PTCE Exam Dumps - PTCB CPhT Questions and Answers

AMaster Formulation Record (MFR)is adetailed document used in compounding pharmaciesto ensureconsistency, accuracy, and quality controlin preparing compounded medications.

An MFR includes:

Ingredients & amounts required.

Compounding procedures.

Stability and beyond-use dating (BUD).

Storage and labeling instructions.

This ensures that each compounded preparationmeets quality standardsand ismade correctly every time.

B. Prevent drug diversion❌→Incorrect

Drug diversion prevention involves security measures, inventory control, and trackingcontrolled substances, not MFRs.

C. Eliminate patient profiles❌→Incorrect

Patient profiles are essential for tracking medication history; MFRs are unrelated.

D. Guarantee drug availability❌→Incorrect

MFRs do not affect drug supply; they ensure accurate compounding.

Why Not the Other Options?Key References:

To determine theweight/weight (w/w) percentage strength, use the formula:

\text{w/w % strength} = \left( \frac{\text{Mass of Active Ingredient (g)}}{\text{Total Mass of Final Product (g)}} \right) \times 100

Given:

Mass of zinc oxide (active ingredient) = 4.5 g

Total mass of final ointment = 30 g

\text{w/w % strength} = \left( \frac{4.5}{30} \right) \times 100 =0.15×100= 0.15 \times 100=0.15×100 =15%= 15\%=15%

(A) 0.25%❌Incorrect – This is too low.

(B) 10%❌Incorrect – This would be true if 3 g of zinc oxide were used in 30 g total.

(C) 15%✅Correct – The calculation confirms this answer.

(D) 17.5%❌Incorrect – This would be true if 5.25 g of zinc oxide were used in 30 g total.

Carbon dioxide exposure can cause oxidation and degradation of certain medications, reducing theirstability and effectiveness.

????Reference:USP Drug Storage and Stability Guidelines.

Isotretinoin (Absorica, Claravis, etc.) is subject to a REMS program called iPLEDGE, required by the FDA to prevent fetal exposure due to high risk of teratogenicity. Female patients of reproductive age must:

Use two forms of contraception

Take monthly pregnancy tests

Receive special counseling and consent

From FDA REMS Guidelines:

“Isotretinoin is subject to a REMS program (iPLEDGE) due to its known, serious risk of severe birth defects if taken during pregnancy.”

Other options:

Clotrimazole – Antifungal, OTC and Rx; no REMS

Amitriptyline – Tricyclic antidepressant; no REMS

Tamsulosin – Used for BPH; no REMS
