Solid Formulation: Excipients Used in Pharmaceutical Dosage Forms

Various pink and purple pills and capsules scattered on a bright yellow background. One prominent round pink pill in the middle of the picture features the letter "M" embossed on it.

Solid dose formulations are one of the most established dosage forms in pharmaceuticals, and yet the path to market can still be blocked by critical obstacles such as active pharmaceutical ingredient (API) stability, release kinetics, and bioavailability limitations.

Our high-quality pharmaceutical raw materials and functionalized excipients form a comprehensive portfolio that addresses all your most pressing challenges in solid formulation manufacturing, with products that include:

When you design a solid dosage formulation, there are many factors to consider: the active pharmaceutical ingredient (API), bioavailability enhancement, release kinetics, specific dosage, packaging, shelf life, and more. Excipients are the backbone of a formulation and affect final formulation properties such as processability, stability and performance. Therefore, it is important to identify an excipient that has the correct functionality and is of high quality.

Our Parteck® functional excipients were designed with these formulator’s challenges in mind and have additional functionalities beyond standard excipients. These excipients are particle optimized and feature unique particle properties tailored for tableting processes, for specific drug delivery technologies, or for solubility enhancement. Thus, our Parteck® functional excipients ensure excellent performance in formulation development and manufacturing. Backed by the Emprove® Program with its stringent quality control, as well as regulatory support and documentation, Parteck® excipients help to speed up your approval processes.
