Abstract
Polyaddition silicone elastomer dosage forms adapted for the continuous and controlled release of iodine values, notably to domestic water supplies for the treatment of the various disease states attributed to iodine deficiency, are shaped from (A) at least one organopolysiloxane containing at least two vinyl groups bonded to silicon per molecule; (B) at least one organopolysiloxane containing at least three hydrogen atoms bonded to silicon; (C) a catalytically effective amount of a platinum group metal compound; and (D) a therapeutically effective amount of at least one water soluble, nontoxic, organic and/or inorganic iodine compound which is in solid or liquid state at ambient temperature and which does not inhibit the catalytic activity of the platinum group metal compound (C).
