This applies equally to plant powders, ed pills online, along with substances capable of forming sticky and viscous solutions (pectins, mucus), they contain many insoluble and non-swelling particles (starch, particles of various tissues), which are typical plasticizers. The choice of excipients for obtaining a good pill mass depends on the properties of the administered medicinal substances and their amounts. Let us explain this with a few examples.
1. Medicinal substances are insoluble or very slightly soluble in water or other solvent. Two options are possible here: a) medicinal substances are prescribed in very small quantities (for example, substances of list A).
If these substances are mixed with a viscous liquid (for example, with a thick extract of licorice root), then due to the small amount of solid phase, the forming mass will not work. To such a mass, it is imperative to add the optimal amount of powdery insoluble substances in order to give it the necessary plastic properties.
Such substances can be vegetable powders (in the case of extracts), starch, flour; b) medicinal substances are prescribed in significant quantities. In this case, it is usually sufficient to add an optimal amount of a viscous adhesive liquid to obtain a plastic pellet mass. The more pronounced the hydrophobicity of the solid phase, the greater the sticking ability of a viscous liquid.
