  • Patent number: 9422079
    Abstract: A selectively frangible shipping carton for storing and shipping goods comprises at least one side wall joining a top wall and a bottom wall. A path of weakness extends around a periphery of the carton through at least a portion of the side wall. The path of weakness enables a user to manually separate the carton into at least two portions: an upper portion including the top wall and a lower portion including the bottom wall. A pair of lines of weakness extends upwardly relative to the path of weakness and terminates at or adjacent the top wall. A grip flap defined in the side wall between the pair of lines of weakness, the grip flap being graspable by the user when separating the carton into the at least two portions.

  • Patent number: 9145254
    Abstract: A medicament dispenser comprises a housing having opposing first and second walls. A connecting assembly is associated with at least one of the first and second walls to facilitate connection of the first and second walls to one another. A blister pack containing the medicament is pivotally connected to the connecting assembly so as to be rotatable about the connecting assembly and about an axis of rotation substantially orthogonal to the first and second walls to facilitate movement of the blister pack from: i) a closed position in which the blister pack is substantially enclosed within the housing; and ii) an open position in which the blister pack is at least partially rotated from the housing.

  • Patent number: 8911773
    Abstract: A peelable pouch comprises a substantially flat enclosure formed by first and second opposing flexible plies. A seat extends along at least a portion of a perimeter of the opposing plies. A flat, flexible transdermal patch is disposed in the enclosure and includes a bioactive agent dissolved in a layer of adhesive. A release liner is removably attached over the layer of adhesive, with the patch and the release liner together being sufficiently resilient so as to generate a spring force when displaced out of the flat configuration. The first and the second plies each being separable along the seal and displaceable out of the flat configuration. The spring force generated by the patch and the release liner being sufficient to overcome an adhesive force created by the adhesive between the patch and one of the plies.

  • Patent number: 8765178
    Abstract: A pharmaceutical formulation having a geometric configuration that affects the release characteristics of active agents contained therein and associated methods are provided. In one aspect, a sustained release oral dosage pharmaceutical tablet may include a first layer having a first active agent, where the first layer is disposed between two adjacent controlled release layers, at least one of the adjacent layers including at least one second active agent. The two adjacent layers are arranged such that they cover a portion of the first layer. The two adjacent layers may be separate layers or they may be joined into a single continuous layer, depending on the overall configuration and geometric design of the oral dosage form.

  • Patent number: 8550249
    Abstract: A medicament dispenser can include a first side surface, a second side surface spaced from and substantially opposed to the first side surface, and a medicament packaging structure located between the first side surface and second side surface. A pivot structure can extend between the first side surface and the second side surface, and the medicament packaging structure can be rotatable about the pivot structure. Thus, the medicament packaging structure can be rotated from an enclosed state in which the medicament packaging structure is substantially enclosed by the first side surface and/or second side surface, to an exposed state in which the medicament packaging structure is substantially exposed from at least one of the first side surface and/or second side surface to provide user access to the medicament(s) stored in the medicament packaging structure.

  • Patent number: 8241662
    Abstract: The present invention provides compositions and methods for administering oxybutynin while minimizing the incidence and or severity of adverse drug experiences associated with oxybutynin therapy. In one aspect, these compositions and methods provide a lower plasma concentration of oxybutynin metabolites, such as N-desethyloxybutynin, which is presumed to be contributing at least in part to some of the adverse drug experiences, while maintaining sufficient oxybutynin plasma concentration to benefit a subject with oxybutynin therapy. The invention also provides isomers of oxybutynin and its metabolites that meet these characteristics of minimized incidence and/or severity of adverse drug experiences, and maintenance of beneficial and effective therapy for overactive bladder. In some aspects, the composition may be presented in the form of an unoccluded or free form topically administered gel.
