Up to 21 of Asians are ultra-rapid 2D6 metabolizers, leading to:
 
  1. A need to monitor drugs metabolized by 2D6 for toxicity
  2. Increased dosages needed of drugs metabolized by 2D6, such as the selective serotonin reuptake inhibitors
  3. Decreased conversion of codeine to morphine by CYP 2D6
  4. The need for lowered dosages of drugs, such as beta blockers

Question 2

Genetic polymorphisms account for differences in metabolism, including:
 
  1. Poor metabolizers, who lack a working enzyme
  2. Intermediate metabolizers, who have one working, wild-type allele and one mutant allele
  3. Extensive metabolizers, with two normally functioning alleles
  4. All of the above
