Question
Posted on: March 6 2013Doubt about the amount of isorbidenitraat to use 40%.
If a doctor proposes a prescription for a preparation with isosorbide Dinitrate 1 gram, should one use 1 gram or 2.5 gram of the product, which is only available in a trituration of 40% in the market? The rumor does the round that one can only use 1 gram because the packaging is "standardized"! And is this so for e.g. zinc peroxide trituration of approximately 55% and for Alpha tocopherol acetate to Vit E 500mg/g?
Answer
Who does all that wrong information interspersed? The CLI ë Nten are to complain! With one pharmacist a much stronger preparation as with another! Of course, the packaging is standardized.
here as an example the composition of the 1% isosorbidenitate ointment, which will be published in the TMF. I suspect that 1 example is sufficient?
R/Isosorbide dinitrate and trituration à 40% 1.25 g
paraffin Liquid 2.50 g
Vaseline Blanche Q.S. ad 50g
