Biological Activity

Phentolamine mesylate is safe and effective in the long-term treatment of men with mild to moderate ED. Phentolamine increased catecholamine release by presynaptic alpha 2-blockade, thereby suppressing the autoinhibition of transmitter release. Phentolamine leads to an increase in FBM by preferentially antagonizing presynaptic alpha 2-adrenoreceptors over postsynaptic alpha 1-adrenoreceptors. This influence of phentolamine on FBM may be secondary to its effect on ECoG. Promotion of LV-ECoG by catecholamines is mediated via an alpha 1-independent mechanism.
