Critical Homecare Solutions Holdings has called off its initial public offering after agreeing to a takeover by MBF Healthcare Acquisition Corp., reports The Associated Press.

In a filing with the Securities and Exchange Commission, Critical Homecare, which provides patients with home intravenous drug services, asked to withdraw its registration statement for the proposed IPO.

Earlier this month, MBH agreed to acquire Critical Homecare's outstanding capital stock for $420 million. Critical Homecare is a portfolio company of private equity firm Kohlberg & Co.

Under terms of the deal, MBH will change its name to Critical Homecare Solutions Inc. The company's common stock will continue to trade on the American Stock Exchange.

The acquisition is expected to close in the second or third quarter of 2008, pending MBH stockholder approval and other customary closing conditions. The combined company will be led by Robert Cucuel, ceo of Critical Homecare.
