    Study Notes

    Pharmacokinetics vs. Pharmacodynamics

    • Pharmacokinetics describes how the body affects a drug.
    • Pharmacodynamics describes how a drug affects the body.

    Four Basic Pharmacokinetic Processes (ADME)

    • Absorption: Movement of drug from administration site to circulation.
    • Distribution: Movement of drug from circulation to different organs.
    • Metabolism: Breakdown of a drug within the body.
    • Excretion: Elimination of drug from the body.

    Drug Passage Across Membranes

    • Passive Diffusion: Movement along a concentration gradient, requires some lipid solubility.
    • Carrier-Mediated Processes: Involve transporters that facilitate or actively move drugs across membranes.
      • Solute Carrier Transporters (SLCs): Facilitate transport down a concentration gradient.
      • ATP Binding Cassette Transporters (ABCs): Require ATP to pump material against a concentration gradient.

    Routes of Administration

    • Enteral: Administration through the digestive tract. Examples: oral, rectal, sublingual.
    • Parenteral: Administration outside the digestive tract. Examples: intravenous, intramuscular, subcutaneous, intradermal, inhalation, transdermal.

    Factors Influencing Drug Absorption from the Gut

    • Drug Structure: Highly polar or ionized compounds are poorly absorbed.
    • Formulation: Capsules and tablets must disintegrate for absorption.
    • Gastric Emptying: Can affect the rate of absorption, but not the quantity absorbed.

    First-Pass Metabolism

    • Definition: Metabolism of a drug before it reaches systemic circulation.
    • Locations: Intestinal lumen, intestinal wall, and liver.
    • Consequences: Decreases the bioavailability of orally administered drugs.

    Advantages of Different Routes of Administration

    • Intravenous: 100% bioavailability, rapid onset, controlled release.
    • Sublingual: Escapes first-pass metabolism, rapid onset.
    • Intramuscular: Good bioavailability, controlled release.
    • Transdermal: Controlled release, localized effects.
    • Inhalation: Rapid onset, localized effects, can avoid first-pass metabolism.

    Bioavailability

    • Definition: The fraction of a drug dose that reaches systemic circulation.
    • Calculated as: AUC (oral) / AUC (IV) x 100
    • Importance: Determines the dose required for different routes of administration.

    Drug Plasma Concentration vs. Time Plots

    • Oral Administration: Shows the time to reach peak plasma concentration (Cmax) and time at or above the minimum effective concentration (MEC).
    • IV Administration: Shows a rapid rise in plasma concentration, since the drug bypasses first-pass metabolism.

    Pharmacokinetics and Pharmacodynamics

    • Pharmacokinetics is the effect of the body on a drug. It describes the movement of drugs into, around, and out of the body.
    • Pharmacodynamics is the effect of a drug on the body. It describes the physiological and biochemical effects alongside the drug's interactions with 'targets'.

    Four Key Processes Involved in Pharmacokinetics

    • Absorption: Transfer of a drug from the site of administration into the general circulation. Bioavailability is the proportion of a drug that enters the bloodstream after administration.
    • Distribution: The transfer of a drug from the general circulation into different organs of the body.
    • Metabolism: The breakdown of a drug from its original form.
    • Excretion: Removal of a drug from the body.

    Routes of Drug Administration

    • There are three main categories of drug administration: topical, enteral, and parenteral.
    • Topical administration applies directly to the area where it is needed. Examples include skin creams, eye drops, and nasal sprays.
    • Enteral administration involves giving medication through the digestive tract. Examples include oral, sublingual, and rectal routes.
    • Parenteral administration refers to any route other than the digestive tract. Examples include inhalation, injection (IV, IM, SC, and ID injections).
    • Oral administration (by mouth) is the most common and convenient.
    • Sublingual administration (under the tongue) bypasses the first pass metabolism.
    • Rectal administration can be used for localized or systemic effects.
    • Intravenous (IV) administration is directly into a vein.
    • Intramuscular (IM) injection is given into large muscle masses.
    • Subcutaneous (SC/SQ) injection is given below the dermis, allowing for slow and prolonged effects.
    • Intradermal (ID) injection is given into the dermis, used for allergy testing and local anesthesia.

    Drug Absorption

    • Drug passage across the membranes is important for absorption, distribution, and excretion.
    • Lipid bilayer: drugs can diffuse through pores or ion channels, pass through the lipid bilayer itself, or be transported by carrier molecules.
    • Passive diffusion: Movement of drugs across membranes from high concentration to low concentration.
    • Carrier-mediated transport includes solute carrier transporters (SLCs) which facilitate the transport of drugs down the concentration gradient, and ATP binding cassette transporters (ABCs) which require ATP to pump material.
    • P-glycoproteins are a type of ABC transporter which contributes to multidrug resistance.

    First Pass Metabolism

    • **Drug is metabolized in the liver before reaching systemic circulation **after oral administration. Only a proportion of the drug reaches the circulation.
    • Alternative routes of administration such as intravenous, intramuscular, and sublingual avoid this effect.

    Bioavailability (F)

    • The fraction of the administered dose that reaches the systemic circulation as intact drug.
    • Determined by comparing plasma levels after different routes of administration to plasma levels after intravenous administration.
    • Bioavailability is the fraction of drug reaching systemic circulation as the parent drug.
    • Bioavailability can be expressed as a decimal (0.25) or a percentage (25%).
    • IV administration has a bioavailability of 100%. Non-IV routes range from 0-100%.

    Area Under The Curve (AUC)

    • A measure of the total amount of drug that enters the body after administration.
    • Calculated from a plasma concentration-time curve.
    • Units are concentration × time (e.g., mg.hr L−1).
    • The AUC is higher with IV administration than with oral doses.

    Drug Plasma Concentration vs Time Plots

    • Typical plasma level curve after IV administration: Maximum plasma concentration occurs at time = 0, immediately after dosing.
    • Typical plasma level curve after oral administration: maximum plasma concentration (Cmax) is reached at a time tmax after administration.

    Plasma Concentration - Time Curve After Oral Administration

    • Onset of action occurs when plasma levels reach the minimum effective concentration (MEC).
    • Duration of action is the time period the plasma level remains at or above the MEC.
    • Maximum safe concentration (MSC) is the point above which adverse effects occur and the concentration should remain below to minimize adverse reactions.

    Pharmacokinetics vs. Pharmacodynamics

    • Pharmacokinetics: The study of how the body affects a drug.
    • Pharmacodynamics: The study of how a drug affects the body.

    Four Key Processes of Pharmacokinetics

    • Absorption: How a drug enters the bloodstream.
    • Distribution: How the drug moves around the body.
    • Metabolism: How the drug is broken down by the body.
    • Elimination: How the body gets rid of the drug.

    Routes of Administration

    • Topical: Applied directly to the skin, eyes, nose, or other areas for a local effect.
    • Enteral: Given through the digestive tract (e.g., swallowed).
    • Parenteral: Given by routes other than the digestive tract (e.g., injection, inhalation).

    Factors Affecting Absorption from the Gut

    • Drug structure: Highly polar or ionized drugs are poorly absorbed.
    • Formulation: Capsules and tablets must disintegrate for absorption.
    • Gastric emptying: Food slows down absorption by delaying gastric emptying.

    First-Pass Metabolism

    • Drugs absorbed from the gut first pass through the liver before entering systemic circulation.
    • The liver can metabolize some drugs, reducing the amount that reaches the bloodstream.
    • This can be avoided by giving drugs intravenously, sublingually, or rectally.

    Bioavailability

    • The proportion of an administered drug dose that reaches the systemic circulation in its active form.
    • Measured as a percentage or a decimal.
    • Bioavailability determines the required dose for different routes of administration.

    Bioavailability and First-Pass Metabolism

    • Intravenous administration: 100% bioavailability (no first-pass metabolism).
    • Oral administration: Bioavailability can vary due to first-pass metabolism, ranging from 0 to 100%.

    Importance of Bioavailability

    • The true dose is not the amount swallowed, but the drug available to exert its effects.
    • Understanding bioavailability is essential for prescribing the correct dose for different drug formulations and administration routes.
