Ada W Chiu, Robert Stenstrom
Tadalafil is a drug approved for use in erectile dysfunction, but increasingly being used recreationally. There have only been scant case reports on tadalafil causing fixed drug eruption (FDE). Patients who use tadalafil recreationally are less likely to seek medical attention and the diagnosis can often be missed, given the difficulty in diagnosis. However, clinical examination together with a detailed medication history can provide clinicians with good evidence of the association without invasive biopsies...

INTRODUCTION: Phosphodiesterase type 5 inhibitors (PDE5Is) have demonstrated efficacy in the treatment of erectile dysfunction (ED). Although historically found to have limited drug-related adverse events, emerging data have suggested that PDE5Is might be associated with melanoma or recurrence of prostate cancer after radical prostatectomy. AIM: To summarize the literature on the safety of PDE5Is. METHODS: A literature review was performed through PubMed from 1990 through 2016 regarding ED...

To date, there are 80 synthetic PDE-5i found as adulterants in dietary supplements. Analogues of sildenafil remain as the top list with 50 (62%) and are followed by analogues of tadalafil, 21 (26%), analogues of vardenafil, 7 (9%) and others, 2 (3%). The sildenafil group can be sub-categorized into sulphonamide-bonded (24, 48%), acetyl-bonded (11, 22%), carbonyl or thiocarbonyl-bonded (8, 16%) and other types (7, 14%) based on the functional group linked to pyrazolopyrimidine-one moieties. Meanwhile, analogues of tadalafil have become popularly found as adulterants in dietary supplements like beverages and herbal extracts from 2015 to 2016...

We present a review comparing the use of tadalafil daily versus on-demand for erectile dysfunction. We examined randomized controlled trials and observational studies that examined the use of tadalafil for at least 8 weeks of follow-up with the primary outcome of International Index for Erectile Dysfunction- Erectile Function domain (IIEF-EF). Eight studies were identified that examined the desired dosing regimens. Of these, six studies included the primary endpoint of twelve weeks. Those patients taking tadalafil daily for 12 weeks scored on average 1...

Duchenne muscular dystrophy (DMD) is the most common inherited muscular dystrophy. Patients experience DMD in their 20s from cardiac or respiratory failure related to progressive muscle wasting. Currently, the only treatments for the symptoms of DMD are available. Muscle fibrosis, a DMD feature, leads to reduced muscle function and muscle mass, and hampers pharmaceutical therapeutic efficacy. Although antifibrotic agents may be useful, none is currently approved. Phosphodiesterase (PDE)-4 inhibitors have exhibited antifibrotic effects in human and animal models...

The indole scaffold is a prominent and privileged structural motif found in numerous natural products and in a wide range of bioactive heterocycles. Starting from the simple structural framework of serotonin, the well known neurotransmitter to complex alkaloids which are used clinically as anticancer agent, mitomycin C, and the antihypertensive alkaloid reserpine, the indole moiety is considered as the active principle. Thus over the past decade, a large number of indole-containing compounds have revealed remarkable pharmacological activity and their utility as therapeutic agents have attracted considerable attention from chemists...

Tadalafil and sildenafil are selective inhibitors of phosphodiesterase type 5, showing marked pharmacokinetic variability in patients with pulmonary arterial hypertension. It has been reported that sildenafil is a substrate for P-glycoprotein (P-gp), but whether tadalafil is a substrate for P-gp remains to be determined. The objective of the present study was to elucidate whether tadalafil is a substrate for P-gp. Transcellular transport of sildenafil and tadalafil (5 µM each) was examined using renal epithelial LLC-PK1 and P-gp-expressing LLC-GA5-COL150 cell monolayers...

Many drug candidates today have a low aqueous solubility and, hence, may show a low oral bioavailability, presenting a major formulation and drug delivery challenge. One way to increase the bioavailability of these drugs is to use a supersaturating drug delivery strategy. The aim of this study was to develop a video-microscopic method, to evaluate the effect of a precipitation inhibitor on supersaturated solutions of the poorly soluble drug tadalafil, using a novel video-microscopic small scale setup. Based on preliminary studies, a degree of supersaturation of 29 was chosen for the supersaturation studies with tadalafil in FaSSIF...

Purpose: This study was carried out in order to find a reliable method for the fast detection of adulterated herbal food supplements with sexual enhancement claims. As some herbal products are advertised as "all natural", their "efficiency" is often increased by addition of active pharmaceutical ingredients such as PDE-5 inhibitors, which can be a real health threat for the consumer. Methodes: Adulterants, potentially present in 50 herbal food supplements with sexual improvement claims, were detected using 2 spectroscopic methods - Raman and Fourier Transform Infrared - known for reliability, reproductibility, and an easy sample preparation...

High-performance liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS(2)) with a triple quadrupole is proposed for determining the synthetic phosphodiesterase-5 inhibitors, sildenafil, tadalafil and vardenafil, and the active metabolite N-desmethyl sildenafil. The method was successfully applied to the analysis of waters of different origins and human urine samples. Dispersive liquid-liquid microextraction (DLLME) was applied in the classical way for water analysis, whereas a previous extraction into an organic solvent was necessary for urine samples, the acetonitrile extract being used as dispersant solvent in the DLLME step...
