Question

Which liquid dosage comes under monophasic liquid dosage

Answer 1

Answer:

Explanation:

Monophasic dosage form refers to liquid preparation containing two

or more components in one phase system, it is represent by true

solution.

• A true solution is a clear homogenous mixture that is prepared by

dissolving solute in a suitable solvent.

Answer 2

Answer:

Monophasic dosage form refers to liquid preparation containing two

or more components in one phase system, it is represent by true

solution.

• A true solution is a clear homogenous mixture that is prepared by

dissolving solute in a suitable solvent.

• The component of the solution which is present in a large quantity is

known as “SOLVENT” where as the component present in small

quantity is termed as “SOLUTE”.

Advantage

• It is easier to swallow, therefore easier for children and old age people.

• Facilitate absorption of drug faster than solid dosage form as drug is

already in solution form.

• It is homogenous therefore give uniform dose than suspension or

emulsion which need shaking.

• Simple and fast to formulate

• It can be administered by various routes :

Oral, Parenteral (injection),enema for rectal use, otic(ear), nasal and

ophthalmic preparation.

Disadvantage

• They are bulky, so difficult to transport and store.

• Water is commonly use vehicle, which is prone to microbial growth.

So addition of preservative is needed.

• When expose to direct sunlight it may undergo hydrolysis, so need to

store in cool and dark place.

• Drug stability reduce by hydrolysis or oxidation. So, they have shorter

expire date than solid dosage form.

• Other major sign of drug instability are color change, Precipitation,

microbial growth etc.
