Conscious Sedation: Most common routes of drug administration – Oral, Intramuscular (IM), Inhalation and Intravenous (IV).
Oral: The oral route is the most commonly employed route of drug administration. It possesses advantages and disadvantages when compared to other routes of drug administration. Advantages include an almost universal acceptance by patients, ease of administration and relative safety. Unwanted drug effects, such as overdosage, idiosyncrasy, allergy and drug side effects may occur whenever a drug is administered by any route, but such reactions are less likely to develop when a drug is administered orally and when they do develop, they are normally less intense. This is not meant to imply that life threatening situations do not arise following oral drug delivery. Cardiac arrest and analyphylaxis after oral drug administration have occured.
Disadvantages of oral drug delivery include a long latent period, unreliable drug absorption, inability to titrate (easily achieve a desired drug effect) and a prolonged duration of action.
