Olanzapine for Nausea After Surgery

July 7, 2020 updated by: Jaime B Hyman

Olanzapine for the Treatment of Post-Discharge Nausea and Vomiting After Ambulatory Surgery

Ambulatory surgery is occurring with rapidly increasing frequency as surgical and anesthetic techniques have improved and pressure to reduce health-care costs has increased. While there are many benefits to recovering from surgery within the home, a significant disadvantage is the lack of rapid access to a healthcare provider when postoperative complications occur. Postoperative nausea and vomiting (PONV) are common after surgery and anesthesia, and recent studies have demonstrated a high incidence of post-discharge nausea and vomiting (PDNV) after ambulatory surgery, particularly in high-risk groups (female gender, age less than 50 years, history of PONV, opioid administration in the post-anesthesia care unit (PACU), and nausea in the PACU). Current practices known to reduce the risk of postoperative nausea and vomiting in the PACU, such as the avoidance of volatile anesthetics and the use of intraoperative ondansetron and steroids, have little effect on the risk of delayed PDNV. Novel strategies to prevent PDNV are needed. Orally administered olanzapine, which has been shown to decrease the incidence of chemotherapy-induced nausea and vomiting, demonstrates promise as a novel strategy for preventing PDNV. It has a long half-life, allowing for a single dose to be administered preoperatively. This study will evaluate whether there is a difference in the incidence and severity of PDNV between patients who receive oral olanzapine versus placebo prior to general anesthesia for ambulatory surgery.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
