Answer» Right option is (d) AMOUNT of solid substrate that GOES into solution under constant time under standard temperature, PH, solvent composition and constant surface area To explain: DISSOLUTION rate is defined as the amount of solid substrate that goes into solution under constant time under standard temperature, pH, solvent composition and constant surface area. It is a dynamic process. Drugs having poor aqueous solubility have LESS dissolution rate.
