SPASMOSAFE
- Drotaverine HCL is an iso-quinoline derivative, which has
spasmolytic action on smooth muscle of the coronary, peripheral
arteries, and uro-genital tract.
- Its action is due to surface activity by binding to the surface of
smooth muscle. It acts by elevation of CAMP level, through
phosphodiesterase inhibition, it normalizes the smooth muscle
tone bringing the hypertonic state to a normatonic state.
- Drotaverine HCL is better tolerated by humans, it has
spasmolytic action stronger than papaverine. Its protein binding
is lower, its effect develops more rapidly, slowly released and
last longer than that at papaverine and perparine.
- The absorption of Drotaverine HCL is extremely rapid. within
12 minutes
- The peak plasma levels reach between 45 and 60 minutes
indicating rapid absorption.
- The half life of Drotaverine HCL is 6 hours, regardless the route
of administration.
- Drotaverine HCL is metabolized by the liver and excreted in the
bile (50%) & urine (30%). The elimination of Drotaverine is
practically completed within 72 hours.
