Identify
(1) Take the trichloroacetate obtained under the content determination item, and determine the melting point according to the law to be 136 ~ 141 ℃, and decompose at the same time when melting. (2) Take about 30mg of this product, add 15ml of water to dissolve, divide it into three parts, add iodine test solution, mercury potassium iodide test solution and trinitrophenol test solution respectively, all of which will produce precipitation. (3) Take 50mg of this product and 0.2g of sodium hydroxide, add a few drops of water to dissolve, evaporate to dryness over low heat, then slowly heat to melt, continue to heat for a few minutes, let cool, add 0.5ml of water and a little excess of dilute hydrochloric acid, That is, the odor of sulfur dioxide occurs.

 

Assay
Take about 0.2g of this product, accurately weigh it, add 20ml of water to dissolve, slowly add 40ml of 10% trichloroacetic acid solution under stirring, and leave it for 2 hours. , the precipitation was first washed with a small amount of 10% trichloroacetic acid solution, and then washed with 20 ml of cold water below 10 ° C in several batches, and then placed in a phosphorus pentoxide desiccator to dry under reduced pressure to constant weight, and accurately weighed. The weight of the obtained precipitate was the same as Multiply by 0.8487 to get the weight of C17H19N3O.CH4O3S in the test product.

 

Dosage and Administration
1. Intramuscular or intravenous injection for vasospasm, 5 mg/time, 1-2 times/day.
2 Anti-shock intravenous infusion at a dose of 0.3 mg per minute can increase the cardiac output.
3 Diagnosis of pheochromocytoma by intravenous injection of 5 mg, blood pressure measurement every 30 seconds after injection, continuous measurement for 10 minutes, such as blood pressure decreased by 4.67/3.33kPa (35/25mmHg) within 2-4 minutes and maintained for 3- Positive result at 5 minutes.
