Abstract:V diplomskem delu je predstavljeno formuliranje farmacevtskih učinkovin s PGSSTM procesom. Mikronizacijo smo izvedli s pomočjo superkritičnega CO2 in treh različnih aktivnih učinkovin (fenofibrat, nimodipin in O-vanilin) in dveh polimerih nosilcev (Brij S100 in PEG 4000). Vzorce smo pršili skozi šobo premera 1 mm pri 60° naklonu po 1 h homogenizacije. Eksperimente smo izvajali pri štirih različnih tlakih (10 MPa, 15 MPa, 20 MPa in 25 MPa) in pri dveh različnih koncentracijah (2 g učinkovine in 4 g učinkovine na 20 g nosilca). Po končani mikronizaciji smo izračunali izkoristek pršenja in vzorce poslali na analizo velikosti mikro delcev s postopkom CILAS, kjer smo dobili podatke o velikosti srednjega zrna, najmanjših in največjih delcih ter graf njihove porazdelitve. Nato smo vzorce analizirali s pomočjo tekočinske kromatografije z masno spektrometrijo, kjer smo dobili kot rezultat masne spektre in kvantitativne vrednosti učinkovin znotraj vsakega posameznega vzorca, iz katerih smo izračunali dejansko prisotnost učinkovine v vzorcu po PGSSTM procesu. Vzorce smo analizirali tudi z elektronskim mikroskopom (SEM), da smo dobili podatke o morfološki sestavi in formulaciji učinkovine v nosilcu.

Title:Formulation of pharmaceutical substances using a PGSS process
Abstract:Formulation of phaurmaceutical substances with PGSSTM process is presented in the thesis. Micronization of three different active substances (Fenofibrate, Nimodipine, O-vaniline) with supercritical CO2 has been investigated. Two different polymers (Brij S100 and PEG 4000) have been used as carriers. Samples have been sprayed through the nozzle of 1 mm diameter at 60 o incline after 1 hour of homogenization. Experiments were carried out at four different pressures (10 MPa, 15 MPa, 20 MPa, 25 MPa) and two different concentraions (2 g or 4 g of active substance per 20 g of carrier). After completed micronization, process efficency has been evaluated and the samples were sent to the size analysis by the CILAS procedure, to obtain data on the size of the middle grain, sizes of the smallest and the largest particles and also the distribution diagrams. Micronized samples were analyzed by liquid chromatography coupled with mass spetrometry, resulting in mass spectra and quantitative evaluation on presence of active substance in samples after PGSSTM process. Two samples were also analyzed by a scanned electron microscope (SEM) to obtain images of a sample by scanning its surface.
