Can cetrizine and piriton cure the same disease? or can be used for same purpose?

Piriton (chlorphenamine) is a 1st generation sedating antihistamine. Cetirizine is a second-generation antihistamine. They both treat allergy symptoms. 1st generation antihistamines can interfere with learning and memory, impair performance, decrease work productivity, and increase the risk of motor vehicle accidents and on-the-job injuries. https://www.cmaj.ca/content/193/14/E478
