Gadolinium-based contrast agents, which are used mainly for magnetic resonance imaging and angiography, were first introduced partly because of the discovery in the 1990’s that iodine-based contrast agents could cause nephrotoxicity and acute renal failure. Some recent reports have suggested, however, that gadolinium-based agents may also be nephrotoxic.1 One patient who developed acute renal failure after use of gadolinium-based contrast had a renal biopsy that showed acute tubular injury.2Moreover, after exposure to gadolinium-based contrast, some patients with severe renal insufficiency,...

Inhaled drugs for asthma are available in the US mainly in pressurized metered-dose inhalers (MDIs), which require a propellant, and dry powder inhalers, which do not. The chlorofluorocarbon (CFC) propellants in MDIs are being replaced by hydrofluoroalkane (HFA) propellants for environmental reasons: CFCs contribute to the depletion of the ozone layer. December 31, 2008 will be the last day that albuterol MDIs using CFC propellants can be sold in the US. The FDA is expected to announce a termination date for other CFC-containing products in the near future.Three HFA albuterol inhalers and one...

When combined with formaldehyde, it forms melamine resin, which has a wide variety of industrial applications including the manufacturing of kitchenware,...
