Solution
The question is asking which of the given options is NOT a method used to enhance the skin penetration of a drug that is absorbed through the skin.
A. Electrophoresis is a method used in laboratories to separate charged particles. It can also be used to enhance the penetration of a drug through the skin by applying an electric field.
B. Chemical enhancers like acetone, DMSO or sodium lauryl sulfate are substances that can increase the permeability of the skin to a drug, thus enhancing its absorption.
C. Sonophoresis is a process that uses ultrasound to increase the permeability of the skin, thus enhancing the absorption of a drug.
D. Iontophoresis is a technique that uses a small electric charge to deliver a medicine or other chemical through the skin.
Therefore, all of the options A, B, C, and D are methods of enhancing the skin penetration of a percutaneously absorbed drug. The question seems to be incorrect as all the given options are methods used to enhance the skin penetration of a drug.
