    Study Notes

    Dosage Forms

    • Tablets, ointments, and injections are suitable for administration to patients.
    • Enteric-coated tablets dissolve in the small intestine.
    • Solutions are prepared by mixing the drug in water and can be used for oral, topical, or parenteral administration.
    • Ointments and creams are semi-solid dosage forms suitable for application to the skin and eyes.
    • Gelatin capsules dissolve in the stomach or small intestine.
    • Syrups are liquid dosage forms with a high concentration of sugar.
    • Suppositories are solid dosage forms inserted into the anal canal and dissolve at body temperature.

    Tablet Properties

    • Binding agents are used in tablets to hold the powder together.
    • Buccal tablets are designed to dissolve slowly in the mouth.
    • Enteric-coated tablets dissolve in the stomach or small intestine.

    Liquid Dosage Forms

    • Solutions involve mixing the drug in water and are suitable for oral, topical, or parenteral administration.
    • Injections are typically found in vials or ampoules.
    • Gels are liquid dosage forms that involve drug mixed with a gelatin-like viscous material.

    Semi-Solid Dosage Forms

    • Ointments are more occlusive and less absorbed into the skin compared to creams.
    • Creams are more hydrophilic and absorbed better into the skin compared to ointments.

    Pharmacodynamics

    • Pharmacodynamics focuses on the effects of drugs on the body.
    • The primary difference between pharmacokinetics and pharmacodynamics is that pharmacodynamics deals with the effects of drugs, while pharmacokinetics deals with the movement of drugs in the body.
    • A receptor is a specific binding site for a drug or ligand.
    • Agonists often bind to their target via weak, reversible bonds.
    • The clinical effect of a drug is primarily dependent on the drug's concentration at the site of action.
    • Inverse agonists decrease the normal physiological response.
    • G-protein coupled receptors have endogenous agonists.
    • The cAMP pathway involves the activation of effector adenylyl cyclase and subsequent formation of cAMP.
    • The G protein subtype associated with serotonin (5HT1) receptors is Gαi.
    • Direct ligand-gated ion channel receptors directly open or close an ion channel, leading to a rapid change in the ion flux across the membrane.
