What It Is and How It Works
Sildenafil citrate belongs to a group of medications known as phosphodiesterase type 5 (PDE5) inhibitors. It works by blocking the PDE5 enzyme, which promotes the degradation of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum. The inhibition of this enzyme increases levels of cGMP, resulting in the relaxation of smooth muscle and enhanced blood flow to the penis during sexual stimulation, leading to an erection.
Indications / Uses
Sildenafil citrate is primarily indicated for the treatment of erectile dysfunction. It may also be used to treat pulmonary arterial hypertension (PAH) under the guidance of a healthcare provider. Using sildenafil for purposes other than these approved indications should only occur under clinician supervision.
Dosage Forms and Typical Dosing Considerations
Sildenafil is available in tablet form, typically in dosages of 25 mg, 50 mg, and 100 mg. The recommended starting dose for erectile dysfunction is generally 50 mg taken as needed approximately one hour before sexual activity, but it can be adjusted based on the individual\’s response and tolerance. Factors such as age, kidney and liver function, and other medications may influence the dosing decision.
How to Take It Correctly Step-by-Step
To ensure effective and safe use of sildenafil citrate, consider the following steps:
- Take the medication about one hour before intended sexual activity.
- It can be taken with or without food; however, high-fat meals may delay the onset.
- Do not take more than one dose in a 24-hour period.
- If a dose is missed (not applicable for occasional use), follow prescription instructions for regular PAH treatment.
- Store at room temperature away from moisture and heat.
- Avoid consuming large quantities of alcohol or grapefruit juice, as they can interact with the medication.
