Pfizer is reducing the price of its blockbuster drug for erectile dysfunction, bringing the cost of Viagra in line with generic versions.

The move follows a ruling from the Supreme Court of Canada that invalidated the Viagra patent held by the pharmaceutical giant.

This month’s ruling threw open Canada’s market for generic drugs.

Pfizer Canada says the decision to lower the cost reflects the company’s commitment to ensuring patients have access to the original Viagra at a competitive price.
