Ondansetron Hydrochloride and Panixine

• Generic Name: ondansetron
• Dosage Forms: n.a.
• Other Brand Names: Zofran, Zofran ODT, Zuplenz

Prevention of nausea and vomiting associated with emetogenic cancer chemotherapy; may use orally with highly emetogenic chemotherapy (i.e., cisplatin ≥50 mg/m2) or initial and repeat courses of moderately emetogenic chemotherapy, or IV with initial and repeat courses of emetogenic chemotherapy, including high-dose cisplatin.

For prevention of nausea and vomiting associated with highly emetogenic chemotherapy regimens (including an anthracycline plus cyclophosphamide), ASCO recommends a 3-drug antiemetic regimen consisting of an NK1 receptor antagonist (e.g., either oral aprepitant or IV fosaprepitant), a 5-HT3 receptor antagonist (e.g., dolasetron, granisetron, ondansetron, palonosetron), and dexamethasone. ASCO states that fixed-combination netupitant and palonosetron plus dexamethasone is an additional treatment option.

For moderately emetogenic chemotherapy regimens, ASCO recommends a 2-drug antiemetic regimen preferably consisting of palonosetron and dexamethasone. If palonosetron is not available, a first-generation 5-HT3 receptor antagonist (preferably granisetron or ondansetron) may be substituted. Limited evidence suggests that aprepitant may be added to this regimen; in such cases, use of any 5-HT3 receptor antagonist is appropriate.

For chemotherapy regimens with a low emetogenic risk, ASCO recommends administration of a single dose of dexamethasone prior to chemotherapy.

For chemotherapy regimens with minimal emetogenic risk, ASCO states that routine antiemetic administration is not necessary.

Prevention of postoperative nausea and vomiting.

Routine prophylaxis not recommended in patients in whom there is little expectation that nausea and/or vomiting will occur postoperatively.

Recommended for patients who, in the clinician’s judgement, must avoid nausea and/or vomiting postoperatively, even when anticipated incidence is low.

Prevention of nausea and vomiting associated with radiation, either total body irradiation or single high-dose fraction or daily fractionated radiation to the abdomen.

Panitumumab injection is used alone or in combination with other medicines to treat metastatic cancer (cancer that spreads to other parts of the body) of the colon or rectum in patients who have already received other cancer treatments. Panitumumab injection should only be used in patients who have a wild type RAS (in both KRAS and NRAS) gene mutation test. This test helps the doctor decide whether the medicine will treat their cancer.

Panitumumab interferes with the growth of cancer cells, which are eventually destroyed by the body. Since the growth of normal body cells may also be affected by panitumumab, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects, such as a skin rash, may not be serious but may cause concern. Some effects do not occur until months or years after the medicine is used.

Before you begin treatment with panitumumab, you and your doctor should talk about the benefits of panitumumab as well as the risks of using it.

Panitumumab will only be given by or under the immediate supervision of your doctor.
