General principles of pharmacology

Area of Science:

• Pharmacology
• Clinical Therapeutics
• Drug Development

Background:

• Historically, clinicians managed drug information; this is now delegated to pharmacists and pharmacologists.
• Current clinical practice emphasizes rational pharmacotherapy, focusing on the molecular mechanisms of drug action.
• All biologically active agents carry inherent risks, necessitating careful management of therapeutic dilemmas.

Purpose of the Study:

• To underscore the critical role of molecular pharmacology in modern clinical practice.
• To highlight the importance of understanding drug disposition, pharmacotherapeutics, and toxicology for clinicians.
• To emphasize the clinician's advantage when trained in the molecular basis of drug action.

Main Methods:

• Review of historical and current roles in drug management.
• Analysis of the principles of molecular drug action and homeostasis.
• Examination of the relationship between drug benefits and adverse effects.

Main Results:

• Drug information and dispensing roles have shifted from clinicians to pharmacists.
• Molecular-level understanding is fundamental for new drug development and rational pharmacotherapy.
• Adverse drug effects are an inherent aspect of all therapeutic agents.

Conclusions:

• Clinicians trained in molecular pharmacology, pharmacotherapeutics, and toxicology are best equipped to navigate therapeutic challenges.
• A thorough understanding of how drugs interact with the body at a molecular level is essential for optimal patient care.
• The inevitability of adverse effects underscores the need for expert clinical judgment in drug selection and management.
