Study Notes
Pharmacodynamics
- Investigates how drugs bind to receptors, considering the concentration and time required for a response.
- Analyzes the effect of drugs on the body and their interactions at receptor sites.
Pharmaceutical Chemistry
- Focuses on the synthesis of new drug molecules and the design of drugs aimed at optimizing pharmacokinetics (absorption, distribution, metabolism, excretion) and pharmacodynamics.
- Involves the study of molecular structures and their implications on drug effectiveness.
Pharmaceutics
- Centers on the design and formulation of drugs for optimal delivery to patients.
- Ensures stability, pharmacokinetics, and patient acceptance by studying various dosage forms.
Biopharmaceutics
- Examines the physical and chemical properties of drugs, as well as the appropriate dosages related to onset, duration, and intensity of therapeutic effects.
- Considers factors affecting drug action timing and effectiveness.
Pharmaceutical Equivalents
- Drug products are considered pharmaceutical equivalents when they share the same active ingredient(s), dosage form, route of administration, and strength or concentration.
- Examples include identical formulations like capsules or syrups with similar effectiveness.
Pharmacogenomics
- Studies the genetic patterns affecting interactions between drugs and organisms.
- Influences personalized medicine by tailoring drug therapy based on genetic profiles.
Pharmaceutical Toxicology
- Investigates the harmful or toxic effects of drugs on organisms.
- Aims to understand adverse reactions and the safety profiles of pharmaceutical compounds.
Pharmacokinetics
- Describes the science of absorption, distribution, metabolism, and elimination (ADME) of drugs.
- Focuses on the time required for each parameter to impact drug efficacy within the body.
Drug Interactions with Receptors
- Explores how drugs interact with their specific receptors over time and the resulting physiological effects.
- Involves monitoring and studying drug responses at the receptor level.
Antagonists
- Defined as drugs that bind to receptors but prevent activation by endogenous substances.
- Example: Naloxone is an opioid antagonist that blocks receptor activation, used in opioid overdose cases.
