COURSE CODE: BPH 2101
COURSE CREDIT UNIT: 4
ACADEMIC PROGRAMME: Pharmacy, B.Sc
COLLEGE/SCHOOL/FACULTY: School of Pharmacy
STATUS: Core
PROGRAMME TYPE: Undergraduate

Course Description

This course covers fundamental concepts in pharmaceutical calculations, using specific gravity to weigh and measure volumes of solvents and solutions, weights and measures, various ways of expressing concentration of active drug substances in drug formulations, calculation doses for adult and pediatric patients, preparation of isotonic solutions, active drug moiety as well as reducing and enlarging drug formulas.

COURSE JUSTIFICATION

As one of the most trusted professionals, pharmacists are expected to dispense medications accurately to ensure the safety and wellbeing of patients. Pharmacists perform calculations that involve measurements, fractions, decimals, conversions and ratios. This course combines mathematical formulas with chemical equations to create content that is vital to a pharmacist's role and job responsibilities. 

COURSE AIM

To introduce mathematical concepts and methods needed for the later professional work of the students, to improve the students' critical thinking ability for creative problem solving.

EXPECTED LEARNING OUTCOMES

At the end of this course, the student should be able to:

  • Convert common fractions, decimal fractions, and percentages to their corresponding equivalent expressions and apply each in calculations. 

  • Demonstrate an understanding and application of the International System of Units. 
  • Define density, specific gravity, and specific volume and determine each through appropriate calculations 

  • Apply percent strength and ratio strength to calculate the quantity of an ingredient to use 
in compounding a pharmaceutical preparation. 

  • Calculate doses based on factors of age, body weight, and body surface area. 

  • Perform the calculations required to prepare isotonic compounded prescriptions. 

  • Calculate problems involving milliequivalents, millimoles and milliosmoles, active drug moiety in compounding procedures, 
reduction or enlargement of formulas for pharmaceutical preparations stated in metric quantities and in proportional parts, differentiation and integration
