Guanetidine (5–40 mg/kg; i.p.; daily; 4-28 days; male Wistar rats) Treatment at 40 mg/kg for 28 days causes partial sympathectomy and related reaction to norepinephrine; however, 5 mg/kg does not result in permanent hemodynamic alterations or histological changes [3].

| Animal Protocol |
Animal/Disease Models: Male Wistar rat (approximately 200 grams) [3]
Doses: 5 mg/kg or 40 mg/kg Route of Administration: intraperitoneal (ip) injection; daily; continued for 4, 8, 14 or 28 days Experimental Results: blood pressure diminished by 40 mg/kg, the decrease in blood pressure can be reversed after stopping the drug. The hypersensitivity reaction was partially reversible after discontinuation of the drug, but a significant increase in heart rate sensitivity to norepinephrine was observed 60 days after discontinuation of the drug, and 40 mg/kg was administered for 28 days. Histologically, severe loss of superior cervical ganglion nerve cells was observed at the 40 mg/kg dose. |

| Additional Infomation |
An antihypertensive agent that acts by inhibiting selectively transmission in post-ganglionic adrenergic nerves. It is believed to act mainly by preventing the release of norepinephrine at nerve endings and causes depletion of norepinephrine in peripheral sympathetic nerve terminals as well as in tissues.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
