Cimetidine
Pronunciation
Definition 1
A drug usually used to treat stomach ulcers and heartburn. It is also commonly used in a regimen to prevent allergic reactions. (NCI Dictionary)
Definition 2
A histamine H(2)-receptor antagonist. Enhancing anti-tumor cell-mediated responses, cimetidine blocks histamine's ability to stimulate suppressor T lymphocyte activity and to inhibit natural killer (NK) cell activity and interleukin-2 production. Cimetidine also may inhibit tumor growth by suppressing histamine's growth-factor activity and blocking histamine-induced stimulation of vascular endothelial growth factor (VEGF), a pro-angiogenic growth factor.
