Sildenafil is in a class of medications called phosphodiesterase (PDE) inhibitors. Sildenafil treats erectile dysfunction by increasing blood flow to the penis during sexual stimulation. Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily.
For erectile dysfunction, turtle.pics the recommended starting dose is 10mg taken at least 30 minutes before sexual activities, as needed. This can be increased to 20mg at a later date if the response is poor. Larger doses of Cialis, usually 40mg, are also used to treat pulmonary arterial hypertension. This condition involves high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness. All medications should be taken at least 30 minutes before sexual activity to allow them time to work effectively. As with other medication from this drug class, there may be drug interactions and certain foods, like grapefruit juice, should be avoided when taking Cialis tablets.
Absolute bioavailability of tadalafil following oral dosing has not been determined. The European Medicines Agency has waived the obligation to submit the results of studies in all subsets of the paediatric population in the treatment of the erectile dysfunction. There are limited data from the use of tadalafil in pregnant women. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/foetal development, parturition or postnatal development (see section 5.3). As a precautionary measure, it is preferable to avoid the use of CIALIS during pregnancy. The co-administration of PDE5 inhibitors, including tadalafil, with guanylate cyclase stimulators, such as riociguat, is contraindicated as it may potentially lead to symptomatic hypotension (see section 4.5).
Potential vitamins include vitamin B9 (folic acid), vitamin B3 (niacin), vitamin D, vitamin C
