Q: Propellants are important component of
  • A. Ocusert
  • B. Osmotic pump
  • C. Aerosols
  • D. Sustained release tablets
Correct Answer: Option C - A propellants help to develop pressure within the container and expel the products in the form of vapor in the formulation or aerosols A propellants is a chemical with a vapor pressure greater than atmospheric pressure at 40°C (105 °F). The propellant provides the force that expels the product can concentrate from the container and additionally is responsible for the delivery of the formulation in the proper form (i.e. spray, foam, semisolid) types of propellants commonly used in pharmaceutical aerosols.
