Phenytoin can be a difficult drug to use for the following reasons. Phenytoin is extensively bound to plasma albumin and other drugs such as salicylates and valproate displace it from its binding site. However, this does not necessarily lead to increased drug activity because metabolism of increased amounts of free drug is also enhanced. Thus, phenytoin may show increased or decreased activity. Other drugs, for example phenobarbital, compete for the same liver enzymes.

This can occur by conjugation between two bacteria or by viral transduction. Resistance to antibiotics can develop by the following mechanisms: enzymes produced by bacteria destroy the drug; the bacterial cell wall becomes impermeable to a drug or the drug is rapidly removed; drug binding sites within bacteria become altered; alternative metabolic pathways develop in bacteria using enzymes not affected by the drug. The development of resistance can be reduced by less indiscriminate use of antibiotics, using them only where there is a distinct clinical need and ensuring that patients complete the entire course of antibiotics. This reduces the risk of survival and reproduction of resistant strains.

To minimize side effects the maintenance dose of prednisolone should be kept as low as possible. In moderate to severe rheumatoid arthritis of less than two years duration, low dose prednisolone may reduce the rate of joint destruction. Nevertheless, it is recommended that maintenance therapy should be for two to four years only and then gradually reduced to avoid possible long-term adverse effects.

The rate of absorption depends on the usual parameters for passage across cell membranes but also on the blood or lymphatic supply to a particular region. Increasing the blood supply by applying heat or massage will increase the rate of absorption. Conversely, for a local effect, addition of a vasoconstrictor to the injection decreases the rate of removal of the drug from the site of injection. Depot preparations are designed to give a slow sustained release of drug. Drugs injected intravenously go directly into the blood stream and are rapidly distributed around the body.
