Enteral administration is food or drug administration via the human gastrointestinal tract. This contrasts with parenteral nutrition or drug administration (Greek para , "besides" + enteros ), which occurs from routes outside the GI tract, such as intravenous routes.
A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the ...
The parenteral route is any route that is not enteral (par-+ enteral). Parenteral administration can be performed by injection, that is, using a needle (usually a hypodermic needle) and a syringe, [16] or by the insertion of an indwelling catheter. Locations of application of parenteral administration include: Central nervous system:
Lyophilized drugs are stored in vials, cartridges, dual chamber syringes, and prefilled mixing systems. Lyophilization, or freeze drying, is a process that removes water from a liquid drug creating a solid powder, or cake. The lyophilized product is stable for extended periods of time and could allow storage at higher temperatures.
Alexander Wood's main contribution was the all-glass syringe in 1851, which allowed the user to estimate dosage based on the levels of liquid observed through the glass. [12] Wood used hypodermic needles and syringes primarily for the application of localized, subcutaneous injection (localized anesthesia) and therefore was not as interested in ...
In addition to pharmacological effects, rectal administration has some properties which can be advantageous for the use in medicine. Rectal administration can allow patients to remain in the home setting when the oral route is compromised.

An overview of the different components included in the field of chemical biology. Chemical biology is a scientific discipline between the fields of chemistry and biology.The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems.
