Liver damage: Patients with mild liver damage (child Pugh a) do not need to adjust the dose; For patients with moderate liver injury (child Pugh b), the initial dose of vardenafil is recommended to be 5mg due to the decrease of clearance rate, and then it is gradually increased to 10mg according to the tolerance and efficacy; The pharmacokinetics of vardenafil in patients with severe liver injury (child Pugh C) has not been studied.

4. Renal damage: Patients with mild, moderate or severe renal damage do not need dose adjustment. The pharmacokinetics of vardenafil in dialysis patients has not been studied.

5. Drug combination: some patients take vardenafil and dexamethasone at the same time α- Receptor blockers may cause symptomatic hypotension. Only when the patient accepts α- Only when the patient's condition is stable, can the combination therapy be used.

Precautions for alcohol soluble vardenafil: as sexual activity is associated with a certain degree of heart risk, doctors should first consider the heart condition of patients with erectile dysfunction before taking any treatment. The vasodilative properties of vardenafil may lead to a temporary mild decrease in blood pressure. Patients with left ventricular outflow dysfunction, such as aortic stenosis and idiopathic hypertrophic subaortic stenosis, may be sensitive to vasodilators, including PDE5 inhibitors. Due to the potential cardiac risk, it is not recommended for patients with heart disease to use it. Therefore, drugs for erectile dysfunction cannot be used. A study of the effect of vardenafil on QT interval in 59 healthy male subjects showed that vardenafil at a therapeutic dose (10.5 mg) and an overdose (80 mg) resulted in prolonged QTc interval. This should be taken into account in the clinical application of vardenafil.
