The present invention provides a double formulation packaging pouch with easy-opening and easy-liquid drinking features, which includes: a pouch body having a hollow storage space formed by sealing both ends of a rectangular packaging film; an upper sealed part formed by sealing an upper opening of the pouch body; a lower sealed part formed by sealing a lower opening of the pouch body; a sealed partition part formed by connecting a first partition line extending downward and a second partition line extending laterally with each other, then sealing front and rear sides of the packaging pouch along the first and second partition lines, to form a pill storage compartment and a potion storage compartment; a cutting line part formed at an upper portion of the pouch body by penetrating at least one layer; and a cutting notch formed by cutting away a predetermined section of the upper sealed part.

Disclosed herein are materials, articles of manufacture, and methods for reducing, mitigating, or precluding formation of and/or amount of a nitrosating agent and/or an N-nitroso compound, including an N-nitrosamine, from a packaging containing an active agent and a pharmaceutical dosage form in an enclosure, wherein the active agent is effective to reduce mitigate or preclude the formation and/or amount of a nitrosating agent and/or N-nitroso compound in the enclosure and/or in the pharmaceutical dosage form. Provided are drug delivery systems comprising a blister pack configured to house multiple pharmaceutical dosage forms, the blister pack comprising an active ingredient that is effective to reduce, mitigate or preclude the formation and/or amount of a nitrosating agent and/or N-nitroso compound in an enclosure of the blister pack and/or in the pharmaceutical dosage form.

Disclosed herein are modular container systems having child-resistant containers, tray inserts and tray frames. Also disclosed are methods using the modular container systems and methods of storing substances in containers. The containers have a container base and a container cap and provide for child-resistant containers. A user can releasably remove the container cap from container base with a squeeze and lift sequence. For example, the user squeezes opposite sides of the container base, which releases a locking mechanism and allows for removal of the cap by lifting or pulling the container cap off from the container base. The components of the modular container system are modular and stackable. The modular system allow for organized, efficient, accessible and storage of the child-resistant containers. The modular container system also allows for easy counting, sorting and processing of the containers.
