Study Notes
Pharmacology Overview
- Pharmacology studies medications and their interactions with living systems to produce therapeutic effects.
- New medications are continually being developed to combat diseases like infections, cancer, heart failure, and depression.
Drug Development Process
-
Step 1: Discovery
- A candidate compound is identified as a potential treatment for a specific disease.
-
Step 2: Preclinical Research
- Conducted through testing on cell cultures and animal models (e.g., mice, rats) to assess safety and potential harm.
-
Step 3: Clinical Development
- Involves three phases of clinical trials to evaluate safety and efficacy in humans.
Clinical Trials Phases
-
Phase I
- Tests the medication on a small group of healthy individuals to determine safety.
-
Phase II
- Evaluates the efficacy by testing on a moderate group affected by the condition at specific dosages.
-
Phase III
- Compares the new medication to standard treatments in a larger group to assess its effectiveness and safety in real-life conditions.
-
Phase IV
- Post-marketing surveillance to monitor long-term effects and rare side effects; may lead to recalls if safety issues arise.
Timeframe and Naming of Medications
- The medication development process can take over 10 years.
- Medications typically have three names:
- Chemical Name: Describes chemical structure (e.g., N-acetyl-p-aminophenol).
- Generic Name: Shortened version of the chemical name used by health professionals (e.g., paracetamol).
- Brand/Trade Name: Names given by pharmaceutical companies (e.g., Panadol, Tylenol).
Interaction with the Body
- Once administered, medications interact with the body through two main concepts:
- Pharmacokinetics: The study of how the body absorbs, distributes, metabolizes, and excretes drugs.
- Pharmacodynamics: The study of the biochemical and physiological effects of drugs and their mechanisms of action.
