Classification, Advantage And Disadvantage Of Pharmaceutical Biphasic Liquid Dosage Form
Biphasic liquid dosage form is one that has two phases. This system consists of a solid dispersed state and a liquid continuous phase that can be aqueous or oily and is stabilized by the addition of a suspended agent. In this preparation this phase is called ‘dispersed phase’ and the vehicle is called ‘dispersed medium.’ It’s also called internal phase or external phase respectively. Biphasic liquid These are commonly taken orally or through the parenteral route, and they are also used for external applications. The need for biphasic liquid dosage forms arises when the medications are poorly soluble in the solvent medium.

Coarse particles, usually 1 - 100 microns in size 2. Fine dispersion containing particles of smaller size 3. And if the particles are in the colloidal range (< 1...
