1. Therapy: Some colloidal dispersion show better therapeutic action and are used in treatment.
Silver colloid-germicidal Copper colloid - anticancer Mercury colloid - anti syphilis
2. Absorption and toxicity:
• Colloidal sulfur shows better and faster absorption compared to a coarse dispersion of sulfur.
3. Solubility: Solubility of drug is improved by using colloidal systems containing surface active agents.
4. Stability: Dispersion of surface active agent (associated colloids) are used to improve the stability of drugs in liquid dosage forms.
5. Targetting of the drug to the specific organs:
• Colloids are used in targeting the drug to specific body organs.
