Study Notes

Introduction to Pharmacology

Pharmacology is the study of drugs and their interactions with living systems.
It encompasses drug discovery, development, effects, and mechanism of action.
It involves understanding how drugs affect biological processes at the molecular level.

Drug Targets

Drugs typically interact with specific molecular targets within the body.
These targets are often proteins such as enzymes, receptors, ion channels, and transport proteins.
The specific target determines the drug's action and selectivity.

Pharmacokinetics

Pharmacokinetics describes how the body handles drugs.
It involves four key processes:
- Absorption: The process by which a drug enters the bloodstream.
- Distribution: The process by which a drug is transported throughout the body.
- Metabolism: The process by which a drug is chemically altered by the body.
- Excretion: The process by which a drug is eliminated from the body.

Pharmacodynamics

Pharmacodynamics describes how a drug alters the function of its target in the body.
It examines the relationship between drug concentration and the magnitude of effect.
It encompasses several factors, like receptor binding, signaling pathways involved, and mechanisms of drug action(pharmacological effects).
Primary drug effects are the intended therapeutic effects, while side effects are unintended consequences.

Drug Administration

Drug administration routes are crucial to achieving desired therapeutic outcomes.
Common routes include oral, intravenous (IV), intramuscular (IM), subcutaneous (SC), topical, and inhalation.
Each route influences the drug's absorption rate, bioavailability, onset of action, and duration of effect.

Drug Design and Development

Modern drug development involves a rigorous process of discovery and testing.
It typically involves numerous phases of preclinical and clinical trials to evaluate drug safety and efficacy.
Drug design focuses on creating molecules with enhanced potency, selectivity, and safety profiles.

Drug Classification

Drugs can be classified based on various factors.
- Their chemical structure
- Their mechanism of action
- Their therapeutic use(e.g., anti-inflammatory, analgesic)

Drug-Drug Interactions

When multiple drugs are administered together, they can interact, altering the effects and/or safety profile.
Interactions can lead to drug potentiation, drug antagonism, or altered metabolism.

Therapeutic Drug Monitoring (TDM)

In some cases, monitoring drug levels in the blood is essential for safe and effective treatment.
Proper TDM helps adjust dosage and ensures therapeutic levels without causing toxicity.

Adverse Drug Reactions (ADRs)

ADRs are unintended negative effects of a drug.
They can range from mild to severe.
Factors influencing ADRs include patient variables, drug dosage, and interactions with other drugs.

Drug Safety

Drug safety is a crucial aspect of pharmacology.
Thorough preclinical and clinical trials are required to assess the potential adverse effects of a drug.
Monitoring patients for ADRs during treatment is essential.

Special Populations

Factors such as age, gender, and pre-existing health conditions can affect how a drug is processed and acts within the body.
Specific considerations are often required to tailor medication regimens for different patient populations e.g., pediatric and geriatric patients.

Ethical Considerations

Ethical guidelines and regulations govern drug development, use, and research.
Ensuring patient safety and well-being is paramount.

Regulatory Bodies

Governmental bodies oversee the safety and efficacy of drugs.
Examples include the Food and Drug Administration (FDA) in the United States.

Drug-Nutrient Interactions

Food and beverages can affect how a drug is absorbed and ultimately metabolized.
These interactions can influence the drug's efficacy and safety profile.

Drug Compliance

Patient compliance with prescribed medication regimens is essential for successful treatment.
Factors influencing compliance include patient understanding of the therapy, accessibility to medication, and lifestyle factors.
