In pharmaceutical terms, a solution is defined as a homogenous mixture, meaning that the components are uniformly distributed throughout the mixture. In a solution, the solute (the substance that is dissolved) is completely integrated into the solvent (the liquid that does the dissolving), resulting in a single phase that has consistent composition and properties throughout. This characteristic is essential in pharmaceuticals because a uniform solution ensures that each dose contains the same amount and concentration of the active ingredient, which is crucial for efficacy and safety in medication administration.

On the other hand, a heterogeneous mixture is one where the different components remain distinct and can often be visually identified, which does not apply to solutions. Additionally, powdered medications and tablets are forms of drug delivery but do not represent the concept of a solution itself; they can be dissolved to form a solution but are not inherently homogeneous mixtures on their own. Thus, understanding the definition of a homogenous mixture is vital in the context of pharmaceutical science and medication preparation.
