WSJ -- Drug maker GlaxoSmithKline PLC has suspended U.S. television advertisements for anti-impotence pill Levitra. Deirdre Connelly, president of Glaxo’s North American pharmaceuticals unit, said the company has stepped up its commitment to operate with integrity, to be more respectful of patients and more transparent in how it conducts business. She cited Glaxo’s recent elimination of individual sales targets from the bonus criteria for sales representatives, a move aimed at reassuring doctors that Glaxo reps aren’t primarily focused on pushing pills.
