Calcitriol is the active form of Vitamin D = 1,25-(OH)2D3;
Choecalciferaol (Vitamin D3) synthesized in the skin and transported to the blood, binds to specific receptors in perhipheral cells → first OH added in the liver (25-OH-D3);
In the kidney, 25-OH-D3 can be converted to either the active form Calcitriol (1,25) or the inactive form (24,25); The diols are converted to 1,24,25 for excretion;
↑ plasma Ca by...

Definition
Myositis: Muscle symptoms with high CPK elevations.
Rhabdomyolysis: Muscle symptoms, marked CPK elevations, dark colored urine (myogobinuria) and acute renal failure*
Caused by statin inhibition of cholesterol synthesis in the muscles.
Risk factors include: advanced age (>75 years), renal or hepatic dz, diabeteis, high doses of statins.
Made worse by taking statins with Gemfibrozil. |

2) Oral Azole Antifungals,
3) Selected SSRIs (nefazodone),
4) CCBs (verapamil and diltizem > DHPs),
5) Grapefruit juice,
6) HIV Protease inhbitors,
7) Selected Immunosuppressants (Cyclosporine*) |

|
Term
|
Definition
Key because it inhbitis pathways involved in statin metabolism*
CI with simvastatin and dose reductions are required with Pravastatin.
Also increases the occurence of rhabdomyositis with other statins,
Increases the risk of gallstone formation when admin with Ezetimibe.
Class C in pregnancy. |

Definition
Synthroid - L-T4;
Thyroid replacement therapy for hypothyroid pt;
High doses required in children;
Takes several weeks for a steady state to be reached, monitor levels to acheive max control. |
|
|
Term
|
Definition
Mixture of T3 and T4 from desiccated animal thyroid preparations;
Used in thyroid replacement therapy;
Animal preparations are less desirable as they are often unpredictable. |
|
|
Term
|
Definition
(PTU) - Antithyroid drug;
Inhbitis iodine organification (iodination and coupling in teh thyroid) and also inhibits peripheral conversion of T4 to the more active T3 form by deiodinases;
Readily abosrbed, shorter t1/2 than methimazole;
Prefered drug in pregnancy (less placental transfer, ltd excretion in milk);
SE: minimal, rash, agranulocytosis |
|
|
Term
|
Definition
Antithyroid Drug;
10x more potent than PTU;
Inhbitis iodine organification (peroxidase catalyzed reactions of iodination and couping);
Avoid in pregnancy (crosses the placenta and becomes concentrated in the fetal thyroid). |
|
|
Term
|
Definition
Radioactive Iodine;
Oral admin;
Concentrates in the thyroid gland where it emits beta-radiation which destroys part or all of the thyroid parenchyma;
Used to tx hyperthyroidism in pt who are 35 years or older (not used in women of childbearing age);
No evidence has been found of radiation damage to other tissues. |
|
|
Term
|
Definition
Contrast agent;
Used in treatemetn of hyperthyroidism (off-label) as they inhbit conversion of T4 to T3 peripherally. |
|
|
Term
Describe the Calcium Sensing Receptor |
|
Definition
G Protein-Coupled Receptor;
Found in the parathyroid glands as well as in the C-cells of the thyroid. Is also expressed in the kidney, on osteoblasts, some cells of the GI, and in some hematopoietic cells;
Activation of the GPCR → Phospholipase C activation → generation of IP3 and DAG → inhibition of cAMP |
|
|
Term
|
Definition
Synthesized as a preprohormone by the parafollicular/C -cells of the Thyroid gland;
Act on Osteoclasts and osteoblasts by binding to a membrane receptor;
Binding to membrane receptors on osteoclasts → ↓ ruffled border SA on clasts*
Note that Calcitonin, though it generally opposes the effects of PTH, is not a global inhbitor of PTH* |
|
|
Term
|
Definition
GnRH antagonist;
↓ release of FSH and LH from the AP;
Tx: some hormone-sensitive cancer, uterine conditions (fibrosis, endometriosis), and in IVF;
CI: Renal Failure or in women 65 or older |
|
|
Term
|
Definition
GnRH antagonist;
Blocks the release of FSH/LH from the AP;
Used in fertility clinics to control ovulation |
|
|
Term
|
Definition
GnRH agonist;
Promotes release of FSH and LH from the AP;
Non-pulsitile/constant stimulation of FSH/LH suppresses the release of sex hormones;
Tx: prostate and breast cancers, also in benign disorders of the endometrium, assissted reproduction and precocious puberty;
SE: Bone pain, GI upset, decreased erections/libido, memory loss. |
|
|
Term
|
Definition
GnRH agonist;
Promotes release of FSH and LH from the AP;
Non-pulsitile/constant stimulation of FSH/LH suppresses the release of sex hormones;
Tx: prostate and breast cancers, also in benign disorders of the endometrium, assissted reproduction and precocious puberty;
Shows an initial surge of Testosterone followed by reduced levels of T. |
|
|
Term
|
Definition
GnRH analog;
Constant stimulation of FSH/LH reduces sex hormone release;
Daily IM injection or long-lasting SubQ implant;
Tx: Prostate cancer, uterine fibroids and precocious puberty; |
|
|
Term
|
Definition
GnRH agonist;
Constant stimulation of gonadotropes of the AP leads to desensitization and decreased sex hormone release;
Tx: endometriosis, uterine fibroids, in IVF and precocious puberty;
SE: (due to reduced estrogen levels) hot flashes, vaginal dryness, decreased libido, HA |
|
|
Term
|
Definition
Thyrotropin-releasing hormone;
