The average values of Amiodarone and Phenytoin were used to convert compounds into low, medium and high solubility classes with the numerical values of 0, 1 and 2 respectively. With a nephelometer result lower than 50,000, which is the average value of Phenytoin, the molecules are classified as high soluble. Between 50,000 and 100,000 they end up in the medium class and with a value higher than the nephelometer average of Amiodarone (100,000) they were sorted in the class with low solubility.
