It can be prepared by the following methods (see also Figure 1): In the flash evaporation technique, a boiling concentrated solution of the poorly water-soluble drug and a water-soluble carrier in a suitable nonaqueous solvent is subjected to sudden vacuum, resulting in flash evaporation and the formation of a porous mass that, upon grinding, yields porous granules. The height to which water rises in a capillary depends on the capillary radius. The KorsmeyerPeppas model is plotted as the log cumulative percentage of drug release vs. log time. In 1961, Higuchi proposed the first mathematical model to describe drug release from a matrix system.27 .tabs.tabs-strip .tabs-title a[aria-selected='true'] { When mixed with a more polar solvent such as 2-propanol (propan-2-ol), the mixture is sufficiently polar to carry the ibuprofen through the inner layer of the skin, but not so polar that it will not dissolve ibuprofen. This low solubility makes ibuprofen much less able to dissolve in water than codeine. The dry product obtained from the test was crushed and passed through no. ; Masri, A.N. It can be also be expressed as: where C0 is the initial concentration of drug, k is the first-order rate constant, and t is the time.26 The resulting two-in-one product can greatly enhance the dissolution rate by simultaneously exploiting two techniques: solid dispersion and capillarity. Sometimes, ILs that possess high selectivity may not possess high capacities or vice versa. Kunov-Kruse, A.J. Enthalpy-entropy compensation analysis, showed that a nonlinear compensation existed between enthalpy and entropy due to variation in solvent composition and not to propagation of experimental errors.
