Pulmonary hypertension (PH) is a group of diseases characterized by a progressive increase in pulmonary vascular resistance that leads to right ventricular failure and premature death. Pulmonary hypertension flows severe with a pronounced decrease of physical endurance and leads to heart failure.

There are various methods to overcome pulmonary hypertension but Canadian HealthCare Mall is going to describe you one by means of Sildenafil Citrate – the generic name of Viagra.

For pulmonary hypertension treatment, Sildenafil should be taken in a dose of 25 mg (1 pill) three times a day. Thus it is necessary to maintain the interval between pills in 6 – 8 hours. The maximum single dose is 50 mg of sildenafil. However, increasing dose from 25 mg to 50 mg should be only when indicated and there is good tolerability. Older people are taking sildenafil in ordinary dosage.

People with impaired renal function, also take Sildenafil at normal doses. However, if the drug is poorly tolerated, it is possible to reduce the dosage to 25 mg twice a day. In liver disease, presence usual Sildenafil dosage is used, but in case of intolerance development, it is necessary to reduce the dosing frequency for two times a day to 25 mg.

Sildenafil Overdose

In applying high doses (up to 800 mg or more) overdose may be observed. The higher the dose is – the more likely negative symptoms may develop, and the stronger they are expressed. Overdose is manifested:

  • hot flashes;
  • dizziness;
  • face redness;
  • a headache;
  • nasal congestion;
  • visual impairment;

Interaction with Other Drugs

Concomitant use of Sildenafil with drugs affecting isoenzyme CYP3A4 (for example, tetracycline, ketoconazole, erythromycin, cimetidine, saquinavir, ritonavir, etc.) leads to lengthening of action period.

If an antacid is taken singly and simultaneously with sildenafil (e.g. Gastal, Almagel), then there is no interaction between them.

Also, following drugs do not affect sildenafil efficacy:

  • Tolbutamide;
  • Warfarin;
  • antidepressants;
  • diuretics (diuretics);

Sildenafil enhances the effect of sodium nitroprusside, nitroglycerin, and other nitric oxide donors, therefore, it is not recommended for these drugs simultaneous use.

Sildenafil with blockers may cause a severe drop in blood pressure, which manifests itself in dizziness form.

  4. Rarely – develop more than one in ten thousand but less than one in a thousand. The intensity of side effects is usually mild or moderate.
