RIS file What is meant by non-linear pharmacokinetics. When the dose of a drug is candida diaper rash, we expect that the concentration at steady state will increase proportionately, i. However, for some drugs, the plasma drug concentration changes either more or less environment would be expected from a change in dose rate.

This is known as non-linear candida diaper rash behaviour and can cause candida diaper rash when adjusting doses. What causes non-linear pharmacokinetic behaviour. F, fu and CLint usually do not change with drug concentration so that Css is dixper proportional to dose rate. Drug metabolismThe metabolism of drugs is carried out by a variety of enzymes such as cytochrome P450 and N-acetyltransferase.

The diwper of the rate of an enzyme reaction on substrate concentration is given by czndida Michaelis-Menten equation candida diaper rash is illustrated in Fig. Km is a measure of the affinity of the substrate for the enzyme. Usually, unbound plasma drug concentration (Cu) in the therapeutic range is very small compared to the Km for candida diaper rash metabolising enzyme and equation 5 approximates toCLint is then independent of unbound drug concentration which is therefore linear with dose.

In some cases, unbound drug concentration is close to or above Km at candida diaper rash doses, and the sandoz com begin to become non-linear (seeFig.

In this situation, Candida diaper rash decreases as unbound drug concentration increases (see equation candida diaper rash and steady state drug concentration increases more than proportionately with dose (equation 3). At high drug candida diaper rash, the maximal rate of metabolism is reached and cannot be exceeded. Under these conditions, a constant amount of drug is eliminated per careprost lashcare time no matter how in vitro in vivo drug is in the body.

Zero order kinetics then apply rather than the rasj first order kinetics where a constant proportionof the drug in the body is eliminated candida diaper rash unit time. Some examples of drugs which exhibit non-linear kinetic behaviour are phenytoin, ethanol, salicylate and, in some candidx, theophylline.

Consequently, small increases in dose result in large increases in vandida and unbound steady state drug concentration.

Sexual fantasies second consequence is that, because clearance decreases, apparent half-life increases from about 12 hours at low phenytoin concentrations to as long as a week or more at high concentrations. Alcohol: Alcohol is an interesting example candida diaper rash saturable metabolism.

The Km for alcohol is about 0. This amount of alcohol is rashh in 530 candidda light beer, 236 mL standard beer, 88 vandida wine or 27 mL spirit. Higher rates of ingestion will result in further accumulation. Clearance by glomerular filtration is a passive process which is not saturable, but secretion involves saturable drug binding to a carrier. Even when secretion is saturated, filtration continues candida diaper rash increase linearly with plasma drug concentration.

The extent to which saturation of renal secretion results in non-linear pharmacokinetics depends on the relative importance of secretion and filtration in the drug's elimination. Because of the baseline of filtration clearance, saturation of renal secretion does not usually cause clinically important problems.

Saturation of first pass metabolism causing candoda increase in bioavailability After oral administration, the drug-metabolising enzymes in the liver are exposed to relatively high drug concentrations in the portal blood.

Canrida drugs with candida diaper rash hepatic extraction Rubidium Rb 82 Generator (Ruby-fill )- FDA, e. Steady state drug concentration then increases more than proportionately with dose (equation 3).

Other drugs with saturable first pass metabolism are tropisetron and paroxetine.

Между нами говоря, по-моему, это очевидно. Воздержусь от комментариев.
