(arginine HCl)
R-Gene® 10 is indicated as an intravenous stimulant to the pituitary for the release of human growth hormone in patients where the measurement of pituitary reserve for HGH can be of diagnostic usefulness. It can be used as a diagnostic aid in such conditions as panhypopituitarism, pituitary dwarfism, chromophobe adenoma, postsurgical craniopharyngioma, hypophysectomy, pituitary trauma, acromegaly, gigantism and problems of growth and stature.
If the insulin hypoglycemia test has indicated a deficiency of pituitary reserve for HGH, a test with R-Gene® 10 is advisable to confirm the negative response. This can be done after a waiting period of one day. As patients may not respond to R-Gene® 10 (Arginine Hydrochloride Injection, USP) during the first test, the unresponsive patient should be tested again to confirm the negative result. A second test can be performed after a waiting period of one day. Some patients who respond to R-Gene® 10 do not respond to insulin and vice versa. The rate of false positive responses for R-Gene® 10 is approximately 32%, and the rate of false negatives is approximately 27%.
