Abstract:
Over-expression of the human epidermal growth factor receptor 2 (HER2) protein, amplification of the HER2 gene or both occur in 15-25% of breast cancers and are associated with aggressive tumour behaviour. Trastuzumab (Herceptin), a humanized murine monoclonal antibody against the HER2 protein, has been shown to benefit patients with HER2-positive metastatic breast cancer when administered alone or in combination with chemotherapy. When to start therapy, the duration of treatment, adjuvant chemotherapy regimens and cardiotoxicity issues are examined.

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
