Legal Status: Prescription only product. VI.2 Elements for a public summary VI.2.1 Overview of disease epidemiology Nausea and vomiting associated with chemotherapy and radiotheraphy: One of the most distressing symptoms for patients undergoing both surgery and chemotherapy is nausea and vomiting. These symptoms have a significant impact on quality of life and can lead to malnutrition, inability to respond to treatment and an increased length of hospitalization. Emesis is more commonly associated with chemotherapeutic agents; however, radiation‐induced nausea and vomiting (RINV) can affect a significant proportion of patients, depending on the treated area, dose fractionation, and volume of radiotherapy. The relative risk for developing nausea and vomiting with chemotherapy ranges from 30 to 90% and is dependent upon the chemotherapeutic agent used. Relative risk for nausea and vomiting with radiation therapy is approximately 40%.2,3,4,5 Post‐operative nausea and vomiting Postoperative nausea and vomiting (PONV) is a major source of patient dissatisfaction and is the leading cause of discharge delays and unanticipated postsurgical hospital admissions. In the absence of pharmacological treatment, the rate of PONV is approximately 30% in general population, and can be as high as 70% in patients at highest risk. Several risk factors as surgery type, female gender, non‐smoker status, history of postoperative nausea and vomiting or motion sickness and post‐operative opioid use have been acknowledged. Additionally, post‐ operative vomiting (POV) occurs twice as frequently in children as in adults, increasing until puberty and then decreasing to adult incidence rates.

    INVESTIGATION OF NATURAL PRODUCT SCAFFOLDS FOR THE DEVELOPMENT OF OPIOID RECEPTOR LIGANDS By Katherine M.

Hanson _________________________________ Dr. Susan M. Lunte Date Defended: July 18, 2012 The Dissertation Committee for Katherine M. Prevatt-Smith certifies that this is the approved version of the following dissertation: INVESTIGATION OF NATURAL PRODUCT SCAFFOLDS FOR THE DEVELOPMENT OF OPIOID RECEPTOR LIGANDS _________________________________ Chairperson: Dr. Thomas E. Prisinzano Date approved: July 18, 2012 ii ABSTRACT Kappa opioid (KOP) receptors have been suggested as an alternative target to the mu opioid (MOP) receptor for the treatment of pain because KOP activation is associated with fewer negative side-effects (respiratory depression, constipation, tolerance, and dependence). The KOP receptor has also been implicated in several abuse-related effects in the central nervous system (CNS). KOP ligands have been investigated as pharmacotherapies for drug abuse; KOP agonists have been shown to modulate dopamine concentrations in the CNS as well as attenuate the self-administration of cocaine in a variety of species, and KOP antagonists have potential in the treatment of relapse. One drawback of current opioid ligand investigation is that many compounds are based on the morphine scaffold and thus have similar properties, both positive and negative, to the parent molecule. Thus there is increasing need to discover new chemical scaffolds with opioid receptor activity.

  • Therapeutic Class Overview Irritable Bowel Syndrome Agents
    Therapeutic Class Overview Irritable Bowel Syndrome Agents Therapeutic Class Overview/Summary: This review will focus on agents used for the treatment of Irritable Bowel Syndrome (IBS).1-5 IBS is a gastrointestinal syndrome characterized primarily by non-specific chronic abdominal pain, usually described as a cramp-like sensation, and abnormal bowel habits, either constipation or diarrhea, in which there is no organic cause. Other common gastrointestinal symptoms may include gastroesophageal reflux, dysphagia, early satiety, intermittent dyspepsia and nausea. Patients may also experience a wide range of non-gastrointestinal symptoms. Some notable examples include sexual dysfunction, dysmenorrhea, dyspareunia, increased urinary frequency/urgency and fibromyalgia-like symptoms.6 IBS is defined by one of four subtypes. IBS with constipation (IBS-C) is the presence of hard or lumpy stools with ≥25% of bowel movements and loose or watery stools with <25% of bowel movements. When IBS is associated with diarrhea (IBS-D) loose or watery stools are present with ≥25% of bowel movements and hard or lumpy stools are present with <25% of bowel movements. Mixed IBS (IBS-M) is defined as the presence of hard or lumpy stools with ≥25% and loose or water stools with ≥25% of bowel movements. Final subtype, or unsubtyped, is all other cases of IBS that do not fall into the other classes. Pharmacological therapy for IBS depends on subtype.7 While several over-the-counter or off-label prescription agents are used for the treatment of IBS, there are currently only two agents approved by the Food and Drug Administration (FDA) for the treatment of IBS-C and three agents approved by the FDA for IBS-D.
