Desmopressin improves the brain’s ‘filing mechanism’, allowing memories to be recalled quickly and easily Desmopressin is the synthetic version of vasopressin, a peptide hormone found naturally in the brain and partly responsible for ‘inserting’ memories in the hippocampus, the region of the brain where memories are stored.
Desmopressin rapidly improves short-term memory and enhances memory imprinting. Desmopressin is sometimes used for the treatment of diabetes insipidus, a condition of frequent urination and extreme thirst. In some countries, Desmopressin is used for amnesia and to treat narcotic-related mental problems.
Whereas many common memory drugs improve the capability to remember past events easier and faster, Desmopressin helps us to remember future events better! That is, taking Desmopressin before an event, firmly imprints the event in the mind, enabling it to be recalled with more detail later. Consequently, Desmopressin is of particular benefit before lectures, business meetings and other such occasions. Dosage:
Insert one or two sprays into each nostril (each spray contains 10mcg) 15 minutes before recall or concentration is required. The effect can take place within seconds and last for up to several hours.
Nausea and headaches
Desmopressin should be used infrequently. It should be avoided completely if you suffer from cardiovascular problems. Avoid the intake of large amounts of liquids as Desmopressin tends to decrease the frequency of urination.
Vasopressin (also known as Diapid®) is of bovine and porcine origin, and has now been withdrawn from the world market. Desmopressin is more potent than Vasopressin and should be used in lower doses. Also, Desmopressin affects other brain receptor sites to a greater degree than the Vasopressin version.
Desmopressin should be kept in a fridge although it is stable for several weeks at room temperature.
VASOPRESSIN (MINURIN) / DESMOPRESSIN
Biogenesis Note: We would advise using vasopressin on a need to only basis, i.e. when maximum concentration, retention and alertness is required. Dosages are described here are for mild diabetes, although we have also seen similar for the treatment of amnesia. Refrigeration is NOT required. Note that this more potent synthetic form of Vasopressin (Desmopressin) now replaces the earlier animal sourced Vasopressins (Lypressin and Pitressin).
