Explanation of terms used by DrugBank

Water solubility

aqueous solubility, H20 solubility, solubility in water

Water solubility refers to the ability of a substance (or solute) to dissolve in water. In DrugBank, the water solubility of a drug is described in drug entries by using qualities such as "soluble" or "insoluble" or it is described by a numerical value in mg/mL or g/L units.

It is possible to find both [experimental], [predicted], and actual water solubility data in DrugBank, when this information is available. These values are obtained through sources such as ALOGPS, PhysProp, and others.
