ABSTRACT

There are certain groups of drugs which are known to cause airways narrowing in everyone. These should be avoided in all asthmatics. In addition, there are some which may cause asthma attacks only in certain allergic individuals. Examples of the first group of drugs (which include propranolol) are non-selective beta blockers, which may be prescribed for conditions such as hypertension, angina, anxiety and occasionally migraine (beta blocker eyedrops are also contraindicated).
