"First is our research on the primary pharmacodynamics. This involves studying the drug's main pharmacological effects related to its clinical therapeutic action, using lab animals. We must conduct both in vivo and in vitro experiments... When selecting dosages, it's crucial to set up multiple dose groups to determine the effective range..."
"The observation period for the drug's efficacy should be determined by its rate of absorption, duration of action, and elimination time within the animal's body..."
"Second, general pharmacology research. In other words, studying the new drug's broader pharmacological effects, beyond its primary therapeutic actions."
