Introduction
Pharmacodynamics is a fundamental concept in pharmacology that explains how drugs act on the body to produce their effects. It involves drug interactions with cellular receptors, enzymes, and biochemical pathways. Understanding pharmacodynamics helps nurses ensure safe and effective medication administration while minimizing adverse effects.
Definition of Pharmacodynamics
Pharmacodynamics refers to the mechanism of action of a drug and its biological effects on the body. It describes how a drug binds to receptors, activates biological responses, and produces therapeutic or adverse effects.
Key Aspects of Pharmacodynamics
Drug-Receptor Interactions – How a drug binds to target receptors.
Dose-Response Relationship – The relationship between drug dose and its effect.
Drug Potency and Efficacy – The strength and effectiveness of a drug.
Mechanism of Action – The specific biochemical changes a drug induces.
Therapeutic and Adverse Effects – The desired and undesired effects of a drug.
1. Drug-Receptor Interactions
Most drugs bind to specific receptors to produce their effects. These receptors are usually proteins found on cell membranes or within cells.
Types of Drug-Receptor Interactions
Type
Description
Examples
Agonists
Drugs that activate receptors and produce a response.
Morphine (binds to opioid receptors for pain relief).
Partial Agonists
Drugs that activate receptors but produce a weaker response.
Buprenorphine (used for opioid addiction).
Antagonists
Drugs that block receptor activity and prevent a response.
Naloxone (blocks opioid receptors to reverse overdose).
Inverse Agonists
Drugs that bind to receptors and produce the opposite effect of an agonist.
Beta-blockers (e.g., Propranolol) (reduces heart rate by blocking adrenaline).
🔴 Nursing Considerations:
Monitor drug effects to determine if an agonist or antagonist is needed.
Check for receptor-specific side effects, such as excessive sedation from opioid agonists.
2. Dose-Response Relationship
The dose-response relationship explains how drug dosage affects its intensity of response.
Phases of Dose-Response Curve
Threshold Dose – The minimum dose needed to produce an effect.
Therapeutic Dose – The optimal dose that provides the desired response.
Toxic Dose – A high dose that causes toxicity.
✅ Example:
Low dose of Paracetamol (500 mg) → No effect on severe pain.
Standard dose (1000 mg) → Effective pain relief.
Overdose (5000 mg or more) → Toxicity and liver damage.
🔴 Nursing Considerations:
Administer drugs within the therapeutic range to avoid toxicity.
Monitor for signs of overdose or underdosing.
3. Drug Potency and Efficacy
A. Potency
Definition: The amount of drug needed to produce a specific effect.
A more potent drug requires a lower dose to achieve the same effect as a less potent drug.
✅ Example:
Fentanyl is more potent than Morphine (a smaller dose of Fentanyl provides the same pain relief).
B. Efficacy
Definition: The maximum effect a drug can produce.
A drug with higher efficacy can achieve greater therapeutic benefits.
✅ Example:
Ibuprofen has a higher efficacy than Paracetamol for reducing inflammation.
🔴 Nursing Considerations:
Monitor drug responses to ensure effectiveness.
Choose the correct drug based on both potency and efficacy.
4. Mechanism of Action
Drugs produce their effects through various mechanisms:
A. Stimulation or Depression
Stimulation: Increases activity of a body system.
Example: Caffeine stimulates the central nervous system (CNS) to increase alertness.
Depression: Reduces activity of a body system.
Example: Benzodiazepines (e.g., Diazepam) depress the CNS to induce sedation.
B. Replacement
Drugs replace deficient substances in the body.
Example: Insulin replaces missing insulin in diabetic patients.
Severe reaction (Anaphylaxis): Breathing difficulty after antibiotic injection.
🔴 Nursing Considerations:
Monitor therapeutic effects and adjust doses if needed.
Recognize early signs of toxicity or allergic reactions.
Document patient responses to medications.

Pharmacokinetics:
Introduction
Pharmacokinetics is an essential concept in pharmacology that describes how drugs move through the body from administration to elimination. Understanding pharmacokinetics helps nurses ensure safe and effective medication administration by considering factors like absorption, distribution, metabolism, and excretion.
Definition of Pharmacokinetics
Pharmacokinetics refers to the study of how a drug is absorbed, distributed, metabolized, and excreted (ADME) in the body. It determines the onset, duration, and intensity of a drug’s effect.
✅ Key Processes of Pharmacokinetics (ADME):
Absorption – How the drug enters the bloodstream.
Distribution – How the drug moves to different body tissues.
Metabolism (Biotransformation) – How the drug is broken down.
Excretion (Elimination) – How the drug is removed from the body.

Liter (L) or Milliliter (mL)
IV fluid 500 mL
Length
Meter (m), Centimeter (cm), Millimeter (mm)
Wound size 2 cm
✅ Metric Prefixes and Conversions:
1 kilogram (kg) = 1000 grams (g)
1 gram (g) = 1000 milligrams (mg)
1 milligram (mg) = 1000 micrograms (mcg)
1 liter (L) = 1000 milliliters (mL)
✅ Example Conversions:
500 mg = 0.5 g
250 mL = 0.25 L
75 mcg = 0.075 mg
🔴 Nursing Considerations:
Always double-check conversions before administration.
Use leading zeros (0.5 mg, NOT .5 mg) to avoid errors.
Never use trailing zeros (5 mg, NOT 5.0 mg) to prevent misreading.
2. Household System (Used for Patient Education)
The household system is used outside hospitals, mainly for liquid medications.
Common Household Measurement Conversions

5. Medication Dosage Calculations
Accurate dosage calculation is essential to prevent errors.
Basic Formula for Drug Dosage Calculation
Dose to be Given=(Desired DoseAvailable Dose)×Volume\text{Dose to be Given} = \left( \frac{\text{Desired Dose}}{\text{Available Dose}} \right) \times \text{Volume}Dose to be Given=(Available DoseDesired Dose)×Volume
Verify dosage with another nurse for high-risk medications (e.g., Insulin, Heparin).
Medication Dose Calculation:
Introduction
Accurate medication dose calculation is essential for patient safety in nursing. Incorrect dosage can lead to underdosing (ineffective treatment) or overdosing (toxicity or adverse effects). Nurses must be skilled in drug calculations to ensure safe and precise medication administration.
Basic Formula for Drug Dosage Calculation
The standard formula used to calculate drug dosages is: Dose to be Given=(Desired DoseAvailable Dose)×Volume\text{Dose to be Given} = \left( \frac{\text{Desired Dose}}{\text{Available Dose}} \right) \times \text{Volume}Dose to be Given=(Available DoseDesired Dose)×Volume
✅ Components of the Formula:
Desired Dose – The amount of drug prescribed by the physician.
Available Dose – The strength of the drug on hand.
Volume – The liquid volume containing the available dose (in mL).
Solid medications (tablets/capsules) require conversion based on the available dosage.
Formula:
Number of Tablets=Desired DoseAvailable Dose\text{Number of Tablets} = \frac{\text{Desired Dose}}{\text{Available Dose}}Number of Tablets=Available DoseDesired Dose
Never split enteric-coated or sustained-release tablets.
Verify dosages with another nurse for high-risk medications.
2. Liquid Medication Dosage Calculation
Liquid medications are measured in mL and require accurate conversions.
Formula:
Volume to be Given=(Desired DoseAvailable Dose)×Volume\text{Volume to be Given} = \left( \frac{\text{Desired Dose}}{\text{Available Dose}} \right) \times \text{Volume}Volume to be Given=(Available DoseDesired Dose)×Volume
Monitor fluid balance and IV site for complications.
5. Insulin Dosage Calculation
Insulin is measured in units (U) and requires precise dosing.
✅ Example Calculation:
Order: Give 12 units of regular insulin subcutaneously.
Available Dose:100 units per mL.
12100=0.12 mL\frac{12}{100} = 0.12 \text{ mL}10012=0.12 mL
✅ Answer: Draw up 0.12 mL using an insulin syringe.
🔴 Nursing Considerations:
Use ONLY insulin syringes.
Verify insulin doses with another nurse before administration.
6. Heparin Dosage Calculation
Heparin is a high-alert medication used to prevent blood clots.
✅ Example Calculation:
Order: Give 5000 units of Heparin IV.
Available Dose:10,000 units per 1 mL.
(500010000)=0.5 mL\left( \frac{5000}{10000} \right) = 0.5 \text{ mL}(100005000)=0.5 mL
✅ Answer: Draw up 0.5 mL for IV administration.
🔴 Nursing Considerations:
Double-check calculations with another nurse.
Monitor PTT (Partial Thromboplastin Time) for bleeding risk.
