The scientists are trying to fight the arterial hypertension, therefore, there are many of the drugs designed for treatment of this disease. The patient can choose the drug depending only on disease and health state. One of the most effective and popular drugs for arterial hypertension treatment is Atenolol.
Clinical researches have proved the high values of the drug effectiveness. Atenolol is a selective beta-adrenoreceptor blocker in the muscular walls of the heart resulting in low pulsation, reduces myocardial contractility leading to decrease in requirement of myocardial oxygen, thence, in reduction of stenocardia attacks. It renders antiarrhythmic action, due to reduction sinus rhythm, decrease in myocardial excitability and AV-conductivity delay. After Atenolol taking, the risk of hypertensive crises and other cardiovascular diseases decreases in the patient.
Also it has been revealed that after Atenolol use, the number of the survived patients after heart attack is increased, the drug reduces frequency of ventricular arrhythmia and stenocardia development. If administered in standard therapeutic doses, the drug has less expressed effect on: pancreas, skeletal muscles, smooth muscles of peripheral arteries, bronchial tubes and uterus. The safety of the drug is increased.

Pulmonary embolism is an acute arterial occlusion of pulmonary artery branches by embolus, separated from the thrombus in the big blood circulation veins. In spite of many modern drugs for pulmonary embolism prophylaxis, the number of the patients with this pathology is increased for last decades. The high risk of pulmonary embolism is related to the following diseases: cardiac insufficiency, cardiac infarction, stroke, nephrotic syndrome, polycythemia, system red lupus. The highest risk of development of pulmonary embolism is observed after surgical interventions within 2 weeks. However, if we consider the modern treatment of this disease, we can say that medicine is able to prevent and to treat the problem. Medications have been developed to help in pulmonary arterial hypertension treatment. One of these drugs is Revatio.
