Abstract: Methods and products for delivering a medicament or agent to an individual are provided as well as methods for producing the product. The product includes a coating having a medicament or agent. The medicament or agent is present within the coating that surrounds a tableted gum center (the water soluble portion and a water insoluble base portion). By chewing the gum, the medicament or agent is released from the product. Continuing to chew the chewing gum creates a pressure within the buccal cavity forcing the agent or medicament directly into the systemic system of the individual through the oral mucosa contained in the buccal cavity. This greatly enhances the absorption of the drug into the systemic system as well as the bioavailability of the drug within the system.

The detector analyzes related data for determining th e condition and extent of impurity in the water elements. This data is transmitted from the monitoring unit (2000), that translates the data for output to the CMS (4000), located in another geographic locale, via a common data acquisition network. This network can be the Internet or a cellular and/or satellite connection. Upon detection of contaminants above a treshold level, the monitoring unit (2000) will make a sound through a wall unit located in the vicinity, to warn the average household tap water user of suc h unsatisfactory condition of his/her water elements, as the conditional value s are sent using EDI onto the network, and then onward to the CMS website.</SD OAB>
