Mastering Liquid Dosage Forms Quiz

Study Notes

Components in Liquid Dosage Forms

Solubilising agents help dissolve active pharmaceutical ingredients in liquid formulations, enhancing their bioavailability.
Colouring agents are used to impart aesthetic appeal and improve patient compliance in liquid dosage forms.

Advantages of Liquid Dosage Forms

Liquid dosage forms provide ease of swallowing, making them suitable for populations like children and the elderly.
They allow for rapid absorption and onset of action, which is beneficial for medications requiring quick relief.

Types of Liquid Dosage Forms

Solutions are more acceptable for local action due to their uniform distribution and immediate effect at the site of application.

Glycerine as a Vehicle

Glycerine serves as a sweetening and preservative agent in liquid dosage forms, providing a pleasant taste and stability in formulations.

Classification of Parenteral Suspensions

Parenteral suspensions can be classified based on the route of administration, such as intramuscular, subcutaneous, or intravenous.

Particle Size Range

The dispersed phase in pharmaceutical suspensions typically has a particle size range of 1 to 100 micrometers.
In emulsions, the particle size for the dispersed internal phase usually falls within a similar range to ensure stability and effectiveness.

Function of Suspending Agents

Suspending agents play a critical role in preventing sedimentation by increasing viscosity, thereby ensuring uniform distribution of solid particles in suspensions.

Disadvantages of Pharmaceutical Suspensions

Pharmaceutical suspensions may face challenges like poor stability, potential for caking, and difficulty in achieving homogeneous mixtures upon storage.

Size Range of Solid Particles

Solid particles within the internal phase of pharmaceutical suspensions generally range from 0.5 to 100 micrometers, facilitating appropriate therapeutic delivery.
