A glucosid, or mixture of glucosids. obtained from strophanthus.

Properties : Strophanthin occurs as a white or faintly yellowish powder, having an intensely bitter taste. Because of its toxicity great caution should be used in tasting it. It is very soluble in water and in diluted alcohol, but less soluble in absolute alcohol.

Action and Uses: Strophanthin is used like digitalis. It acts more rapidly and is excreted sooner and hence is regarded as preferable for administration in acute conditions and in emergencies. It is not readily absorbed from the gastrointestinal tract; hence its oral use is not recommended.

Dosage: 0.0003 gm. or 1/200 grain. It is best administered intramuscularly or intravenously, only a single dose being given daily, as a rule.
