Pharma Exam Question:
What are six mechanisms of resistance from chemotherapeutic agents?
Answer:
1) Absence of Target (Ergosterol's absent)
2) Alterations in Target (Pen. Binding Protein Alterations)
3) Low concentration at target (Interference with membrane passage)
4) Lack of metabolic activation (Antifungal Flucytosine -> Fluorouracil)
5) Inactivation (Penicillinases)
6) Escape from Effect (Alternate Metabolic Pathways)
