Just to confirm,

The white oval pill in question marked "RP 144" is reportedly identified as an over-the-counter Lactase enzyme for treating lactose intolerance.

For verification, the manufacturer is Raritan Pharmaceuticals (hence the "RP").

Unfortunately, Raritan Pharmaceuticals does not list products on their webpage. However, you can contact them directly for specific product information at:

Raritan Pharmaceuticals Inc.
