The study of the biochemical and physiological effects of a drug on the body and its mechanism of action, summarised as 'what the drug does to the body'.
Pharmacodynamics (PD) is the study of the biochemical, physiological, and molecular effects of drugs on the body, including the relationship between drug concentration and pharmacological response. Key PD concepts include potency, efficacy, receptor occupancy theory, agonism vs antagonism, and the therapeutic window. For peptide research, PD analysis reveals how effectively a compound activates its target: tirzepatide demonstrates biased agonism at GIP receptors, while Ipamorelin shows selective GH secretagogue receptor activation without the broader hormonal effects of non-selective agonists. PK and PD are complementary disciplines that together inform optimal dosing strategies for peptide research.
The study of how the body absorbs, distributes, metabolises, and excretes a drug or peptide over time, often summarised as 'what the body does to the drug'.
The specific biochemical interaction through which a peptide or drug produces its pharmacological effect at the molecular or cellular level.
A molecule that binds to and activates a cellular receptor, mimicking or enhancing the effect of the natural signalling molecule (ligand).
The relationship between the quantity of a substance administered and the magnitude of its biological effect, fundamental to pharmacological research.
The physiological process of forming new blood vessels from pre-existing vasculature, essential for wound healing, tissue repair, and nutrient delivery.
A cellular self-cleaning process that degrades and recycles damaged organelles, misfolded proteins, and pathogens, crucial for longevity and cellular health.
