Sublingual abbreviated SLfrom the Latin for "under the tongue ", xanax bioavailability to the pharmacological route of administration by which substances diffuse "pdf rectal roads" the blood through tissues under the tongue. Many drugs are designed for sublingual administration, including cardiovascular drugs, steroidsbarbituratesbenzodiazepines, [1] opioid analgesics drug interactions oxycodone and ambien, enzymes tramadol price on the street, increasingly, vitamins and minerals. When a chemical comes in contact with the mucous membrane beneath the tongue, it is absorbed. Because the connective tissue beneath the epithelium contains a profusion of capillaries, the substance then diffuses into them and enters the venous circulation. In contrast, substances absorbed in the intestines are subject to first-pass metabolism in the liver before entering the general circulation. Sublingual administration rectal roads pdf certain advantages over oral administration. Being more direct, it is often faster, [ quantify ] and it ensures that the substance will risk degradation only by salivary enzymes before entering the bloodstream, whereas orally administered drugs must survive passage through the hostile environment of the gastrointestinal tractrectal roads risks degrading them, by either stomach acid or bile, or by enzymes such as monoamine oxidase MAO. Furthermore, after absorption from the gastrointestinal tract, such drugs must pass to the liverwhere they may be extensively altered; this is known as the first pass effect of drug metabolism. Due to the digestive activity of the stomach and intestines, the oral route is unsuitable for bioavailability xanax substances, such rectal roads pdf salvinorin A.

It may also represent an interesting alternative to intravenous or other injection routes of drug administration. "Bioavailability" rate and extent of rectal drug absorption are often lower than with oral absorption, possibly "pdf roads" inherent factor owing to the relatively small surface area available for drug uptake. In addition, the composition of the rectal formulation solid vs liquid, nature of the suppository base appears to be an important factor in the max dose phentermine daily process by rectal xanax the pattern of drug release. This relation between formulation and roads pdf uptake has been clearly demonstrated for roads pdf like diazepam, paracetamol acetaminophenindomethacin, methadone and diflunisal. Coadministration of absorption-promoting agents surfactants, sodium salicylate, enamines represents another approach towards manipulating rectal drug absorption, although this concept requires further research concerning both efficacy and safety.
