Of the three, a tablet would be probably the most rapidly absorbed. It also depends on the type of medicine. Some can be fairly rapidly absorbed by the body.
Intravenous administration is usually the most rapid method. Nicotine is very rapidly absorbed by the lungs into the blood stream thence to the brain. I%26#039;ve never tried coke, but I%26#039;m told one feels it very shortly after snorting. Some medications given by rectal suppository are surprisingly rapidly absorbed. Likewise under the tongue, nitroglycerin for angina as an example. Intramuscular and subcutaneous injections are often surprisingly slow to be absorbed.
So, in rough general order of rapid absorption: intravenous %26gt; inhalation %26gt; rectal %26gt; sublingual %26gt; oral %26gt; IM %26gt; subq %26gt; transdermal, all with a lot of variation depending on the type of substance.|||Not too easy to answer. Some tablets are formulated to be either delayed release or slowly releasing, there are too few %26quot;rubbing cream%26quot; formulations to make a comparison, and patches are almost always intended as slow-release preparations. The answer is probably a regular tablet if the target is a proper blood level.
