Next to those that have been already discussed such as Hydroxychloroquin, here is a list from a patent I found as I was looking in depth at the autophagy inhibition property of loratadine:

albendazole,
carbazochrome sulfonic acid,
carvedilol,
cinacalcet,
clemastine,
clomifene,
loratadine,
pimobendan,
testosterone enanthate ester,
zonisamide

Here is the scientific article that is probably at the origin of the list above, and the article actually includes more autophagy inhibitors, including Retinoic Acid https://www.cell.com/molecular-cell/pdfExtended/S1097-2765(16)30589-5
