MDMA (ecstasy) but not methylphenidate (Ritalin) acutely alters several steroid hormones over 24 hours. In 16 healthy adults given single doses of MDMA (125 mg), methylphenidate (60 mg), both drugs together, or placebo on separate days, MDMA raised cortisol, corticosterone, 11-dehydrocorticosterone, and 11-deoxycorticosterone, and tended to increase aldosterone, while leaving cortisone, DHEA, DHEAS, androstenedione, and testosterone unchanged. Methylphenidate alone did not affect any steroid levels and did not modify MDMA's effects. These results indicate that serotonin release, not dopamine or norepinephrine stimulation, drives acute activation of the hypothalamic-pituitary-adrenal axis by these drugs.
