What is Spasm Pain?

Spasm pain is related to muscles. When one or more muscles make the involuntary movement or forcibly contract, but cannot relax then it results in spasm pain. It may be caused by stress, infection, inflammation or any blockage. It is often referred to as cramps. Antispasmodic tablets act only as a relief in this case.

The antispasmodic uses of this drug are for:

• Menstrual pain

• Pain caused by a biliary stone
• Gastro-intestinal colicky pain

Mechanism of Action

Drotaverine HCL dosage inhibits phosphodiesterase hydrolysing cAMP (Cyclic Adenosine Monophosphate), which in turn increases the concentration of the cAMP. This decreases the calcium (Ca) uptake capacity of the cell resulting in a change of distribution of Ca among the various cells.

This antispasmodic drug blocks the allosteric calcium channel up to a certain extent. It has a high bioavailability variable, i.e. maximum portion of the drug enters into the circulation system of the body and works effectively. With a hepatic metabolism, INN has a half-life of 7 to 12 hours. (3)
