Sildenafil belongs to a group of medicines called phosphodiesterase 5 (PDE5) inhibitors. These medicines prevent an enzyme called phosphodiesterase type-5 from working too quickly.
12.1 Mechanism of Action
In clinical trials, sildenafil showed significant effects on erectile response 60 minutes after the dose was taken, though the effects may be evident within 30 minutes. For pulmonary hypertension, sildenafil lowers blood pressure about one to two sildenafil 50 mg tab hours after a dose is taken. With a half-life of four hours, sildenafil and its active metabolite are completely cleared from the system in about 20 hours, though the effects fade before then. For erectile dysfunction, sildenafil produces its maximum effects for about two hours and can still produce an erectile response four hours after a dose is taken. For pulmonary hypertension, sildenafil’s benefits in lowering blood pressure were the same as a placebo (inert pill) after eight hours.
2.1 Dosage Information
For treatment of erectile dysfunction, take only one dose per day. If a dose has been forgotten, take it when remembered but wait at least 30 minutes before attempting sexual activity. For pulmonary hypertension, take a missed dose as soon as you remember it. If it’s almost time for the next dose, skip the missed dose and take the next dose as scheduled. If too much sildenafil is taken, get immediate medical attention. The penis is one of the areas where this enzyme works.
- The usual starting dose of sildenafil for ED is 50 mg, but 20 mg may be prescribed for some patients.
- Prescription requirements ensure safe usage and proper dosing based on health conditions.
- Always follow a doctor’s instructions when taking sildenafil 20 mg.
Erectile dysfunction is a condition where the penis does not harden and expand when a man is sexually excited, or when he cannot keep an erection.
