Shelf life is defined as the time necessary for the drug to decay to 90% of its original concentration

Shelf life is defined as the time necessary for the drug to decay to 50% of its original concentration

Shelf life is defined as the time necessary for the drug to decay to 10% of its original concentration

Shelf life is defined as the time necessary for the drug to decay to 100% of its original concentration

The proportion of a drug which introduced into the body and so is able to have an active effect

The concentration of the drug in the body will be half of the starting dose

The proportion of a drug which introduced into the body and so is able to have an inactive effect

The proportion of a drug which introduced into the body and so is able to have an partially active effect

· The maximum concentration recorded

· The minimum concentration recorded

· The shelf life of a drug

· None of the above

· The time take to reach Cmax.

· The time take to eliminate

· The time take to reach half life of a drug

· All of the above

· A measure of the exposure to the drug

· A graph plotted between Concentration and Time

· It describes the variation of a drug concentration in blood plasma as a function of time

· All are correct

· It determined by comparing the relative bioavailability of the research drug versus the generic drug

· It determined by comparing the relative bioavailability of the generic drug versus the generic drug

· It determined in healthy animals

· None is correct

· Absorption.

· Food Effect.

· Drug metabolism/ biotransformation

· All of the above are correct

· 80%-125%

· 85%-125%

· 80%-120%

· 90%-100%

Drug elimination is the removal of drugs from the body

Drug elimination is the absorption of drugs from the body

Drug elimination is the 50% eliminates of drugs from the body

Drug elimination is the metabolism of drugs from the body
