Subject Title
Dissolution Testing of Pharmaceutical Products

Subject Description
Starting with the history of dissolution testing of pharmaceutical products, this subject takes the student through the theory and concepts such as bioavailability and bioequivalence and in vivo and vitro correlation. Experiments are designed with emphasis on thorough understanding of the working of the apparatus, the experimental variables and their control in order to achieve consistent results. Beginning with the USP Apparatus I and Apparatus II to test immediate release products this hands on subject leads the student through dissolution profiling and dissolution testing of modified release tablets such as enteric coated and sustained release tablets with strong emphasis on the requirements of the United States Pharmacopeia, FDA and Health Canada. (Lectures and Labs)

Credit Status
One credit toward the Pharmaceutical Instrumentation Analyst (PIA) Certificate Program

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. Describe the role of Bio-availability and bio-equivalency in dissolution testing.

2. Describe the in-vivo in-vitro correlations (IVIVC) and its importance.

3. Set up disintegration apparatus and perform disintegration test according to USP <701>.

4. Assess the impact of various factors affecting dissolution testing.

5. Clearly understand the requirement of USP general chapter <711>.

6. Set up dissolution apparatus and perform dissolution tests as per USP.

7. Explain the principle of dissolution profiling and perform dissolution profiling.

8. Apply F2 similarity factor.

9. Perform dissolution for sustained release tablets.

10. Explain dissolution principles, requirements and apparatus for various dosage forms.

11. Document and report results.

Modes of Evaluation

  • Assignments are due at the beginning of the class on which they are due.
  • A late penalty of 10% per day is assessed for late assignments, including those not handed in at the beginning of class when due.
  • Material will not be accepted after one week following the due date and/or when the marked material is returned to students, whichever comes first.
  • Assignments are to be prepared by computer.

Absenteeism and Exams
  • Students should be aware that absenteeism almost guarantees an inability to achieve satisfactory grades.
  • Students who are absent for an examination due to an emergency (e.g., motor vehicle accident, hospitalization or death in the family) may provide official documentation within five days of the missed exam and be provided a deferred exam at a later date.  Official documentation includes a death notice or an original doctor’s certificate identifying the date, length of time expected absence and the specific reason for the absence.  Examinations missed without official documentation and approval result in a grade of zero.
  • There are no deferred options for missed tests.  The value of missed tests, at the discretion of the Faculty, will be added to other evaluation components

English Proficiency
  • All written work should demonstrate the following characteristics for clarity and conciseness:
-writing is consistent with the rules of English grammar
-spelling and punctuation are correct
-sentences are structured correctly
-main ideas are supported with specific, relevant examples and reasons
-work flows logically through supporting statements/paragraphs
-work is arranged in correct format (e.g., as a report, essay)
-up to 10% of the final grade may be deducted on all work if the above English competencies are not met.

Format for Assignments
  • Students must use the standard, APA style for quoting sources.   Help is available at:

Laboratory Attendance

The laboratory component is essential and therefore it is strongly recommended  that you attend all labs.  Any missed labs must be supported with a legal document with three days of the lab.  Any student who fails to attend 2 scheduled laboratory classes for a 7 week subject and more than 3 laboratory classes for a 14 week subject will not pass the subject.    

Laboratory Safety
Students are required to review and understand the safety procedures and guidelines outlined on the first class and sign the sheet to this effect before beginning work in the laboratory.  Students must also wear a lab coat and safety glasses when conducting experiments.
A student who arrives without the proper safety equipment will not be permitted to participant in the lab but will be asked to leave the class.  The student will receive no grade for the lab missed.

Grading is based on the following marking scheme:
Lab Report # 1 5%
Lab Report # 2 10%
Lab Report # 3 10%
Lab Report # 4 10%
Quiz 15%
Independent Study 10%
Final Exam  40%

Four lab reports are worth a total of 35% of the final mark. The reports are due one week after the work is completed.
The requirements for the reports are presented in writing at the beginning of the subject


Other Evaluation Considerations
The student is expected to comply with the Safety Rules for working in the laboratory, sign the safety contract, and WILL NOT UNDER ANY CIRCUMSTANCES WEAR CONTACT LENSES in the laboratory.  The student will know where all safety equipment is located in the laboratory and will be familiar with WHMIS concepts and signage.
