Erectile dysfunction (ED), also called impotence, is the type of sexual dysfunction in which the penis fails to become or stay erect during sexual activity. It is the most common sexual problem in men. Through its connection to self-image and to problems in sexual relationships, erectile dysfunction can cause psychological harm.
Sildenafil, sold under the brand name Viagra, among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. It is unclear if it is effective for treating sexual dysfunction in women. It is taken by mouth or by injection into a vein. Onset is typically within twenty minutes and lasts for about two hours.
Tadalafil, sold under the brand name Cialis among others, is a medication used to treat erectile dysfunction (ED), benign prostatic hyperplasia (BPH), and pulmonary arterial hypertension. It is taken by mouth. Onset is typically within half an hour and the duration is up to 36 hours.
Esomeprazole, sold under the brand name Nexium among others, is a medication which reduces stomach acid. It is used to treat gastroesophageal reflux disease, peptic ulcer disease, and Zollinger–Ellison syndrome. Effectiveness is similar to other proton pump inhibitors (PPIs). It is taken by mouth or injection into a vein.
Acarbose (INN) is an anti-diabetic drug used to treat diabetes mellitus type 2 and, in some countries, prediabetes. It is a generic sold in Europe and China as Glucobay, in North America as Precose, and in Canada as Prandase. It is cheap and popular in China, but not in the U.S. One physician explains the use in the U.S. is limited because it is not potent enough to justify the side effects of diarrhea and flatulence. However, a recent large study concludes "acarbose is effective, safe and well tolerated in a large cohort of Asian patients with type 2 diabetes." A possible explanation for the differing opinions is an observation that acarbose is significantly more effective in patients eating a relatively high carbohydrate Eastern diet.
Cyclic guanosine monophosphate-specific phosphodiesterase type 5 is an enzyme from the phosphodiesterase class. It is found in various tissues, most prominently the corpus cavernosum and the retina. It has also been recently discovered to play a vital role in the cardiovascular system.
Ropinirole, sold under the brand name Requip among others, is a medication used to treat Parkinson's disease (PD) and restless legs syndrome (RLS). In PD the dose needs to be adjusted to the effect and treatment should not be suddenly stopped. It is taken by mouth.
The drug udenafil is marketed under the trade name Zydena. It is within the PDE5 inhibitor class (which also includes avanafil, sildenafil, tadalafil, and vardenafil). Like other PDE5 inhibitors, it is used to treat erectile dysfunction. Udenafil was developed by Dong-A Pharmaceutical. It has fairly rapid onset of action (peak plasma concentration after 1 to 1.5 hours), and has long duration of action (plasma half-life of 11 to 13 hours). Udenafil's pharmacokinetics allows once-daily dosage (in addition to on-demand use). Typical doses are 100 and 200 mg. Udenafil is available in Korea, Russia, and the Philippines. It has not yet been approved for use in the United States by the U.S. Food and Drug Administration.
Vortioxetine, sold under the brand names Trintellix and Brintellix among others, is a medication used to treat major depressive disorder. Effectiveness is viewed as similar to that of other antidepressants. It is taken by mouth.
Dapoxetine, marketed as Priligy, among others, is a medication used for the treatment of premature ejaculation (PE) in men 18–64 years old. Dapoxetine works by inhibiting the serotonin transporter, increasing serotonin's action at the postsynaptic cleft, and as a consequence promoting ejaculatory delay. As a member of the selective serotonin reuptake inhibitor (SSRI) family, dapoxetine was initially created as an antidepressant. However, unlike other SSRIs, dapoxetine is absorbed and eliminated rapidly in the body. Its fast-acting property makes it suitable for the treatment of PE, but not as an antidepressant.

Gintonin is a glycolipoprotein fraction isolated from ginseng. The non-saponin ingredient was designated as gintonin, where gin was derived from ginseng, ton from the tonic effects of ginseng, and in from protein. The main component of gintonin is a complex of lysophosphatidic acids (LPA) and ginseng proteins such as ginseng major latex-like protein151 (GLP151) and ginseng ribonuclease-like storage protein.
Gemigliptin (rINN), sold under the brand name Zemiglo, is an oral anti-hyperglycemic agent of the dipeptidyl peptidase-4 inhibitor class of drugs. Glucose lowering effects of DPP-4 inhibitors are mainly mediated by GLP-1 and gastric inhibitory polypeptide (GIP) incretin hormones which are inactivated by DPP-4.
Levamlodipine (INN), also known as levoamlodipine or S-amlodipine is a pharmacologically active enantiomer of amlodipine. Amlodipine belongs to the dihydropyridine group of calcium channel blocker used as an antihypertensive and antianginal agent. Levamlodipine is currently marketed in Russia under the brand name EsCordi Cor, in Brazil under the brand name Novanlo and in India under the trade names Eslo, Asomex, and Espin. In December 2019 Levamlodipine received US FDA approval under the name "Conjupri".
Fimasartan is a non-peptide angiotensin II receptor antagonist (ARB) used for the treatment of hypertension and heart failure. Through oral administration, fimasartan blocks angiotensin II receptor type 1 (AT1 receptors), reducing pro-hypertensive actions of angiotensin II, such as systemic vasoconstriction and water retention by the kidneys. Concurrent administration of fimasartan with diuretic hydrochlorothiazide has shown to be safe in clinical trials. Fimasartan was approved for use in South Korea on September 9, 2010, and is available under the brand name Kanarb through Boryung Pharmaceuticals, who are presently seeking worldwide partnership.
Revaprazan is a drug that reduces gastric acid secretion which is used for the treatment of gastritis. It acts as an acid pump antagonist. Revaprazan is approved for use in South Korea, but is not approved in Europe or the United States.
Hydroxybupropion, or 6-hydroxybupropion, is the major active metabolite of the antidepressant and smoking cessation drug bupropion. It is formed from bupropion by the liver enzyme CYP2B6 during first-pass metabolism. With oral bupropion treatment, hydroxybupropion is present in plasma at area under the curve concentrations that are as many as 16–20 times greater than those of bupropion itself, demonstrating extensive conversion of bupropion into hydroxybupropion in humans. As such, hydroxybupropion is likely to play a very important role in the effects of oral bupropion, which could accurately be thought of as functioning largely as a prodrug to hydroxybupropion. Other metabolites of bupropion besides hydroxybupropion include threohydrobupropion and erythrohydrobupropion.
Lobeglitazone is an antidiabetic drug in the thiazolidinedione class of drugs. As an agonist for both PPARα and PPARγ, it works as an insulin sensitizer by binding to the PPAR receptors in fat cells and making the cells more responsive to insulin.
Dextromethorphan/bupropion (DXM/BUP), sold under the brand name Auvelity, is a combination medication for the treatment of major depressive disorder (MDD). It contains an extended-release combination of dextromethorphan (DXM) and bupropion. The medication is modestly more effective in the treatment of depression than placebo or bupropion alone. It is taken as a tablet by mouth.
HL156A is a derivative of metformin and a potent OXPHOS inhibitor and AMPK activating biguanide. Certain types of cancer cells requires OXPHOS to survive. By targeting it, HL156A might help in improving anticancer therapy. It is more potent than AICAR or metformin at activating AMPK. It is synthesized by Hanall Biopharma.
Sonlicromanol (KH176) is a clinical-stage oral drug compound developed by Khondrion as a potential treatment for inherited mitochondrial diseases, such as Leigh's Disease, MELAS and LHON. Due to dysfunctional mitochondria, an increased level of cellular reactive oxygen species (ROS) is observed in these patients, causing a wide range of symptoms. The active metabolite of Sonlicromanol has several mechanisms of action, acting both as antioxidant and as reactive oxygen species (ROS)-redox modulator. Through selective suppression of microsomal prostaglandin E synthase-1 (mPGES-1), Sonlicromanol even has potency as anti-cancer drug for mPGES-1 overexpressing cancer like prostate cancer. Currently, Sonlicromanol is in phase II clinical trial in the KHENERGYZE, KHENEREXT and KHENERGYC studies as potent candidate in treatment for mitochondrial diseases.
