What is Primacor? Primacor is a milrinone IV infusion solution used to treat congestive heart failure and cardiac arrest. It works by increasing the strength of the heart's contractions and improving blood flow [1]. The drug is usually administered through a drip, hence the name Primacor drip. Mechanism of Action Milrinone, the active ingredient in Primacor, is a phosphodiesterase inhibitor that increases the levels of cyclic AMP (cAMP) in the heart. This leads to an increase in the contractility of the heart muscle, allowing the heart to pump blood more efficiently [2]. Indications and Uses Primacor is indicated for the treatment of congestive heart failure and severe cardiac failure. It is often used in situations where other treatments have failed or are not effective. The drug can be used in both acute and chronic heart failure cases [3]. Administration and Dosage Primacor is typically administered as an IV infusion solution at a dose of 50 mcg/kg/min to 200 mcg/kg/min. The infusion rate can be adjusted based on the patient's response and heart function [4]. Potential Side Effects and Risks Common side effects of Primacor include headache, nausea, and vomiting. More serious side effects can include rapid heart rate, palpitations, and low blood pressure. It is essential to monitor the patient's heart function and vital signs closely during infusion [5]. Regulatory Status and Exclusivity Primacor was approved by the FDA in 1993. The patent for milrinone expired in 2002, making the generic version of the drug available in the market [6]. Several generic versions of milrinone are available in the US, including those from pharmaceutical companies such as Mylan and Teva.
