摘要：
The objective of the present investigation was to explore the formulation and evaluation of in situ gel for the nasal delivery of artemether (ARM), a poorly water-soluble antimalarial agent using temperature induced gelation technique using Pluronic with mucoadhesive polymer Hydroxy Propyl Methyl Cellulose (HPMC) K4M in different ratios. Initially, due to low water solubility, an inclusion complex of the antimalarial artemether (ARM) in hydroxypropyl-β-cyclodextrin (HPβCD) was prepared and characterized. The in situ gels so prepared were characterized for its gelation properties, viscosity, gel strength, mucoadhesion, drug content, drug release rate and for its histopathological studies. Pluronic and HPMC based in situ gel (PLH2) showed the effective gelation, viscosity, gel strength and drug release properties along with good mucoadhesive strength, it is further subjected for stability studies carried out at 30 ± 2 °C and 60 ± 5% RH for 90 days in order to know the influence of temperature and relative humidity on drug content and on drug release profile. Histological examination of formulations did not show any remarkable damage to nasal mucosa. The formulation also retained the good stability at accelerated conditions over the period of 90 days. Owing to these properties it can be used as an effective delivery system for the nasal route. These in situ gelling systems would be definitely useful for cerebral malaria.
