So, by adding a less volatile solvent, we will reduce the vapor pressure of the system, and subsequently, we will be able to produce large particles. g. Pulmonary suspensions/ Aerosols. Pump system for liquid antiseptics, germicides, nasal sprays. Three-phase system - This system is useful for topical pharmaceutical aerosols in that it allows a greater use of liquid components not miscible with the propellants. For most pharmaceutical aerosols, lung deposition is enhanced by a combination of aerosol particles <5m in diameter and a slow inhaled flow rate (20-30lmin1). for cleansing, preventing, disinfecting purposes. 7. We can confidently say that high vapor pressure is correlated with forming fine particles. for cleansing, preventing, disinfecting purposes. Here, the propellant is in the external phase of the emulsion. We use polyethylene glycol or propylene glycol monostearate as a solvent.

Unable to load your collection due to an error, Unable to load your delegates due to an error. Note that when one of the propellants is present in very low concentration then the ideal behavior is achieved. If we have a system having propellant 12, then add another propellant that has comparatively lower vapor pressure than propellant 12. They are preferred for use as a propellant over the fluorinated hydrocarbon based on their environmental acceptance and their lesser cost.

However , they are flammable and explosive. Conventional metered-dose systems can only deliver up to 10 to 15% of the dose. They can also be used for topical application of drugs and for systemic action as the drug can be absorbed through the lungs into the blood supply. It allows inhalation for a longer time which eliminates losses due to too rapid propulsion or inhalation. They are typically administered to patients using a nebulizer or other type of aerosol generator, such as a metered dose inhaler. By clicking Accept, you consent to the use of ALL the cookies. In aerosols, the pharmaceutically active ingredient is packed in a pressurized form. Raults law states that the decrease in the vapor pressure of solvent upon the addition of the solute is proportional to the mole fraction of the solute molecules in the solution. Before Important points to remember from the Pharmaceutical Aerosols chapter for GPAT/NIPER exams: In this article, I am going to provide important notes on aerosols that belong to the pharmaceutical dosage forms category. FOIA The following solutions can be applied: Aerosol emulsions are generally dispensed as a form. Add ethanol as a co-solvent to dissolve some amount of water in the propellant.
