Abstract: Embodiments include a system including a sealed prefilled drug-reservoir. The drug-reservoir may include a unit dosage of treprostinil in a sterile fluid composition. The composition may not include an antimicrobial preservative. The treprostinil may be present at a dosage of between 0.1 mg/mL and 25 mg/mL. In addition, the treprostinil may be treprostinil sodium Furthermore, the composition may include sodium chloride. The composition may also include a sodium ion from sodium chloride in a concentration from 3000 to 4500 ppm. The composition may not include metacresol.

Abstract: The present invention provides an infusion-patch comprising; a cannula; a base; at least one adhesive region in said base suitable for skin attachment; at least one skin-access area within said base; and at least one conduit in fluid connection with said at least one skin access area, wherein said at least one conduit in fluid connection with said at least one skin access area facilitates the transfer of an anesthetic substance within at least a first anesthetic-reservoir which may be removably attached and in fluid connection with said at least one contact area, promoting delivery of said anesthetic substance to said at least one skin-access areas, and wherein said anesthetic substance delivered to said skin-access areas may be at least partially replenished without removing said infusion-patch. Embodiments of the present invention include methods of administering a drug using the infusion-patch.
