Action of Strontium Lactate

The strontium salts were demonstrated by Laborde to be harmless to animals and men. He also ascribed to them a diuretic action. If given for some time and in large quantities they impair gastric digestion and subsequently the general nutrition. The lactate reduces the amount of albumin in albuminuria, and it is claimed to have a sedative effect on the heart in diseases of the valves and of the muscular tissue. It also checks fermentation and putrefaction in the small intestines.

Therapeutics of Strontium Lactate

The strontium salts in gastric affections improve the appetite and facilitate digestion, and are useful in chronic intestinal catarrh. The lactate is diuretic and is useful in albuminuria, due to renal atony, but not in uraemia, nor in interstitial nephritis, nor in the high fever of acute parenchymatous nephritis. In the chronic form due to scrofula, rheumatism or gout it is useful. It has had a decidedly beneficial action in diabetes of hepatic origin, and in cirrhosis of the liver.
