When a drug is taken by a patient, the resulting biological effects, for example lowering of blood pressure, are determined by the pharmacological properties of the drug. These biological effects are usually produced by an interaction of the drug with specific receptors at the drug’s site of action.. 1. /59. CONTENTS. 2. /59. INTRODUCTION. APPROACHES. EVALUATION.
