The prevalence of psychiatric disturbances in patients with cardiovascular disease is elevated. For example the prevalence of major depression can reach 15–20% and of anxiety disturbances 5–20%.

When we treat psychiatric symptoms in cardiovascular disease we must have in mind four particular effects of psychiatric drugs: (1) disturbances of atrial-ventricular conduction; (2) QTc interval prolongation that can lead to torsade de pointes and ventricular fibrillation; (3) hypertension; (4) changes in platelet aggregation.

On the other hand, there is a great prevalence of psychiatric disease in patients with renal disease. For example, about 5–25% of the patients with advanced renal disease have major depression.

Renal disease patients can evidence changes in several pharmacokinetic parameters such as: (1) biodisponibility; (2) distribution; (3) metabolism; (4) excretion. Therefore, when we treat these patients we have to keep in mind the effect of psychiatric drugs over the renal functioning, but also the effect of the deficient renal function in the pharmacokinetics of the drugs.

I this presentation we intend to reveal what are the main concerns when we prescribe psychiatric drugs in patients with cardiovascular and renal disease.
