theoretical principles of physicochemical science as
they applied to the practice of pharmacy

Biomedical aspects of the practice of pharmacy
Pharmaceutical Science
Pharmaceutical Science
_________ aspects of the practice of pharmacy
Biomedical
Entity that is administered to the patients so that they
receive an effective dose of a drug
Dosage Form
Any digit used to represent a magnitude or a quantity
in the place in which it stands
Significant figures
Significant figures RULES
○ Non-zero digits are always significant.
○ Zeros between non-zero are always significant.
○ Zeros at the beginning of a number are never
significant, special exception: with decimal point
○ Zeros that fall at the end of a number after a
decimal point are always significant
The measurable quantity, also derived from length
Volume
Volume Reference std is
CUBIC METER (cc or cm3)
Volume was originally defined in terms of_____
Liter
Mass Reference std is
Kg
is often expressed as the weight of a body
Mass
A push or pull required to set a body in motion
Force
The larger the mass of the body and the greater
the required _________, the greater the force
that one must exert
acceleration
Defined as the force per unit area
Pressure
Pressure unit commonly used in science is
dyne/cm
Is frequently defined as the condition of a
body that gives it the capacity to do work
Energy
Energy may be classified as
kinetic energy or
potential energy
Zero degree on the centigrade scale equals
______ on the Kelvin Scale
273.15°
This is a derived quantity since it combines the units of
mass and volume
Density
Density is a derived quantity since it combines the units of
mass and volume
Density is defined as the mass per unit volume at a fixed ____ and _____
temp
and pressure
Density is expressed in the cgs system in
grams per cubic centimeter (g/cm3)
The ratio of weight of a given substance to the weight
of an equal volume of a substance chosen as standard
Specific Gravity
It is a means of determining the strength, purity, or
volume of a substance
Specific Gravity
Errors that although sometimes unsuspected, may be
avoided or determined and corrected once they are
uncovered
Determinate (Constant)
The results of a series of tests will yield a random pattern
around an average or central value, known as the mean
Indeterminate (Accident or Chance)
Arise from random fluctuations in the temperature or other
external factors and from the variations involved in reading
instruments.
Pseudoaccidental or variable determinate errors
It can be corrected by careful analysis and refinement of
techniques
Pseudoaccidental or variable determinate errors
A measure of the agreement among the values in
a group of data
Precision
The agreement between the data and the true
value
Accuracy
Variability is expressed in
range, mean and standard
deviation
is expressed in range, mean and standard
deviation
Variability
the lowest and highest value
Range
the average deviation from the
mean
Standard deviation
more useful in
comparing variability
Coefficient of variation percent
unit of volume in the PH
mL
is the weight free from the influence of gravity
mass
other term for specific gravity
relative density
it measures the initial weight then with the object inside; should be at 25 degrees celsius
Pycnometer
use for alcohol content determination; cylindrical tube with a bulb
Hydrometer
Hydrometer types
Light and Heavy Hydrometer
force formula
mass x acceleration
Pressure units
mmHg and atm
heat dynamics or energy mechanism
Thermodynamics
total energy
enthalpy
random; measurement of energy
entropy
Colligative properties
Vapor Pressure Lowering
Osmotic Pressure
Boiling Point Elevation
Freezing Point Depression
degree of freedom
Gibb’s Phase Rule
