logarithm of the concentration of norepinephrine at which the force of blood vessel contraction is half the maximum value 
negative logarithm of the molar concentration of norepinephrine at which the force of blood vessel contraction is half the maximum value 
A calculated value for the negative logarithm of the concentration of norepinephrine at which the energy produced by the active reduction in the diameter of a blood vessel in response to the application of norepinephrine is half of the value of the highest achievable value of such norepinephrine-induced contractile energy. The logarithm of the concentration is the exponent indicating the power to which 10 must be raised to obtain that concentration value.
norepinephrine-induced blood vessel contractile force expressed as percent of force at baseline 
norepinephrine-induced blood vessel contractile force expressed as percent of force of contraction to KCL 

Synonyms
Exact Synonyms: NA pD2 ;   negative logarithm of the molar concentration of noradrenaline at which the force of blood vessel contraction is half the maximum value ;   noradrenaline -Log EC50
