Valeant Pharmaceuticals International has appointed Howard Schiller interim chief executive officer of Valeant, effective immediately.

Valeant also announced that Robert Ingram, lead independent director, will serve as interim chairman of the board of directors.

J. Michael Pearson remains in the hospital, where he is being treated for severe pneumonia, and as the timing of his expected return is uncertain, he will be on a medical leave of absence until further notice.

Ingram said, "As Mike's medical leave continues, and the timing of his recovery and return remains uncertain, Howard will now step in as CEO on an interim basis. Howard's performance as Valeant's CFO, as well as his deep understanding of Valeant's operations, are excellent and we are grateful that he has agreed to take on this role. The board will continue to work closely with Howard and the other members of the senior management team to implement Valeant's strategy successfully in Mike's absence."
