4.2 Therapeutic Uses

Dyes

National Library of Medicine's Medical Subject Headings online file (MeSH, 1999)


TO DETERMINE CARDIAC OUTPUT, HEPATIC FUNCTION, & LIVER BLOOD FLOW. FOR HEPATIC FUNCTION STUDIES, CALCULATED AMT OF DIAGNOSTIC AGENT IS INJECTED INTO ARM VEIN. 20 MIN AFTER INJECTION, 6 ML OF VENOUS BLOOD IS WITHDRAWN FROM OPPOSITE ARM. AFTER COAGULATION & CENTRIFUGATION, CLEAR SERUM IS READ IN PHOTOMETER @ 800-810 NM.

Osol, A. and J.E. Hoover, et al. (eds.). Remington's Pharmaceutical Sciences. 15th ed. Easton, Pennsylvania: Mack Publishing Co., 1975., p. 1214


DYE RETENTION OF LESS THAN 4% IS FOUND IN HEALTHY SUBJECTS. ... FAILURE TO REMOVE DYE, AS INDICATED BY SERUM LEVELS IN EXCESS OF 4%, IS INDICATIVE OF IMPAIRED HEPATIC FUNCTION.

Osol, A. and J.E. Hoover, et al. (eds.). Remington's Pharmaceutical Sciences. 15th ed. Easton, Pennsylvania: Mack Publishing Co., 1975., p. 1214


USUAL, IV, BLOOD VOL DETERMINATION, 5 MG IN 1 ML; HEPATIC FUNCTION DETERMINATION, 0-5 MG/KG.

Osol, A. and J.E. Hoover, et al. (eds.). Remington's Pharmaceutical Sciences. 15th ed. Easton, Pennsylvania: Mack Publishing Co., 1975., p. 1214


DYE IS STABLE IN PLASMA & WHOLE BLOOD PERMITTING LATER ANALYSIS. USERS VARY BOTH CONCN & DOSAGE. IN MAN TOTAL DOSAGE HAS NORMALLY BEEN BELOW 2 MG/KG.

Rossoff, I.S. Handbook of Veterinary Drugs. New York: Springer Publishing Company, 1974., p. 275


4.3 Drug Warning

...CONTAINS SMALL AMT OF /5%/ SODIUM IODIDE; THUS, IT SHOULD BE USED WITH CAUTION IN PT ALLERGIC TO IODIDES & RADIOACTIVE IODINE UPTAKE STUDIES SHOULD NOT BE PERFORMED FOR AT LEAST 1 WK FOLLOWING ITS USE. SINCE PROBENECID HAS BEEN SHOWN IN DOGS TO AFFECT HEPATIC UPTAKE, THIS POSSIBILITY SHOULD BE KEPT IN MIND.

Osol, A. and J.E. Hoover, et al. (eds.). Remington's Pharmaceutical Sciences. 15th ed. Easton, Pennsylvania: Mack Publishing Co., 1975., p. 1214


SAFE USE OF THIS DRUG IN PREGNANCY HAS NOT BEEN ESTABLISHED.

5.3 Absorption, Distribution and Excretion

FOLLOWING IV INJECTION, INDOCYANINE GREEN IS RAPIDLY BOUND TO PLASMA PROTEIN, QUICKLY REMOVED FROM CIRCULATION BY LIVER, & EXCRETED IN BILE IN UNCONJUGATED FORM.

Osol, A. and J.E. Hoover, et al. (eds.). Remington's Pharmaceutical Sciences. 15th ed. Easton, Pennsylvania: Mack Publishing Co., 1975., p. 1214


WITH INDOCYANINE GREEN, IT HAS BEEN SHOWN THAT RAT HAS HIGHER MAX BILIARY EXCRETION RATE (0.065 MG/KG/MIN) THAN DOES RABBIT (0.05 MG/KG/MIN) OR DOG (0.027 MG/KG/MIN).

LaDu, B.N., H.G. Mandel, and E.L. Way. Fundamentals of Drug Metabolism and Disposition. Baltimore: Williams and Wilkins, 1971., p. 139


T/2 INCR WITH INCR DOSAGE. ... CONSIDERABLE DIFFERENCE HAS BEEN NOTED BETWEEN NORMAL MONGRELS & PUREBRED BEAGLES IN CLEARANCE TIMES.

Rossoff, I.S. Handbook of Veterinary Drugs. New York: Springer Publishing Company, 1974., p. 275


APPARENT HEPATIC EXTRACTION OF INDOCYANINE GREEN IN RATS WAS SURPRISINGLY LOW @ DOSES ABOVE 1 MG/KG. CHANGES IN HEPATIC BLOOD FLOW WOULD NOT ALTER CLEARANCE.

PMID:512932 IGA T, KLAASSEN CD; J PHARMACOL EXP THER 211 (3): 690 (1979)
