<prompt> A drug is more likely to cause toxicity in elderly patients due to all of the following reasons EXCEPT:decreased renal excretion of drugsdecreased hepatic metabolismincreased receptor sensitivitydecreased volume of distribution  <response>: Ans. is d ie decreased volume of distribution Volume of distribution is increased with aging. This leads to decreased elimination of the drug and hence increased toxicity.Other changes seen with aging which lead to increased toxicity of drugsincreased sensitivity of the target organsdecreased renal excretion of drugs decreased hepatic metabolism of drugsbody mass is decreased
