What Does The Suffix "ac" Mean In Medical Terms?

Can anyone name the five rules given for adding vowel suffixes ...

 
This website should help. I went to school for medical transcription and could give you the answer but I don't do others homework. Good luck.
Peace

In medical terminology ac translates exactly to ante cebos. That means before meals. A related term "pc" post cebos means after meals. Both terms are used when prescribing medications and when they should be taken. The best source of this information is your pharmacist. When you get a prescription filled, ask the pharmacist when is the best time to take your medications in regard to your meals. Some medications must be taken on an empty stomach, while others should only be taken after you eat. The reasons for the differences are to lengthy to list here, but your pharmacist can answer that for each medication you take.  

It means a person who has the sickness like hypochondriac has hypochondria or insomniac has insomnia
