Isosorbide dinitrate stimulates the formation of nitric oxide in the body and reduces the needs of the heart muscle in oxygen and energy, thereby reducing the burden on the myocardium. It effectively reduces pressure in a small circle of blood circulation, weakens the blood flow to the right atrium, reduces the stress of the walls of the cardiac ventricles, decreasing diastolic pressure and improving the systolic function in them. The drug has no effect on the frequency of cardiac contractions and extends well the cerebral vessels. It can also increase the vessels of the dura mater and the brain itself, thereby causing pain in the head.

The agent influences the redistribution of the coronaryblood flow in the area where blood circulation is reduced. With IHD (ischemic heart disease) and angina due to the drug in patients, it becomes possible to increase the permissible physical loads.

Spray "Izoket" quickly absorbed throughout the areamucous membrane of the mouth, so the effect of its use comes after 30 seconds and lasts up to 120 minutes. Due to its speed, it is often prescribed to patients for relief of acute acute conditions.

Special recommendations on the use of a spray

In cases where a new aerosol is usedFor the first time, or after the last intake, more than 24 hours have passed, it is recommended that the first push be directed into the air, since it may not contain the required dosage.

• pronounced hypotension, at which the systolic pressure drops below 90 mm Hg;
• vascular insufficiency in the acute stage, for example, with shock or vascular collapse;
• pericarditis and pericardial tamponade;
• at a cardiogenic shock in cases when there is no possibility to correct in another way pressure in the left cardiac ventricle;

Pregnancy and lactation

Scientists in the development of the drug were carried out animal studies. Experiment on the subjects showed that the damaging effect on the fetus is not performed.

However, during pregnancy and lactationperiod, the appointment of an aerosol is recommended only in those situations where the intended use for a woman will significantly exceed the potential risk to the fetus or infant.

Interaction with other medicines

Sharing is prohibited.vasodilators and the drug "Izoket" (spray). Applying them in combination can cause an increase in the hypotensive effect. The same consequence entails the simultaneous administration of Isoket aerosol and such medications: antihypertensive agents, calcium channel blockers, quinidine or Novokainamide, neuroleptics, phosphodiesterase-5 inhibitors.

It is possible to increase the antianginal effect withuse in conjunction with drugs such as Amiodarone, Propranolol, Nifedipine, Verapamil, and with other calcium delayed channel blockers.

Increased intracranial pressure in the patient may occur with combined therapy with atropine and other m-holinoblokatorami.

Excessive reduction in blood pressure, leading to coronary perfusion, appears under the influence of alpha-adrenoblockers and sympathomimetics.

Side effects and reviews

The manual describes a lot of side effects,which can be caused by the drug "Isoket" (spray). Reviews of some patients taking this medication indicate the appearance of headaches, which in medicine are called "nitrate".
