„Aesculapius” is not only an active association in Leiden, but also has contacts with the associations in Groningen and Utrecht. G.F.S.V. “Pharmaciae Sacrum” (P.S. in short) from Groningen was founded in 1991, which makes it not only the oldest study association in Groningen, but also the oldest of the three Dutch pharmaceutical students’ associations. U.P.S.V. “Unitas Pharmaceuticorum” (U.P. in short) was founded in 1894. but is, just like „Aesculapius”, the oldest study association in its city. The three study associations, P.S., „Aesculapius”, and U.P., are united by the K.N.P.S.V., the Royal Dutch Pharmaceutical Students’ Association.
Furthermore, „Aesculapius” maintains contact with the chemical sister associations that are affiliated with the KNCV (the Royal Dutch Chemical Association). Also, „Aesculapius” maintains contact with the other science associations at the faculty of Science of the Leiden University. The board communicates with them about joint activities such as the faculty party, the science gala and the open mic night.
Finally, the Association also maintains contact with all other study associations of the Leiden University.
