alter one or more of the pharmacokinetic parameters of a drug including oral bioavailability‚ volume of distribution‚ drug binding to plasma proteins‚ and most importantly the rates of metabolism and excretion‚ i.e.‚ drug clearance.. To minimize drug toxicity and maximize therapeutic benefits‚ it is often necessary to adjust drug dosage in proportion to the degree of renal insufficiency. A drug will most likely require dose adjustment in renal disease if: 1. A substantial fraction (> 40%) of the

Having been reported by the Environmental Protection Agency (EPA) as low in toxicity at safe levels‚ few studies have looked at the effect of these many inert ingredients in roundup.

poisoned by hydrogen selenide and selenium. Increasing industrial applications of selenium and the fact that workers may be exposed to Hydrogen Selenide have led authors to make a further investigation of the toxicity of this substance. The purpose of this investigation was to determine the toxicity of this substance (Dudley). Hydrogen Selenide is an inorganic compound with the formula of H2Se. It’s the simplest ( and virtually the only) hydride of selenium. H2Se is a colorless‚ flammable gas under standard

agent because it not only causes tissue injury but also can be absorbed systemically and cause neurologic toxicity. Deaths have occurred with the use of podophyllin on exuberant perianal warts; the surface area of the lesions increases the absorption of the drug. Podophyllin is contraindicated in pregnancy. The authors prefer podofilox to podophyllin because podofilox results in less toxicity and can be self-administered by the

That killer--naturally occurring arsenic in the water drawn from family wells--appears to have been released through a process involving crop irrigation‚ at least in one part of the country. At a research site in the southern part of Bangladesh‚ scientists calculated that irrigation pumping‚ which began in the last several decades‚ has

What I didn’t know was that over-hydration results in complications called water toxicity. Water toxicity occurs when the body experiences a loss of water and minerals while sweating which causes a dilution of sodium in the body. Symptoms that occur are similar to that of dehydration which includes nausea‚ muscle cramps‚ disorientation and slurred

Hundreds of animals die every day due to the fact that people pour so much chemicals onto their skin to test toxicity levels. Animals cannot talk and that is why people need to be their voices. Consumers have the power to stop animal testing by not buying animal tested products. Experimentation on animals is unnecessary and cruel. Even though there are some animals
