Pharmacokinetics of a prototype formulation of sublingual testosterone and a buspirone tablet, versus an advanced combination tablet of testosterone and buspirone in healthy premenopausal women.

The study aimed to compare the kinetics of two novel combination drug products for Female Sexual Interest/Arousal Disorder (FSIAD). Thirteen women received testosterone via the sublingual route followed 2.5 hours later by a buspirone tablet, versus a single combination tablet swallowed at once.

Two novel combined drug treatments for women with hypoactive sexual desire disorder.

Low sexual desire is the most common sexual complaint in women. As a result, many women suffer from sexual dissatisfaction which often negatively interferes with their quality of life. These complaints have been classified as the condition Hypoactive Sexual Desire Disorder (HSDD), and have recently been merged with the condition Female Sexual Arousal Disorder (FSAD) into the diagnosis Female Sexual Interest/Arousal Disorder (FSIAD) in the DSM-5.

Toward personalized sexual medicine (part 1): integrating the "dual control model" into differential drug treatments for hypoactive sexual desire disorder and female sexual arousal disorder.

In three related manuscripts we describe our drug development program for the treatment of Hypoactive Sexual Desire Disorder (HSDD). In this first theoretical article we will defend the hypothesis that different causal mechanisms are responsible for the emergence of HSDD: low sexual desire in women (with HSDD) could be due to either a relative insensitive brain system for sexual cues or to enhanced activity of sexual inhibitory mechanisms. This distinction in etiological background was taken into account when designing and developing new pharmacotherapies for this disorder.

Toward personalized sexual medicine (part 2): testosterone combined with a PDE5 inhibitor increases sexual satisfaction in women with HSDD and FSAD, and a low sensitive system for sexual cues.

Introduction: Low sexual desire in women may result from a relative insensitivity of the brain for sexual cues. Administration of sublingual 0.5 mg testosterone (T) increases the sensitivity of the brain to sexual cues.

Toward personalized sexual medicine (part 3): testosterone combined with a Serotonin1A receptor agonist increases sexual satisfaction in women with HSDD and FSAD, and dysfunctional activation of sexual inhibitory mechanisms.

Introduction: Among other causes, low sexual desire in women may result from dysfunctional activation of sexual inhibition mechanisms during exposure to sex. Administration of sublingual 0.5 mg testosterone (T) increases the sensitivity of the brain to sexual cues, which might amplify sexual inhibitory mechanisms further in women already prone to sexual inhibition.
