WebSigmoid Emax model curves with different values of the Hill exponent. Theophylline is used to treat severe asthma. It is a bronchodilator. Airway constriction slows the peak flow rate … WebThe baseline is about 20%, and the maximum is 100%, so the EC50 is the concentration of agonist that evokes a response of about 60% (halfway between 20% and 100%). The concentration that provokes a response of 50 in this experiment is not the EC50. Don't over interpret the EC50. It is simply the concentration of agonist required to provoke a ...

WebAt the point where all the receptors are full, all we have to do is draw a line across to tell us the number of moles of drug per mg of protein that are bound. We have now made the assumption that one molecule binds with one receptor. We know the number of drug molecules we have got and the number of receptors we have got. WebThe E max model is a nonlinear model frequently used in dose–response analyses. The model is shown in Eq. (9.1) Keywords.
