Tavera Uses, Dosage, Side Effects, Food Interaction and all others data.
Tavera has antispasmodic effect mediated via inhibition of phosphodiesterase-IV, specific for smooth muscle. It has a rapid and direct action on the smooth muscle. It acts to correct cyclic AMP and Ca imbalance at the spastic site, thereby relieving smooth muscle spasm and pain.
Tavera is an e spasmolytic agent with a relaxing effect on smooth muscles. It works to relieve visceral spasms and improve cervical dilation. In vitro, drotaverine mediated cytostatic effects on several human tumor cell lines and nonmalignant mouse fibroblasts. Tavera may have minor allosteric calcium channel blocking properties: in vitro, drotaverine behaves like voltage-dependent L-type calcium channel blockers.[A231624]

How Tavera works
Tavera is a selective inhibitor of phosphodiesterase 4 (PDE4), which is an enzyme responsible for the degradation of cyclic adenosine monophosphate (cAMP). Inhibition of PDE4 leads to elevated levels of cAMP, leading to smooth muscle relaxation. Recent research showed that low levels of cAMP have been associated with brain tumorigenesis, leading to the investigation of PDE4 inhibitors as potential anticancer agents.
