Study-Unit Description


TITLE Pharmaceutical Calculations

LEVEL 01 - Year 1 in Modular Undergraduate Course



DESCRIPTION The study-unit brings to the forefront the various aspects of pharmaceutical calculations as applied to pharmaceutical solutions, semi-solid preparations, pharmaceutical formulae for medicinal products, dose calculations, drug administration and therapeutic drug monitoring.

Topics covered include:
- Percentage Error;
- Ratio Strength;
- Calculation of active drug moiety;
- Calculation of Doses;
- Calculations involving units, concentrations and other measures of potency;
- Dilutions and Solutions;
- Isotonic solutions;
- Intravenous infusions and rate of flow;
- Reducing and enlarging formulas;
- Calculations in contemporary compounding.

Study-unit Aims:

This study-unit will aim to:

- provide the student with an overall idea of important calculations used when preparing pharmaceutical dosage forms and conducting pharmaceutical analysis;
- highlight procedures needed to calculate doses of medicines and pharmaceutical formulations;
- support and reinforce the student with knowledge on pharmaceutical and clinical purposes behind these calculations.

Learning Outcomes:

1. Knowledge & Understanding
By the end of the study-unit the student will be able to:

- acquire the fundamentals of pharmaceutical calculations;
- appreciate relevance of pharmaceutical calculations to pharmaceutical processes in industrial,analytical and clinical settings;
- work out calculations required for the preparation of dosage forms and pharmaceutical solutions;
- know how to apply the workings and answers of calculations to practical scenarios.

2. Skills
By the end of the study-unit the student will be able to:

- plan amounts and calculate dosages needed to prepare pharmaceutical formulations;
- apply knowledge and results of pharmaceutical calculations to practical scenarios;
- predict certain parameters in the pharmaceutical and clinical setting e.g. type of patient-specific dosing needed or determination and prediction of error when calculating and preparing formulations.
