4 . The method of claim 1 wherein at least one of the lysophosphatidic acid antagonists interferes with the activity of lysophosphatidic acid at one or more lysophosphatidic acid receptors selected from the group consisting of LPA 1 , LPA 2 , LPA 3 , LPA 4 , and LPA 5 .
5 . The method of claim 1 wherein one of the TMEM16a inhibitors is tannic acid or a pharmaceutically acceptable salt thereof, or a prodrug of any of the foregoing.
6 . The method of claim 1 wherein the cystic disease is associated at least in part with one or more of polycystic kidney disease, Bardt Biedl syndrome, nephronophthisis, Meckel Gruber syndrome, or oral-facial-digital syndrome.
7 . The method of claim 1 wherein the cyst resides in an internal organ.
8 . The method of claim 7 wherein the internal organ is selected from the group consisting of kidney, liver, and pancreas.
9 . The method of claim 1 wherein the lysophosphatidic acid antagonist is administered orally, parenterally, or by injection.
10 . The method of claim 9 wherein the lysophosphatidic acid antagonist is administered by injection.
11 . The method of claim 10 wherein the injection is intravenous.
12 . The method of claim 10 wherein the injection is intrahepatic.
13 . The method of claim 10 wherein the injection is intrarenal.
14 . The method of claim 10 wherein the injection is intrapancreatic.
15 . The method of claim 10 wherein the injection is a direct infusion.
16 . The method of claim 1 wherein the lysophosphatidic acid antagonist is administered via an implanted device.
