This document summarizes several medical devices used to deliver drugs. It describes the insulin pen as providing more accurate dosing and convenient insulin delivery, with hypoglycemia as an adverse effect of insulin. Transdermal patches are described as delivering nitroglycerine and hyoscine with prolonged duration of action and bypassing first pass metabolism. Intravenous drips and canulas are said to deliver drugs like dopamine and sodium nitroprusside rapidly through intravenous routes in emergency situations with 100% bioavailability and suitability for unconscious patients. Nebulizers deliver salbutamol, ipratropium bromide and budesonide directly to the lungs without requiring synchronization with breathing to maximize lung delivery. Metered dose inhal
