Hormone Drugs Flashcards
Omnitrope
Recombinant human growth hormone
Nutropin
Recombinant human growth hormone
Norditropin
Recombinant human growth hormone
Genotropin
Recombinant human growth hormone
Siazen
Recombinant human growth hormone
Mecasermin
Recombinant IGF-1 which is a growth hormone (produced by liver) which causes bone growth in children at the epiphyseal plate.
Dopamine
along with somatostatin leads to decreased GNRH and prolactin release.
Bromocriptine
dopamine agonist leading to decreased growth hormone production.
Prolactin
Generated in the Anterior pituitary, causes milk let down, has no negative feedback
Oxytocin
Posterior pituitary, causes milk ejection
Thyroid hormone
Only peptide hormone to have an intracellular receptor
Levothyroxine
T4 drug replacement
Negative regulators of Thyroid hormone
Dopamine, somatostatin
Thyroid peroxidase
responsible for combining mono and di iodothyronine to make T3 and T4. T3 is more active than T4, T4 converted to T3 intracellularly by deiodinase
Thyroid binding globulin
Thyroid hormone carrier protein binds both T3 and T4, binds more hormone than albumin
Prophylthiouracil
Targets deiodinase 1 preventing activation of T4 to T3
thyrotoxicosis
due to thyroid storm and excessive thyroid hormone in circulation. Treat with beta blocker, thioamides (antithyroid), corticosteroid.
Liothyronine
T3 drug supplement
Methimazole
Thioamide used to treat hyperthyroidism by inhibiting thyro-peroxidase preventing conversion of T4 to T3
Carbimazole
Thioamide used to treat hyperthyroidism by inhibiting thyro-peroxidase preventing conversion of T4 to T3
11-B-hydroxylase
responsible for the conversion of steroids to their active form
Testing for hypercortisolism
dexamethasone challenge test. If ACTH drops, it is a primary adenoma, if ACTH with high dose still doesn’t drop, it is likely an ectopic ACTH tumor
Cortisol
Active form of cortisone
Hydrocortisone
Synthetic cortisone
Prednisone
glucocorticoid
Methylprednisone
more potent glucocorticoid
Dexamethasone
Incredibly potent glucocorticoid with no mineralocorticoid effect
Fludrocortisone
Incredibly strong mineralocorticoid, and strong glucocorticoid
Ketoconazole
Inhibits side chain cleavage (rate limiting step of steroid synthesis) antifungal. prevents glucocorticoid and androgen synthesis.
Metyrapone
Inhibits 11 Beta hydroxylase preventing activation of steroids
