Mdma hyponatremia

Online: Now


We investigated potential mechanisms in two double-blind, placebo-controlled studies. In Study 1, healthy drug-experienced volunteers received MDMA or placebo alone and in combination with the alpha-1 adrenergic inverse agonist prazosin, used as a positive control to release antidiuretic hormone ADH. Water loading reduced serum sodium more after MDMA than after placebo. There was a trend for women to have lower baseline serum sodium than men, but there were no ificant interactions with drug condition. Combining studies, MDMA potentiated the ability of water to lower serum sodium. Thus, hyponatremia appears to be a ificant risk when hypotonic fluids are consumed during MDMA use.

Males weighed Presenting symptoms are headache, nausea and vomiting followed by altered mental status, coma, seizure, cardio respiratory arrest, brainstem herniation and death [ 5 ]. To minimize effects of water consumption, participants were limited to drinking 1 pt about mL or less of water each hour.


The sudden historic appearance of MDMA-related hyponatremia strongly suggests a behavioral component [ hyyponatremia ]. Hypertonic saline should be given intravenously in more severe cases, or for serious complications, such as treating seizures due to hyponatremia.

There was a trend for women to have lower baseline serum sodium than men, but there were no ificant interactions with drug condition. ADH, also known as vasopressin, is a hormone that inhibits urination by promoting increased water reabsorption by the kidneys.

We collected urine in pooled samples before dosing and 0—8 and 8—24 h after. Toxicology screening in these patients expedites active management and allows preventive management in anticipation of new symptoms and complications. Hyponatremic encephalopathy in the outpatient setting is usually seen as a complication due to medications such as thiazide diuretics or SSRIs, hypoantremia can result from exercise-associated hyponatremia or psychogenic polydypsia [ 3 ]. An experimental study in healthy volunteers has shown that administration of 40 mg of MDMA a very low dose produced a marked rise in levels of ADH in plasma, which was accompanied by a small fall in the sodium concentration Henry et al.

Patients at highest risk of developing hyponatremic encephalopathy in the hospital setting are post-operative patients and patients with SIADH receiving hypotonic fluids [ 2 ].

Advances in pharmacological and pharmaceutical sciences

In contrast, most other syndromes of MDMA-related toxicity predominantly involve males. This is a particularly dangerous complication as hypoxia impairs brain cell volume regulation, decreases cerebral perfusion and increases the probability of developing neuronal lesions [ 215 ].

Her clinical presentation was felt to be consistent with acute severe hyponatremia caused by a variant of syndrome of inappropriate antidiuretic hormone SIADH and was likely drug induced. The hyplnatremia sodium also may cause nausea, cramps, weakness, fatigue, confusion, and seizures that may be very difficult to control. She was agitated, confused, and incoherent on arrival and unable to provide a medical history.

This article has been cited by other articles in PMC. ADH is highly bound to platelet, which hyponztremia produce artefactually high or low measurements depending on handling of samples [ 27 — 29 ].

Mdma impairs response to water intake in healthy volunteers

A study of ecstasy users by Aitchison et al. We used opaque gelatin capsules to hold MDMA and overencapsulate prazosin.

She made a swift and uneventful recovery. Symptomatic hyponatremia from passive flow of water into cells, which can cause cerebral edema and may result in brain stem herniation. Ecstasy is hyponattremia taken on such occasions for its mood-enhancement properties. We selected 1.

Hyponatremic encephalopathy induced by “ecstasy”

Purdue University, IN. Ecstasy-induced hyponatremia can be compared to the syndrome of inappropriate secretion of antidiuretic hormone SIADH. Rave mdna are extremely popular in North America and Europe, with thousands of people in attendance at rave events.

Dumont et al. Hyponatremia after MDMA also likely has behavioral risk factors.

Conflict of interest statement

There are over 25 reports of ecstasy-associated hyponatremic encephalopathy in the literature, and over half of them are fatalities. The high prevalence of females in MDMA-related hyponatremia is also seen in hyponatremia from other causes e. There is strong gender imbalance in MDMA-related hyponatremia. One case of MDMA-induced hyponatremia has been documented in which the ADH level was measured, and it was confirmed that this level was inappropriately raised.

One of the most serious medical complications associated with ecstasy use is hyponatremic encephalopathy [ 11 ]. She was sedated and intubated for airway protection because she demonstrated a ificant risk of aspiration. For sodium, the interassay coefficients of variation were 0. It is a major cause of death in hyponatremia.

In severe cases, hyponatremia may lead to seizures, coma, and death. The hyponatremua low sodium level may be relatively close to normal, because the change has occurred suddenly and the cells have had less time to adapt to the low plasma osmolality a measure of dilution. The first two participants 1 male, 1 female received two mg prazosin. Rella cautions that this treatment may actually exacerbate the fluid and electrolyte problems the patient may be experiencing.
