Droterin-Ace is a combination drug for pain and muscle convulsions. Drotaverine is an antispasmodic and it works to relax the smooth muscles of the stomach and uterus; on the other hand, Aceclofenac acts as a strong anti-inflammatory medicine and painkiller. It is frequently used for abdominal pain, menstrual cramps, and some forms of constipation-colicky pains as well as being included in the griping-pain formulae for inflammatory conditions.
