Chapter One — 1.1 Background to the Study

Research interest in particle size reduction method has grown steadily in recent years, driven by its demonstrated relevance to locally sourced excipients in both laboratory and field settings.

Much of the existing literature on particle size reduction method draws on data and conditions that differ from the local context in which locally sourced excipients is typically studied or produced, limiting the direct applicability of prior findings to dissolution rate.

1.2 Statement of the Problem

There is currently limited empirical evidence on how particle size reduction method affects dissolution rate in locally sourced excipients, making it difficult for researchers and practitioners to draw reliable, context-appropriate conclusions. This study addresses that gap through a structured investigation.

1.3 Objectives of the Study

1. To determine the effect of particle size reduction method on dissolution rate of locally sourced excipients.
2. To evaluate the extent to which particle size reduction method influences dissolution rate.
3. To identify the conditions under which particle size reduction method has the greatest effect on dissolution rate.
4. To recommend practices based on the observed relationship between particle size reduction method and dissolution rate.

1.4 Research Questions

1. What is the effect of particle size reduction method on dissolution rate of locally sourced excipients?
2. To what extent does particle size reduction method influence dissolution rate?
3. Under what conditions does particle size reduction method have the greatest effect on dissolution rate?
4. What practices can be recommended based on this relationship?

1.5 Significance of the Study

This study is significant to researchers and practitioners working with locally sourced excipients, offering evidence on how particle size reduction method relates to dissolution rate. It also contributes to the broader literature in pharmacy by documenting findings specific to the conditions under which the study was conducted.

1.6 Scope of the Study

The study is limited to examining Particle Size Reduction Method and its relationship with dissolution rate in locally sourced excipients, reflecting a clearly defined scope of analysis; conclusions are drawn strictly from the conditions and samples used in the study.
