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.
