4. Simple solution
Solubility is the amount of solute that will dissolve in a given amount of solvent
Drugs have different solubility in various solvent, some of drugs are freely soluble in water while other are the case.
Therefore, it is important to chose suitable solvent as vehicle in the preparation of a solution for medical use

5. Types of solutions Liquid in liquid solution Gas in liquid solution
Alcohol in water
Gas in liquid solution
Ammonia in water
Solid in liquid solution
NaCl in water

6. Classification according to method of preparation
Solution prepared by simple solution method
Solution prepared by chemical reaction
Solution prepared by simple method with sterilization like ophthalmic solution irrigation solution
Solution prepared by extraction

7. Classification according to their use
Mouth wash
Injection
Drop
Spray
Oral solution
enema

8. Preparation of simple solution
Weigh solid ingredient(s) and mix them together, then dissolve it in ¾ volume of the vehicle in a beaker or conical flask
Subtract any volume of liquid if exit in the prescription from ¾, and dissolve the solid ngredient in remainder of ¾.
After dissolution of solid ingredients, add any lquid ingredients if exit. Then complete the volume by adding of the vehicle
Keep prepared dosage form in a suitable container then label it

9. If the solid ingredients in form of crystalline ; mortar and pestle to grind it well so as to decrease particle size ( improving solubility of the solid by increasing surface area
Chose the solvent that dissolve solid ingredients easily ( like dissolve lik)
Pink label use for external preparations and white label for internal preparations
