Hi Manush, this is quite a combination of roles you have here. Most of the duties are that of an industrial pharmacist, other than the dispensing directly to patients bit. (I have never heard of an industrial research pharmacist dispensing drugs so please let me know if you have a unique position.)
I'm going to have to assume that you gathered this experience in 2 different jobs probably with 2 different employers. Anyway, I suggest you apply as 'Pharmacist' since this would include all kinds; retail, industrial, hospital etc. However, in your reference letters mention your exact duties as per the role in a certain period of time. For example, if you were an industrial pharmacist for a year, prepare a reference letter for that time period mentioning your duties in that position. Similarly, make a separate letter for retail pharmacist duties. All the best.
