The word "amygdophenin" is a complex term that may be difficult to spell without breaking down its components. The first segment, "amygdo-", refers to the amygdala, a part of the brain associated with emotion and fear. The second segment, "-phenin", is a suffix used in the names of various chemical compounds. When pronounced, the stress falls on the second syllable, with the "g" and "d" sounds merging into a voiced velar nasal (/ŋ/) sound. The IPA phonetic transcription is /əˌmɪɡdoʊˈfiːnɪn/.
Phenetidin amygdalate; a compound of para-amidophenol and mandelic (amygdalic) acid; occurs in white slightly soluble crystals; recommended in neuralgia and rheumatism in doses of gr. 7 1/2-15 (0.5-1.0).
