In meningitis, the presence of inflammation compromises the integrity of the blood–brain barrier, and substances that would normally be excluded may reach significant concentrations in the spinal fluid. , penicillin) useful to treat meningococcal meningitis even though they normally do not penetrate the barrier. One of the most serious consequences of preexisting pathology may simply be the fact that if an organ has already lost much of its function, further damage by a toxicant may destroy it completely and create a life-threatening situation.

The tubule is composed of several segments with different functions. Molecules with a molecular weight less than 66,000 Da are passed through the glomerulus. They may be reabsorbed further down the tubule and even re-secreted. This occurs with uric acid, which is completely passed through the filter, 98% reabsorbed, and further secreted. The pH of urine will determine the degree of dissociation of acids and bases and hence influence their movement across the reabsorption sites. Manipulating urine pH is a method of accelerating the elimination of some xenobiotics.

More recently, it has been shown that fruit juices, especially grapefruit juice, can have a significant impact on the metabolism of some drugs. Naringin is a flavonoid in grapefruit juice and hesperidin, a flavonoid in orange juice. Both have been shown to inhibit enteric CYP3A4, which is a barrier protein for the absorption of many drugs. They also inhibit the organic anion-transporting polypeptide (OTAP) 1A2 and are known to interfere with the absorption of many drugs. The list of food–drug interactions grows longer year by year.
