Viagra (sildenafil)." Pfizer US Pharmaceuticals, New York, NY. While the precise biological actions of sildenafil in the heart are not fully understood, the drug is known to work by stopping the action of an enzyme, called phosphodiesterase 5 (PDE5A), the researcher says.  This enzyme is involved in the breakdown of a key molecule, cyclic GMP, which helps control stresses and limit overgrowth in the heart.  PDE5A is also the biological pathway blocked in the penis by sildenafil to promote the relaxation of blood vessels and maintain erections.  Funding for this study was provided by the National Institutes of Health (NIH), the Peter Belfer Laboratory Foundation and the Bernard Family Foundation.  The makers of the drug had no involvement in the design or support of the research. Do not take Viagra if you are also using a nitrate drug for chest pain or heart problems. Twenty subjects received VIAGRA 50 mg, but only 19 subjects received matching placebo.

Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment Of Fertility Carcinogenesis Sildenafil was not carcinogenic when administered to rats for 24 months at a dose resulting in total systemic drug exposure (AUCs) for unbound sildenafil and its major metabolite of 29-and 42-times, for male and female rats, respectively, the exposures observed in human males given the Maximum Recommended Human Dose (MRHD) of 100 mg. The typical recommended starting dose of Levitra is 10 mg and dosages can range from 5 mg to 20 mg depending on desired response and adverse reactions. Due to age-differences in plasma protein binding, the corresponding increase in the AUC of free (unbound) sildenafil and its active N-desmethyl metabolite were 45% and 57%, respectively [see DOSAGE AND ADMINISTRATION, and Use In Specific Populations] Renal Impairment: In volunteers with mild (CLcr=50-80 mL/min) and moderate (CLcr=30-49 mL/min) renal impairment, the pharmacokinetics of a single oral dose of VIAGRA (50 mg) were not altered. When the patent expires, other drug companies can start manufacturing and selling a generic form of the drug.

Dosage Adjustments In Special Populations Consider a starting dose of 25 mg in patients > 65 years, patients with hepatic impairment (e.g., cirrhosis), and patients with severe renal impairment (creatinine clearance < 30 mL/minute) because administration of VIAGRA in these patients resulted in higher plasma levels of sildenafil [see Use in Specific Populations and CLINICAL PHARMACOLOGY].

Hepatic Impairment: In volunteers with hepatic impairment (Child-Pugh Class A and B), sildenafil clearance was reduced, resulting in increases in AUC (85%) and Cmax (47%) compared to age-matched volunteers with no hepatic impairment. Female Viagra takes about forty-five minutes to take effect and the effects last for four to six hours.
