Many people all over the world take medicine from time to time. Many people take nutritional vitamins supplements on a regular basis. Many people even take herbal medicines and that type of thing on a regular basis. Each one of these things will have a specific level of bioavailability. This really is something which most people do not know, in fact, many people do not even think about it. Let's take a look at exactly what bioavailability is and what factors affect it.
The word bioavailability is used to describe the amount of an administered drug is available for use in your body. It'll change from individual to individual and also from medication to drug and is also dependant on how the drug is administered. The more indirectly the drug is administered the more its bioavailability will reduce. It is actually a really important factor to take into consideration with regards to calculating how much of a drug to give to an individual when it comes to administering drugs non-intravenously.
Bioavailability is measured as a percentage. A medication that's administered intravenously has a 1005 bioavailability and this is actually expressed as a value of 1. If you take the medication by mouth or by way of absorption through the skin then the bioavailability of the medication will be some thing less than one because not every one of the actual drug is going to be soaked up or made available for use in the body.
It is because of this bioavailability component that some drugs are to be taken on an empty stomach while some have to be taken with food. A few medicines react differently with certain kinds of meals and this will additionally impact how well it is absorbed into the actual bloodstream. It is also impacted by the other medicines that you might take in addition to a specific drug. It's also impacted by the actual micro flora in your intestines and your personal intestinal motility. Even particular ailments that affect your liver and intestinal functions will have an effect on the bioavailability of any medication that you take. The physical properties of the drug will affect its bioavailability. How the medication responds to enzymes will affect how well it can make itself available to your body. Even your age and how quick your metabolism is will affect how quickly and well the drug is absorbed. It seems as though all things biological may affect the bioavailability of the medication.
It is because of all these factors that it's very difficult to calculate the actual bioavailability of a drug with accuracy. This is generally not too much of a problem though. You can get a general idea of what to anticipate by taking a look at the area underneath the curve of the graph for the absorption rate for the specific medication you want to administer. If you wish to be certain of how much of a medication your patient is getting the best thing to do would be to administer the medication intravenously. Apart from that, a good estimation is usually sufficient.
