Capsules and tablets:
Tablets and capsules are the most common forms of oral dosing. These preparations differ from each other in that the substances within the capsules are less affected by the medium than compressed tablets. Once the capsule dissolves, a rapid dispersion of the components occurs. Although the capsule dissolves in water, it can block the dissolving of the drug by interfering with the drug, but this is not common. The disks usually decompose in several stages, turning first into granules and then to elementary particles. The smaller the size of the particles, the greater the melting rate due to the increased surface area.
Disc dissociation is a sufficient criterion for predicting biological absorption within the body. It was considered to be an insufficient criterion and solubility was considered a better criterion now. Regulatory agencies currently have data on the rate of the biological solubility of all new oral formulas. The widespread acceptance of solubility as the best parameter in glass for predicting bio-absorption is reflected in the increase in these tests in the official abstracts.
Excipients. With active substances in tablets and capsules and a variety of so-called inactive ingredients, for example: starch, magnesium aluminum silicate, methylcellulose, carboxymethylcellulose, lactose, kaolin, talc, calcium sulfate and magnesium stearate. The tablets have a variety of coatings to increase consistency, conceal the taste, improve appearance and release properties. These additives, although considered inactive, can affect the solubility and absorption of the drug. Changing the excitability of calcium sulphate to lactose and increasing magnesium silicate content increases the activity of oral phenytoin. The systemic availability of thiamine and riboflavin decreases with the presence of Fuller's earth. Tetracycline uptake of capsules is reduced by calcium phosphate due to formation of complexities.
Most of these types of interactions have been publicized for some time and have been unlikely in the current environment for ongoing tests of modern forms and preparations.
