Extract from Zingiber officinale Rosc. in oral solid form of a drug



It has been decided to investigate the usefulness of selected acrylic acid polymers (Carbopols), chitosan and microcrystalline cellulose as dominating carriers of dry extract from ginger rhizome (Zingiber officinale Rosc.) in an oral solid form of a drug. The aim of the study was to obtain tablets in the course of direct tableting of controlled release of biologically active substances. Seven batches of tablets were manufactured in reciprocating instrumented tableting machine and the effect of the kind of applied adjuvant substances on the rate of biologically active substances release from the produced tablets was evaluated. Physicochemical parameters were determined in order to test the produced tablets. The tablets containing acrylic acid polymers (Carbopol 71 GNF, Carbopol 974 PNF) demonstrated the highest hardness. The tests of pharmaceutical availability of biologically active substances from tablets to the acceptor fluid 0,1 mol/l HCl and comparatively to hydrating intervention hypotonic fluid and to pediatric compensating fluid were performed. The investigations fulfilled general and detailed requirements of Polish Pharmacopoeia VII. Tablets containing Carbopol 71 GNF as dominating carrier of the extract, Vivapur 112 and Prosolv HD 90 demonstrated high pharmaceutical availability. Introduction of Prosolv SMCC 50 together with dominating carriers of the extract had a beneficial effect on pharmaceutical availability of biologically active substances from the tested tablets. It results from the carried out investigations that the kind of the applied adjuvant substances and differentiated osmolarity of model acceptor fluids significantly decide on pharmaceutical availability of hydrophilic therapeutic agents contained in dry extract from ginger rhizome. The adjuvant substances applied in adequate proportions appeared to be useful for manufacturing tablets containing dry extract from ginger rhizome.
