Tadalafil generic sildenafil tablets and vardenafil vs sildenafil: A review of patient-preference studies. Vincenzo Mirone, Ferdinando Fusco, Andrea Rossi, sildenafil 20 mg for sale Riccardo Sicuteri, Francesco Montorsi. Research output : Contribution to journal › Article.

The immediate objective of phosphodiesterase type 5 (PDE5) inhibitor treatment is to restore the ability of a man to achieve andor maintain an erection adequate for sexual intercourse.

As erectile dysfunction (ED) generally develops in the second half of life, the ultimate objective generally is not procreation, but quality of sexual life.

Indeed, ED is known to impair quality of life considerably; two-thirds of men report that ED has impaired their self-esteem and nearly a third claim that it has damaged the relationship with their partner.

It follows that the therapeutic success of PDE5 inhibition has an important subjective component, which is compounded by the subjective nature and complexity of sexual life in humans. This makes it very difficult for physicians to be certain that they have selected the optimal therapy for a couple, even after a thorough evaluation. The 2007 European Association of Urology Guidelines stress the importance of educating the patient and claim that 'the patient will choose the final drug after his own experience'.

However, PDE5 inhibitors are typically used twice a week, so a patient would have to spend ?3 months trying the various compounds and dosages to achieve adequate exposure to all three PDE5 inhibitors; this would seem an unrealistic strategy in normal clinical practice. The acknowledgement that the patient has an important role in therapeutic decisions for ED has fuelled interest in the concept of patient preference.

It has been established that patient preference depends on three factors, i.e.

age, duration of ED, frequency and dynamics of sexual relations, and the characteristics of their partners, e.g.

age, menopausal status and level of interest in sexual activity and medication profile. Medication features of interest include efficacy in terms of quality of erection, consistency of effects, rapid onset of action, long duration of action, side-effect profile and route of administration; drug costs must also be considered if the teva sildenafil price medicinal product is not reimbursed.

Tadalafil and vardenafil are among the most widely used drugs for erectile dysfunction, which affects nearly 19% of men over 20 y of age.

Older men also suffer from age-related bone loss resulting in crippling fractures. We show that in mice, both agents act on bone cells, resulting in the formation of new bone and reduced removal of old bone.

Because of this net gain in bone mass, we posit that tadalafil and vardenafil could be used for cotreating erectile dysfunction and osteoporosis in men of advancing age, as well as for treating osteoporosis in postmenopausal women. We recommend future clinical studies to establish the capability of these drugs to increase bone density and reduce fracture risk in humans. We report that two widely-used drugs for erectile dysfunction, tadalafil and vardenafil, trigger bone gain in mice through a combination of anabolic and antiresorptive actions on the skeleton.

Both drugs were found to enhance osteoblastic bone formation in vivo using a unique gene footprint and to inhibit osteoclast formation.

The target enzyme, phosphodiesterase 5A (PDE5A), was found to be expressed in mouse and human bone as well as in specific brain regions, namely the locus coeruleus, raphe pallidus, and paraventricular nucleus of the hypothalamus.

Localization of PDE5A in sympathetic neurons was confirmed by coimmunolabeling with dopamine ?-hydroxylase, as well as by retrograde bone-brain tracing using a sympathetic nerve-specific pseudorabies virus, PRV152.

Both drugs elicited an antianabolic sympathetic imprint in osteoblasts, but with net bone gain. Unlike in humans, in whom vardenafil is more potent than tadalafil, the relative potencies were reversed with respect to their osteoprotective actions in mice.

Structural modeling revealed a higher binding energy of tadalafil to mouse PDE5A compared with vardenafil, due to steric clashes of vardenafil with a single methionine residue at position 806 in mouse PDE5A. Collectively, our findings suggest that a balance between peripheral and central actions of PDE5A inhibitors on bone formation together with their antiresorptive actions specify the osteoprotective action of PDE5A blockade.

Vardenafil belongs to the class of medications called

phosphodiesterase

It does this by allowing a greater blood flow into the penis when a man taking the medication is sexually aroused. It works only with sexual stimulation and does not increase sexual desire.
