What It Is and How It Works
Sildenafil citrate is classified as a PDE5 inhibitor. It works by relaxing the blood vessels in the penis, allowing increased blood flow during sexual arousal. This mechanism relies on the presence of nitric oxide, which is released in the corpus cavernosum during sexual stimulation.
While sildenafil helps achieve and maintain an erection, it does not increase sexual desire. It should be noted that sexual stimulation is required for sildenafil to be effective.
Indications / Uses
The primary use of sildenafil citrate Cenforce 100 mg is for the treatment of erectile dysfunction (ED) in men. It is also sometimes used off-label for pulmonary arterial hypertension (PAH), although this is under medical guidance and involves different formulations and dosing.
Dosage Forms and Typical Dosing Considerations
Sildenafil citrate is commonly available in tablet form, with dosages typically ranging from 25 mg to 100 mg. Cenforce 100 mg refers to the 100 mg strength of this medication.
Typical dosing for ED involves taking the medication orally, approximately 30 to 60 minutes before sexual activity, not exceeding one dose per day. Dosage adjustments may be necessary for individuals with kidney or liver impairments and older adults. Decisions about exact dosing should be made by a healthcare provider based on the individual\’s health status and other medications they may be taking.
How to Take It Correctly Step-by-Step
- Take sildenafil approximately 30 minutes to 1 hour before planned sexual activity.
- Swallow the tablet whole with water.
- Can be taken with or without food; however, a high-fat meal may delay its onset.
