**Pharmacology Revision Cards** **Card 1: What is Pharmacology?** - Definition: The study of drugs, their effects on living organisms, and how they interact with biological systems. - Focus Areas: Drug actions, therapeutic effects, side effects, drug interactions, and the development of new medications. **Card 2: Drug Classification** - **Therapeutic Classification**: Categorizes drugs based on their therapeutic effects (e.g., analgesics, antibiotics, antihypertensives). - **Pharmacologic Classification**: Categorizes drugs based on their mechanism of action (e.g., beta-blockers, calcium channel blockers). - **Chemical Classification**: Based on the chemical structure of the drug (e.g., steroids, benzodiazepines). **Card 3: Routes of Drug Administration** - **Oral (PO)**: Common, easy, but slower onset. - **Intravenous (IV)**: Fast onset, 100% bioavailability. - **Intramuscular (IM)**: Moderate onset, used for depot formulations. - **Subcutaneous (SC)**: Slower than IV but can be used for self-administration (e.g., insulin). - **Topical**: Applied directly to skin (e.g., creams, patches). - **Inhalation**: Used for respiratory conditions (e.g., asthma medications). **Card 4: Drug-Receptor Interaction** - **Receptors**: Protein molecules that drugs bind to produce their effects. - **Agonists**: Drugs that bind to receptors and activate them to produce a biological response. - **Antagonists**: Drugs that bind to receptors but block or inhibit the action of agonists. - **Partial Agonists**: Drugs that bind to receptors and produce a submaximal response. **Card 5: Therapeutic Index** - **Definition**: The ratio between the toxic dose (TD50) and the therapeutic dose (ED50). - **Formula**: Therapeutic Index = TD50 / ED50. - A **larger therapeutic index** indicates a safer drug. - A **smaller therapeutic index** indicates a drug with a higher risk of toxicity. **Card 6: Drug Side Effects and Adverse Reactions** - **Side Effects**: Predictable, often non-harmful effects (e.g., drowsiness with antihistamines). - **Adverse Reactions**: Unintended harmful effects that may require dose adjustment or discontinuation of the drug. - **Allergic Reactions**: Immune response causing symptoms like rashes, swelling, or anaphylaxis. **Card 7: Drug Interactions** - **Pharmacokinetic Interactions**: Alterations in the absorption, distribution, metabolism, or excretion of a drug caused by another drug. - **Pharmacodynamic Interactions**: When one drug enhances or inhibits the effect of another drug at the receptor level. - **Synergistic Effect**: Two drugs working together to produce a greater effect. - **Antagonistic Effect**: One drug reduces the effect of another. **Pharmacokinetics Revision Cards** **Card 1: What is Pharmacokinetics?** - Definition: The study of how the body absorbs, distributes, metabolizes, and excretes drugs. - Focuses on the **ADME process**: Absorption, Distribution, Metabolism, Excretion. **Card 2: Absorption** - **Definition**: The process by which a drug enters the bloodstream. - **Factors Affecting Absorption**: - **Route of Administration** (oral, IV, etc.). - **Solubility**: Lipid-soluble drugs cross cell membranes easily. - **Blood Flow**: High blood flow increases absorption. - **pH and Ionization**: The pH of the drug and site affects absorption (e.g., acidic drugs are absorbed better in acidic environments). **Card 3: Bioavailability** - **Definition**: The fraction of the administered dose of a drug that reaches the systemic circulation. - **IV Administration**: Bioavailability = 100%. - **Oral Administration**: Bioavailability \< 100% due to first-pass metabolism in the liver. **Card 4: Distribution** - **Definition**: The process by which a drug is transported throughout the body to its site of action. - **Factors Affecting Distribution**: - **Blood Flow**: Drugs are distributed faster in well-perfused tissues. - **Plasma Protein Binding**: Some drugs bind to plasma proteins (e.g., albumin), which can affect their free (active) concentration. - **Tissue Affinity**: Lipophilic drugs tend to accumulate in fat tissues, while hydrophilic drugs accumulate in water-rich tissues. - **Blood-Brain Barrier**: Lipid-soluble drugs can cross into the brain more easily. **Card 5: Metabolism** - **Definition**: The chemical alteration of a drug in the body, primarily by the liver. - **Phases of Metabolism**: - **Phase I (Functionalization)**: Involves enzymes like CYP450, which add or expose functional groups (e.g., oxidation, reduction). - **Phase II (Conjugation)**: Involves adding a conjugate group (e.g., glucuronidation, sulfation) to make the drug more water-soluble. - **First-Pass Metabolism**: When a drug is metabolized in the liver before reaching systemic circulation (mainly relevant to orally administered drugs). **Card 6: Half-Life (t1/2)** - **Definition**: The time it takes for the concentration of a drug in the bloodstream to decrease by half. - **Factors Influencing Half-Life**: - **Metabolism Rate**: Faster metabolism reduces half-life. - **Excretion Rate**: Faster excretion reduces half-life. - **Volume of Distribution (Vd)**: Larger Vd typically increases half-life. - **Use**: Helps determine dosing intervals and steady-state concentrations. **Card 7: Excretion** - **Definition**: The removal of a drug and its metabolites from the body, primarily via the kidneys. - **Renal Excretion**: - **Glomerular Filtration**: Small, unbound drugs are filtered into urine. - **Tubular Secretion**: Active transport of drugs into the renal tubules. - **Tubular Reabsorption**: Lipid-soluble drugs are reabsorbed back into the bloodstream. - **Other Routes of Excretion**: Bile, sweat, saliva, and breast milk. **Card 8: Clearance** - **Definition**: The volume of plasma from which a drug is completely removed per unit of time. - **Formula**: Clearance (Cl) = Rate of Elimination / Plasma Drug Concentration. - **Factors Affecting Clearance**: - Liver and kidney function. - Blood flow to elimination organs. **Pharmaco-therapeutics Revision Cards** **Card 1: What is Pharmaco-therapeutics?** - **Definition**: The branch of pharmacology that deals with the use of drugs to treat diseases and the application of pharmacological principles to clinical practice. - **Focus Areas**: Drug selection, dosage, administration, therapeutic effects, side effects, and patient-specific factors influencing therapy. **Card 2: Adverse Drug Reactions (ADRs)** - **Definition**: Unintended, harmful reactions that occur at normal therapeutic doses. - **Types of ADRs**: - **Type A (Augmented)**: Predictable reactions based on the drug\'s pharmacological effects (e.g., drowsiness from antihistamines). - **Type B (Bizarre)**: Unpredictable reactions, often immune-mediated (e.g., anaphylaxis to penicillin). - **Type C (Chronic)**: Due to long-term use (e.g., steroid-induced osteoporosis). - **Type D (Delayed)**: Occur after a prolonged period (e.g., teratogenic effects of thalidomide). - **Type E (End of Treatment)**: Withdrawal symptoms (e.g., benzodiazepine withdrawal). **Card 3: Reporting Adverse Drug Reactions (ADRs)** - **Why Report ADRs**: - Helps identify new, rare, or long-term side effects. - Enhances patient safety by recognizing and preventing harm. - Supports regulatory bodies in evaluating drug safety. - **How to Report ADRs**: - Use the **Yellow Card Scheme** (UK) or similar systems depending on the country. - Report through healthcare providers, pharmacists, or online platforms. - Include relevant patient information, drug details, and the reaction experienced. **Card 4: Inverted Black Triangle Drugs** - **Definition**: Drugs that are subject to additional monitoring due to concerns about their safety. - **Black Triangle Symbol**: Indicates that a drug is under continuous review after its market authorization, typically because there is insufficient data on long-term safety. - **Example Drugs**: New medicines or biologics with limited post-market safety data (e.g., some vaccines, biologics like monoclonal antibodies). - **Special Reporting**: Healthcare professionals are required to report any suspected adverse reactions associated with these drugs, even if they are mild or uncommon. **Card 5: Reporting Side Effects Linked to Inverted Black Triangle Drugs** - **What to Report**: - Any suspected side effect, regardless of severity. - New or unexpected symptoms not listed in the product information. - Observed side effects in patients that may require changes to therapy. - **Importance**: Reporting helps generate more comprehensive safety profiles for these drugs, ultimately improving patient safety and informing future clinical practice. **Card 6: Concerns Around Drug Safety in Pharmaco-therapeutics** - **Types of Concerns**: - **Unpredictable or serious ADRs** that pose a risk to patient health. - **Substandard drugs** (e.g., counterfeit drugs or incorrect formulations). - **Drug interactions** that could lead to life-threatening consequences. - **Patient non-compliance** due to misunderstanding or difficulties with medication regimens. - **Over-prescription or misuse** of certain drugs (e.g., opioids). **Card 7: Whistleblowing in Healthcare** - **Definition**: Reporting concerns about unsafe practices, misconduct, or violations of regulations that could harm patients or the public. - **Context in Pharmaco-therapeutics**: Healthcare professionals may need to whistleblow when: - **Substandard or unsafe drugs** are being prescribed. - **Failure to report ADRs** or side effects associated with a drug. - **Unsafe clinical practices** that could endanger patient safety. - **Drug diversion** (e.g., misappropriation or misuse of controlled substances). **Card 8: Whistleblowing Procedures** - **Steps for Whistleblowing**: - **Identify the Issue**: Ensure there is a valid concern regarding patient safety or drug misuse. - **Internal Reporting**: Report concerns through internal channels (e.g., supervisors, managers, or clinical governance teams). - **External Reporting**: If internal channels are ineffective, escalate concerns to regulatory bodies (e.g., the Medicines and Healthcare products Regulatory Agency \[MHRA\] or the General Medical Council \[GMC\]). - **Confidentiality**: Maintain confidentiality, where possible, to protect both patient and whistleblower. **Card 9: Legal Protection for Whistleblowers** - **Whistleblower Protections**: - **UK**: The **Public Interest Disclosure Act (PIDA)** provides protection against dismissal or retaliation for workers who report unsafe practices in good faith. - **International Protections**: Various countries have similar laws that protect healthcare professionals from discrimination or retaliation after reporting concerns about drug safety or patient harm. -
