Suspension is actually a colloidal technique owning good particles undissolved within the liquid period. The particle dimension of the sound particles in suspension is from the range of one μm.
The solute particles are evenly distributed all through the solvent process. This is among the significant advantages of this formulation.
Gels: Is made up of hydrophilic or hydrophobic foundation and gelling brokers. Transparent semisolid dose forms for exterior use.
