Solubility of drugs
WebMay 8, 2024 · The bioavailability of a Class II drug can be markedly improved by improving its solubility: various methods to improve drug solubility are the focus of this chapter. The fact that about 40% of the top marketed drugs are practically insoluble, yet are nevertheless used commercially, is a testimony to the success of current solubilization methods. WebWhat is a lipid soluble drug? Because the cell membrane is lipoid, lipid-soluble drugs diffuse most rapidly. Small molecules tend to penetrate membranes more rapidly than larger ones. Most drugs are weak organic acids or bases, existing in un-ionized and ionized forms in an aqueous environment.
