Main Research Findings

The research focused on developing a thermoreversible nasal gel using Pluronic PF 127 to improve vitamin B12 absorption and patient compliance. The study investigated the impact of vitamin B12 and gel additives (PF concentration, osmolarity, polyethylene glycol (PEG 15000)) on the thermodynamic properties of phase transitions at gelation (T(1)) and gel melting (T(2)). 1

The results revealed that increasing vitamin B12 and PF concentration led to a decrease in T(1) and an increase in T(2). The addition of sorbitol and PEG narrowed the gelation range. The suppression of T(2) was significantly higher than T(1) with both additives. A semilogarithmic plot of PF concentration and 1/T(2) showed linearity only for sorbitol and PEG, suggesting a significant interaction between them during gel melting. The enthalpy of both transitions remained unchanged with vitamin, indicating no interaction with the polymer. Benzalkonium chloride reduced the gelation onset temperature. These findings demonstrate that the thermodynamic properties of PF 127 gels are significantly influenced by polymer concentration and water-soluble formulation additives.
