Arginine Injection (Arginine Hydrochloride Injection) - Summary



Each 100 mL of R-Gene® 10 (10% Arginine Hydrochloride Injection, USP) for intravenous use contains 10 g of L-Arginine Hydrochloride, USP in Water for Injection, USP. L-arginine is a naturally occurring amino acid.

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 (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%.

Oral L-arginine supplementation in patients with mild arterial hypertension and its effect on plasma level of asymmetric dimethylarginine, L-citruline, L-arginine and antioxidant status. [2012]
CONCLUSIONS: L-arginine supplementation increases plasma arginine, citrulline and

Instant dentin hypersensitivity relief of a single topical application of an in-office desensitizing paste containing 8% arginine and calcium carbonate: A split-mouth, randomized-controlled study. [2012]
Abstract Objective. The aim of this study was to evaluate the clinical efficacy of an in-office desensitizing paste containing 8% arginine and calcium carbonate relative to calcium carbonate alone in the reduction of dentin hypersensitivity in a randomized, double-blind, split-mouth clinical trial...

Intravenous arginine and human skin graft donor site healing: a randomized controlled trial. [2011.05]
BACKGROUND AND AIMS: Studies evaluating the effect of arginine supplementation in human wound healing are inhomogeneous with conflicting results. This study aims to clarify the role of arginine supplementation in the healing of human skin graft donor sites... CONCLUSION: Intravenous arginine supplementation does not improve angiogenesis, reepithelialization or neutrophil influx in healing of human skin graft donor sites.

Phase II study of pegylated arginine deiminase for nonresectable and metastatic hepatocellular carcinoma. [2010.05.01]
PURPOSE: It is well known that hepatocellular carcinoma (HCC) is an arginine auxotroph due to argininosuccinate synthetase I deficiency. This study's purpose was to evaluate the effects of pegylated arginine deiminase (ADI) in terms of toxicity, tumor response, alpha-fetoprotein (AFP) levels, and serum arginine levels... CONCLUSION: Pegylated ADI is a promising drug that capitalizes on a significant enzymatic deficiency in HCC. It is safe, well tolerated, and may benefit patients with unresectable HCC.

L-arginine supplemented nondiluted blood cardioplegia: a clinical trial. [2010.04]
AIM: L-arginine was shown to improve protection of the myocardium during coronary artery bypass graft (CABG) surgery. The objective of the present study was to determine the concentration of L-arginine to obtain the most effective protection of the myocardium during CABG surgery... CONCLUSION: Nondiluted blood cardioplegic solution supplemented with 4 mmol/L of L-arginine was associated with a significant decrease of myocardial lactate release after aortic cross-clamping and reperfusion during CABG surgery.

Clinical Trials Related to Arginine Injection

Arginine Therapy for the Treatment of Pain in Children With Sickle Cell Disease [Enrolling by invitation]
The purpose of this study is to determine whether giving extra arginine to patients with sickle cell disease seeking treatment for vaso-occlusive painful events (VOE) will decrease pain scores, decrease need for pain medications or decrease length of hospital stay or emergency department visit.

Efficacy and Safety of L Arginine to Prevent Preeclampsia [Completed]
Randomized double-blind controled clinical trial to assess the efficacy and safety of L-arginine to prevent preeclampsia. applied to pregnant women with risk factors for preeclampsia. the main result was the development of preeclampsia as well as side effects to taking l arginine besides perinatal outcomes

Characterization of the Metabolic Fate of an Oral Arginine Form [Completed]
The purpose of this study is to compare the metabolic fate of two oral forms of L-Arginine in healthy subjects featuring metabolic syndrome related risk factors

Effects of L-arginine Supplementation in Adults With Moderate to Severe Asthma [Completed]
Nitric oxide is an important marker of airway inflammation in asthma. Nitric oxide may have a protective role in patients with moderate to severe asthma. The investigators believe that a natural amino acid, L-arginine, that augments nitric oxide levels can decrease asthma exacerbations and improve the asthma care of moderate to severe asthma patients. This study is a randomized, placebo controlled trial in which subjects will receive either 3 months of L-arginine supplementation or a placebo. The investigators will monitor subjects' symptoms, the number of asthma exacerbations, and lung function. In addition, we will draw blood, obtain induced sputum samples and measure exhaled breath nitric oxide levels at each monthly visit.

L-arginine and Vitamin D Adjunctive Therapy in Pulmonary Tuberculosis (TB) [Completed]
The purpose of this study is to determine whether adjunctive L-arginine and vitamin D can improve response to standard short course TB therapy in people with newly diagnosed pulmonary TB.
