2. Instructions for taking sildenafil:

 

(1) Sildenafil should be used under the guidance of a medical practitioner.

(2) Patients who have had stroke and heart attack, hypotension, or some rare hereditary eye diseases and pigmented optic motitis are contraindicated.

(3) Sildenafil is contraindicated with NO donors because of reports of severe hypotension resulting from sildenafil contraindication with NO donors.

(4) Sildenafil is contraindicated in patients with a history of serious cardiovascular disease and who are not suitable for sexual activity and severe liver damage.

 

3. Side effects of sildenafil:

 

1. Headache. Clinical trials have found that about 1% of people get headaches with higher doses.

2. Dazzling. About 0.3 percent of those taking the drug experienced temporary blurred vision, and some had hallucinations of seeing blue light.

3. Faint. May cause a sudden drop in blood pressure, such as taking drugs at the same time, often immediately faint or even faint.

4. Mask cardiovascular disease. Impotence can be a sign of heart disease, diabetes or cancer, and taking the drug can mask the true condition.

 

4. Sildenafil references:

 

Sildenafil citrate, suitable for capsules, tablets. Take it about 1 hour before sexual activity as needed, and sexual stimulation is required after taking it. However, it can be taken at any time within 0.5 ~ 4h before sexual activity. Based on the efficacy and tolerance, the daily dose can be adjusted between 50 ~ 120mg, and the medication should not be taken more than once a day. Studies have shown that when a single dose of 800mg is increased in healthy volunteers, adverse reactions are similar to those at lower doses, but the incidence increases. When overdosing, routine supportive therapy should be used as needed. Because sildenafil binds to plasma proteins at a high rate and is not cleared from urine, hemodialysis does not increase clearance.

 

Sildenafil is absorbed quickly after oral administration, and takes effect in 10 ~ 40 minutes. The bioavailability is about 40%. The peak plasma concentration (Cmax) was reached 30 ~ 120min after fasting oral administration, and 90 ~ 180min after postprandial oral administration. The blood concentration and cmax were 2ng/ml and 440ng/ml respectively 24h after oral administration of 100mg in healthy volunteers. Increased area under curve (AUC) in patients with abnormal liver function, severe renal insufficiency or over 65 years of age. About 96% of sildenafil and its main circulating metabolite (n-demethylated) bind to plasma protein, and the protein binding rate is independent of the total drug concentration. The tissue was well distributed and the distribution volume (Vd) was 105L. Sildenafil is primarily cleared by the liver microsomal enzyme cytochrome P450 3A4 (CYP 3A4, the primary pathway) and cytochrome P450 2C9 (CYP 2C9, a secondary pathway). Its main metabolite (n-demethylated) has a PDE selectivity similar to that of sildenafil, and its plasma concentration is about 40% of that of sildenafil, so about 20% of sildenafil's pharmacological effects are due to its metabolites. The elimination half-life of sildenafil and its metabolites is about 4h, 80% of the dose is excreted mainly in the form of metabolites through feces and 13% through kidney. Sildenafil was less than 0.001% of the dose in serum of healthy volunteers 90 minutes after administration.
