Bioequivalent products are expected to be therapeutically equivalent. Sometimes these factors vary based on the metabolism and enzyme levels a specific person has in their body compared to others. Advertising revenue supports our not-for-profit mission. Project CBD. Many people assume that inhaling cannabis, whether smoking or vaporizing gives your body the same amount of THC, but this simply is not true. When it comes to joints, they typically contain. Bioavailability, defined as the ratio of the areas under the blood concentration-time curves, after extra- and intravascular drug administration corrected for dosage if click the following articleis often used as a measure of the extent of first-pass metabolism.
Abstract First-pass elimination takes place when a drug is metabolised between its site of administration and the site of sampling for measurement of drug concentration. In earlier studies, when a 3. When several sites of first-pass metabolism are in series, the bioavailability is the product explain first pass metabolism method calculator the fractions of drug entering the explain first pass metabolism method calculator that escape loss at each site. Products and services. The accidental discovery of the tomb of a Tang click here soldier, Guo Xing, hinted at cannabis as an important food crop in ancient China.

Error Include a valid email explain first pass metabolism method calculator. Bioavailability refers explain first pass metabolism method calculator the extent and rate at which the active moiety drug or metabolite enters systemic circulation, thereby accessing the site of action. You've probably heard people blame their weight on a slow metabolism, but what does that mean?
Find out how metabolism affects weight, the truth behind slow metabolism and how to burn more calories. Test your knowledge. Clinical chemistry57 166— Rectal use was shown to absorb in the body quicker and bioavailability was higher because it was absorbed rectally at higher levels and had a lower first-pass metabolism.

One dose that works great for a friend may explain first pass metabolism method calculator too large or small for you because of this.
One may wonder what these are used for. Keep in mind, using a suppository gives you local pain relief, as opposed to other delivery methods where THC passes into the blood 3. Thus overall bioavailability of THC used as a suppository has no rectal bioavailability. In fact, a study focusing on rectal use in rhesus monkeys found that THC was not bioavailable after testing blood plasma levels This was compared to oral and intravenous, and intramuscular cannabis delivery methods. One study focused on administering Marinol rectally. Marinol, a synthetic THC medication, has been approved by the FDA and is primarily used for uncontrolled nausea during chemotherapy in cancer patients. This study on Marinol for spasticity concluded that rectal administration of 2. Researchers found that rectal bioavailability of the was approximately twice that of using Marinol orally.
Rectal use was shown to absorb in the body quicker and bioavailability was higher because it was absorbed rectally at higher levels and had a lower first-pass metabolism. Lower first-pass metabolism is important because more of the medication is bioavailable for the body to use. It is important to explain first pass metabolism method calculator that this could be due to the fact that Marinol is not real THC, just synthetic. THC-HS rectal use can result in improvements in spasticity, rigidity, and pain while producing any other measurable signs of intoxication.
This bioavailability measurement was two-and-a-half times higher than levels after an orally ingested THC capsule. It article source important to again reiterate, that THC has no bioavailability when used rectally unless it has been altered. We also do not know how bioavailable THC or CBD is when used in suppositories vaginally, though there are studies underway to change that knowledge 3. Topical and transdermal products work to help relieve pain and inflammation transcutaneously, or through the skin 5.
This is because they are repelled easily by water, which allows them to transport easily across the aqueous layer of the skin. While there have been no human-based studies on the bioavailability of cannabinoids through a topical or transdermal application, the preclinical animal studies are promising. These application methods avoid a first-pass metabolism effect and through slow-release, they offer dosing over a longer period of time in comparison to other delivery methods. It is unlikely to feel psychoactive effects of cannabis when applying it to the skin. More research is needed on determining the true bioavailability of topical products. Available cannabis-based topicals include 2 :. A study evaluated the efficacy of transdermal CBD for reducing pain and inflammation in arthritic rat models. Researchers applied CBD gel doses of 3. They found that topical CBD gel in the larger doses improved arthritic symptoms in the rats and that it has a strong therapeutic potential for humans suffering from similar issues 4.
When it comes to using transdermal patches, researchers hope that it can reduce the negative side effects of cannabis use seen while smoking. They also believe that transdermal patches bypass the first-pass metabolism of cannabinoids which can help improve the effectiveness of the transdermal patch being used 5. Anecdotally many users experience stronger and longer-lasting joint and muscle pain explain first pass metabolism method calculator while using transdermal patches over topical products, but also this may depend on the amounts of THC and CBD in each of the products.

Peak time when maximum plasma drug concentration occurs is the most widely used general index of absorption rate; the slower the absorption, the later the peak time. For drugs excreted primarily unchanged in urine, bioavailability can be estimated by measuring the total amount of drug excreted after a single dose. Ideally, urine is collected over a period of 7 to 10 elimination half-lives for complete urinary recovery of the absorbed drug.
After multiple dosing, bioavailability may be estimated by measuring unchanged drug recovered from urine over a hour period under steady-state conditions.
