83 ratings | 6215 views
Topic: Pharmaceutical Calculation Chapter: Colligative properties of solution and isotonicity The sodium chloride equivalent method (aka NaCl e-value method) is the most popular method of rendering an ophthalmic preparation isotonic. This video discusses the following: a) The concept of e-value of a drug. b) The general structure of questions that appear in NAPLEX and Pharmaceutics quizzes. c) Steps you need to follow to solve these problems. d) Making a preparation isotonic with the help of non-sodium chloride tonicity-adjusting agents, such as boric acid.

I like to thank Bensound (www.bensound.com) for their kind permission to use this royalty free background music. Note: the term "tonic" is used as a part of isotonic, hypertonic, hypotonic adjectives. However, 'tonicic' too is used as adjective when we mean strength or equivalent amount of something. This is not a typo in this video. Pages 175, 179, 182 of Ansel's Pharmaceutical Calculation (14th ed) have this term mentioned. Thanks for watching. Mamoon Rashid, PhD Appalachian College of Pharmacy
