However, many drugs are much more potent taken sublingually, and it is generally a safer alternative than administration via the nasal mucosa. [ citation needed ] This method is also extensively used by people administering certain psychoactive drugs.
In pharmacology and toxicology, a route of administration is the way by which a drug, fluid, poison, or other substance is taken into the body. [1] Routes of administration are generally classified by the location at which the substance is applied. Common examples include oral and intravenous administration. Routes can also be classified based ...
Thin-film drug delivery uses a dissolving film or oral drug strip to administer drugs via absorption in the mouth (buccally or sublingually) and/or via the small intestines (enterically). A film is prepared using hydrophilic polymers that rapidly dissolves on the tongue or buccal cavity, delivering the drug to the systemic circulation via ...
A tablet can be formulated to deliver an accurate dosage to a specific site in the body; it is usually taken orally, but can be administered sublingually, buccally, rectally or intravaginally. The tablet is just one of the many forms that an oral drug can take such as syrups, elixirs, suspensions, and emulsions.
Drugs given by enteral administration may be subjected to significant first pass metabolism, and therefore, the amount of drug entering the systemic circulation following administration may vary significantly for different individuals and drugs. Rectal administration is not subject to extensive first pass metabolism.
Systemic administration is a route of administration of medication, nutrition or other substance into the circulatory system so that the entire body is affected. [1] Administration can take place via enteral administration (absorption of the drug through the gastrointestinal tract) [ 2 ] or parenteral administration (generally injection ...
[165] [166] [163] [164] In one study, which administered a mean total dosage of sublingual estradiol of 4.8 mg/day, estradiol levels remained elevated at about 130 pg/mL on average in the morning before the first dose of the day. [165] Oral micronized estradiol valerate tablets can be taken sublingually as well.
While it has a less permeable effect than sublingual administration, buccal administration is still capable of creating local or systemic effects following drug administration. [7] In the oral cavity, buccal tablets potentiate their effect by entering the bloodstream direction through the internal jugular vein into the superior vena cava , [ 8 ...
