For gastric, lung, colorectal and liver cancer; raises blood pressure. Updated Nov 1, 2026 ## Quick facts **Group** [Antineoplastic monoclonal antibodies](https://durgical.com/en/pharmacology/classes/antineoplastic-monoclonal-antibodies/) **Target** Vascular endothelial growth factor receptor 2 (VEGFR2, KDR) on endothelial cells **Used for** Advanced or metastatic gastric **Key effects** High blood pressure · Diarrhoea **Monitor** Blood pressure at every visit · Urine protein **ATC** L01FG02 No doses: the clinician sets them by the current guideline.

Ramucirumab is a human IgG1 antibody that binds VEGFR2 and blocks its ligands from binding, so endothelial cells are not stimulated and new vessel growth is held back. Unlike bevacizumab, which traps the VEGF ligand, it blocks the receptor. - Ramucirumab binds VEGFR2 on endothelial cells - VEGF can no longer activate the receptor - Tumour blood-vessel growth is held back ## Indications - Advanced or metastatic gastric or gastro-oesophageal junction adenocarcinoma after earlier chemotherapy, alone or with paclitaxel. [Gastric cancer →](https://durgical.com/en/conditions/gastric-cancer/) - Metastatic non-small cell lung cancer: with docetaxel after platinum chemotherapy, or with erlotinib first line when EGFR is mutated. [Lung cancer →](https://durgical.com/en/conditions/lung-cancer/) - Metastatic colorectal cancer with FOLFIRI after bevacizumab, oxaliplatin and a fluoropyrimidine. [Colorectal cancer →](https://durgical.com/en/conditions/colorectal-cancer/) - Hepatocellular carcinoma with high alpha-fetoprotein after sorafenib. [Hepatocellular carcinoma →](https://durgical.com/en/conditions/hepatocellular-carcinoma/) ## Adverse effects ### Common - High blood pressure - Diarrhoea - Mouth and throat sores - Swelling and weight gain; headache, tiredness ### Serious (rare, important) - Bleeding, including gastrointestinal bleeding and coughing or vomiting blood - Arterial clots: stroke and heart attack - Poor wound healing - Protein in the urine (foamy urine) - Infusion reactions; severe headache, confusion, seizures or vision loss ## Contraindications - No absolute contraindications in the label apart from hypersensitivity; see the warnings ## Key interactions **Paclitaxel, docetaxel, erlotinib or FOLFIRI (combination regimens)** Intended combinations; the toxicities of each drug add up (for example low blood counts and diarrhoea). ## What is monitored - Blood pressure at every visit - Urine protein - Thyroid and liver function - Signs of bleeding and wound healing ## Administration and safety - Intravenous infusion by a doctor or nurse in a hospital or clinic; the patient is watched for infusion reactions. - Any unhealed wound, or a planned surgery or dental procedure, is reported to the treating team first. ## Pregnancy and breastfeeding Avoid in pregnancy. A pregnancy test is done before starting and contraception is used during treatment and for months after; it may reduce female fertility, and breastfeeding is avoided. ## Nursing care - Check blood pressure before each dose. - Ask about high blood pressure, thyroid or liver disease and unhealed wounds before starting. - Teach the signs of stroke and heart attack, and to report bleeding, black stools, severe abdominal pain or foamy urine. - Tell the surgeon or dentist before any procedure. ## Pharmacokinetics **Absorption** Intravenous infusion every two to three weeks. **Half-life** About 14 days (mean). ## Memory aid RAMucirumab RAMS the RECEPTOR (VEGFR2); bevacizumab grabs the ligand (VEGF). Both: blood pressure, bleeding, wounds, protein in urine. ## Test yourself Think of the answer, then tap the question to see it. ## How does ramucirumab differ from bevacizumab? Ramucirumab blocks the receptor VEGFR2; bevacizumab binds the VEGF ligand. ## Which vital sign must be checked before every ramucirumab dose? Blood pressure. ## A patient on ramucirumab notices foamy urine. What does it suggest? Protein in the urine, a known effect of VEGF pathway blockade; urine protein is checked.
