A method of intranasal drug delivery including administering a multi-compartment nanoemulsion to a nasal cavity of a subject in need thereof, where the multi-compartment nanoemulsion includes a water-in-oil core emulsion having an oil phase encompassing a first aqueous phase, the oil phase comprising a first surfactant and a fatty acid and the first aqueous phase comprising levetiracetam and valproic acid dissolved therein. The multi-compartment nanoemulsion further includes a second aqueous phase encompassing the water-in-oil core emulsion, the second aqueous phase comprising a second surfactant and a co-surfactant in a ratio of the second surfactant to the co-surfactant of 1:4 to 4:1. The multi-compartment nanoemulsion has an average droplet size of less than 100 nm and a polydispersity index (PDI) of 0.1 to 0.2.

The present invention relates to a solid pharmaceutical composition manufactured by a wet granulation method comprising levetiracetam or pharmaceutically acceptable salts thereof, at least one or more disintegrant, at least one or more diluent, at least one binder, at least one glidant, at least one lubricant, and one or more pharmaceutically acceptable excipients. The orodispersible tablet prepared using these excipients exhibits desirable properties such as facilitating disintegration, and dissolution of the drug for oral administration. Further, the present invention also relates to the process for preparing the said solid pharmaceutical composition.
