Sample Use Guides

In Vivo Use Guide

Thenalidine was given in coated tablets, each containing 25 mg. of the active ingredient. The initial dosage was 2 tablets 4 times a day until the patient improved, or for at least one week. The maintenance dose varied between 3 and 6 tablets daily, 4 tablets daily being the average. Intravenous injection of 10 ml. of thenalidine tartrate plus calcium (50 mg. of Sandostene and 1.375 g. of calcium gluconogalactogluconate) was given in a few severe and acute cases only.
