Four-Drug or Three-Drug Combo for H. Pylori
Researchers have reported that a four-drug regimen over 10 days has been found to work as well as the three-drug, seven-day regimen that's the standard ulcer treatment. In addition, it may help overcome the growing problem of antibiotic resistance.
Due to increased resistance to clarithromycin, the standard week-long therapy has become less effective in recent years. Resistance to metronidazole appeared to have no effect, and one of the effects of adding the bismuth salt is to help overcome resistance to metronidazole. Opinions show that bismuth-containing quadruple therapy is effective and acceptable "in regions where resistance to clarithromycin is high."

Lavender Oil Has Strong Antifungal Properties
Portuguese researchers have shown that lavender oil has strong antifungal properties, effectively destroying various dermatophytes and species of Candida when tested. In the last few years, there has been an increase in the incidence of fungal diseases, particularly among immunocompromised patients. Unfortunately, there is also increasing resistance to antifungal drugs.
The researchers suggest that the antifungicidal effect of lavender oil may be due to its ability to damage fungal cell membranes, eventually causing cell death. An active component, Lavandula oil, shows wide-spectrum antifungal activity and is highly potent, serving as a good starting point for developing this oil for clinical use to manage fungal infections. The results of this study are published in the Journal of Medical Microbiology.

House Panel Requests FDA Documents in Heparin Probe
U.S. health regulators have failed to identify those responsible for the widespread contamination of heparin; it is now three years after the Baxter drug was recalled, a U.S. House of Representatives panel said.
In a letter to the FDA, the House Energy and Commerce Committee called on the agency to release all documents related to its investigation into the drug and ingredients from China.
It is believed that all or some of the individuals responsible for the adulteration are still actively engaged in the Chinese pharmaceutical supply chain and pose a continuing threat to pharmaceutical products imported to the U.S.

Prescription Data Access to Be Decided by Supreme Court
Should physicians' prescription data be off-limits to drug companies? The court will decide whether Vermont can ban selling the information to drug companies. The importance in this case is what determines commercial speech. In one case, the law says companies can't sell prescription information for marketing purposes, and drug companies can't use it unless prescribing doctors consent.
IMS, a market research consulting company, argued that the law hindered its First Amendment rights. IMS was joined by PHARMA and others and sued Vermont Attorney General William Sorrell over the law's enforcement.
PHARMA companies use prescribing information to tailor marketing messages and influence doctors' prescribing practices; efforts often are directed toward increasing sales of brand drugs.

USP Details Proposed Changes to PET Drug Production Standards
The U.S. Pharmacopeial (USP) Convention has outlined a series of new quality-assurance standards for the production and compounding of PET drugs that would cover responsibilities such as personnel training, equipment maintenance, quality control, and labeling and packaging.
USP Chapter <823> Radiopharmaceuticals for Positron Emission Tomography-Compounding has not been modified since it was published in 1998 although there have been many changes through the evolution of the radiopharmaceutical over the past 13 years.
Public comment on the proposed changes will continue until March 31, 2011. If there are no significant changes to the revisions, USP could vote on a final draft in June. If major changes are necessary, USP will republish its proposal and again take public comment.
