Why are some medicines more effective in the colloidal form ?

Options

A. the charged colloidal particles present in it
B. the large surface area and easy assimilation
C. precipitation of medicine in the blood
D. the stabilisation of medicine in colloidal form.

Explanation

**Step-by-Step Solution:**

1. **Understanding Colloidal Form**: Colloidal forms of medicines consist of tiny particles dispersed throughout a medium. These particles are larger than molecules but smaller than those in a suspension, typically ranging from 1 nm to 1 µm in size.

2. **Surface Area Consideration**: In the colloidal state, the particles have a significantly larger surface area compared to the same substance in a true solution. This increased surface area allows for more interaction with biological tissues.

3. **Assimilation in the Body**: The larger surface area of colloidal particles facilitates easier assimilation into the body. This means that the body can absorb and utilize the medicine more effectively when it is in a colloidal form.

4. **Effectiveness of Medicines**: Due to the combination of a larger surface area and enhanced assimilation, medicines in colloidal form can be more effective. They can act faster and provide better therapeutic effects compared to their counterparts in true solution.

5. **Conclusion**: Therefore, the effectiveness of some medicines in colloidal form can be attributed to their larger surface area and the ease with which they can be assimilated by the body.

**Final Answer**: Some medicines are more effective in the colloidal form due to their larger surface area and easier assimilation in the body.
