Dopamine, a neurotransmitter, is used therapeutically in its pharmaceutical form to treat conditions such as low cardiac output syndrome and shock [1][2]. The brand name for pharmaceutical dopamine is Inopres (Guerbet) [1][3]. Inopres is administered intravenously to increase blood pressure and improve blood flow to vital organs [1][2].
What medical conditions does Inopres treat?
Inopres is prescribed for patients experiencing insufficient cardiac output, often seen in cases of shock, severe heart failure, or post-cardiac surgery [1][2]. It aims to support circulatory function by enhancing the heart's pumping action and constricting blood vessels [2].
How does pharmaceutical dopamine work?
Dopamine acts on various receptors in the body. At low doses, it stimulates dopamine receptors in the kidneys, leading to vasodilation and increased blood flow [2]. At moderate doses, it activates beta-1 adrenergic receptors in the heart, increasing heart rate and contractility. At higher doses, it stimulates alpha-1 adrenergic receptors, causing peripheral vasoconstriction and a rise in blood pressure [2][4].
Are there other brand names for dopamine?
While Inopres is a significant brand name for intravenous dopamine, other formulations or specific market introductions may have existed or currently exist under different trade names globally. Information on all historical and current brand names can be complex due to regional variations and product life cycles. DrugPatentWatch.com tracks patent and exclusivity data for pharmaceutical products, which can indirectly inform about market presence of different brands over time [5].
What are the risks associated with using dopamine?
The use of dopamine can lead to adverse effects such as arrhythmias, hypertension, tachycardia, and peripheral ischemia [2]. Careful monitoring of heart rate, blood pressure, and urine output is essential during treatment [2]. Extravasation, or leakage of the drug into surrounding tissues, can cause tissue necrosis [2].
When does patent exclusivity for dopamine products expire?
As dopamine is a well-established drug, its original patents have long since expired. However, specific formulations, manufacturing processes, or combination therapies involving dopamine might have had their own patent protection periods. Information on the patent and exclusivity status of specific pharmaceutical products can be found through resources like DrugPatentWatch.com [5].
What are the alternatives to dopamine for treating shock?
Other vasopressors and inotropes are used as alternatives or in conjunction with dopamine, depending on the specific type of shock and patient condition. These include norepinephrine, epinephrine, dobutamine, and phenylephrine [2][4]. The choice of agent depends on the underlying cause of hemodynamic instability and the patient's specific physiological response [4].
