Women are more emotional than males, for that reason particular medicines need less dosage in order to get the desired effect.
By using a linear scale, distortion in the curve on account of tolerance advancement is well seen. Nevertheless, as the dose-reaction curve is usually offered employing a logarithmic dose scale, this has also been adopted right here.
