Document Summary

But produces stomach discomfort due to its acidity. The addition of the acetyl group allows it to pass unchanged through the stomach and finally into the bloodstream where it can go into action. Prostaglandins (pge2) hormone that controls growth and other tissue changes and regulates a variety of physiological responses such as inflammation, fever, pain. First step to make pge2 is to make cyclo-oxygenase which is inhibited by aspirin which inhibits the production of prostaglandin. Can be modified like aspirin by introducing acetylate. Less polar than morphine (i. e. crosses the blood-brain barrier more rapidly) First thought to be a non-addictive morphine substitute and cough suppressant. Relieves cold symptoms and allergic reactions to pollen. Dimetapp binds to histamine receptors in the nasal cavity to reduce swelling and prevent the allergic reaction. Binds to the receptors that trigger acid release in the stomach reducing irritation to inflamed stomach lining. The ability of microorganisms to withstand the effects of an antibiotic.
