Pharmacological action of
Tadalafil is a reversible selective inhibitor of specific type 5 phosphodiesterase (PDE-5) cyclic guanosine monophosphate (cGMP). When sexual arousal causes local release of nitric oxide, inhibition of PDE-5 by tadalafil leads to an increase in the concentration of cGMP in the cavernous body of the penis. The consequence of this is the relaxation of the smooth muscles of the arteries and the flow of blood to the tissues of the penis, which causes an erection.
In vitro studies have shown that tadalafil is a selective PDE-5 inhibitor. PDE-5 is an enzyme present in the smooth muscles of the cavernous body, blood vessels and internal organs, in skeletal muscles, platelets, kidneys, lungs and cerebellum. The effect of tadalafil on PDE-5 is more active than on other phosphodiesterases.
Tadalafil is 10,000 times more potent with respect to PDE-5 than with other types of phosphodiesterase (PDE-1, PDE-2, PDE-4 and PDE-7), which are localized in the heart, brain, blood vessels, liver, white blood cells and other organs. Tadalafil is 10,000 times more active in blocking PDE-5 than PDE-3, an enzyme that is found in the heart and blood vessels. This selectivity for PDE-5 compared to PDE-3 is important because PDE-3 is an enzyme involved in the contraction of the heart muscle.
In addition, tadalafil is approximately 700 times more active in relation to PDE-5 than PDE-6, which is found in the retina and is responsible for photo transmission. The action of tadalafil in relation to PDE-5 is 9000 times more pronounced than its effect on PDE-8, PDE-9 and PDE-10, and 14 times more pronounced than on PDE-11. The distribution in tissues and the physiological effects of the inhibition of PDE-8 - PDE-11 have not yet been clarified.
Tadalafil in healthy volunteers does not cause a significant change in systolic and diastolic blood pressure compared to placebo in the supine position (average maximum decrease is 1.6 and 0.8 mmHg, respectively) and in the standing position (average maximum decrease is 0 , 2 and 4.6 mmHg, respectively).
Tadalafil does not cause a significant change in heart rate.
Tadalafil does not cause color recognition changes (blue / green), due to its low affinity for PDE-6. In addition, there is no effect of tadalafil on visual acuity, electroretinogram, intraocular pressure and pupil size.
Several studies have been conducted to evaluate the effect of daily tadalafil on spermatogenesis. None of the studies showed an undesirable effect on sperm morphology and motility. One study found a decrease in mean sperm concentration compared to placebo.
A decrease in sperm concentration was associated with a higher frequency of ejaculation. Moreover, when comparing tadalafil with placebo, there was no undesirable effect on the average concentration of sex hormones (testosterone, luteinizing hormone and follicle-stimulating hormone).
Erectile Dysfunction (ED)
In our studies, tadalafil showed a statistically significant improvement in erectile function and the ability to have full sexual intercourse. Tadalafil has no effect in the absence of sexual arousal.
The efficacy and safety of tadalafil has been studied in clinical trials. An improvement in erection in patients with ED of all degrees of severity was observed when taking 5 mg of tadalafil once a day for 36 hours after administration, as well as maintaining an erection for 16 minutes after administration compared with placebo.
In studies of primary efficacy of 5 mg of tadalafil, 57% and 67% of attempts at sexual intercourse were successful compared with 31% and 37% with placebo. In studies of patients with secondary ED on the background of diabetes mellitus, 41% of attempts at sexual intercourse were successful compared to 28% with placebo.
Benign prostatic hyperplasia (BPH)
In patients with BPH, tadalafil, by inhibiting PDE-5, leads to an increase in the concentration of cGMP not only in the cavernous body of the penis, but also in the smooth muscles of the prostate, bladder and blood vessels that supply them. This in turn increases blood perfusion in these organs and, as a result, reduces the severity of symptoms of BPH.
Relaxation of the smooth muscles of the prostate and bladder and inhibition of the afferent innervation of the bladder can further enhance vascular effects.
Clinical studies have shown a decrease in symptoms of BPH within 1 week after taking 5 mg of tadalafil compared to placebo.
In studies involving patients with ED and symptoms of BPH with 5 mg of tadalafil, 71.9% of attempts at sexual intercourse were successful compared to 48.3% with placebo, and there was a significant improvement in erectile function and a decrease in symptoms of the prostate gland .

5-alpha reductase inhibitors - predisposition to priapism (with sickle cell anemia, multiple myeloma or leukemia), anatomical deformation of the penis (angular curvature ny, cavernous fibrosis or Peyronie's disease).
Special instructions
Diagnosis of ED and BPH should include identification of the underlying cause of the disease, appropriate medical examination, determination of treatment tactics and an individual assessment of the benefit / risk ratio.
Sexual activity has a potential risk for patients with cardiovascular disease, therefore, treatment of ED should not be carried out in men with heart diseases in which sexual activity is not recommended.
Like other PDE-5 inhibitors, tadalafil can have a systemic vasodilator effect, which can lead to a transient decrease in blood pressure and an increase in the hypotensive effect of nitrates, alpha-blockers. Before prescribing the drug, it is necessary to carefully assess the likelihood of such adverse reactions in patients with cardiovascular disease.
Patients with a suspected diagnosis of BPH should be screened to rule out prostate cancer.
Non-arterial anterior ischemic optic neuropathy (NAPION) is a cause of visual impairment, including complete loss of vision. There are rare post-marketing reports of cases of development of NAPION, in time associated with the intake of PDE-5 inhibitors. It’s currently not possible to determine Is there a direct connection between the development of NAPION and the intake of PDE-5 inhibitors or other factors.
Patients should be warned that in the event of a sudden loss of vision, stop taking tadalafil and seek medical help. Patients should also be informed that people who have undergone NAPION have an increased risk of re-developing NAPION.
Priapism has been reported with PDE-5 inhibitors, including tadalafil. Patients should be informed about the need to immediately seek medical help in case of an erection lasting 4 hours or more. Untimely treatment of priapism leads to damage to the tissues of the penis, resulting in irreversible impotence.
The effectiveness of the drug in patients undergoing surgery on the pelvic organs or radical nerve-sparing prostatectomy, is unknown.
Impact on the ability to drive transp. Wed and fur .:
Despite the fact that the incidence of dizziness against placebo and tadalafil is the same, during treatment, care must be taken when driving vehicles and engaging in other potentially dangerous activities that require an increased concentration of attention and speed of psychomotor reactions.
Patients should be aware of the possible development of drowsiness when taking the drug, especially at the beginning of therapy or in combination with alcohol.
