Emulsions are used for oral, topical, or parenteral applications to deliver drugs with improved […]
Colloidal particles exhibit diverse sizes and shapes, ranging from nanoparticles to microparticles with spherical, elongated, or irregular geometries. Understanding the size and shapes of colloidal particles is crucial for designing and tailoring their properties for specific applications in fields such as nanotechnology, materials science, and biomedicine. Classification of Colloids Colloids are heterogeneous mixtures composed of […]
The World Health Organization (WHO) defines a dosage form as follows: “A pharmaceutical product, in the form in which it is presented for use, containing one or more active ingredients usually mixed with excipients.” In pharmaceuticals, a unique way to make medicine for patients is a dosage form.
