Common Name | Guanethidine |

Description | Guanethidine, also known as octadine or ismelin, belongs to the class of organic compounds known as guanidines. Guanidines are compounds containing a guanidine moiety, with the general structure (R1R2N)(R3R4N)C=N-R5. Guanethidine is a drug which is used for the treatment of moderate and severe hypertension, either alone or as an adjunct, and for the treatment of renal hypertension. Side effects include postural and exercise hypotension, sexual dysfunction (delayed or retrograde ejaculation), and diarrhea.Guanethidine is transported by uptake 1 into the presynaptic terminal transported by norepinephrine transporter (NET). Guanethidine is a very strong basic compound (based on its pKa). Guanethidine is transported across the sympathetic nerve membrane by the same mechanism that transports norepinephrine itself (NET, uptake 1), and uptake is essential for the drug's action. Spontaneous release is not affected.Guanethidine was once a mainstay for hypertension resistant to other agents, and was often used safely during pregnancy, but it is no longer used in the US due to lack of availability. Once inside the terminal it blocks the release of norepinephrine in response to arrival of an action potential. It becomes concentrated in norepinephrine transmitter vesicles, replacing norepinephrine in these vesicles. It is still licensed in some countries, e.g., UK, for the rapid control of blood pressure in a hypertensive emergency. It may also inhibit the release of granules by decreasing norepinephrine. Intravenous nerve block (Bier block) using guanethidine has been used to treat chronic pain caused by complex regional pain syndrome. Once guanethidine has entered the nerve, it is concentrated in transmitter vesicles, where it replaces norepinephrine. This leads to a gradual depletion of norepinephrine stores in the nerve endings. Guanethidine is an antihypertensive drug that reduces the release of catecholamines, such as norepinephrine. |
