Summary
Flibanserin targets serotonin receptors in the brain to modulate dopamine and noradrenaline levels. This mechanism is key to enhancing sexual desire in women.
Area of Science:
- Neuropharmacology
- Neuroscience
- Endocrinology
Background:
- Serotonin plays a complex role in regulating mood and sexual function.
- Dysregulation of monoamine neurotransmitters is implicated in hypoactive sexual desire disorder (HSDD).
Purpose of the Study:
- To elucidate the neuropharmacological mechanism of flibanserin in treating HSDD.
- To understand how flibanserin influences neurotransmitter systems critical for sexual desire.
Main Methods:
- Flibanserin's action on serotonin 5-HT1A autoreceptors and 5-HT2A receptors was investigated.
- The drug's impact on the turnover of dopamine and noradrenaline was assessed.
Main Results:
- Flibanserin inhibits serotonin release by binding to 5-HT1A autoreceptors.
- It also blocks postsynaptic serotonin action at 5-HT2A receptors.
- This leads to the disinhibition of dopamine and noradrenaline turnover.
Conclusions:
- Flibanserin's mechanism involves modulating serotonin to indirectly increase dopamine and noradrenaline.
- This neurochemical modulation is crucial for its therapeutic effect on sexual desire.

Treatment approaches for psychological disorders fall into three main categories: psychological, biological, and sociocultural. Each approach targets different aspects of mental health, requiring varying levels of education and training.
Psychological therapies focus on modifying emotions, thoughts, and behaviors through talking, interpreting, listening, rewarding, challenging, and modeling. Clinical psychologists, counselors, and social workers commonly practice psychotherapy. Clinical...

01:28Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors
728
Phosphodiesterase 5 (PDE5) inhibitors are potent enzymes that function to hydrolyze cyclic nucleotides to their corresponding 5' monophosphates. Their unique biochemical properties have been applied in treating Pulmonary Arterial Hypertension (PAH).
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

01:23Psychosexual Stages of Personality: Genital
2.1K
The genital stage is the final phase of Sigmund Freud's theory of psychosexual development, beginning at puberty, around age 12. During this stage, sexual energy shifts from self-focused interests to external individuals, marking the development of mature adult sexuality. Freud saw this phase as a time of sexual reawakening, with desires directed toward others outside the family. A healthy transition into this stage, according to Freud, signifies the emergence of two key aspects of adult...

01:17Male Sexual Response: Erection & Ejaculation
27.0K
Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

01:23Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
602
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
