The aim of pharmaceutics as a science is to transform drugs of natural or synthetic origin into pharmaceutical products (various drug forms or drug-transferring systems) and enable them to send drugs to the effective locations at the suitable time and for a favorable period, as well as to make drugs acceptable to the patients.

Among such systems one may note to the various drug forms, such as tablets, capsules, syrups, and/or more complex systems including Nano-particles, aimed systems, responsive systems, osmotic pumps, implanting systems, cutaneous patches, and recently, the micro-chips.
