Silicosis is a crippling respiratory disorder characterized by massive lung inflammation and fibrosis. The current study provides evidence on the protective potential of tadalafil; a specific phosphodiesterase-5 (PDE-5) inhibitor against experimentally-induced pulmonary silicosis in rats. Silicosis was induced by intranasal instillation of crystalline silica (50mg/rat). Halofuginone hydrobromide; a standard collagen-1 synthesis inhibitor was selected as a reference anti-fibrotic. Daily oral administration of tadalafil (1mg/kg) for 8weeks significantly ameliorated silica-induced pulmonary damage...

INTRODUCTION: Sexual dysfunction is an important public health problem in men and is associated with reduced quality of life. It is more common in patients with schizophrenia. It is well-established that antipsychotic drugs cause sexual dysfunction with consequences on the quality of life of patients, adherence to treatment, and public health costs. Phosphodiesterase type 5 inhibitors (PDE5 inhibitors) are indicated for the management of erectile dysfunction. However, there is little information on such treatment in schizophrenic patients...

The aim of this research was to develop immediate release tablets comprising solid dispersion (IRSDTs) of tadalafil (Td) in a vinylpyrrolidone and vinyl acetate block copolymer (PVP-VA), characterized by improved dissolution profiles. The solid dispersion of Td in PVP-VA (Td/PVP-VA) in a weight ratio of 1:1 (w/w) was prepared using two different processes i.e. spray drying and ball milling. While the former process has been well established in the formulation of IRSDTs the latter has not been exploited in these systems yet...

BACKGROUND: Lower Urinary Tract Symptoms (LUTS) in men are a common clinical problem in urology and have been historically strictly linked to benign prostatic hyperplasia (BPH), which may lead to bladder outlet obstruction (BOO). New molecules have been approved and have entered the urologists' armamentarium, targeting new signaling pathways and tackling specific aspects of LUTS. Objective of this review is to summarize the evidence regarding the new medical therapies currently available for male non-neurogenic LUTS, including superselective α1-antagonists, PDE-5 inhibitors, anticholinergic drugs and intraprostatic onabotulinum toxin injections...

In this study, the suitability of high-energy ball milling was invesitaged with the aim to vitrify tadalafil (TD) and improve its bioavailability. To achieve this goal, pure TD as well as binary mixtures composed of the drug and Soluplus® (SL) were co-processed by high-energy ball milling. Modulated differential scanning calorimetry (MDSC) and X-ray powder diffraction (XRD) demonstrated that after such co-processing, the crystalline form of TD was transformed into an amorphous form. The presence of a single glass transition (Tg) for all the co-milled formulations indicated that TD was dispersed into SL at the molecular level, forming amorphous molecular alloys, regardless of the drug concentration...
