[Results of midodrin treatment of vasovagal syncope]
Aim:
To elicit efficacy of midodrin in patients with vasovagal syncope.
Material And Methods:
50 patients with recurrent vasovagal syncope documented by head-up tilt tests or bicycle exercise stress tests participated in the study. These tests controlled the effects of midodrin if syncopes occurred again in repetition of the tests. In the other patients the effect of the drug was assessed clinically. All the patients received midodrin in daily dose up to 15 mg.
Results:
Mirodrin effectively prevented syncope in 13 (72%) patients as shown by the tilt test, in 10 (59%) patients as shown by the exercise stress tests and in 14 (93%) patients as controlled clinically. Total efficacy of midodrin was 74% (37 of 50 patients).
Conclusion:
Midodrin demonstrated high efficacy in prevention of vasovagal syncope. Side effects were not serious therefore the drug is well tolerated.

Cholinergic Antagonists: Therapeutic Uses
Respiratory Tract: Ipratropium, aclidinium, and tiotropium treat asthma, chronic bronchitis, and chronic obstructive pulmonary disease (COPD). They protect against bronchoconstriction caused by irritants like cigarette smoke, sulfur dioxide, and ozone. They also help reduce nasopharyngeal secretions in common...

Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
