Simple explanation.
Pharmacy technicians are gaining more ground than pharmacists are towards provider status with the ability to now vaccinate and provide final verification of prescriptions. Therefore, it is no longer necessary for pharmacy students to take immunization class, OTC class and “Top 200 drugs” class. That’s an easy 2 months worth of curriculum that can be shaved off right there (applied to a 3 year accelerated program gives you 2 years 10 months).
In the future I can even see curriculums go down to 2 years in length as schools get rid of more general ed classes (basically most of the other coursework you’d take during P1 year). If anything, I can make an argument that pharmacy school can be done with 1 year of didactic curriculum (therapeutics only) and 1 year of rotations.
