Measuring

Measuring Cup

(Cup Measure)

For adjustment of final volume only *

Graduated Cylinder

(Cylindrical measure)

slide3
Prescriptions are best written in latin language, WHY?

1) It is language of medical science all-over the world.

2) Latin names are definite with no mis-interpretation

3) unknown by patients thus prevent worry and fear

slide4
Simple Solutions
  • They are liquid dosage forms prepared by dissolving soluble substances in an aqueous or non aqueous vehicle.
  • Water soluble substances may be either:
slide7
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

slide9

Stirring

Filter on cotton wetted with water *

If turbid, filter

*Not dripping water

*Never filter a colored solution so filter before the coloring agent addition

2) Ferrous Fumarate

Ferrous Fumarate5 g [A.C., antianeamic]

Tr. of nux-vomica 3 ml[Bitter stomachic]

Syrup 10 ml[Sweetening agent]

Water to 90 ml[Vehicle]

Fiat : Mist.

Sig.: 15 ml P.C.

Calculations

Volume of water (vehicle) = 90 - (10 + 3) = 77 ml

¾ Vehicle = ¾ x 77 = 57.5 ≈ 60 ml

Precautions

Sprinkle ferrous fumarate at the center of the vehicle to prevent the formation of sticky mass which is difficult to be dissolved.

No filtration. …why??? (A: colored solution)

3) Phenobarbital elixir
  • ℞ Elixir: It is clear flavored, sweetened hydroalcoholic solution intended for oral use.

Phenobarbital 0.4 gm (0.2 g)(A.C. tranquilizer)

Rules of ROMAN numbers:

1) When the left letter is ≥ 1st letter  (+) SUM

slide24
I, X and C are called SUBTRACTORS

i.e. can be subtracted only from the next higher two values

i : can be subtracted only from V and X

X: can be subtracted only from L and C

C: can be subtracted only from D and M

Example:

= xLix not iL

95 = XCV not vC

99 =Xcix not iC

i

X

L

C

D

M

V

slide26
2) Write the following in arabic numbers
  • X
  • L-X=40
  • V>I
  • 5+1+1+1=8
  • 40+8=48

Hundreds

units

Tens

Thousands

  • C
  • M-C=
  • 1000-100 =900
  • LXXX=
  • 50+10+10+10=80
  • I
  • V-I=
  • 5-1=4
  • M=1000
slide27
Practical Problems

1) Write the following in roman numbers

  • 10+8
  • 8+10
  • 10=X
  • 8=5+3
  • 8=V+ III
  • XVIII
slide28
Practical Problems

1) Write the following in roman numbers

  • 1000=M
  • 1000+900+80+4
  • 900=1000-100
  • =CM
  • 80=50+10+10+10
  • 80=100-20
  • 4=5-1
  • =iv
  • 80=LXXX
