Oxytocin for male orgasmic disorder: fact or fiction? (AUA 2025) - "This starts with vibratory stimulation, followed by oxytocin, bupropion, and cabergoline, and finally bremelanotide and flibanserin. Intranasal oxytocin failed to significantly improve orgasmic disorder in the majority of men in our cohort. Male orgasmic disorder remains a difficult to treat condition. A significant proportion of patients with orgasmic disorder are co-morbid with erectile dysfunction and a psychiatric diagnosis, most commonly major depressive disorder."

Efficacy of Bremelanotide (BMT) to Stabilize Podocyte Function and Reduce Proteinuria in Adults with Type II Diabetic Nephropathy: Results from a Phase IIb, Open-Label Study. (NKF-SCM 2025) - "Post-hoc analysis demonstrated that BMT therapy increased urinary VEGF levels in 37.5% of patients and reduced urinary synaptopodin levels by ≥30% in 50% of evaluable patients, consistent with previous reports that activation of melanocortin receptors can block synaptopodin degradation and stabilize podocyte function and viability. Further studies will need to be conducted using various combinations of MCR receptor agonists and antagonists to fully optimize this promising treatment pathway."

Female Syrian hamster analyses of bremelanotide, a US FDA approved drug for the treatment of female hypoactive sexual desire disorder. (PubMed, Neuropharmacology) - "Finally, sexual experience resulted in a conditioned place preference (CPP) in female Syrian hamsters, though bremelanotide treatment failed to enhance sexual reward in this test. The results of this study are discussed in conjunction with similar studies in rats, with the conclusion that bremelanotide does not act on the VTA-NAc reward circuit and does not enhance the rewarding effects of sexual interactions."

Pharmacotherapy of Hypoactive Sexual Desire Disorder in Premenopausal Women. (PubMed, Ann Pharmacother) - "Through a literature search on PubMed, Google Scholar, and ClinicalTrials.gov from 1999 to 2024, studies were selected using the following MeSH search terms: hypoactive sexual desire disorder, premenopause, pharmacologic management, flibanserin, bremelanotide, buspirone, bupropion, and testosterone, excluding those involving postmenopausal women or other sexual disorders. Further research with the most suitable clinical endpoints and consideration of patient factors are crucial before widespread adoption of flibanserin and bremelanotide. Pharmacists are encouraged to embrace this opportunity to provide premenopausal HSDD care in ambulatory and community practice settings."
