nobody mention brand names please
subL test p is cyclodextrin based - should be fine in theory - it dissolves under the tongue or along the gums and goes directly into the bloodstream

I read the net absorbtion is much much less than IM and is subject to a host of factors that could make consistent dosing an issue--minimal, but an issue.

Here are a few references on the benefits of Sublingual Absorption:
--------------------------------------------------------------------------------
Wikipedia
Sublingual, literally 'under the tongue', from Latin, refers to a pharmacological route of administration in which certain drugs are entered directly into the bloodstream via absorption under the tongue. Many pharmaceuticals are prepared for subligual administration. These commonly include cardiovascular drugs, steroids, barbituates, some enzymes and increasingly frequently, certain vitamins and minerals.
The principle behind sublingual administration is fairly simple. When a chemical comes in contact with the mucous membrane, or buccal mucosa, it diffuses into the epithelium beneath the tongue. This region contains a high density of blood vessels, and as a result, via osmosis, the substance quickly enters the blood stream at the sublingual artery. Quickly thereafter, the substance is carried by blood flow to the connected lingual artery, which takes up the chemical and translates it to its source: the carotid artery. This artery is connected directly to the brain.
In theory, sublingual routes of administration have certain advantages over simple oral administration. This route is often faster, and entering a drug into one's body sublingually ensures that the substance will only come in contact with the enzymes in saliva prior to entry into the bloodstream. Drugs otherwise orally administered must instead rely upon the incredibly hostile environment of the gastrointestinal tract. This may mean a much greater percentage of the original substance is degraded either by the myriad of enzymes in the GI tract, such as monoamine oxidase, or the strong acids it contains. Additionally, after GI absorption, the drug is sent to the liver where the drug may be extensively metabolized; this is known as the first pass effect of drug metabolism. Due to the degradative qualities of the stomach and intestine, or the solubility of the GI tract, certain substances, such as salvinorin A may only be administered orally via the sublingual route.

--------------------------------------------------------------------------------
Sublingual drug delivery refers to any method of administering medicine so that it can be absorbed directly into the bloodstream through the rich layers of blood vessels found on the bottom of the tongue. Compared to commonly used tablets, capsules and other oral dosage forms, sublingual absorption is generally much faster and more efficient. Products passing through the digestive tract are subject to a "first pass" effect, in which many of the ingredients may be broken down by stomach acid or metabolized by the liver.
Peak blood levels of most products administered sublingually are achieved within 10-15 minutes, which is generally much faster than when those same drugs are ingested orally.
Sublingual absorption is efficient. The percent of each dose absorbed is generally higher than that achieved by means of oral ingestion.

A drug placed between the gums and cheek (buccal administration) or under the tongue (sublingual administration) is retained longer so that absorption is more complete.

--------------------------------------------------------------------------------
The absorption mechanism under the tongue is different than that in the GI tract. Materials absorb directly into the circulatory system under the tongue; they do not pass to the liver and then out into systemic circulation.

There is considerable evidence that most sublingual substances are absorbed by simple diffusion; the sublingual area acting rather like litmus paper, readily soaking up the substances. However, not all substances are permeable and accessible to the buccal mucosa. The mucosa functions primarily as a barrier - similar to skin. But while it was once believed that the barrier of human skin was 'impenetrable' it is now recognised that the dermis is a good site for the absorption of many substances (eg, vitamins E & C creams; hormones; nicotine patches) and it is a growing field of endeavour.
Similarly the buccal mucosa presents an ideal site for absorption.
This potential continues to be explored for the administration of many drugs - providing many useful studies and a better understanding of the modus operandi - although the benefits of the less intrusive nutrition therapies have had little opportunity as yet to be as thoroughly researched.
One of the best known drugs used regularly with great success is Glyceryl Trinitrate - a potent coronary vasodilator which is used for the rapid symptomatic relief of angina. It has been found impressively effective when administered sublingually; pharmacologically active after only 1 - 2 minutes.
Impressive absorption has been attained with sublingual administration of desoxycortisone acetate, morphine, captoprill, nifedipine and 17-B Oestradiol - interestingly, it has also been shown that the sublingual administration of 17-B Oestradiol requires only 1/4 of the oral dose.

Sublingual Absorption
Some drugs are taken as smaller tablets which are held in the mouth or under the tongue. These are buccal or sublingual dosage forms. Buccal tablets are often harder tablets (4 hour disintegration time), designed to dissolve slowly. Nitroglycerin, as a softer sublingual tablet (2 min disintegration time), may be used for the rapid relief of angina. This method is also used for some steroids such as testosterone and oxytocin. Nicotine containing chewing gum may be used for cigarette smoking replacement.
Advantages:
First pass - The liver is by-passed thus there is no loss of drug by first pass effect for buccal administration. Bioavailability is higher.
Rapid absorption - Because of the good blood supply to the area absorption is usually quite rapid.
Drug stability - pH in mouth relatively neutral (cf. stomach - acidic). Thus a drug may be more stable.
Disadvantages:
Holding the dose in the mouth is inconvenient. If any is swallowed that portion must be treated as an oral dose and subject to first pass metabolism.
Only small doses can be accommodated easily.

Sublingual absorption is 3 to 10 times greater than oral administration absorption and is only surpassed by hypodermic injection.

If you take EDTA sublingually (under the tongue), your absorption level compared with oral chelation goes from 5-18 percent absorption for oral capsules to 60 percent for sublingual absorption. http://www.naturodoc.com/mm5/mercha...uct_Code=DS-OraChel-01&Category_Code=Vitamins

Vitamin B-12 studies show that Sublingual B-12, B-6 & Folic Acid is readily absorbed into the bloodstream, raising blood levels on average by 90%. B-12 that is taken orally, not sublingually, only increases blood levels by 1.2%.

Sublingual absorption of selected opioid analgesics.
Weinberg DS, Inturrisi CE, Reidenberg B, Moulin DE, Nip TJ, Wallenstein S, Houde RW, Foley KM., Department of Neurology, Memorial Sloan-Kettering Cancer Center, New York, NY.
Ongoing interest in the improvement of pain management with opioid analgesics had led to the investigation of sublingual opioid absorption. The present report determined the percent absorption of selected opioid analgesics from the oral cavity of normal subjects under conditions of controlled pH and swallowing when a 1.0 ml aliquot of the test drug was placed under the tongue for a 10-minute period. Compared with morphine sulfate at pH 6.5 (18% absorption), buprenorphine (55%), fentanyl (51%), and methadone (34%) were absorbed to a significantly greater extent (p less than 0.05), whereas levorphanol, hydromorphone, oxycodone, heroin, and the opioid antagonist naloxone were not. Overall, lipophilic drugs were better absorbed than were hydrophilic drugs. Plasma morphine concentration-time profiles indicate that the apparent sublingual bioavailability of morphine is only 9.0% +/- 11.9% (SD) of that after intramuscular administration. In the same subjects the estimated sublingual absorption was 22.4% +/- 9.2% (SD), indicating that the sublingual absorption method may overestimate apparent bioavailability. When the oral cavity was buffered to pH 8.5, methadone absorption was increased to 75%. Thus, an alkaline pH microenvironment that favors the unionized fraction of opioids increased sublingual drug absorption. Although absorption was found to be independent of drug concentration, it was contact time dependent for methadone and fentanyl but not for buprenorphine.
These results indicate that although the sublingual absorption and apparent sublingual bioavailability of morphine are poor, the sublingual absorption of methadone, fentanyl, and buprenorphine under controlled conditions is relatively high.

Original Viagra is absorbed through the gut and takes 60-90 minutes to take effect, thereby eliminating any spontaneity in the sexual encounter. Sublingual absorption revolutionized the speed of Sildenafil Citrate. The new process decreases the time for the drug to be absorbed and weave its magic to as little as 15-20 minutes.
The beneficial effect of the Lozenge form is that you have considerably more control over when and how you decide to have sex.

Sublingual absorption begins in the mouth - under the tongue and through the cheek
Homeopathic remedies are administered by sublingual absorption. This requires them to be sprayed under the tongue where they are absorbed directly into the bloodstream, bypassing the digestive tract. http://www.avon.com/avonfaq/default...e=qa&oldlevel=4643&category=Homeopathy+Sprays

`The suggestion is often made that metals in the colloidal form will continue to circulate for a long time in the blood: this is incorrect, as several workers have shown. Duhamel found that when colloidal silver was injected into a rabbit 60 per cent of the metal injected was fixed in the liver within fifteen minutes. Voight, in similar experiments, found that after three hours 81 per cent of the silver was fixed in the liver, and that none of it remained in the blood. It appears from these experiments that colloidal metals will not circulate in the blood and act there as a disinfectant for more than a few minutes.'
