asked the Secretary of State for Social Services when he expects the panel of experts to conclude their investigation into the mechanism of the practolol (Eraldin) syndrome; and if there will be an interim report.

The panel has wide terms of reference on all beta-blocking agents, and I am advised that the studies into possible mechanisms of toxicity require detailed basic research and the monitoring of patients over long periods. These studies may take several years. The panel will give advice to the Chief Scientists of the Health Departments and the Committee on Safety of Medicines as it becomes available.
