The pronunciation of this word is "ahb-STI-puhnt", with the emphasis on the second syllable. The letters "st" in the middle of the word can be confusing, but they are pronounced as a cluster, similar to the way they are pronounced in the word "mystify". "Obstipant" is an adjective used to describe a substance or condition that causes constipation.
