Questions and Answers

What are the two main components of a disperse system?

The two main components are the dispersed phase, which is the undissolved or immiscible drug, and the dispersion media, which is the vehicle.

Differentiate between lyophilic and lyophobic colloids.

Lyophilic colloids have an affinity for the dispersion medium, whereas lyophobic colloids do not have such an affinity and are less stable.

What role do colloidal electrolytes play in pharmaceutical formulations?

Colloidal electrolytes act as surfactants, improving solubility and stability of formulations.

Why are natural and synthetic polymers important in pharmaceutical applications?

<p>Natural and synthetic polymers serve as pharmaceutical adjuvants, contributing to formulations that enhance therapeutic efficacy.</p> Signup and view all the answers

What is the significance of increasing therapeutic efficacy in dispense systems?

<p>Increasing therapeutic efficacy ensures that the drug achieves the desired therapeutic effect at lower doses, minimizing side effects.</p> Signup and view all the answers
