The intrinsic dissolution rate (IDR) is defined as the dissolution rate of a pure active substance, where the conditions of surface area, temperature, agitation, and medium pH and ionic strength are all constant.

The apparatus for testing intrinsic dissolution was originally developed in 1963 and is known as the Wood apparatus. The apparatus enables the calculation of the dissolution rate per sq/cm of the active ingredients of pharmaceutical products.
