FDA OKs New Drug for Overactive Bladder

The U.S. Food and Drug Administration on Friday approved a new drug to help people who struggle with an overactive bladder.

The drug, Toviaz (fesoterodine fumarate), made by German manufacturer Schwarz Pharma, works by relaxing the smooth muscle tissue of the bladder, reducing frequent urination, the urge to urinate, and sudden urinary incontinence, the Associated Press reported.

"Patients who suffer from overactive bladder face quality of life issues that can hamper their ability to enjoy life to its fullest," Dr. George Benson, deputy director of the FDA's Division of Reproductive and Urologic Products, said in a news release. "This new drug will provide an additional treatment option to help them manage problems with an overactive bladder."

Toviaz, to be taken once a day by adults only, will be available by prescription only.

The FDA said it approved Toviaz based on the results of two studies involving more than 1,000 people with the disorder. Common side effects were dry mouth and constipation; less frequently reported side effects were dry eyes and trouble emptying the bladder, the AP said.


Consumer Group Questions Safety of Nanoparticles in Sunscreens

Four out of five mineral-based sunscreens that claim not to contain nanoparticles actually do contain them, says a report released Friday by Consumers Union, publisher of Consumer Reports.

The organization urged the U.S. Food and Drug Administration to conduct a full-scale safety review of nanoparticles in sunscreens.

"The widespread use of nanoparticles of titanium dioxide and zinc oxide in sunscreen is involving consumers in a vast experiment as to the safety of these products," Michael Hansen, a senior scientist at Consumers Union, said in a news release.

"These very tiny nano-sized particles are known to have different properties than the conventional versions of these chemicals and could be harmful to health. The FDA should require safety data for all these nanoparticles, and at the very least, they should require companies to be truthful about whether or not they are using nano-ingredients," Hansen said.

According to Consumers Union, the four sunscreens that claimed not to contain nanoparticles, but did contain them, were: Aubrey Organics Natural Sun SPF 25 Green Tea Protective Sunscreen; Badger SPF 30 Sunscreen; Kiss My Face SPF 30+ Sun Screen with oat protein complex; and Mexitan SPF 30 Sunscreen. Zinka Colored Nosecoat was the only one of the five that contained no nanoparticles, the group said.


China Widens Melamine Investigation

The investigation into melamine-contaminated food in China is being widened, Chinese officials said Friday as there was more evidence that the toxic industrial chemical is widespread in the nation's animal feed supplies.

Earlier this week, food safety tests showed the eggs produced in three different provinces were contaminated with melamine, which has been blamed for causing kidney stones and renal failure in infants who consumed milk products tainted with the chemical. The egg test results triggered recalls and consumer warnings, The New York Times reported.

Hong Kong officials announced earlier this week that a wide variety of Chinese-produced foods -- including vegetables, flour and meat products -- would be tested for melamine.

The reports of contaminated Chinese foods are causing concern worldwide, the Times reported.

Also Friday, BBC News reported that the addition of melamine to animal feed in China is likely routine and an "open secret," according to reports published in several state newspapers.

As a whole, the animal feed industry in China seems to have decided to use melamine to reduce production costs while maintaining the protein count for quality inspections, said an editorial in the state-run China Daily.
