Longs Drug Stores, the Walnut Creek-based drug retail chain, reported Wednesday that its profits soared a hefty 80 percent in the first quarter of 2008. According to the East Bay Business Times, Longs profits came in at $23.5 million, and the company is busy trying to buy back some of its public stock. Overall, the company expects revenue to rise between five and seven percent by the end of its fiscal year. Is it the Claritin? The Lipitor? Anyone hazard a guess as to which funky drugs put the store so deep in the black?
