The present application describes a drug dispensing device. The device is comprised of an armband (1), a rigid housing (2), made of polymeric or composite material, with any geometric shape, which separates in two along the longitudinal axis, incorporating therein a capsule (3) containing a concentrated fluid whose geometric shape allows its storage within said housing. The centre of the top of one of the capsule faces contains a valve (8) which, upon being actuated by at least one flexible tab (4), by pressing the mouth of the user, is expelled from the inside of the capsule, allowing him to suck the concentrated fluid contained therein. In this way, the device allows the user to correct the reference values quickly and effectively and thus regain the sense of physical safety while practicing sports in extreme situations or while practicing activities in water environments.
