How route of administration drug can control bioavailability drug?
biovability of intral nasal route
Can a drug which is 100 percent absorbed from GI tract have 100 percent bioavailability?
yes
How does chemical stability of the drugs in the gastrointestinal tact affect the bio-availability of the drugs?
Bioavailability is used to describe the fraction of an administered dose of unchanged drug that reaches the systemic circulation, so we need chemically stable drug in order to increase the chance of drug absorbance and thus increased bioavailability.
What is mineral bioavailability?
The proportion of the mineral that can be utilised
Is the bioavailability of calcium in calcium-fortied orange juice comparable to that of milk?
Calcium is calcium. Your body doesn't know or care if it came from milk, orange juice, or chalk however the presence of vitamin D appears to help with absorption.
What is bioavailability?
Bioavailability is the amount of drug which reaches the site of physiological activity after administration.
What is a bioequivalence?
A bioequivalent is a formulation of a drug which is equivalent to some other formulation in terms of bioavailability.
How route of administration drug can control bioavailability drug?
biovability of intral nasal route
Bio availabilty has a better feature when it gets dissolved or undissolved?
Bioavailability measures the amount of a drug (medicinal) or other substance which enters the blood. This depends on two types of factors: 1) The physical and chemical properties of the drug. If a drug is insoluble (ie does not dissolve) in the stomach or intestine it is unlikely to be absorbed into the blood, so its bioavailability will be low. If it is soluble it is more likely to be absorbed so its bioavailability will be high. 2) The route in which it is given. Direct injection into the blood gives 100% bioavailability. Taking a drug by mouth is likely to give less than 100% bioavailability. For more details see: http://www.merck.com/mmpe/sec20/ch303/ch303c.html

What is the medical term meaning extent to which a drug or other substance becomes available to the body?
Bioavailability
What is bioenhancer?
A bioenhancer is a biological enhancer - any naturally-occurring compound which increases drug bioavailability.

What factors determine a drug's rate of metabolism?
How quickly a drug clears from the body is a function of its absorption, bioavailability, distribution, metabolism, and excretion properties.
Why is a pharmaceutical equivalent not necessarily therapeutically equivalent?
They can still have different bioavailability (the amount of drug that is delivered to the site of action and the rate at whcih it is available). Pharmacetical equivalents do not have to have the same release mechanisms, and can therefore affect their bioavailability.
What is bioavilability in pharmacology?
Bioavailability in pharmacology refers to the fraction of a drug that reaches the systemic circulation and is available to produce an effect after administration. It is typically expressed as a percentage and takes into account how much of the administered dose is absorbed and becomes available to the body. Factors like drug formulation, route of administration, and first-pass metabolism can affect a drug's bioavailability.
