Fildena Pharmacokinetics

The absorption of Fildena, particularly Sildenafil 100mg, is rapid. Peak plasma concentrations appear within 30 to 120 minutes post-dose. It is extensively distributed throughout the body. The mean volume of distribution is 105 liters. Metabolism occurs primarily in the liver, catalyzed by cytochrome P450 enzymes. It metabolizes into an active metabolite, N-desmethylated Sildenafil. The elimination half-life ranges from three to five hours. Excretion happens through feces and urine.

The pharmacokinetics in the elderly differ. There is reduced clearance, leading to increased plasma concentrations. This necessitates dosage adjustments for optimal efficacy and minimized adverse effects. Renal impairment further alters clearance. Patients with severe impairment experience a 200% increase in AUC. Hepatic impairment also elevates Sildenafil exposure, cautioning against standard dosing.

Mechanism of Action of Fildena

Fildena functions by inhibiting phosphodiesterase type 5 (PDE5). This blockade prevents cyclic guanosine monophosphate (cGMP) degradation. The accumulation of cGMP results in smooth muscle relaxation. Enhanced blood flow occurs in the corpus cavernosum. This physiological process supports penile erection.

It requires sexual stimulation to be effective. Fildena alone will not induce an erection. The medication selectively targets PDE5 but may affect PDE6 in the retina. This affinity can cause visual disturbances. The selectivity is critical in minimizing non-specific actions. PDE5 inhibition is not continuous, as cGMP levels are regulated dynamically.

Fildena Contraindications

Fildena is contraindicated with nitrates or nitric oxide donors. This combination can cause severe hypotension. Patients with cardiovascular risk factors must exercise caution. The same applies to those with severe hepatic impairment or renal failure. Individuals with hereditary retinal disorders should avoid use due to possible visual side effects.

Additionally, those with hypersensitivity to Sildenafil or other ingredients should refrain. The potential for allergic reactions mandates precaution. Concomitant use with guanylate cyclase stimulators is also contraindicated. This amplifies risks associated with hypotension.

Guidelines for a Missed Dose

Missing a dose of Fildena typically poses minimal risk, as it is not intended for daily use. It is recommended as needed. If a dose is skipped, it should be taken when remembered, provided there is adequate time before the next sexual activity. Avoid doubling up to make up for the missed dose. It is essential to adhere to prescribed dosing frequencies to avert overdosing risks.

Patience is key; the medication should be given time to take effect. Overuse or mismanagement can compromise its safety profile. Understanding these principles aids in optimizing therapeutic outcomes.

Toxicity and Overdose Risks

Overdosing on Sildenafil 100mg can lead to serious adverse reactions. These include severe hypotension, syncope, and prolonged erections. Priapism necessitates immediate medical intervention to prevent permanent damage. Gastrointestinal disturbances like nausea and vomiting may occur.

Cardiovascular complications are among the most critical concerns. These require prompt attention. Supportive measures should be employed in case of overdose. Monitoring and symptomatic treatment form the cornerstone of management. Antidotes are not available, emphasizing the importance of preventive care.

Fildena Availability Over The Counter

Fildena is a prescription medication. It is not available over the counter due to its potential side effects and contraindications. Consultation with a healthcare professional is mandatory. This ensures that the patient is an appropriate candidate for therapy.

Prescribing guidelines exist to protect patient safety. Unsupervised use could result in unintended complications. Healthcare providers assess medical history, potential drug interactions, and patient-specific factors. Only after thorough evaluation can Fildena be prescribed.
