An oral suspension contains 50 gr therapeutic agent in a pint of the suspension. Calculate the quantity of therapeutic agent in milligrams present in a teaspoonful dose.

Answer 1

I'll assume that gr is meant to mean grains and not grams which would be abbreviated as g.

Useful conversion factors:

1 g = 15.4 gr

1g = 1000 mg

1 tsp = 0.010 pint

50 gr / pint x 1 g / 15.4 gr x 1000 mg / g x 0.01 pint / 1 tsp = 32.5 mg/tsp
