First came its acquisition of Take Care Health Systems. Then, an announcement that Walgreen Company (NYSE: WAG) was planning to acquire Option Care, Inc (NASDAQ: OPTN). Next...?

Bank of America analysts are speculating that geriatric pharmaceutical services company Omnicare, Inc (NYSE: OCR) could eventually be on Walgreens' acquisition radar.

Walgreens acquired Take Care and is planning to acquire specialty pharmacy services provider Option Care in an effort to grow its health care operations and to provide patient-focused health care services. Walgreens has estimated the market for these operations is around $60 billion a year and has a projected annual growth rate of 20%. Analysts believe that for this very reason, Walgreens take a closer look or two at Omnicare, which provides its pharmacy services to long-term care and chronic-care facilities in 47 states throughout the U.S.

Omnicare recently began legal proceedings against 16 drug benefit plans and health insurers, after alleging it has been burdened with "inappropriate" co-payments and rejected payment claims; the company is seeking to collect $61 million it believes is due. The analysts believe Walgreens won't show interest in Omnicare unless it retains its leading market share in the institutional pharmacy sector while addressing pertinent issues like balance sheet challenges and cost structure. Should these legal issues clear, Walgreens may ultimately find Omnicare more attractive.
