Question

Why are medicines more effective in the colloidal states?

Answer 1

Colloidal solution:-

• Colloidal solutions are a type of mixture in which microscopically dispersed insoluble particles of one substance are suspended into another substance.
• The size of such suspended particles in a colloid range from 1 to 1000 nanometres $({10}^{-9}\mathrm{metres}).$
• Due to the large surface area of the colloids, the medicine is much more effective in a colloidal state, as the drug particles are large in size.
• As a result these get easily absorbed in the tissues of our body.
• For example, antibiotics such as penicillin are injected into our bodies in a colloidal form.
