  • Acute pain: 250 mg. two or three times a day
  • Severe cases: 500 mg. twice or three times a day

Chemical composition

Meftal Spas has two key ingredients: these are 250 mg of Mefenamic acid and 10 mg of Dicyclomine an anti-spasmodic. Dicyclomine is also called Dicycloverine. This is the composition of the 250 mg tablet. The 500mg tablet is called the Meftal Spas DS, which means it is of double strength. It has a composition of 500 mg of Mefenamic acid and 20 mg of Dicyclomine.

Mechanism of Action (MOA)

Inflammatory mediators are the chemicals behind the occurrence of fever, pain, and inflammation. Of these mediators, the most prominent are the prostaglandins such as the Thromboxane A2 and Prostacyclin. Other mediators include a number of leukotrienes. To produce these prostaglandins, enzymes are required to catalyze the reactions in their production. The last stage for their production requires Cyclooxygenase type 2.
The Mefenamic acid that is one of the major components of Meftal Spas Tablets works by blocking this final reaction thus preventing the formation of the prostaglandins.
The other component, Dicyclomine is an anticholinergic. It works by the relaxation of smooth muscles, like the stomach and gut muscles. It relieves pain, discomfort, and cramps by preventing sudden muscle contractions from taking place.
