Select all correct statements about the classification of drugs.

  1. AClassification by pharmacological effect groups drugs by the biomolecule they bind.
  2. BClassification by chemical structure groups drugs sharing a core skeleton even if their uses differ.
  3. COne drug can be placed in more than one classification, depending on the basis used.
  4. DClassification by molecular target groups drugs by the biomolecule they act on.

Answer: B, C, D

Pharmacological-effect grouping is by what the drug does, not by the molecule it binds (a false). Structure-based grouping can unite drugs with different uses (b true). The same drug can be classified by effect, action, structure or target (c true), and target-based grouping is by the biomolecule (d true).
