[Selected adjuvants as carriers of a dry extract of common ivy (Hedera helix L.)].

The usefulness was tested of selected adjuvants: Vivapur 112, Carmellose calcium, Calcium carbonate CA 740, Calcium carbonate CA 800, Hypromellose as carriers of a dry extract of common ivy (Hedera helix L.) leaves in the process of direct tableting. The quality of the produced tablets was determined by examining their appearance, diameter, thickness, mass resistance to abrasion, crushing and disintegration time.

The effect of chitosan on the stability and morphological parameters of tablets with Epilobium parviflorum Schreb. extract.

The study is a continuation of research on manufacturing oral solid drug form containing extract from Epilobium parviflorum Schreb. This study aims at investigating the usefulness of selected high-molecular substances with particular consideration of chitosan (Ch), silicified microcrystalline cellulose (Prosolv) and croscarmellose sodium (Vivasol) as a carrier of E. parviflorum Schreb.

Application of silicified microcrystalline cellulose (Prosolv) as a polymer carrier of Epilobium parviflorum Schreb. extract in oral solid drug form.

Direct tableting is simpler and more cost-effective from the point of view of good manufacturing practice (GMP) than wet granulation or dry compacting. Thus, pharmaceutical industry more and more frequently uses this particular process. Only few therapeutic substances form under compression tablets meeting current requirements.
