Glycerin (laxative) suppositories for insertion into the rectum.
Rectal administration uses the rectum as a route of administration for medication and other fluids, which are absorbed by the rectum's blood vessels,[Note 1] and flow into the body's circulatory system, which distributes the drug to the body's organs and bodily systems.[Note 2]
A drug that is administered rectally will in general (depending on the drug) have a faster onset, higher bioavailability, shorter peak, and shorter duration than the oral route.[1][2] Another advantage of administering a drug rectally, is that it tends to produce less nausea compared to the oral route and prevents any amount of the drug from being lost due to emesis (vomiting). In addition, the rectal route bypasses around two thirds of the first-pass metabolism as the rectum's venous drainage is two thirds systemic (middle and inferior rectal vein) and one third portal (superior rectal vein). This means the drug will reach the circulatory system with significantly less alteration and in greater concentrations.[Note 3] Finally, rectal administration can allow patients to remain in the home setting when the oral route is compromised. Unlike intravenous lines, which usually need to be placed in an inpatient environment and require special formulation of sterile medications,[3] a specialized rectal catheter can be placed by a clinician, such as a hospice nurse or home health nurse, in the home. Many oral forms of medications can be crushed and suspended in water to be given via a rectal catheter.
The rectal route of administration is useful for patients who cannot swallow, including those near the end of life (an estimated 1.65 million people are in hospice care in the US each year[4]). Because using the rectal route enables a rapid, safe, and lower cost alternative to administration of medications,[5] it may also facilitate the care of patients in long-term care or palliative care, or as an alternative to intravenous or subcutaneous medication delivery in other instances.

Methods
A rectal "bulb" syringe that can be used to introduce fluids into the rectum.
Rectal administration of medication may be performed with any of the following:
- A suppository, a drug delivery system inserted into the rectum.
- An enema, the act of introducing a liquid-drug solution (drug(s) dissolved in water, the amount usually being less than 10 millilitres) into the rectum and sometimes the colon (usually when more liquid is used).
- A specialized catheter designed for rectal administration of medications and liquids, that can be placed safely and remain comfortably in the rectum for repeated use.

Notes
- ^ The rectum has numerous amounts of blood vessels available to absorb drugs.
- ^ The organs and systems include, depending on if the drug is able to pass the blood–brain barrier (BBB) or not, the central nervous system (CNS), peripheral nervous system (PNS), cardiovascular system (CVS), et cetera.
- ^ Other ROAs that bypass first-pass metabolism include inhalation (smoking, vaporizing, etc.), intravenous injection (IV), insufflation ("snorting"), et cetera, but the oral route does not bypass first-pass metabolism.
