociceptive pathways. Drugs that could normalize hyperexcitable neural activity (e.g., antiepileptic drugs) may be useful in relieving these pain states. Eslicarbazepine acetate (ESL) is a

Endocannabinoids acting through cannabinoid receptor type 1 (CB1) are major modulators of peripheral somatic and visceral nociception. Although only partially studied, some evidence suggests a particular role of CB1 within the brain in nociceptive processes. As the endocannabinoid system regulates

Activation of cannabinoid receptors (CB(1), CB(2) and GPR(55)) produces analgesic effects in several experimental pain models, including visceral pain arising from the gastrointestinal tract. We assessed the role of CB(1), CB(2), and GPR(55) receptors and the endogenous cannabinoid system on basal

Marijuana derived from the plant Cannabis sativa has been used for the treatment of many gastrointestinal (GI) disorders, including anorexia, emesis, abdominal pain, diarrhea, and others. However, its psychotropic side effects have often limited its use. Several cannabinoid receptors, which include

Chronic pain is defined as pain that persists for more than three months.¹ It may present as headache, musculoskeletal pain, visceral pain, neuropathic pain, pain arising from rheumatic disease, and cancer pain.¹ Chronic pain is a global problem.² In Canada,

Combinations of nonsteroidal antiinflammatory drugs (NSAIDs) and opioids are widespread in the management of pain, allowing better analgesia with reduced side effects. Cannabinoids are promising analgesic drugs that have pharmacological properties similar to those of opioids. However, the beneficial

The identification of endocannabinoids and cannabinoid CB1 receptors in key areas of the intestinal wall, such as cholinergic neurons, supports a role for cannabinoids in the control of gastrointestinal motility. Activation of CB1 receptors inhibits the peristaltic reflex and slows down

BACKGROUND Cannabinoid receptors are involved in visceral pain perception and control of intestinal motility in vivo. The underlying mechanisms are not well characterized. We aimed to determine whether the cannabinoid-1 (CB(1)) receptor modulates intestinal afferent nerve discharge and the

BACKGROUND Constipation-predominant irritable bowel syndrome (IBS-C) is a common functional gastrointestinal (GI) disorder with abdominal pain and decreased motility. Current treatments of IBS-C are insufficient. The aim of this study was to evaluate the potential application of taranabant, a

Cannabis is widely used for treating a number of gastrointestinal ailments, but its use is associated with several adverse effects, particularly when the route of administration is via smoking. In the present study, we tested the effects (in rats) of a simple extract of medicinal cannabis (called

Mouse VD-hemopressin(α) (VD-Hpα) is an undecapeptide that selectively activates CB1 cannabinoid receptor in in vitro functional tests, and exerts CB1-mediated central antinociception in the mouse tail-flick assay. The aim of the present study was to further investigate the analgesic properties of

The gut immune, cannabinoid, and opioid systems constitute an integrated network contributing to visceral sensation and pain modulation. We aimed to assess the expression of the µ-opioid receptor (MOR), its ligand β-endorphin (β-END), and cannabinoid

Cannabinoids appear to possess many potential medical uses, which may extend to pain control. A narrative review of the literature has found a variety of studies testing botanical and synthetic cannabinoids in different pain syndromes (acute pain, cancer pain, chronic noncancer pain, fibromyalgia

BACKGROUND Chronic Pancreatitis (CP) is a complex and multifactorial syndrome. Many contributing factors result in development of dysfunctional pain in a significant number of patients. Drugs developed to treat a variety of pain states fall short of providing effective analgesia for patients with
