A man was stabbed in the neck during a fight outside a drugstore near Times Square, authorities said.

The 36-year-old victim got into an argument with the attacker and another man while inside the Duane Reade on Eighth Avenue and West 42nd Street around 2:40 a.m. Wednesday.

When the victim stepped outside, one of the men approached him and stabbed him in the neck, cops said.

The suspect then fled north on Eighth Avenue and was still on the loose.

The victim, who has a long criminal history, was taken to Bellevue Hospital with serious injuries.
