Duchesnay announces the launch of Vablys® (dequalinium chloride vaginal tablets), an antiseptic and anti-infective treatment for bacterial vaginosis

BLAINVILLE, QUEBEC – June 21, 2022 – Duchesnay Inc, a pharmaceutical company specializing in women’s health and part of Duchesnay Pharmaceutical Group headquartered in Blainville, Quebec, is pleased to announce that it has launched its newest treatment, Vablys® (dequalinium chloride vaginal tablets).

Vablys® is the first prescription antiseptic and anti-infective treatment for bacterial vaginosis in women under 55 years of age. With its multiple modes of action and anti-infective properties against a wide range of pathogens, a treatment course of Vablys consists of one tablet inserted in the vagina at bedtime for six consecutive days.

“Vablys® offers Canadian physicians and their patients the first gynecological anti infective and antiseptic prescription treatment option, said Gino Henry, Senior Manager, Commercial Affairs, at Duchesnay. “We’re convinced that our product provides a new and effective way to treat this condition.” 1

Vablys® is the third new prescription treatment for Canadian women launched by Duchesnay in 2022, achieving an aggressive target set by the company’s new management team. The other two new treatments are the contraceptive Slynd® (drospirenone), a progestin-only pill (POP) which offers a 24-hour safe window for a missed pill, during which no other contraception is needed to prevent pregnancy, and Osphena® (ospemifene tablets), a selective estrogen receptor modulator (SERM) approved by Health Canada as a once-daily prescription treatment for postmenopausal women to treat vaginal dryness and painful intercourse.

“Duchesnay is very proud to have achieved its ambitious target of bringing three new innovative prescription treatments to Canadian women in the first six months of 2022, a key element of our growth plans under our new management team,” said Dany Hallé, Vice-President, Commercial Affairs at Duchesnay.

“All three new treatments address important needs for women at different stages of their lives and demonstrate concretely the commitment of Duchesnay to providing women’s health solutions. We look forward to continuing to do so.”

About bacterial vaginosis

Bacterial vaginosis (BV) is an imbalance of the naturally-occurring, healthy bacteria found in the vagina or internal genitals. This imbalance can cause symptoms that may include more vaginal discharge than usual, a fish-like smell or irritation in the vaginal area2, though often symptoms are not noticed. According to the Public Health Agency of Canada, bacterial vaginosis is the most common cause of vaginal discharge in people of reproductive age. Bacterial vaginosis is not usually considered sexually transmitted, but it is associated with increased acquisition of human immunodeficiency virus (HIV), human papilloma virus (HPV) and Chlamydia trachomatis (CT).3
