Abstract: The paper presents the results of correlated in vitro release and rheological assessment of hydrophilic gels containing organometallic complexes of copper and cobalt with piroxicam and tenoxicam. The semisolid experimental formulations intended for local delivery after application onto the skin were prepared based on polyoxyethylene-polyoxypropylene copolymers (Poloxamer 407). The results confirmed that the diffusion process of the hydrophobic compounds had long lag-times and release rates depending upon the affinity of the complex for the semisolid matrix. Higher consistency due to particular internal interactions generated decreased release rates. All formulations presented a pseudoplastic behavior, adequately described by Ostwald de Waele model.
Keywords: organometallic complexes, cobalt, copper, oxicam ligand, in vitro release, hydrogels.
