If you have pharmacy degree from nepal, you can still continue doing PHD over here.you don't need to repeat pharmacy again..it is useless and very expensive... I have some of my friends just like you who have pharmacy degree from india and they are doing PHD over here, .....so this will make better chances with two degree to get work in industry....sorry i have no idea about B pharm + MBA...you might get also ..who knows..good luck...
