Pharmacokinetics of Fildena
Fildena, containing sildenafil citrate, exhibits precise pharmacokinetics. Administered orally, sildenafil is rapidly absorbed. Peak plasma concentrations appear within 30 to 120 minutes. Bioavailability is approximately 41%. A high-fat meal may delay absorption, reducing peak plasma concentration by nearly 29%. The volume of distribution is about 105 L, suggesting extensive tissue distribution.
The drug is predominantly metabolized in the liver. Cytochrome P450 3A4 is the main enzyme involved. The principal circulating metabolite is N-desmethylated. Fildena and its metabolites are primarily excreted via feces (approximately 80%) and to a lesser extent in urine (approximately 13%). Its terminal half-life is around 3 to 5 hours.
Mechanism of Action
Fildena’s active ingredient, sildenafil citrate, targets the phosphodiesterase type 5 (PDE5) enzyme. Inhibition of PDE5 increases cyclic guanosine monophosphate (cGMP) levels. This leads to smooth muscle relaxation and vasodilation in the corpus cavernosum. The physiological mechanism driving penile erection thus becomes effective.
Sexual stimulation triggers nitric oxide release. This facilitates cGMP production, essential for the vasodilation process. Fildena amplifies the natural erectile response by maintaining elevated cGMP levels. Its efficacy is contingent upon the presence of sexual arousal.
Who Can and Cannot Take Fildena
Fildena is approved for adult males with erectile dysfunction. Individuals seeking treatment should consult healthcare providers to confirm suitability. It’s contraindicated in those with hypersensitivity to sildenafil or any components.
Fildena should be avoided by individuals on nitrates due to potential hypotension. Caution is advised for patients with cardiovascular disorders, retinitis pigmentosa, or severe hepatic impairment. Women, children, and adolescents should not use Fildena.
Missed Dose
If a dose of Fildena 100 mg is missed, take it when remembered, before planned sexual activity. Do not double doses to compensate for missed instances. The medication is typically taken as needed, minimizing the likelihood of missing doses.
Adherence to prescribed dosing schedules maximizes therapeutic efficacy. Consult a healthcare professional for further guidance on missed doses.
Toxicity of Fildena
Overdose of Fildena can lead to increased adverse effects. Symptoms may include severe dizziness, syncope, priapism, or vision disturbances. Seek immediate medical attention if overdose is suspected.
Maintain awareness of drug interactions, particularly with alpha-blockers and other PDE5 inhibitors. Safety profiles of higher doses should be scrutinized through professional medical advice.
