IODIDES MAY PPT THYROTOXICOSIS WHEN GIVEN TO PT WITH NODULAR GOITERS, OR IN EUTHYROID PT WITH AUTONOMOUS THYROID FUNCTION...DURING REMISSION OF HYPERTHYROIDISM FOLLOWING A COURSE OF THIONAMIDES... IN PT WITH CHRONIC THYROIDITIS, PREVIOUS RADIOIODINE THERAPY OR THYROIDECTOMY, IODIDES MAY INDUCE HYPOTHYROIDISM. /IODIDES/

4.4 Drug Indication

Indicated for use as a supplement to intravenous solutions given for total parenteral nutrition (TPN).


5 Pharmacology and Biochemistry
5.1 Absorption, Distribution and Excretion

Absorption

Iodide salts are readily absorbed in the gastrointestinal tract.


Route of Elimination

Iodides are expected to be renal excreted.


Volume of Distribution

Iodides are distributed widely throughout extracellular fluid of thyroid gland.


5.2 Mechanism of Action

RESPONSE TO IODIDE IN HYPERTHYROIDISM: /IN THYROID GLAND/...VASCULARITY IS REDUCED, GLAND BECOMES MUCH FIRMER & EVEN HARD TO THE TOUCH, CELLS BECOME SMALLER, COLLOID REACCUMULATES IN FOLLICLES, & QUANTITY OF BOUND IODINE INCREASES. /IODIDES/

HIGH CONCN OF IODIDE APPEAR TO INFLUENCE ALL IMPORTANT ASPECTS OF IODINE METABOLISM BY THE THYROID GLAND. CAPACITY OF IODIDE TO LIMIT ITS OWN TRANSPORT... ACUTE INHIBITION OF SYNTHESIS OF IODOTYROSINE & IODOTHYRONINE BY IODIDE IS ALSO WELL KNOWN (THE WOLFF-CHAIKOFF EFFECT)... /IODIDES/

THIS INHIBITION /WOLFF-CHAIKOFF EFFECT/ IS OBSERVED ONLY ABOVE CRITICAL CONCN OF IODIDE, & THE INTRACELLULAR...CONCN OF ANION APPEARS TO BE MAJOR DETERMINANT. WITH TIME THERE IS "ESCAPE" FOR THIS INHIBITION...ASSOCIATED WITH AN ADAPTIVE DECR IN IODIDE TRANSPORT & LOWERED INTRACELLULAR IODIDE CONCN. /IODIDES/

THE MOST IMPORTANT CLINICAL EFFECT OF HIGH IODIDE CONCN IS AN INHIBITION OF THE RELEASE OF THYROID HORMONE. THIS ACTION IS RAPID & EFFICACIOUS IN SEVERE THYROTOXICOSIS. THE EFFECT IS EXERTED DIRECTLY ON THE THYROID GLAND, & IT CAN BE DEMONSTRATED IN EUTHYROID SUBJECT & EXPTL ANIMALS AS WELL AS IN HYPERTHYROID PT. /IODIDES/

IODIDE ANTAGONIZES THE ABILITY OF BOTH THYROTROPIN & CYCLIC AMP TO STIMULATE ENDOCYTOSIS OF COLLOID, PROTEOLYSIS, & HORMONE SECRETION. /REPORTEDLY/... IODIDE ATTENUATES THE EFFECT OF TSH ON CYCLIC AMP IN VIVO & IN ISOLATED TISSUES. /IODIDES/
