Drug Nomenclature:

Introduction

Drug nomenclature refers to the systematic way of naming medications to ensure clarity, standardization, and global recognition. Understanding drug nomenclature is essential for nurses, pharmacists, and healthcare professionals to prevent confusion and medication errors.


Definition of Drug Nomenclature

Drug nomenclature is the process of assigning names to medications based on chemical structure, therapeutic use, or standardized guidelines set by international organizations.


Types of Drug Names

Drugs have multiple names depending on their classification, development process, and usage. The three main types of drug names include:

1. Chemical Name

  • The chemical name describes the molecular composition and structure of the drug.
  • It is based on International Union of Pure and Applied Chemistry (IUPAC) rules.
  • It is primarily used by scientists and researchers, not commonly used in clinical practice.

Example: N-acetyl-para-aminophenol (Chemical name for Paracetamol)


2. Generic Name (Non-Proprietary Name)

  • The generic name is the official name given to a drug by regulatory agencies.
  • It is simpler than the chemical name and is universally recognized.
  • Assigned by organizations such as United States Adopted Names (USAN) Council and World Health Organization (WHO) International Nonproprietary Names (INN).
  • Generic drugs contain the same active ingredient as brand-name drugs but are often cheaper.

Example: Paracetamol (Generic name for Tylenol)
Example: Ibuprofen (Generic name for Advil)


3. Brand Name (Proprietary Name/Trade Name)

  • The brand name is given by a pharmaceutical company and is trademarked.
  • It is easy to remember and used for marketing and sales purposes.
  • A single generic drug can have multiple brand names.

Example: Tylenol, Panadol, Crocin (Brand names for Paracetamol)
Example: Brufen, Advil, Motrin (Brand names for Ibuprofen)


Differences Between Generic and Brand Names

FeatureGeneric NameBrand Name
OwnershipPublic (No patent)Owned by a company
StandardizationInternationally recognizedCompany-specific
CostLess expensiveMore expensive
IngredientsSame active ingredient as the brandSame active ingredient but may have different fillers/preservatives
ExamplesParacetamolTylenol, Panadol, Crocin
IbuprofenBrufen, Advil, Motrin

International Organizations Involved in Drug Nomenclature

Several regulatory agencies oversee the naming of drugs to ensure standardization and global safety:

  1. World Health Organization (WHO) – International Nonproprietary Names (INN)
    • Assigns generic names for drugs internationally.
  2. United States Adopted Names (USAN) Council
    • Standardizes generic drug names in the USA.
  3. British Approved Names (BAN)
    • Assigns drug names in the United Kingdom.
  4. Japanese Accepted Names (JAN)
    • Regulates drug names in Japan.
  5. International Union of Pure and Applied Chemistry (IUPAC)
    • Establishes rules for chemical drug names.

Examples of Drug Nomenclature

Chemical NameGeneric NameBrand Name
N-acetyl-para-aminophenolParacetamolTylenol, Panadol
Acetylsalicylic acidAspirinDisprin, Bayer
2-(4-isobutylphenyl)propanoic acidIbuprofenBrufen, Advil
Sildenafil citrateSildenafilViagra
Atorvastatin calciumAtorvastatinLipitor

Why is Drug Nomenclature Important in Nursing?

  1. Prevents Medication Errors – Standardized names reduce confusion and ensure correct administration.
  2. Facilitates Communication – Healthcare professionals can communicate clearly using generic names.
  3. Ensures Patient Safety – Nurses must recognize both generic and brand names to avoid duplicating medications.
  4. Aids in Drug Education – Helps nurses educate patients about the correct medication.
  5. Regulatory Compliance – Nurses must follow hospital policies that often prefer generic drug names.

Effects of Drugs:

Introduction

Drugs are substances used to diagnose, treat, cure, prevent, or manage diseases. When administered, drugs interact with the body to produce different effects. Understanding the effects of drugs is crucial in nursing to ensure safe and effective patient care.


Definition of Drug Effects

The effects of drugs refer to the physiological and biochemical changes that occur in the body after a drug is administered. These effects can be therapeutic (desired) or adverse (undesirable) depending on the drug’s action, dose, and patient response.


Types of Drug Effects

1. Therapeutic Effects (Desired Effects)

  • These are the intended effects of a drug that help in treatment, prevention, or diagnosis of a disease.
  • Therapeutic effects depend on:
    • Drug mechanism of action (how the drug works).
    • Dosage and frequency of administration.
    • Patient’s age, weight, and health condition.

Examples:

  • Antibiotics (e.g., Amoxicillin) → Kill bacterial infections.
  • Antihypertensive drugs (e.g., Amlodipine) → Lower blood pressure.
  • Painkillers (e.g., Paracetamol) → Relieve pain and fever.

2. Side Effects

  • These are mild, expected, and often tolerable effects that occur along with the therapeutic action of a drug.
  • Side effects do not require discontinuation of the drug unless severe.

Examples:

  • Antibiotics → Can cause nausea or diarrhea.
  • Painkillers (NSAIDs like Ibuprofen) → Can cause stomach irritation.
  • Antihistamines (e.g., Diphenhydramine) → Can cause drowsiness.

3. Adverse Drug Reactions (ADR)

  • These are unexpected, harmful, and potentially dangerous effects of a drug.
  • Adverse reactions may require dose adjustment or discontinuation of the drug.
  • Some ADRs can be life-threatening (e.g., anaphylaxis, severe liver damage).

Examples:

  • Penicillin allergy → Causes severe rash, breathing difficulty.
  • Aspirin overdose → Leads to stomach bleeding or ulcers.
  • Antipsychotic drugs (e.g., Haloperidol) → Can cause involuntary muscle movements (tardive dyskinesia).

4. Toxic Effects (Drug Toxicity)

  • Occurs when a drug is administered in excessive doses or when the body cannot eliminate it properly.
  • Toxicity can cause serious organ damage or life-threatening conditions.

Examples:

  • Paracetamol overdose → Causes liver failure.
  • Digoxin toxicity → Leads to severe heart rhythm disturbances.
  • Opioid overdose (e.g., Morphine) → Causes respiratory depression.

🔴 Nursing Responsibility:

  • Monitor dosages and drug levels (e.g., monitoring INR for Warfarin therapy).
  • Recognize early signs of toxicity and report immediately.

5. Cumulative Effects

  • Occurs when a drug builds up in the body due to slow metabolism or excretion.
  • Often seen in elderly patients, liver/kidney disease patients.
  • Can lead to toxicity if not managed properly.

Examples:

  • Digoxin accumulation → Causes irregular heartbeat.
  • Sedatives accumulation → Causes excessive drowsiness, confusion.

6. Tolerance

  • A condition where the body becomes less responsive to a drug over time, requiring higher doses for the same effect.
  • Common in chronic medication users (e.g., painkillers, sedatives).

Examples:

  • Opioid tolerance (e.g., Morphine) → Patients need higher doses for pain relief.
  • Sleeping pills (Benzodiazepines) → Require increased doses for effectiveness.

7. Drug Dependence (Addiction)

  • A condition where the patient develops a physical or psychological need for the drug.
  • Stopping the drug suddenly leads to withdrawal symptoms.

Examples:

  • Narcotics (e.g., Heroin, Morphine) → Cause addiction.
  • Caffeine addiction → Causes headaches, irritability when stopped.
  • Benzodiazepines (e.g., Diazepam) → Can lead to dependence.

🔴 Nursing Responsibility:

  • Educate patients on the safe use of medications.
  • Monitor for signs of drug dependence.
  • Support patients in gradual dose reduction.

8. Idiosyncratic Reactions (Unpredictable Effects)

  • These are rare, unusual, and unpredictable responses to drugs.
  • Can be genetic or due to individual sensitivity.

Examples:

  • Antibiotics causing seizures in some individuals.
  • Sleeping pills causing hyperactivity in some patients instead of drowsiness.

9. Allergic Reactions (Hypersensitivity Reactions)

  • The immune system overreacts to a drug, leading to symptoms ranging from mild to severe.

Types of Allergic Reactions:

  1. Mild Allergic Reactions – Rash, itching, runny nose.
  2. Severe Allergic Reactions (Anaphylaxis) – Difficulty breathing, swelling, drop in blood pressure.

Examples:

  • Penicillin allergy → Can cause severe rash and swelling.
  • Aspirin allergy → Can cause asthma attacks.

🔴 Nursing Responsibility:

  • Check for patient allergy history before giving medications.
  • Keep emergency drugs (e.g., Epinephrine, Antihistamines) ready.

Factors Influencing Drug Effects

Several factors affect how a drug works in the body:

  1. Age – Infants and elderly patients metabolize drugs differently.
  2. Body Weight – Drug dosage is adjusted based on patient weight.
  3. Genetics – Some individuals have genetic variations that affect drug metabolism.
  4. Liver and Kidney Function – Impaired function can lead to drug accumulation.
  5. Route of Administration – IV drugs act faster than oral drugs.
  6. Drug Interactions – Some drugs can enhance or reduce each other’s effects.
  7. Psychological Factors – Placebo effect can influence drug response.

Nursing Responsibilities in Managing Drug Effects

  1. Assess the patient before and after drug administration.
  2. Monitor for adverse effects and toxicity.
  3. Educate patients on proper medication use and potential side effects.
  4. Ensure proper dosage calculation to prevent overdose.
  5. Recognize drug interactions and report any concerns.
  6. Document all medication administration and patient responses.

Forms of Medications:

Pharmacodynamics:

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

  1. Drug-Receptor Interactions – How a drug binds to target receptors.
  2. Dose-Response Relationship – The relationship between drug dose and its effect.
  3. Drug Potency and Efficacy – The strength and effectiveness of a drug.
  4. Mechanism of Action – The specific biochemical changes a drug induces.
  5. 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

TypeDescriptionExamples
AgonistsDrugs that activate receptors and produce a response.Morphine (binds to opioid receptors for pain relief).
Partial AgonistsDrugs that activate receptors but produce a weaker response.Buprenorphine (used for opioid addiction).
AntagonistsDrugs that block receptor activity and prevent a response.Naloxone (blocks opioid receptors to reverse overdose).
Inverse AgonistsDrugs 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

  1. Threshold Dose – The minimum dose needed to produce an effect.
  2. Therapeutic Dose – The optimal dose that provides the desired response.
  3. 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.

C. Inhibition or Killing of Microorganisms

  • Drugs destroy bacteria, viruses, or fungi.
    • Example: Antibiotics (e.g., Penicillin) kill bacterial infections.

D. Modification of Immune Response

  • Some drugs alter the immune system.
    • Example: Steroids suppress inflammation in autoimmune diseases.

🔴 Nursing Considerations:

  • Understand the mechanism of action before administering a drug.
  • Monitor for expected and unexpected reactions.

5. Therapeutic and Adverse Effects

A. Therapeutic Effects (Desired Effects)

  • Definition: The intended, beneficial effects of a drug.
  • Example: Paracetamol reduces fever.

B. Adverse Effects (Undesired Effects)

  • Definition: Harmful, unintended effects of a drug.
  • Examples:
    • Gastric irritation from NSAIDs (e.g., Aspirin).
    • Drowsiness from antihistamines.

C. Toxic Effects

  • Occurs when a drug accumulates in the body at harmful levels.
  • Example: Digoxin toxicity causes heart rhythm disturbances.

D. Allergic Reactions

  • Definition: Immune system overreaction to a drug.
  • Examples:
    • Mild reaction: Skin rash from Penicillin.
    • 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.

Factors Affecting Pharmacodynamics

Several factors influence how a drug works in the body:

FactorEffect on Drug ResponseExample
AgeChildren and elderly patients are more sensitive to drugs.Elderly patients need lower doses of sedatives.
Body WeightHigher body weight may require a higher drug dose.Obese patients may need more anesthesia.
GeneticsSome people metabolize drugs differently.Asians metabolize alcohol slower.
Liver and Kidney FunctionImpaired function affects drug metabolism and excretion.Kidney disease prolongs drug action.
Drug InteractionsSome drugs enhance or block each other’s effects.Alcohol increases the sedative effect of sleeping pills.
Route of AdministrationIV drugs act faster than oral drugs.IV morphine relieves pain faster than tablets.

🔴 Nursing Considerations:

  • Adjust doses based on age, weight, and organ function.
  • Monitor for drug interactions when multiple medications are prescribed.

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):

  1. Absorption – How the drug enters the bloodstream.
  2. Distribution – How the drug moves to different body tissues.
  3. Metabolism (Biotransformation) – How the drug is broken down.
  4. Excretion (Elimination) – How the drug is removed from the body.

1. Absorption

Absorption is the process by which a drug moves from the site of administration into the bloodstream.

Factors Affecting Drug Absorption

FactorEffect on AbsorptionExample
Route of AdministrationIV drugs absorb fastest, while oral drugs take longer.IV morphine works faster than oral tablets.
Drug FormulationLiquids absorb faster than tablets.Syrups act faster than capsules.
Food and pHSome drugs need food; others need an empty stomach.Iron absorbs better with Vitamin C.
Blood Flow to Absorption SiteMore blood flow increases absorption.Heat increases absorption of insulin.
Lipid SolubilityFat-soluble drugs absorb better than water-soluble ones.Anesthetic gases dissolve in fat for rapid action.

Fastest to Slowest Drug Absorption by Route:
IV > Inhalation > Sublingual > Intramuscular > Subcutaneous > Oral > Topical

🔴 Nursing Considerations:

  • Give drugs via correct route for desired absorption.
  • Monitor food-drug interactions (e.g., avoid dairy with tetracyclines).
  • Ensure patient positioning (e.g., sit upright for oral medications).

2. Distribution

Distribution is the movement of a drug from the bloodstream to body tissues where it acts.

Factors Affecting Drug Distribution

FactorEffect on DistributionExample
Blood CirculationHigher blood flow increases distribution.Brain, liver, kidneys get drugs faster than skin.
Protein BindingSome drugs bind to proteins like albumin.Warfarin binds to albumin; only free drug is active.
Blood-Brain BarrierOnly certain drugs cross into the brain.Lipid-soluble drugs like Diazepam cross easily.
Fat and Water ContentFat-soluble drugs accumulate in fat.Anesthesia lasts longer in obese patients.

Areas with High Blood Flow (Rapid Drug Action)

  • Heart
  • Liver
  • Kidneys
  • Brain

Areas with Low Blood Flow (Slow Drug Action)

  • Skin
  • Fat
  • Bone

🔴 Nursing Considerations:

  • Adjust drug doses in malnourished or obese patients.
  • Monitor for drug toxicity in patients with low albumin levels (e.g., liver disease).
  • Be cautious with blood-brain barrier drugs (e.g., sedatives).

3. Metabolism (Biotransformation)

Metabolism is the process of breaking down a drug into active or inactive forms, mainly in the liver.

Key Metabolism Site:

  • Liver (Primary site of drug metabolism)

Other Metabolism Sites:

  • Kidneys
  • Lungs
  • Intestines

Factors Affecting Drug Metabolism

FactorEffect on MetabolismExample
Liver FunctionLiver disease slows metabolism, increasing drug levels.Cirrhosis can cause drug toxicity.
AgeNeonates and elderly metabolize drugs slowly.Reduce dosage of sedatives in elderly patients.
GeneticsSome people metabolize drugs faster/slower.Some Asians metabolize alcohol poorly.
Enzyme Induction/InhibitionSome drugs speed up or slow down metabolism.Rifampin increases metabolism of oral contraceptives.

First-Pass Effect:

  • Definition: Some oral drugs are metabolized by the liver before reaching circulation, reducing their effect.
  • Example: Nitroglycerin is given sublingually to bypass first-pass metabolism.

🔴 Nursing Considerations:

  • Check liver function (LFTs) before giving drugs.
  • Avoid high first-pass effect drugs orally (e.g., Nitroglycerin).
  • Adjust doses in elderly and liver disease patients.

4. Excretion (Elimination)

Excretion is the process of removing drugs from the body, mainly through the kidneys.

Main Routes of Drug Excretion:

  1. Kidneys (Urine) – Most drugs eliminated this way.
  2. Liver (Bile/Feces) – Some drugs excreted in feces.
  3. Lungs (Exhalation) – Volatile drugs like anesthesia.
  4. Skin (Sweat, Saliva, Breast Milk) – Minor routes of excretion.

Factors Affecting Drug Excretion

FactorEffect on ExcretionExample
Kidney FunctionPoor kidney function slows drug excretion, leading to toxicity.Creatinine clearance tests kidney function.
pH of UrineAcidic or alkaline urine affects drug elimination.Aspirin overdose treated by alkalinizing urine.
Drug Half-LifeDetermines how long a drug stays in the body.Morphine half-life = 3 hours.
AgeInfants and elderly excrete drugs slower.Reduce renal-excreted drugs in elderly.

Drug Half-Life (t½):

  • Definition: Time required for half of the drug to be eliminated.
  • Example: If a drug’s half-life is 4 hours, after 4 hours 50% of the drug is gone.

🔴 Nursing Considerations:

  • Monitor kidney function (Creatinine, BUN) before giving drugs.
  • Adjust drug dose in renal failure patients.
  • Monitor half-life to determine dosing intervals.

Summary of Pharmacokinetics (ADME)

ProcessDefinitionMain OrganExample
AbsorptionDrug enters bloodstream.GI tract, Skin, LungsOral antibiotics take longer to act than IV antibiotics.
DistributionDrug moves to tissues.Blood CirculationSedatives act quickly in brain due to high blood flow.
MetabolismDrug is broken down.LiverParacetamol metabolized in liver; overdose causes liver damage.
ExcretionDrug is removed.Kidneys, LiverDiuretics excreted in urine.

Factors Influencing Medication Action:

Introduction

Systems of Measurement in Medication Administration:

Introduction

In healthcare, accurate measurement is critical for safe medication administration. Different systems of measurement are used to calculate and administer drugs, IV fluids, and other medical treatments. Nurses must be proficient in these systems to ensure precise dosing and prevent medication errors.


Definition of Systems of Measurement

A system of measurement refers to an organized method of quantifying substances using standardized units. In medication administration, different systems are used to measure drug weight, volume, and concentration.

Purpose of Measurement Systems in Nursing:

  • Ensures accurate medication dosing.
  • Prevents medication errors and overdose.
  • Provides standardized drug administration across healthcare settings.
  • Helps in calculating IV fluids, injections, and pediatric dosages.

Common Systems of Measurement Used in Nursing

There are three main systems of measurement used in medication administration:

SystemCommon UsesExample
Metric SystemStandard system in hospitals worldwide. Used for liquids, solids, and weights.Paracetamol 500 mg, IV fluid 1000 mL.
Household SystemUsed in home care and by patients for liquid medications.Cough syrup 1 teaspoon (tsp), Milk of Magnesia 1 tablespoon (tbsp).
Apothecary System (Old System – Rarely Used)Historically used for prescription writing. Now mostly replaced by the metric system.Codeine 2 grains (gr), Morphine ½ dram.

🔴 Nursing Considerations:

  • Use the metric system whenever possible for accuracy.
  • Avoid apothecary system usage due to risk of confusion.
  • Convert household measurements carefully for patient education.

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).

Example Calculation:

  • Order: Administer 250 mg of Amoxicillin.
  • Available Dose: 500 mg per 5 mL of suspension.

(250 mg500 mg)×5 mL=2.5 mL\left( \frac{250 \text{ mg}}{500 \text{ mg}} \right) \times 5 \text{ mL} = 2.5 \text{ mL}(500 mg250 mg​)×5 mL=2.5 mL

Answer: Administer 2.5 mL.


1. Tablet and Capsule Dosage Calculation

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​

Example Calculation:

  • Order: Give 75 mg of Aspirin.
  • Available Dose: 25 mg per tablet.

75 mg25 mg=3 tablets\frac{75 \text{ mg}}{25 \text{ mg}} = 3 \text{ tablets}25 mg75 mg​=3 tablets

Answer: Administer 3 tablets.

🔴 Nursing Considerations:

  • 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

Example Calculation:

  • Order: Give 150 mg of Acetaminophen.
  • Available Dose: 100 mg per 5 mL of syrup.

(150 mg100 mg)×5 mL=7.5 mL\left( \frac{150 \text{ mg}}{100 \text{ mg}} \right) \times 5 \text{ mL} = 7.5 \text{ mL}(100 mg150 mg​)×5 mL=7.5 mL

Answer: Administer 7.5 mL.

Oral Medication:

Introduction

Oral medication administration is the most common and convenient method of drug delivery. It involves the ingestion of medication through the gastrointestinal (GI) tract for systemic or localized effects.


Definition of Oral Medication

Oral medication refers to any drug that is administered by mouth and absorbed through the digestive system into the bloodstream. It includes tablets, capsules, liquids, powders, and syrups.

Key Features of Oral Medications:

  • Non-invasive and easy to administer.
  • Absorbed via the stomach or intestines.
  • Slow onset compared to injections but longer duration.

Action and Mechanism of Oral Medications

Oral medications work by being absorbed, distributed, metabolized, and excreted through various physiological processes.

1. Absorption (Entry into the Bloodstream)

  • Medications pass through the stomach or intestines into the bloodstream.
  • Factors affecting absorption:
    • Food intake (some drugs work best on an empty stomach, others need food).
    • Acidic or alkaline environment in the stomach.

2. Distribution (Transport to Target Site)

  • The drug travels through blood vessels to the site of action.
  • Protein binding affects drug availability.

3. Metabolism (Breakdown in the Liver)

  • The liver modifies the drug to enhance its effectiveness or prepare it for elimination.
  • Some drugs undergo first-pass metabolism, reducing their potency before entering circulation.

4. Excretion (Elimination from the Body)

  • Drugs are excreted via the kidneys (urine), liver (bile), or intestines (feces).
  • Kidney function affects drug elimination, especially in elderly patients.

🔴 Nursing Considerations:

  • Monitor for liver and kidney function in patients taking oral medications.
  • Educate patients about food and drug interactions that affect absorption.

Indications for Oral Medication

Oral medications are prescribed for various medical conditions.

Common Indications:

ConditionExamples of Oral Medications

Sublingual Route of Medication Administration.

Introduction

The sublingual route is a method of medication administration where drugs are placed under the tongue for rapid absorption through the mucous membranes. It provides faster onset of action compared to oral medications because it bypasses the digestive system and first-pass metabolism in the liver.


Definition of the Sublingual Route

The sublingual route refers to the administration of medication by placing it under the tongue, allowing it to dissolve and absorb directly into the systemic circulation via the sublingual mucosa.

Key Features of the Sublingual Route:

  • Faster absorption than oral medications.
  • Bypasses the gastrointestinal (GI) tract and liver metabolism.
  • Used for emergency and rapid-acting drugs.
  • Convenient and non-invasive.

Mechanism of Action & Absorption

Sublingual medications dissolve under the tongue and are absorbed directly into the bloodstream through the rich network of capillaries in the sublingual mucosa.

How Sublingual Absorption Works:

  1. Dissolution: The drug dissolves in saliva.
  2. Mucosal Absorption: The medication passes through the thin sublingual mucosa.
  3. Direct Entry into Circulation: The drug enters the systemic circulation via the capillary network.
  4. Rapid Onset: Medication reaches target organs quickly (within minutes).

🔴 Nursing Considerations:

  • Ensure the patient does not swallow the medication; swallowing reduces effectiveness.
  • Avoid giving water or food until the drug is completely absorbed.
