New technology may prevent vitamin B12 deficient seniors and vegetarians from needing injectionsJune 18, 2008For those patients who receive the nearly 40 million intramuscular injections per year to treat their B12 deficiency, a new oral option may soon exist. According to the National Institutes of Health, vitamin B12 deficiency can lead to a wide spectrum of conditions, such as anemia, dementia and reduced cognitive functioning. Vitamin B12 deficiency is a significant health issue. Nearly 40 percent of the U.S. population is B12 deficient (Tufts University, Boston). This includes a sizable number of patients who are severely deficient and are currently being treated. Further, a vast number of people are completely unaware they are B12 deficient and will eventually need treatment. Seniors and strict vegetarians are most at risk. Symptoms such as fatigue, constipation, loss of appetite and weight loss can occur in those who are deficient. Currently, physicians rely on B12 shots for people with vitamin B12 deficiency because of the poor bioavailability of oral formulations. Past studies have shown that only approximately one percent of a vitamin B12 tablet gets absorbed in the bloodstream after traveling through the digestive track. Because so much of the vitamin is wasted, alternatives to effectively treat or protect against B12 deficiency are needed.
"Vitamin B12 is a perfect example of the successful application of our eligen® technology," said Cristina Castelli, Ph. D., AAPS expert and lead researcher at Emisphere Technologies, Inc. "Our current studies have shown our oral solid formulation brings vitamin B12 absorption to a range of 7-30% without the discomfort of an invasive route of administration." Ms. Castelli and other project researchers will be at the AAPS National Biotechnology Conference to present and discuss their research with hundreds of pharmaceutical scientists from countries around the world. Animal testing has been completed and researchers are now conducting human studies. American Association of Pharmaceutical Scientists | |||||||||||||||||||||

Related B12 Deficiency News Articles Vitamin B12 function may be diminished by excessive folate In a study of adults aged 20 and over, researchers at Tufts University showed that homocysteine and methylmalonic acid are at much higher levels in individuals who have a combination of vitamin B12 deficiency and high blood folate levels than in individuals who are also vitamin B12 deficient but have normal folate levels. Impact of elevated homocysteine levels on vision under study Homocysteine, an amino acid believed to contribute to heart attack, stroke and dementia, likely also is a player in retinal damage and vision loss, researchers say. Folate and B12 may influence cognition in seniors Folate and vitamin B12, two important nutrients for the development of healthy nerves and blood cells, may work together to protect cognitive function among seniors, reports a new epidemiological study from the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (USDA HNRCA). Fortifying food with folic acid benefits babies Adding folic acid to food can dramatically reduce the incidence of spina bifida and other birth defects. A study, published today in BMC Pregnancy and Childbirth, shows that the proportion of babies born with neural tube defects in the province of Newfoundland and Labrador dropped by 78% after the Canadian Government directed that folic acid must be added to flour, cornmeal and pasta. The study supports the continuation of this food fortification strategy. Detecting vitamin B12 deficiency prevents anaemia and memory loss Vitamin B12 is essential to human life. The body cannot make its own supplies and without an adequate dietary supply from animal sources or enriched cereals, up to 20 million people can suffer anaemia, risk nerve damage and even death. Unfortunately, vitamin B12 deficiency can go undetected for several years, remaining invisible to doctors while the likelihood of irreversible cell damage increases. Under EUREKA project E! 2263 HOLOTC, Norwegian diagnostics company Axis Shield teamed up with Danish academics to find a way to pick up early warning signs of potentially harmful B12 deficits. The project pioneered a unique B12 detection system, which tracks concentrations of holotc (short for ho LAUGHING GAS - A FASHIONABLE RECREATIONAL DRUG? (p 1347) Issue 19 April 2003 Embargoed 0001 h (London time) 18 April 2003 New Zealand authors of a research letter in this week's issue of THE LANCET report how laughing gas may be a popular recreational drug among young people. This could have implications for public health, as a case report in THE LANCET last year highlighted how excessive use of nitrous oxide ('laughing gas') caused spinal degeneration in a frequent user of the drug. In a questionnaire-based study, Richard Frith from Auckland Hospital, New Zealand, and colleagues surveyed 1782 students in their first year at the University of Auckland. Just under 60% of students who responded were aware of the use of nitrous oxide for recreation More B12 Deficiency News Articles |
