Study Notes
Drug Classes and Effects
- Cushing's syndrome and osteoporosis can be induced by long-term use of glucocorticoids.
- Beta-blockers do not cause Cushing's syndrome or osteoporosis.
- NSAIDs do not cause Cushing's syndrome or osteoporosis.
- Antibiotics do not cause Cushing's syndrome or osteoporosis.
Drug Action and Terms
- A calcium channel blocker blocks the action of epinephrine.
- A beta agonist enhances epinephrine's effect.
- A alpha antagonist blocks the action of epinephrine.
- Cholinergic agonists mimic the actions of acetylcholine.
Drug Uses
- Mucolytics/expectorants treat wet coughs.
- Codeine and dextromethorphan can also treat coughs.
- Loratadine is not a treatment for wet cough.
Drug Properties
- Diphenhydramine, chlorpheniramine, and promethazine are sedative antihistamines.
- Cetirizine is a non-sedating antihistamine.
Hormonal Effects
- Prostaglandins are uterine stimulants.
- Oxytocin, causes uterine contractions, is also a uterine stimulant.
- Progesterone and estrogen are not uterine stimulants.
Enzyme Inhibitors
- Lipoxygenase inhibitors include montelukast, zileuton, aspirin and ibuprofen.
Receptor Activation
- Adrenaline activates both alpha and beta adrenergic receptors.
- Noradrenaline primarily activates alpha receptors.
- Isoproterenol and phenylephrine primarily activate beta receptors.
- Dobutamine primarily activates beta receptors.
Antagonist Types
- Histamine and cyproheptadine have a competitive antagonist relationship.
Mast Cell Stabilizer
- Cromolyn and fluticasone are mast cell stabilizers.
Asthma Treatment
- Salbutamol and Formoterol treat bronchial asthma.
- Beclomethasone and theophylline are also used in asthma treatment.

- Ranitidine and omeprazole are used to treat petic ulcers.
- Prostaglandins, ibuprofen, and aspirin are not used to treat ulcers.
Acetylcholine Blockers
- Atropine blocks the action of acetylcholine.
Adrenaline Receptor
- Adrenaline activates alpha and beta receptors.
Drug Half-Life
- Drug X has an 8-hour half-life.
