Exam 1--Introduction Flashcards
What is the focus of pharmaceutics II?
The design and development of various SAFE and STABLE dosage forms or drug delivery systems.
When a patient receives a medication, what is always done?
It is always administered through a dosage form or a drug delivery system.
What type of relationship is shown by a zero order process?
Non-linear.
What type of relationship is shown by a first order process?
Linear
What determines the expiration date of a drug?
The physical-chemical stability of the drug.
What is the most common expiration date?
2 years
What does flow depend on? What dosage form is it important in?
- Viscosity
* Important in liquid dosage forms
What are some examples of surface phenomenon?
- adsorption
- hygroscopicity
- surface tension
- interfacial tension
What are some examples of colligative properties?
- vapor pressure
- freezing point
- osmotic pressure
(role in isotonic solutions, calculation of osmolarity, and mEq)
What is considered to be a conventional solid dosage form?
- tablets that are immediate release (IR).
- powder as a dosage form
- hard and soft gelatin capsules
What two categories are solid dosage forms divided into?
- conventional solid dosage forms
* modified release or controlled release dosage forms
Describe a solution.
One phase, liquid, clear, and transparent.
Describe a suspension.
Two phases, powder is dispersed uniformly into a liquid medium.
Describe an emulsion.
Two phases (oil phase and aqueous phase), dispersed uniformly.
If you have a dosage form that contains an aqueous phase, what should you consider adding to it and why?
- preservatives
* without it, the dosage form can contain bacteria
