Answer: the increased surface area aids in the better absorption of drugs.
Explanation: According to Noyes- Whitney equation, increased absorption of drugs depends on the rate of dissolution which is modified by altering the surface area. Reduction of the drug size from solid to powder form increases the specific surface area and the dissolution rate. This unique quantity makes it a fast acting medication since it's absorbed faster.
Many fast- acting medications are sold as powders, sometimes inside soluble capsules. Why would these medications act faster than solid tablets
it is a known fact that surface area affects digestion, soluble capsule which has been broken down to powdery form will penetrate faster than the solid ones which will take a longer time to get broken into particles before penetration.
the higher the solubility the higher the digestion or penetration of this drugs, thus; the faster the rate of its work vice versa
