Arginine is considered a semi-essential amino acid because even though the body normally makes enough of it, supplementation is sometimes needed. For example, people with protein malnutrition, excessive ammonia production, excessive lysine intake, burns, infections, peritoneal dialysis, rapid growth, urea synthesis disorders, or sepsis may not have enough arginine. Symptoms of arginine deficiency include poor wound healing, hair loss, skin rash, constipation, and fatty liver.
Arginine changes into nitric oxide, which causes blood vessel relaxation (vasodilation). Early evidence suggests that arginine may help treat medical conditions that improve with vasodilation, such as chest pain, clogged arteries (called atherosclerosis), coronary artery disease, erectile dysfunction, heart failure, intermittent claudication/peripheral vascular disease, and blood vessel swelling that causes headaches (vascular headaches). Arginine also triggers the body to make protein and has been studied for wound healing, bodybuilding, enhancement of sperm production (spermatogenesis), and prevention of wasting in people with critical illnesses.
Arginine hydrochloride has a high chloride content and has been used to treat metabolic alkalosis. This use should be under the supervision of a qualified healthcare professional.
ARCA biopharma, Inc. today announced its planned next steps in response to the May 29, 2009 Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) for ARCA’s New Drug Application (NDA) seeking approval for GencaroTM (bucindolol hydrochloride) for the treatment of patients with chronic heart failure.

Gilead Sciences, Inc. today announced that aztreonam for inhalation solution, an investigational product for the treatment of infections due to Pseudomonas aeruginosa (P. aeruginosa) in patients with cystic fibrosis (CF), is scheduled to be reviewed by the Anti-Infective Drugs Advisory Committee of the U.S. Food and Drug Administration (FDA) on December 10, 2009.
MedImmune announced today that interim data from human studies of its nasal spray vaccine for the 2009 novel Influenza A (H1N1) virus demonstrate a similar clinical profile in children and adults 2 to 49 years of age as previously studied seasonal formulations of the vaccine.
AEterna Zentaris Inc., a global biopharmaceutical company focused on endocrine therapy and oncology, today announced that it has initiated activities intended to complete the clinical development of the growth hormone secretagogue (GHS) / ghrelin agonist compound macimorelin (AEZS-130) which could be the first oral diagnostic test approved for growth hormone deficiency (GHD). Macimorelin is the International Non-proprietary Name (INN) designated for the compound by the World Health Organization (WHO).
Arginetix, Inc. today announced it has closed a $10.75 million Series A financing. The company is developing small molecule inhibitors of the enzyme arginase for the treatment of endothelial dysfunction, including pulmonary arterial hypertension, atherosclerosis and asthma.
Gilead Sciences, Inc. announced today that the European Commission has granted conditional marketing authorization for Cayston® 75 mg powder and solvent for nebuliser solution (aztreonam lysine) for the suppressive therapy of chronic pulmonary infections due to Pseudomonas aeruginosa (P. aeruginosa) in patients with cystic fibrosis (CF) aged 18 years and older.
MedImmune announced today that the U.S. Department of Health and Human Services (HHS) has placed an order for an additional 29 million doses of its live attenuated influenza vaccine (LAIV) against the 2009 H1N1 influenza virus. This brings HHS orders to date to more than 40 million vaccine doses, with a total cumulative contract value of approximately $453 million.
Scientists at UC Santa Barbara have discovered a potential new drug delivery system. The finding is a biological mechanism for delivery of nanoparticles into tissue. The results are published in this week's Proceedings of the National Academy of Sciences.
MedImmune, Women's Professional Soccer (WPS) and the American Youth Soccer Organization (AYSO) today officially launched "Don't Play with the Flu,"((TM)) a national health awareness campaign that aims to highlight the importance of getting a seasonal influenza vaccination every year.
Elevated levels of the enzyme arginase contribute to vascular eye damage and Medical College of Georgia researchers say therapies to normalize its levels could halt progression of potentially blinding diseases such as diabetic retinopathy.
A new chemical imaging technique could one day help in the fight against atherosclerosis, suggests research published in the August 2009 edition of the Journal of the Royal Society Interface.
Recent genetic studies have revealed several new sites of genes that are risk factors for developing rheumatoid arthritis (RA).
Music is social communication between individuals - humming of lullabies attach infant to parent and singing or playing music adds croup cohesion. The neurobiology of music perception and production is likely to be related to the pathways affecting intrinsic attachment behavior, suggests a resent Finnish study. The study gives new information about genetic background of musical aptitude.
ARCA biopharma, Inc. has announced that a comparative analysis of primary endpoint data from four beta blocker trials was presented at the American College of Cardiology 58th Annual Scientific Session being held March 29-31, 2009.
Too little activity by gene regulators called PPARs appears to be a major player in the irreversible lung damage that can occur in children with heart defects, researchers say.
A Texas AgriLife Research scientist and fellow researchers have discovered that arginine, an amino acid, reduces fat mass in diet-induced obese rats and could help fight human obesity.
The National Association of County and City Health Officials (NACCHO) has announced a donation of up to one million doses of FluMist (Influenza Virus Vaccine Live, Intranasal) by MedImmune in a partnership aimed at increasing influenza awareness and vaccinations in underserved communities and populations.
