Routes of drug administration
Objectives:
=> To describe the various routes of drug administration=> To
understand the advantages and disadvantages of the various routes of drug
administration
An alternate method of classifying these routes of administration is ENTERAL
and PARENTERAL. Enteral means to do with the GI tract and includes oral, buccal,
and rectal. Parenteral means not through the alimentary canal and commonly
refers to injections such as IV, IM, and SC; but could also include topical and
inhalation. We can also distinguish IV from the rest, as with all others at
least one membrane must be crossed, thus an absorption process is involved in
the administration and the pharmacokinetics.
