Anatomy of the inhalation pathway

Describe how particle size influences delivery of a substance that is an inhalation aerosol and how it is related to airflow and the anatomy of the inhalation pathway. What is the optimal particle size of something that you want to deliver to the lungs (alveolar region)? What about a drug that you want to stay […]

Hydrophilic–lipophilic balance

When creating suspensions, you may want to include a surfactant of a specifc Hydrophilic–lipophilic balance(HLB) value. What does the Hydrophilic–lipophilic balance value of a substance refer to? For suspensions, what Hydrophilic–lipophilic balance value and category of surfactant could you want to target? List two examples of surfactants of HLB values in this range.

Solubility of drugs

What are three techniques that are used to enhance the solubility of drugs when preparing liquid dosage forms and what are some of their strengths and weaknesses? (NOTE: there are more than three techniques,  describe the strengths and weaknesses fully.)
