Abstract: The invention relates to a bottle for packaging a liquid with dropper delivery comprising a reservoir with an elastically deformable wall that can be reversed by letting air into the receptacle, surmounted by a dispensing head for the liquid comprising a drop-counting end-piece protruding to the outside of the bottle and an anti-bacterial filtering membrane, made partially hydrophilic and partially hydrophobic, which is interposed across the path of the liquid and of the air, at the base of the said end-piece. The dispensing head comprises an insert with a recessed body which contains a porous pad regulating the flow of liquid placed downstream of the reservoir and upstream of a chamber delimited downstream of the said membrane. At the base of this insert on the inner side of the bottle, longitudinal arches supporting a central pellet make star-shaped passageways radially guiding the air that enters the bottle after having passed through the porous pad.

Abstract: This invention concerns an ophthalmic solution including: at least one prostaglandin; a solubilizing agent; a gelling agent of the carbomer type; a carbomer polymerization-inhibiting agent; a co-gelling/co-solubilizing agent.

Abstract: The present invention relates to a bottle for packaging a liquid to be distributed drop by drop comprising a reservoir the walls of which can be reversibly elastically deformed by letting air into the container, surmounted by a liquid dispensing head comprising a dropper nozzle protruding from the bottle and an anti-bacterial filter membrane, that is partially hydrophilic and partially hydrophobic, interposed across the path of the liquid and the air, at the base of the said nozzle. In the dispensing head, the proposal is to create the nozzle by itself out of a material containing a bactericidal agent that has the effect of preventing any bacterial growth on the surface of the said nozzle on the outside of the antibacterial membrane. A porous core is advantageously positioned inside the duct through which liquid is expelled and air is admitted.

Abstract: The present invention provides an ophthalmic solution without an antimicrobial preservative. The solution includes as an active substance at least one prostaglandin and as a solubilizing agent, a surfactant, where the solubilizing agent is polyoxyl-15-hydroxystearate.
