Thus sildenafil and potentially other PDE5 inhibitors may have therapeutic benefit in a variety of pathologies, preventable or treatable by gasotransmitters including NO, H2S or CO. As recently reviewed by Kloner and colleagues (Kloner et al., 2011), in addition to the well-defined vascular protective effects of PDE5 inhibitors in non-diabetic conditions (Aversa et al., 2007; Mazo et al., 2006; Rosano et al., 2005), several pre-clinical and clinical studies have also focused on the effects of PDE5 inhibitors on arterial endothelium, which is adversely affected by hyperglycemia in type 2 diabetes (T2D). Eurycoma Longifolia, or tongkat ali, is a plant native to Indonesia and Malaysia. Other alternative therapies thought to help ED include Panax ginseng, Rhodiola Rosea, the herb ashwagandha, and ginkgo Biloba, but more studies are needed to know their safety and efficacy. One of the major causes of chemotherapy failure in cancer treatment is multidrug resistance (MDR) as a result of overexpression of the ATP-binding cassette (ABC) transporters, such as P-glycoprotein (ABCB1/P-gp/MDR1), multidrug-resistance proteins (ABCCs/MRPs) and breast cancer resistant protein (ABCG2/BCRP). Analysis of the impact of androgen deprivation therapy on sildenafil citrate response following radiation therapy for prostate cancer. Interestingly, sulindac, selectively enhanced killing of cancer cells exposed to oxidizing agents via production of ROS (Resnick et al., 2009). PDE5 inhibitors also enhance the chemotherapeutic efficacy of anticancer drugs in prostate and other cancers. This study showed that such an anti-remodeling mechanism was independent of vascular, endothelial, or metabolic factor.

HHS Vulnerability Disclosure, Help These findings illustrated that the cardioprotective effects of sildenafil in vivo cannot be solely attributable to its vasoactive properties. Interestingly, endothelial functional improvement following daily treatment with 50 mg sildenafil for 30 days in 40 patients with T2D was also associated with a significantly reduced albuminuria and glycated hemoglobin (HbA1c)(Grover-Paez et al., 2007), possibly through sildenafil-induced improvement in pancreatic endothelial dysfunction. (2015). Larger 20-mg tablets cost upwards of $70. Additionally, adenosine A1 receptor (A1AR) mediated the cytoprotective effects of sildenafil since it failed to reduce cell death in adult cardiomyocytes isolated from A1AR knockout mice or wild type cardiomyocytes treated with the A1AR antagonist, 8-cyclopentyl-1,3-dipropyxanthine (Salloum et al., 2007a). Inhibiting PDE5 can relax muscles and increase blood flow to specific areas of the body, which is why PDE5 inhibitors such as tadalafil (Cialis), sildenafil (Viagra), and vardenafil (Levitra) are primarily used to treat erectile dysfunction in men.
