Drug delivery is described as the localized sustained delivery of a pharmaceutical agent to the systemic blood circulation and hence to the site of action to produce a desired pharmacological effect [1]. There are three principle ways of drug delivery, first being the injection of the drug loaded on microspheres in this method of drug delivery, microspheres are formed using a combination of ink-jet technology and single emulsion-solvent evaporation techniques. Microspheres of a certain size are produced such as to administer the desired route of administration and the rate of the drug release [1]. Another form of drug delivery commonly used is called a transdermal drug delivery, in which the skin is used as a medium to administer the delivery of a drug. Different technologies are being used to dispense and print drugs on the skin.
