Solubility has a significant effect on drug efficacy. The solubility of a drug in water is a basic property that must be considered. The pharmacokinetic profile is important, especially for drugs with low solubility. Drugs taken orally will have a lower number of active drug compounds in the systemic circulation if the drug has low solubility, which also affects the bioavailability of the drug.
