Kaverin

Could you clarify what "kaverin" refers to? It could denote different things such as a surname, a brand name for a medication, a place, or something else. If you specify the intended sense (for example: a medication, a person, or a geographic location), I can draft a concise, neutral wiki-style article (under 300 words) accordingly. If you’d like, I can also provide a neutral disambiguation-style entry covering the possible uses.
