ppar Flashcards
Area of pharmacy that dealt with the quantitative and theoretical principles of physicochemical science as they applied to the practice of pharmacy
Physical Pharmacy
Biomedical aspects of the practice of pharmacy
Pharmaceutical Science
Entity that is administered to the patients so that they receive an effective dose of a drug.
Dosage Form
Problem Solving that uses the fact that any number or expression can be multiplied by 1 without changing its value.
Dimensional Analysis
Also known as factor-label method or unti factor.
Dimensional Analysis
Ratio of like dimensioned quantites.
Conversion Factor
The goal is every unit that is not necessary will be cancelled out and all the units needed will not be cancelled out.
Conversion Factor
Is a measure of the agreement among the values in a group of data.
Precision
Is the agreement between the data and the true value.
Accuracy
The measurable quantity, also derived from length.
Volume
Reference standard is CUBIC METER; its cgs unit is one millionth of this value or 1 cubic centimeter (cc or cm3).
Volume
This was originally defined in terms of liter, the volume of kilogram water at 1 atm and 4°C
Volume
Reference standard is kg
Mass
This is the mass of a platinum-iridium block preserved at the Bureau of Weights and Measures
Mass
Often expressed as the weight of a body
Mass
Energy is frequently defined as the condition of a body that gives it the capacity to do work
Work and Energy
Energy may be classified as kinetic energy or potential energy
Work and Energy
Zero degree on the centigrade scale equals 273.15° on the Kelvin Scale
Temperature
This is a derived quantity since it combines the units of mass and volume.
Density
Defined as the mass per unit volume at a fixed temp and pressure and is expressed in the cgs system in grams per cubic centimeter (g/cm3)
Density
In SI units, it is expressed as as kilograms per cubic meter.
Density
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
Water is the chosen substance as the standard for solids and liquids. It is known that water has a unit weight of 1 gram per milliliter of space occupied.
Specific Gravity
errors sometimes unsuspected but maybe avoided or determined and corrected once they are uncovered.
Determinate or constant errors
occurs by accident or chance.
Indeterminate Errors
arise from random fluctuations in the temperature or other external factors and from the variations involved in reading instruments. It can be corrected by careful analysis and refinement of techniques.
Pseudoaccidental or variable determinate errors
Variability is expressed in range, mean, and standard deviation.
MEASURES OF DISPERSION
is the highest and the lowest value.
Range
the average deviation of the mean (x).
Standard Deviation
more useful in comparing variability.
Coefficient of variation percent
A push or pull required to set a body in motion
Force
The larger the mass of the body and the greater the required acceleration, the greater the force that one must exert
Force
Defined as the force per unit area; the unit commonly used in science is dyne/cm.
Pressure
