As we all know that diffusion is the process of mass transfer of an individual molecule of a material with the help of the concentration gradient. There are many important uses of diffusion testing in pharmacy which are listed below: 1. Drug absorption and elimination- With this technique people can actually get absorption and elimination of drugs. 2. Drug release from various dosage forms- Diffusion testing is done in order to test the speed at which the drug element is released from a tablet or capsules. 3. Ultrafiltration and dialysis- This testing also helps in removing the toxins along with excess water and salt from the kidney.
