The word "antemetick" is not a standard word in English. However, if we break down the spelling using IPA phonetic transcription, we can understand it better. "Ante-" means "before" or "prior to". "Metic" is the IPA pronunciation for "emetic", which means "causing vomiting". Therefore, "antemetick" likely means "a substance taken before an emetic to prevent vomiting". However, it should be noted that this spelling is not commonly used and may cause confusion.
