Phosphodiesterase type 5 (PDE-5) inhibitors, or sildenafil, are widely used drugs for the treatment of erectile dysfunction and pulmonary hypertension ().
Erectile dysfunction is the inability to achieve or maintain a hard erection, characterized by the inability to maintain or sustain a firm erection for satisfactory sexual performance (). In pulmonary hypertension, erectile dysfunction can occur in two forms: progressive (PDE-1) and permanent (PDE-5).PDE-5is a type of PDE-5, which is involved in the production of nitric oxide, an enzyme that mediates sexual stimulation in pulmonary arterial hypertension (PAH).Sildenafil(brand name Cialis®), a prescription-only PDE-5 inhibitor, inhibits the PDE-5 enzyme, causing the production of nitric oxide, leading to the relaxation of the smooth muscle and, consequently, the vasodilation of pulmonary blood vessels ().Sildenafil citrate(brand name Tadalafil®), a PDE-5 inhibitor, is used for the treatment of pulmonary hypertension.
In the treatment of pulmonary hypertension, PDE-5 inhibitors, including sildenafil, can be effective in managing symptoms such as dyspnea, hypertension, and exercise-induced pulmonary hypertension (EIPH). The most common side effects of PDE-5 inhibitors include flushing, headache, and dyspnea.
In the management of pulmonary hypertension, sildenafil is the only PDE-5 inhibitor that is approved by the US Food and Drug Administration (FDA) to treat pulmonary hypertension (). The use of sildenafil as a pulmonary hypertension treatment is associated with an increased risk of cardiovascular (CV) thrombotic events and mortality ().
In the treatment of pulmonary hypertension, PDE-5 inhibitors may cause changes in blood pressure when used in combination with nitrates. This combination may increase the incidence of adverse events such as hypotension, syncope, or bradycardia. A recent meta-analysis of randomized controlled trials (RCTs) on PDE-5 inhibitors reported a significant increase in cardiovascular death and stroke in patients treated with PDE-5 inhibitors compared to those treated with placebo (). A meta-analysis of RCTs of PDE-5 inhibitors in the treatment of pulmonary hypertension reported similar results ().
The PDE-5 inhibitors, including sildenafil and tadalafil, are used to treat pulmonary hypertension and are often prescribed for pulmonary hypertension that is caused by PAH. However, it has been suggested that PDE-5 inhibitors may not be as effective in the treatment of pulmonary hypertension due to their pharmacokinetics, pharmacodynamics, and safety profiles (). In patients with PAH, the administration of PDE-5 inhibitors increases the risk of developing pulmonary hypertension, including in patients with chronic obstructive pulmonary disease (COPD) ().
Sildenafil and tadalafil have shown great benefits in the treatment of PAH and are considered a first-line therapy for the treatment of PAH. However, the effectiveness of these agents has not been evaluated for pulmonary hypertension. In the treatment of pulmonary hypertension, sildenafil has been found to be more effective than tadalafil in a few RCTs ().
In this study, we investigated the effectiveness of sildenafil (Tadalafil®) and tadalafil (Cialis®) in the treatment of pulmonary hypertension in a clinical setting. The study was conducted in a setting where patients with pulmonary hypertension were admitted to hospital for the evaluation and treatment of pulmonary hypertension ().
The study was a randomized controlled trial (RCT) with a double-blinded design. The protocol was approved by the Institutional Review Board of the National Cancer Institute (NICI), and written informed consent was obtained from each patient before enrollment. All patients provided written informed consent before enrollment in the study.
Sildenafil tablets, also known as Viagra, are widely used to treat erectile dysfunction (ED) in men. Unlike some other medications that may require sexual stimulation to work, such as alpha-blockers and antifibrotics, sildenafil works by increasing blood flow to the penis, which helps men achieve and maintain an erection. However, like all medications, sildenafil can have side effects, including headaches, flushing, and dizziness. Some common side effects of sildenafil include:
Some men may experience some side effects from sildenafil. These side effects usually go away on their own as the body adjusts to the medication. However, if you experience any unusual symptoms, such as chest pain, sudden vision or hearing loss, or an erection that lasts more than four hours, seek medical attention immediately.
