ABSTRACT
Nowadays NSAIDs are the most frequently used groups of drugs, especially because of their availability. Their consumption is high among older people, who are much more sensitive to the side effects, and who are often also taking other drugs which can interact with them. Moreover, the majority of the older population is suffering from hypertension. This could well explain the commonly encountered experience of drug interaction between NSAIDs and antihypertensive drugs, which is very common in clinical practice. The severity of this drug interaction is classified as class C, with a recommendation to monitor therapy. However, even a minor long-term increase in blood pressure can significantly increase the risk of cardiovascular mortality, while mortality rates can possibly be reduced by sufficiently effective treatment of hypertension. Therefore, in clinical practice, this type of interaction should not be overlooked as a major cause of failure of hypertension treatment in older patients, as well in many cases in general. The present article focusses on the mechanism and the degree of influence on the blood pressure of particular types of antihypertensive agents used in combination with NSAID. Not all groups of antihypertensive drugs are affected to the same degree; some are more affected, and others, such as calcium channel blockers, are not affected at all. Similarly, not every NSAID increases blood pressure. Many studies, some of which are analyzed in this article, present evidence of the degree of the influence NSAIDs have on blood pressure.
