Open labelled evaluation of injection Manyana (a combination of diclofenac + pitofenone + fenpiverinium) in ureteric, biliary and intestinal spasm--a preliminary report.

To study the efficacy and safety of a parenteral formulation of 'Manyana' (a combination of diclofenac + pitofenone + fenpiverinium) in ureteric, biliary and intestinal colic, an open labelled study was conducted at two centres. A total of 206 patients were enrolled and evaluated for decrease in pain with time on a visual analogue scale. A statistically significant difference was observed in pain within 30 minutes of drug administration and the pain relief lasted for as long as 24 hours post dosing. The study shows definite synergism between the antispasmodics pitofenone and fenpiverinium with the NSAID-diclofenac, reducing the prostaglandin levels and also the spasm related to colic.
