asked the Secretary of State for Social Services if he will estimate the costs per annum to the National Health Service of purchasing cyclosporin; if he will detail the current uses of this drug in the National Health Service; and if he will make a statement.

We do not usually give details of the sales of any drug as this information is regarded as confidential because of its commercial value. The current uses of cyclosporin include prevention of graft rejection following bone marrow, kidney, liver, pancreas, heart and heart-lung transplantation and prophylaxis of graft-versus-host disease.
