“…Women are more likely to experience PONV than men, as are non-smokers, younger patients, volatile anaesthetics (either nitrous oxide or not), and opiate use. Significant postoperative discomfort and dissatisfaction are only the first issues that PONV brings about [2]. Since its introduction to clinical practice in 1970 as an atypical antipsychotic, amisulpride (AMS) has proven to be a very effective and selective antagonist of dopaminergic D2 and D3 receptors.…”

This research aimed to create and refine intranasal mucoadhesive amisulpride-loaded nanostructured lipid carriers (AMS-MNLCs) to increase efficacy and safety by increasing nasal-mucosal adhesion and facilitating direct brain targetability. Using HPMC K4M, Carbopol 934, and Hyaluronic acid (HA), AMS-MNLCs were made by applying modified melt-emulsification and ultra-sonication procedures. The results of the pH, osmolarity, and mucoadhesive tests on the optimized formulation were 6.3 ± 0.02, 304.53 ± 2.15, and 26.07 ± 0.37, respectively. Rheological investigation, in-vitro release and ex-vivo permeation study of the optimized formulation revealed a shear-thinning behaviour, significantly higher release, and the flux of the drug from the formula was 975.2 ± 12.45. Based on the pharmacokinetic analyses in rats, intranasal AMS-MNLCs were reported to have a brain Cmax about 14 times higher than intravenous AMS-solution. In addition, two weeks of intranasal administration of formulation did not affect haematological parameters in the in vivo research. The histopathological investigation showed that there was no disruption of the naso-mucosal membrane structure. Therefore, the created and optimized intranasal MNLCs showed a promised venue for the efficient and secure delivery of AMS as an antiemetic drug for the prevention and treatment of preoperative nausea and vomiting (PONV). RezumatStudiul prezintă dezvoltarea unor nano-purtători lipidici mucoadezivi intranazali (AMS-MNLC) încărcați cu amisulprid, cu scopul creșterii eficacității și siguranței prin mărirea aderenței mucoasei nazale și facilitarea țintirii directe a creierului. Folosind HPMC K4M, Carbopol 934 și acid hialuronic (HA), purtătorii nanostructurați au fost obținuți prin proceduri modificate de emulsionare în topitură și ultrasunete. Rezultatele testelor de pH, osmolaritate și mucoadezivitate pentru formularea optimizată au fost 6,3 ± 0,02, 304,53 ± 2,15 și, respectiv, 26,07 ± 0,37. Investigația reologică, cedarea in vitro și studiul de permeație ex-vivo ale formulării optimizate au evidențiat un comportament de subțiere prin forfecare, eliberare semnificativ mai mare, iar fluxul medicamentului din formulă a fost de 975,2 ± 12,45. Pe baza analizelor farmacocinetice la șobolani, s-a observat că AMS-MNLC intranazal au o Cmax cerebrală de aproximativ 14 ori mai mare decât soluția intravenoasă de AMS. În plus, două săptămâni de administrare intranazală a formulării nu au afectat parametrii hematologici in vivo. Investigația histopatologică a arătat că nu a existat nici o perturbare a structurii membranei nazale. Prin urmare, purtătorii nanolipidici cu administrare intranazală obținuți au permis o cedare eficientă a AMS, folosit ca medicament antiemetic pentru prevenirea și tratamentul sindromului de greață și vomă preoperatorie (PONV).
