Questions and Answers

Which mechanism of drug action involves the drug serving as a precursor to neurotransmitters?

  • Antagonistic mechanism that inhibits synthesis of neurotransmitters
  • Mechanism that acts on the presynaptic neuron (correct)
  • Mechanism that stimulates the release of neurotransmitters
  • Antagonistic mechanism that prevents storage of neurotransmitters

Which mechanism of drug action inhibits the synthesis of neurotransmitters by inactivating the enzymes responsible for synthesizing precursor chemicals?
