Sept. 23, 2010 -- The FDA will not ban Avandia -- but stringent restrictions will make it far harder for doctors to prescribe the safety-troubled diabetes drug.
The European Medicines Agency took harsher action. European sales of Avandia-containing drugs will be suspended over the next few months, although the agency did not formally withdraw approval.
The 600,000 U.S. patients currently taking Avandia can continue to take the drug only if their doctors officially attest that their patients understand the risks, that the drug is helping them, and that no other diabetes drug can keep their blood sugar under control.
New Avandia prescriptions can only be written for patients who, for medical reasons, cannot take Actos. Actos, a diabetes medication in the same class as Avandia, does not cause the heart problems linked to Avandia.
Isotretinoin in India: A tragedy in the offing Wednesday, March 28, 2007 08:00 IST Seema Thakral
Isotretinoin is the drug of choice for severe calcitrant cystic acne vulgaris, which often causes scarring and depression from disfigurement. Isotretinoin has been called "the greatest medical advance of the 1980's." A majority of patients with acne are permanently cleared after a four to five months course of treatment. It has also been used off-label for a variety of oncology uses including: cervical cancer, head and neck cancer, squamous cell cancer of the skin, juvenile chronic myelogenous leukemia (CML), and neuroblastoma. However, the drug is a proved teratogen and carries a significant risk of birth defects, if it taken during pregnancy. Birth defects, which have been documented following isotretinoin exposure include abnormalities of the face, eyes, ears, skull, central nervous system, cardiovascular system, and thymus and parathyroid glands. There is an increased risk …
 Various methods are used to obtain specimens for hematocritdetermination in neonates. We evaluated arterial sampling andfound this method to be acceptable. Arterial values correlatedclosely with simultaneously obtained venous samples. Venousblood obtained with a tourniquet had a significantly higherhematocrit than that obtained without a tourniquet. Influence of tourniquet application on venous blood sampling for serum chemistry, hematological parameters, leukocyte activation and erythrocyte mechanical propertiesBackground: Venous blood sampling is usually performed using a tourniquet to help locate and define peripheral veins to achieve successful and safe venipuncture. Despite widespread usage of tourniquets for venipuncture by medical and laboratory staff, very few are aware of the effects of tourniquet application on laboratory parameters. In addition, definitive guidelines regarding when and how to use a tourniquet for blood sampling are lacking. The aim of the present stu…
