This matter was investigated by the Editor-in-Chief of the journal and based on the investigation this correction is being published. The Journal of Obstetrics and Gynecology of India does not support publication of pharmaceutical company sponsored articles. The co-author of this article has declared a conflict of interest as an employee of the manufacturing company of the drug helped in this review, and hence, readers are advised to take into account a possible bias.
