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.

  • 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.

McCallum Joseph Sunny, Jr. Gastroparesis is characterized by delayed gastric emptying without mechanical obstruction of the gastric outlet or small intestine. The main etiologies are diabetes, idiopathic and post- gastric and esophageal surgical settings. The management of gastroparesis is challenging due to a limited number of medications and patients often have symptoms, which are refractory to available medications. This article reviews current treatment options for gastroparesis including adverse events and limitations as well as future directions in pharmacologic research. INTRODUCTION astroparesis is a syndrome characterized by documented gastroparesis are increasing.2 Physicians delayed emptying of gastric contents without have both medical and surgical approaches for these Gmechanical obstruction of the stomach, pylorus or patients (See Figure 1).

Actions on organ systems Describe the pharmacological effects of the drugs on gastric function. Are there effects on other organ systems?

Adverse effects, drug interactions and contraindications Describe the principal adverse effects of proton pump inhibitors. Describe the clinically important drug interactions of proton pump inhibitors. Describe the principal contraindications of proton pump inhibitors. Therapeutic uses Describe the current therapeutic uses of proton pump inhibitors. 1 Clinical Pharmacology Omeprazole is perceived to be the most potent of this drug class in inhibiting CYP2C19 activity and is proposed to have potential drug interactions with other drugs metabolized by this P450 isoform. Concern has been raised about potential inhibition of clopidogrel activation in patients taking both drugs concurrently. Current consensus is that in such patients clopidogrel with pantoprazole may be a safer choice to reduce the probability of a drug interaction involving CYP2C19.

    VETERINARY PRACTICE GUIDELINES 2020 AAHA Anesthesia and Monitoring Guidelines for Dogs and Cats* Tamara Grubb, DVM, PhD, DACVAAy, Jennifer Sager, BS, CVT, VTS (Anesthesia/Analgesia, ECC)y, James S. Gaynor, DVM, MS, DACVAA, DAIPM, CVA, CVPP, Elizabeth Montgomery, DVM, MPH, Judith A. Parker, DVM, DABVP, Heidi Shafford, DVM, PhD, DACVAA, Caitlin Tearney, DVM, DACVAA ABSTRACT Risk for complications and even death is inherent to anesthesia. However, the use of guidelines, checklists, and training can decrease the risk of anesthesia-related adverse events. These tools should be used not only during the time the patient is unconscious but also before and after this phase. The framework for safe anesthesia delivered as a continuum of care from home to hospital and back to home is presented in these guidelines. The critical importance of client commu- nication and staff training have been highlighted. The role of perioperative analgesia, anxiolytics, and proper handling of fractious/fearful/aggressive patients as components of anesthetic safety are stressed. Anesthesia equipment selection and care is detailed. The objective of these guidelines is to make the anesthesia period as safe as possible for dogs and cats while providing a practical framework for delivering anesthesia care. To meet this goal, tables, algorithms, figures, and “tip” boxes with critical information are included in the manuscript and an in-depth online resource center is available at aaha.org/anesthesia. (J Am Anim Hosp Assoc 2020; 56:---–---. DOI 10.5326/JAAHA-MS-7055) AFFILIATIONS Other recommendations are based on practical clinical experience and From Washington State University College of Veterinary Medicine, Pullman, a consensus of expert opinion.
