Efficacy and Safety of Clostridium Botulinum Toxin Type A to Improve Appearance of Moderate to Severe Glabellar Lines

A solution containing 50 U in 0.25 mL (200 U/mL). Each vial contained 0.625 mL of deliverable volume of solution. A volume of 0.25 mL, containing 50 U of BTX-A-HAC NG (i.e. 10 U/0.05 mL) was withdrawn from the vial into a syringe for administration. The total treatment volume (0.25 mL) was divided into five injections (0.05 mL per injection), each of which was to be administered into predefined sites across the glabellar region (two injections into each corrugator muscle and one injection into the procerus muscle).

A solution containing only the excipients of BTX-A-HAC NG (identical in appearance to the active product). Each vial contained 0.625 mL of deliverable volume of solution. A volume of 0.25 mL was withdrawn from the vial into a syringe for administration. The total treatment volume (0.25 mL) was divided into five injections (0.05 mL per injection), each of which was to be administered into predefined sites across the glabellar region (two injections into each corrugator muscle and one injection into the procerus muscle).
