When comparing the effectiveness of antiemetics, the "gold standard" is the 5-HT3 antagonist ondansetron. Unless otherwise indicated, anti-emetic regimens are used to prevent nausea and vomiting after a one-day chemotherapy with one of the cytostatics having this degree of emetogenicity. When using a combination of cytostatics, the emetogenicity of therapy is usually (if not specifically indicated) determined by the most emetogenic drug included in its composition, distinguish between high-, medium-, low-emetogenic and minimally emetogenic drugs.

Highly emetic chemotherapy

When performing highly emetic therapy, the risk of developing vomiting without adequate antiemetic therapy is> 90%. Drugs that have a highly emetic potential:

  • preparations for intravenous administration of cisplatin, cyclophosphamide> 1500 mg / m 2, carmustine, dacarbazine,
  • preparations for oral administration of procarbazine (Natulan).

Medium emetic chemotherapy

The risk of vomiting during medium emetic chemotherapy without adequate antiemetic therapy is 30-90%.

Medicines with a moderate emetic effect

  • preparations for intravenous administration of oxaliplatin, cytarabine> 1000 mg / m 2, carboplatin, ifosfamide, cyclophosphamide <1500 mg / m 2, doxorubicin, daunorubicin, epirubicin, idarubicin, irinotecan,
  • preparations for ingestion of cyclophosphamide, etoposide, imatinib.

Low-emetic chemotherapy

The risk of vomiting during low-emetogenic chemotherapy without adequate antiemetic therapy is 10-30%.

Medications with low emetogenic effect:

  • preparations for intravenous administration of paclitaxel, docetaxel, topotecan, etoposide, methotrexate, mitomycin, cytarabine <100 mg / m2, 5-fluorouracil, cetuximab, trastuzumab,
  • preparations for ingestion of capecitabine, fludarabine.

Minimally emetogenic chemotherapy

When conducting minimally emetogenic chemotherapy, the risk of developing vomiting without antiemetic therapy is <10%. Preparations with a minimally emetogenic effect:

  • preparations for intravenous administration of bleomycin, busulfan, fludarabine, vinblastine, vincristine, bevacizumab,
  • preparations for ingestion of thioguanine, phenylalanine, methotrexate, gefitinib, erlotinib.

When taking these medications, routine antiemetic prophylaxis is not used. It should be noted that the given recommendations refer only to prevention in patients receiving the first course of chemotherapy with these drugs. In the event that a patient has nausea and vomiting in the presence of the recommended prophylaxis, nausea and vomiting should be used in subsequent courses, and antiemetic prophylaxis recommended for a higher level of emetogenicity should be used.
