A combined nasal spray and aspirator device includes an air pump disposed within a housing and comprises a spray and aspirator assembly. The air pump, at which an air suction connector and an air discharge connector are disposed, is driven by a driving component to perform air suction and discharge actions. The spray and aspirator assembly, mounted to the air suction connector and the air discharge connector, comprises a spray conduit and a first aspiration conduit; the spray conduit connects to an atomizer which is provided with liquids from a liquid storage container, and the first aspiration conduit connects to a mucus collector so that when some air carrying mucus enters the mucus collector, the mucus is left behind and the air enters the air pump through a second aspiration conduit. The device of the present invention integrates the operations of a nasal spray and a nasal aspirator, sucking the mucus away right after it sprays and liquefies the mucus, with said actions occurring almost simultaneously. The present invention is physically more favorable for users.

A nasal spray apparatus for simultaneously administrating metered amounts of multiple medicaments includes chambers for separately storing incompatible medicaments, such as an antihistamine and a steroid. Reciprocal piston pumps allow the medications to be sprayed into the user's nasal cavity. Two pumps can be used to separately transfer the medicaments to a receptacle where they can be initially mixed just prior to administration. A small volume receptacle is used to reduce the amount of mixture remaining after each stroke of the nasal spray apparatus. A check valve can be associated with each pump to further reduce medicament mixtures from cross contamination within storage chamber preparations. Collapsible components, including collapsible storage chambers or balloon capacitors can be employed to compensate for vacuums and back pressures as the medicaments are pumped to a spray nozzle.

The present invention relates to pharmaceutical compositions of various pharmaceutical actives, especially lyophilic and hydrophilic actives containing Diethylene glycol monoethyl ether or other alkyl derivatives thereof as a primary vehicle and / or to pharmaceutical compositions utilizing Diethylene glycol monoethyl ether or other alkyl derivatives thereof as a primary vehicle or as a solvent system in preparation of such pharmaceutical compositions. The pharmaceutical compositions of the present invention are safe, non-toxic, exhibits enhanced physical stability compared to conventional formulations containing such pharmaceutical actives and are suitable for use as injectables for intravenous and intramuscular administration, as well as for use as a preformed solution / liquid for filling in and preparation of capsules, tablets, nasal sprays, gargles, dermal applications, gels, topicals, liquid oral dosage forms and other dosage forms.
