Celebrex and Bextra Proving to be Popular Altenratives to Discontinued VioxxWritten by Elena Ivantsova
Montreal, Quebec (AffordableDrugs) December 30, 2004 – The prescription drugs Celebrex and Bextra have grown in popularity since arthritis painkiller Vioxx was pulled off market earlier this year for safety concerns. Celebrex and Bextra are similar drugs to Vioxx as they are cox-2 inhibitors, and they also help relieve pain caused by arthritic pain.Vioxx, arthritis medication produced by Merck Frost, was pulled off market earlier this year due to concerns about possible side effects. Certain reports indicated that extended use of Vioxx could lead to possibility of heart problems. At time Vioxx was removed it was among most popular and widely used medications. Last year, Vioxx generated annual sales of more than $2 billion. Since Vioxx was pulled, medications Celebrex and Bextra have become popular alternatives. Celebrex has seen its market share in cox-2 inhibitors increase substantially from 48.7% in September 2004 to 63.5% in October 2004. That is an increase of almost 15% in one month. Bextra has also seen a similar increase as it went from a 23.5% market share in September to a 36% in October. As can be seen from above data, void left by Vioxx is quickly being filled by Celebrex and Bextra.
| | Carbon Monoxide Levels - How Much is too Much?Written by Alexandria Haber
What is carbon monoxide?Carbon monoxide or CO is a colorless, odorless and tasteless gas. Due to this fact, it is very hard to detect presence of CO in your environment. It is, however, imperative that CO levels in your home are carefully monitored. Even at relatively low levels, CO is poisonous because it rapidly accumulates in blood thereby depleting its ability to carry oxygen. Extreme cases of CO poisoning result in death. Where does carbon monoxide come from? CO is a common by product of combustion of fossil fuels. When properly installed and maintained, most fuel burning equipment (natural gas, propane or oil) will produce insignificant amounts of CO. At what level does carbon monoxide become toxic? For healthy adults, CO becomes toxic when it reaches a level higher than 50 ppm (parts per million) with continuous exposure
