However, a major problem with MAOI drugs is that they produce a number of potentially fatal interactions with other drugs and common foods.

At extremes of life absorption, distribution, metabolism and excretion can all be different to normal so that drug action becomes unpredictable.

Contrast agents are used to enhance radiological examination of the body. Although air and gas can be used to provide negative contrast, positive contrast agents are most commonly used. These are based on iodine or barium molecules which absorb X-rays well. Development of intravenous buy 100mg tramadol contrast agents has a relatively long history, going back to the benzene rings.

The antihypertensive effect of β-blockers is not completely understood. A decrease in heart rate and force of contraction would reduce cardiac output, but this is likely to be compensated for by the baroreceptor reflex. It is possible that β-blockers work, at least partially, by some central action in the cardiovascular control centres of the brain. β-blockers also block receptors in the peripheral blood vessels, kidney and bronchi.
