|

|
|

|
Ganirelix
|
|
Dopamine (DA) agonist (for Parkinson's disease), used also for hyperprolactinemia
|
Bromocriptine
|
|
Hormone inhibiting prolactin release
|
Dopamine
|
|
ACTH analog used for diagnosis of patients with corticosteroid abnormality
|
Cosyntropin
for an ACTHual diagnosis you must Co-Sign the form. |
|
Synthetic analog of ADH hormone used for diabetes insipidus and nocturnal enuresis
|
Desmopressin (DDAVP)
|
|
SE of OCPs
|
Increased thromboembolic events
|
|
Thyroid and anti-thyroid drugs
|
|
|
Most widely used thyroid drugs such as Synthroid and Levoxyl contain
|
L-thyroxine (T4)
|
|
T3 compound less widely used
|
Cytomel (liothyronine)
|
|
Anti-thyroid drugs (4)
|
Thioamides, iodides, radioactive iodine, and ipodate
|
|
Thioamide agents used in hyperthyroidism
|
Methimazole and propylthiouracil (PTU)
|
|
Thioamide less likely to cross placenta, inhibits peripheral conversion of T4 to T3 in high doses, and should be used with extreme caution in pregnancy
|
PTU
|
|
PTU (propylthiouracil) MOA
|
Inhibits thyroid hormone synthesis by blocking iodination of the tyrosine residues of thyroglobulin
|
|
Can be effective for short term therapy of thyroid storm, but after several weeks of therapy causes an exacerbation of hyperthyroidism
|
Iodide salts
|
|
Dose may need to be increased during pregnancy or with Ocs due to increased TBG in plasma
|
Thyroxine
|
|
Permanently cures thyrotoxicosis, patients will need thyroid replacement therapy thereafter. Contraindicated in pregnancy
|
Radioactive iodine
|
|
Radio contrast media that inhibits the conversion of T4 to T3
|
Ipodate
|
|
Block cardiac adverse effects of thyrotoxicosis such as tachycardia, inhibits the conversion of T4 to T3
|
Beta-blockers such as propranolol
|
|
Vitamins containing iron should NOT be taken simultaneously with levothyroxine because
|
Iron deiodinates thyroxine
|
|
Thyroxine dose may need to be increased in hypothyroid patient during pregnancy because
|
Estogens increase maternal TBG
|
|
Adrenocorticosteroid and adrenocortical antagonists
|
|
|
3 zones of adrenal cortex and their products
|
Glomerulosa (mineralocorticoids), fasciculata (glucocorticoid=GC), and reticularis (adrenal androgens)
|
|

|
Prednisone, methylprednisolone, prednisolone, and triamcinolone
|
|
Long acting glucocorticoids
|
Betamethasone and dexamethasone
|
|
Mineralocorticoids (2)
|
Fludrocortisone and deoxycorticosterone
|
|
Some side effects of corticosteroids (11)
|
Osteopenia, impaired wound healing, stria, thinning of skin,
increased appetite, PUD, HTN, edema, increased risk of infection, euphoria, psychosis |
|
Period of time of therapy after which GC therapy will need to be tapered
|
5-7 days
|
|
Inhibitors of corticosteroids biosynthesis
|
|
|
Used for Cushing's syndrome (increased corticosteroid)
|
Dexamethasone suppression test
|
|
Inhibits conversion of cholesterol to pregnenolone therefore inhibiting corticosteroid synthesis
