New and Emerging Therapeutic Drugs for the Treatment of Pulmonary Arterial Hypertension: A Systematic Review. (PubMed, Cureus) - "Several FDA-approved therapeutic options are available, including prostacyclin analogs (epoprostenol, iloprost, and treprostinil), the non-prostanoid IP receptor agonist selexipag, selective endothelin receptor antagonists (ERA) (ambrisentan, bosentan, and macitentan), phosphodiesterase 5 inhibitors (sildenafil and tadalafil), and the soluble guanylate cyclase (sGC) stimulator riociguat...The review found that while udenafil, imatinib, racecadotril, sotatercept, anastrozole, riociguat, tacrolimus, and ralinepag were evaluated, imatinib was notably associated with adverse side effects. Conversely, udenafil, racecadotril, sotatercept, anastrozole, riociguat, tacrolimus, and ralinepag were found to be safe, well-tolerated, and effective in improving hemodynamic measures and 6-MWDs. This study aims to summarize the developing treatment options currently under clinical trials, highlighting the need for further trials before their application in clinical practice."

An overview of conventional and investigational phosphodiesterase 5 inhibitors for treating erectile dysfunction and other conditions. (PubMed, Expert Opin Investig Drugs) - "Pre-clinical and early clinical trials that investigated safety, efficacy and tolerability of novel PDE5I such as Udenafil, Mirodenafil, Lodenafil, Youkenafil, Celecoxib and TPN729 in treatment of ED and other conditions. Preclinical and limited early clinical studies of the new molecules of PDE5I have demonstrated encouraging results however, safety, efficacy, and tolerability are still an issue that necessitate further long-term multicenter clinical studies to ensure justification of their uses in treatment of ED and other conditions.Progress in molecular delivery techniques and tailored patient-specific management and additional therapeutic technology will dramatically improve care for ED and other conditions. The dream of ED and many other conditions becoming more effectively managed may be feasible in the near future."

Nicolau syndrome (embolia cutis medicamentosa) due to glatiramer acetate (Copaxone) injection: a case report (BAD 2024) - "Drug history included glatiramer acetate, levothyroxine, pregabalin, udenafil, propranolol, levetiracetam and docusate...Oral doxycycline 100 mg once daily was started, as a swab showed a heavy growth of Staphylococcus aureus...Conservative treatment with debridement, pain control and dressings are the mainstays of therapy. This case highlights the need for awareness about this rare condition."

Postmicturition dribble in men with no previous urogenital surgery: Systematic review and meta-analysis of treatment modalities. (PubMed, Neurourol Urodyn) - "Physical/behavioral therapy and PDE5 inhibitors are effective primary PMD treatments. PMD management studies in males with no previous urethral/prostatic surgery are very scarce and lack the use of consistent/comparable outcome measures. Further studies addressing these deficiencies would benefit this very thin evidence base."

The Effect of Udenafil on Heart Rate and Blood Pressure in Adolescents With the Fontan Circulation. (PubMed, Am J Cardiol) - "There were no clinically significant differences between treatment and placebo group in change in HR or blood pressure in the youngest age quartile, lightest weight quartile, or those on afterload-reducing agents. In conclusion, initiation of treatment with udenafil in patients with Fontan circulation was not associated with clinically significant changes in vital signs, implying that for patients similar to those enrolled in the FUEL trial, udenafil can be started without the requirement for additional monitoring after initial administration."

Phosphodiesterase 5 inhibitors: preclinical and early phase breakthroughs for impotence treatments. (PubMed, Expert Opin Investig Drugs) - "Our review of udenafil, mirodenafil, youkenafil, lodenafil, and SLx-2101 analyzes the safety, efficacy, and pharmacokinetic properties of these new ED drugs. It is our opinion that more robust clinical trials are required before these medications can be made available in the United States. Additionally, the field of urology may benefit from pursuing other avenues of pharmacotherapy, such as injections, tablets with a different mechanism of action, or stem cell therapy, to restore the integrity of the endothelium within the penis."

The Fontan Udenafil Exercise Longitudinal Trial: Subgroup Analysis.

Further work is warranted to confirm the potential benefit of udenafil and to evaluate the long-term tolerability and safety of treatment and to determine the impact of udenafil on the development of other morbidities related to the Fontan circulation.Trial Registration NCT0274115."

Using a quantum dot bead-based lateral flow immunoassay to broadly detect the adulteration of PDE-5 inhibitors in functional foods. (PubMed, Anal Methods) - "For the determination of lodenafil, methisosildenafil, mirodenafil, udenafil and tadalafil, the limit of detection (LOD) and IC ranged from 1.01 to 26.91 ng mL and 12.75 to 278 ng mL, respectively. In addition, the validity and the consistency have been confirmed with a comparison between QB-LFIA and HPLC-MS/MS (R = 0.9957). Furthermore, the developed QB-LFIA was employed for the inspection of real products, and several samples were found to be adulterated with lodenafil and methisosildenafil."

Rubus occidentalis and Ellagic Acid Affect the Contractility of Penile Corpus Cavernosum Smooth Muscle through the Nitric Oxide-Cyclic Guanosine Monophosphate and Cyclic Adenosine 3',5'-Monophosphate Signaling Pathway. (PubMed, J Clin Med) - "The interaction of ROE or EA with phosphodiesterase (PDE) 5 and PDE4 inhibitors, such as udenafil (UDE) and rolipram (ROL), were also evaluated...Furthermore, the treatment of ROE and EA markedly increased the UDE- and ROL-induced relaxation of the PCCSM. In conclusion, ROE and EA induced PCCSM relaxation by activating the nitric oxide (NO)-cGMp and cAMp signaling pathways and may have a synergistic action to improve erectile function."
