3. Volunteers whose clinical laboratory test values outside the accepted reference range and when confirmed on re-examination is deemed to be clinically significant.
4. Volunteers who demonstrate a reactive screen for hepatitis B surface antigen, hepatitis C antibody, or HIV antibody.
5. Volunteers who report a history of allergic response(s) to propranolol or related drugs.
