Pharmaceutical Aerosols

Definition of Pharmaceutical Aerosols

• Pharmaceutical aerosols are pressurized dosage forms that deliver medication as a fine mist, spray, or foam upon activation.

• The medication is dispersed in a suitable medium and propelled using compressed or liquefied gas.

Key Features

• Deliver the drug in a controlled and targeted manner, often directly to a localized site (e.g., the lungs, skin).

• Provide uniform and consistent dosing.

• Protect the formulation from environmental factors (moisture, oxygen, microbial contamination).

Applications:

1. Inhalation: For respiratory conditions (e.g., asthma, COPD).

2. Topical: For skin disorders or antiseptic use.

3. Nasal: For congestion or allergies.

4. Oral: For throat infections.
