After synthesis, the crude API needs to be purified to eliminate impurities and obtain the desired purity level, often 98% or higher. Common purification techniques include recrystallization, distillation, chromatography, and membrane filtration. Each technique has its advantages and is selected based on the specific characteristics of the API. The purification process is critical as impurities can significantly impact the safety and efficacy of the final pharmaceutical product.

On the other hand, excipients are the non-active components of a drug formulation that serve as vehicles for the API. They may enhance the stability of the medication, aid in the manufacturing process, improve taste, or assist in the drug's absorption in the body. Common excipients include fillers, binders, preservatives, and flavoring agents. For instance, lactose is often used as a filler in tablets, while magnesium stearate serves as a lubricant during production. Although they do not provide therapeutic effects, excipients can influence the bioavailability and efficacy of the active ingredients, making their selection critical in drug formulation.
