Assembled modules technology for site-specific prolonged delivery of norfloxacin.

The aim of this research was to design and study norfloxacin (NFX) release in floating conditions from compressed hydrophilic matrices of hydroxypropylmethylcellulose (HPMC) or poly(ethylene oxide) (PEO). Module assembling technology for drug delivery system manufacturing was used. Two differently cylindrical base curved matrix/modules, identified as female and male, were assembled in void configuration by friction interlocking their concave bases obtaining a floating release system.

Artesunate-clindamycin multi-kinetics and site-specific oral delivery system for antimalaric combination products.

The aim of this work was to study a multi-kinetics and site-specific oral antimalaria drug delivery system (MKS_DDS), containing artesunate and clindamycin, based on the Dome Matrix module assembly technology. The MKS_DDS assembled system comprises of four modules, i.e.
