Dr Reddy's Laboratories, the second largest Indian pharma giant, has commenced marketing of Bispec (Solifencin succinate) in India for the treatment of over active bladder (OAB). Bispec is the best-in-class for OAB and has lesser incidence of dry mount and constipation. The product is available in tablet form and in dosages of 5 mg and 10 mg.

People suffering from OAB have a warning time of about 12 seconds. Solifencin succinate helps to increase the warning time to about 32 seconds.

The market size for product used in the treatment of OAB is about Rs 19.4 crore and it growing at a rate of 7 per cent per annum. Solifencin acts by competitively inhibiting Acetyl choline from binding to cholinergic receptors present in bladder. This reduces bladder contractions and improves warning time in over active bladder patients. DRL has other leading brand TORQ in this segment.
