[Glicol plant extracts of anti-inflammatory activity in hydrogels produced on Carbopol base].
Medications originating from plants can be successfully applied in the treatment of rheumatic pain beside those from the nonsteroidal anti-inflammatory drugs (NSAIDs). An attempt was made to produce a new form of a drug applied on skim, which contains NSAID and glycol plant extract in its composition. The aim of the study was to obtain synergy in the area of analgesic and antiinflammatory activity. Formulations containing NSAID (ketoprofen) and formulations containing glycol plant extracts of confirmed anti-inflammatory and analgesic activity (extract from sage, extract form arnica) were produced on the basis of acrylic acid polymers (Carbopol Ultrez 10, Carbopol 980). Moreover, formulations were also produced containing ketoprofen and glycol plant extract in their composition. Viscosity parameters of the tested formulations (structural viscosity, yield stress, thixotrophy)were determined with cone-plate digital rheometer. Potentiometric method was used to measure pH of the produced hydrogels. The test for therapeutic agents pharmaceutical availability was performed with membrane method. Spectrophotometric method was used to estimate the quantity of the released therapeutic agent. The usefulness of acrylic acid polymers (Carbopol Ultrez 10, Carbopol 980) was assessed for the application in the prescription of dermatological hydrogels as well as their compatibility with ketoprofen and active substances contained in glycol plant extracts. Pharmaceutical availability was tested of ketoprofen and therapeutic agents contained in the investigated plant extracts. Furthermore, the effect of the components of extracts on the process of ketoprofen release to acceptor fluid through a semipermeable membrane was estimated.
