Front 1

Volume of Distribution

Back 1

Volume in which theamount of drug would need in order for it to be uniformly distributed toproduce the desired blood concentration in mg/ml.i

Front 2

Onset Of action

Back 2

The time (hr., min.,etc) at which the administered drug reaches the therapeutic range or it (drug)begins to produce the effect.

Front 3

Duration of Action

Back 3

The time span (hr.,min., etc), beginning the onset of action up to the termination of action.

Front 4

Termination of Action

Back 4

The time (hr., min.)at which the drug concentration in the plasma falls below the minimum effectiveconcentration (MEC).

Front 5

Therapeutic Range

Back 5

The plasmaor serum concentration (mcg/ml, ng/ml etc.) range, within which, the drug islikely to produce the therapeutic activity or effects.

Front 6

Latent heat of vaporization

Back 6

heat absorbed (incal/mol or calories/gram) when a liquid vaporizes at normal boiling point.

Front 7

Saturations Solubility Equilibrium

Back 7

the maximum amount (mgor g) of a solute that is present in solution form per unit volume of solventat constant temperature or pressure after attainment of equilibrium condition.

Front 8

Absorption

Back 8

a process by which theadministered dose of drug travels from the site of administration to the siteof measurement; exists in extravascular route; no absorption for intravascularroute because site of administration and site of measurement are the same.

Front 9

Heat of Solution

Back 9

is the heat absorbedor liberated when 1 mole of a solute is dissolved in a definite quantity of apure solvent, say 1000 grams of water, to yield a solution. Cal/mole

Front 10

Dissolution

Back 10

The process of powder particles dissolving inthe surrounding fluid to form a solution.

Front 11

Hygroscopicity

Back 11

Ability of a powder to adsorbmoisture from the atmosphere

Front 12

Deliquescence

Back 12

The amount of moisture adsorb is so high thatthe powder will dissolve and form a solution
