General Method for Preparation of solutions


Department of pharmaceutics and industrial pharmacy prelab 1 presented by osama saher

1)Ammonium chloride

Ammonium chloride 4 g[A.C., expectorant]

Liquid extract of liquorice5 ml [Mucolytic, expectorant]

Syrup 50 ml[Sweetening agent]

WaterQ.S to 100 ml[Vehicle (before to *)]

Fiat: Cough Syrup

Sig: 5 ml t.d.s.

Use: For Cough

This applies to all SOLUTIONS

Calculations

Volume of water (vehicle) = 100 - (5 + 50) = 45 ml

¾ Vehicle = ¾ * 45 = 33.75 ≈ 35 ml
