biodegradable chitosan

ABSTRACTNanoparticles are designed to improve the pharmacological and therapeutic properties of conventional drugs. In the present research work, almotriptan malate was formulated as nanoparticle drug delivery system for the effective management of migraine by ion-gelation technique. Shape and size of the nanoparticles were evaluated by TEM images. FTIR and  DSC studies confirmed that there were no interactions between the drug and the other ingredients. XRD study was carried out to confirm the crystalline or amorphous nature of the nanoparticles. The entrapment efficiency of was found to be 74 to 82% and drug loading capacity was found to be 15 to 16% The in-vitro release studies concluded that the release was sustained after an initial burst. The in vitro mucoadhesion study using goat nasal mucosa was found to be 54% and 69%. The kinetic study revealed that the almotriptan malate nanoparticles followed the first order kinetics.
