Answer: Bulk-forming laxatives
Explanation:
Most laxatives that are available in the market are Bulk-forming laxatives and this is because they are first line laxatives before more serious laxatives are used. They prevent mild short term constipation and because they are so gentle on the body, are safe for use in the long term.
Bulk-forming laxatives work by absorbing liquid in the intestine thereby helping in bowel water retention such that the stool is softer, more liquid and therefore easier to pass.
What is the advantage of nitro patches?
Nitroglycerin transdermal patches (nitro patches) are used to prevent angina (chest pain) caused by narrowing of blood vessels in coronary artery disease (CAD). It does not work to relieve the pain of an angina attack that has already started. Nitroglycerin is a vasodilator; it works by relaxing the blood vessels (expanding the narrowed vessels) so that the heart does not need to work as hard.
