    Revatio vs viagra


    Viagra (sildenafil) and Levitra (vardenafil) are prescription medications used to treat erectile dysfunction and pulmonary arterial hypertension. Viagra was introduced by Pfizer Pharmaceuticals in March 1998 as a treatment for pulmonary arterial hypertension. The clinical trials revealed that the active ingredient — generically known as sildenafil citrate — also relaxed the muscle tissues in the penis, allowing for increased blood flow. Levitra, introduced in 2003 by Bayer Pharmaceuticals and marketed by Glaxo Smith Kline to treat erectile dysfunction, works similarly. In appearance, Viagra tablets are blue, rounded diamonds that are available in 25 mg, 50 mg, and 100 mg doses. Levitra has orange-colored tablets in 2.5 mg, 5 mg, 10 mg, and 20 mg doses. It is recommended that both medications be taken 30 to 60 minutes before sexual activity is intended. Viagra, Cialis, Levitra, and generic sildenafil are all part of a family of drugs called PDE-5 inhibitors. These drugs are used to treat erectile dysfunction (ED). Erectile dysfunction medication works by preventing the chemical process that lets blood leave an erect penis. Basically, PDE-5 inhibitors tip the chemical balance in the penis to favor getting and maintaining an erection. The biggest difference between Viagra and generic sildenafil is the amount of active ingredient in each pill. The other main difference is that generic sildenafil is FDA approved to treat Pulmonary Hypertension (that’s high blood pressure between the heart and lungs) while Viagra is FDA approved to treat erectile dysfunction. It’s a little confusing since both medications use the same active ingredient, but Viagra and sildenafil work in the same way.

    Phosphodiesterase type 5 inhibitors or PDEV inhibitors work by inhibiting or decreasing the effect of phosphodiesterase type 5, a substance that breaks down nitric oxide allowing for higher concentrations of nitric oxide to remain in the blood vessels. Nitric oxide is a potent vasodilator (opens up the blood vessels allowing blood to flow more easily through) and is deficient in the pulmonary blood vessels of pulmonary hypertension patients. The FDA (Food and Drug Administration) has approved two PDEV inhibitors for the treatment of PAH. Revatio is a PDEV inhibitor available in a 20mg pill form. This drug has another name, Viagra, and is used to treat erectile dysfunction. Before the FDA approved Revatio for the use of PAH, physicians were writing for Viagra for PAH patients. This prompted a huge number of phone calls from concerned pharmacists wondering why a physician was ordering a drug for erectile dysfunction for female patients. Among erectile dysfunction (ED) medications now stands a newer, lesser-known medication called Revatio. You may have heard of it recently, but don’t know much about it. Revatio, like Viagra, contains sildenafil, a chemical that increases blood flow throughout the body. ED medications like Revatio and Viagra use sildenafil to target lack of blood flow specifically to the penis before and during intercourse. Because of sildenafil’s ability to do this, it has remained the staple component in most ED medications since the FDA approved Viagra back in 1998. While Viagra and Cialis have dominated the commercial market, Revatio may prove another viable option to help treat your ED. The main similarity between Revatio and Viagra is the fact that sildenafil is the active ingredient. Interestingly, there is no mention of the fact that it can be used as an impotence medication on the official site, despite the fact that it contains the same chemical as Viagra. Everyone is familiar with the iconic blue, diamond shaped Viagra pill.

    After becoming almost completely blind due to what she says was a side effect of her acne medication, this teenager from Indiana is sharing a message of acne positivity. Clear skin has been put up on a pedestal, well, forever. But it's a beauty standard that can have serious mental health effects. As previously reported, studies have shown a compelling connection between acne and heightened risk of depression. There's no doubt struggling with acne can rob you of your self-worth, but for 19-year-old Emma O' Mahoney, it may have also almost completely robbed her of her vision. O' Mahoney dealt with acne, and its effects, throughout her teens. "I had very little self-worth and no confidence in my appearance," O' Mahoney tells .

    The dose in immunocompromised patients is 1000 mg three times daily for at least seven days (3000 mg total daily dose) and for 2 days following crusting of lesions. This dose should be reduced according to creatinine clearance (see Renal impairment below). For recurrent episodes, treatment should be for three to five days. For initial episodes, which can be more severe, treatment may have to be extended to ten days. For recurrent episodes of herpes simplex, this should ideally be during the prodromal period or immediately upon appearance of the first signs or symptoms. Valtrex can prevent lesion development when taken at the first signs and symptoms of an HSV recurrence. For herpes labialis (cold sores), valaciclovir 2000 mg twice daily for one day is effective treatment in adults and adolescents. The second dose should be taken about 12 h (no sooner than 6 h) after the first dose. Valtrex Tablets 500mg - Summary of Product Characteristics SmPC.
