Clinical trials have subjected Cenforce D, an FDA-approved medication, to extensive testing. Sildenafil Citrate and Dapoxetine Hydrochloride are its active components. While sildenafil citrate activates the blood flow system, which results in a hard penile erection, Dapoxetine hydrochloride increases serotonin activity, which lengthens the time it takes to ejaculate and improves control over it. Cenforce D is an oral medication that needs to be taken exactly as prescribed, just like other prescriptions. You need to consider a few things to get the most out of the drug. Take the drug as prescribed; do not go beyond the suggested dosage or alter it on your own. It is a prescription drug that ought to be used exclusively.
