By rearranging this equation and taking logs we can form “log(Par/(1-Par))=[A]-logKA” from which we can see that plotting log (Par/1-Par)) against log [A] forms what is known as a hill plot‚ which consists of a straight line with a slope of unity. If the relationship between drug concentration and tissue response is directly proportional‚ the relationship between occupancy and response can be denoted as Y/100= Par which can be substituted into the previous equation to provide log(y/(100-y))=log[A]-log[KA]
