Drugs for functional gastrointestinal disorders

Drotaverine-Darnitsa is an isoquinoline derivative that exerts antispasmodic action on smooth muscle via inhibition of phosphodiesterase–4 (PDE4), resulting in an increase in the cAMP concentration and leading to smooth muscle relaxation due to inactivation of the myosin light chain kinase (MLCK). In vitro, drotaverine suppresses the action of PDE4 and inhibits isoenzymes phosphodiesterase-3 (PDE3) and phosphodiesterase-5 (PDE5).

For the treatment of:

– Smooth muscle spasms in the biliary tract diseases: cholecystolithiasis, cholangiolithiasis, cholecystitis, pericholecystitis, cholangitis, papillitis
– Smooth muscle spasms in the urinary tract diseases: nephrolithiasis, urethrolithiasis, pyelitis, cystitis, vesical tenesmus

As an adjuvant treatment in:

– Smooth muscle spasms in the gastrointestinal tract diseases: gastric and duodenal ulcers, gastritis, cardio- and/or pylorospasm, enteritis, colitis, spastic colitis with constipation and irritable bowel syndrome with flatulence
– Stress headache
– Gynecological diseases (dysmenorrhea)
