Fildena: Mechanism of Action
Fildena, a popular medication for erectile dysfunction (ED), is powered by the active component sildenafil citrate. This compound belongs to the phosphodiesterase type 5 (PDE5) inhibitors class. PDE5 inhibitors block the enzyme PDE5, which degrades cGMP in the body. cGMP is vital for regulating blood flow in the penis.
During sexual stimulation, nitric oxide (NO) is released into the penile tissue. NO increases the production of cGMP, leading to the relaxation of smooth muscle cells. This results in enhanced blood flow to the penile area, facilitating an erection. By inhibiting PDE5, Fildena increases cGMP levels, ensuring the desired physiological response to sexual arousal.
It’s important to note that Fildena doesn’t act as an aphrodisiac. The drug requires sexual stimulation to initiate its effects. Its onset time is generally between 30 to 60 minutes, with a potential duration of up to four hours.
Fildena Precautions to Consider
Patients must exercise caution when using Fildena 100 mg or any other dosage. Prior to commencing treatment, a thorough medical evaluation is recommended. Individuals with cardiovascular issues, liver or kidney disease, and those with a history of stroke should consult healthcare providers. The drug might exacerbate underlying health conditions.
Fildena’s interaction with nitrate medications can cause a severe drop in blood pressure. This combination is contraindicated. Patients with known hypersensitivity to sildenafil or any other component of the tablet should avoid usage. Adverse reactions, such as dizziness or impaired vision, may impair the ability to drive or operate machinery.
Pregnant or breastfeeding women should not use Fildena. Though it primarily targets male sexual dysfunction, understanding contraindications and precautions is vital for safe administration.
Fildena and Drug Interactions
Combining Fildena 150 mg with certain medications can alter its effectiveness or increase side effects. Nitrates, often used for angina, must be avoided due to the risk of hypotension. Alpha-blockers, used for high blood pressure or prostate issues, may also interact adversely.
Medications such as ketoconazole and ritonavir, strong CYP3A4 inhibitors, can elevate sildenafil levels in the blood. This necessitates dosage adjustments. Other interactions include those with antibiotics like erythromycin and rifampicin, which can either increase or decrease sildenafil’s plasma concentration.
Medication | Interaction Effect |
---|---|
Nitrates | Severe hypotension |
Alpha-blockers | Increased risk of hypotension |
Ketoconazole | Elevated sildenafil levels |
Erythromycin | Altered plasma concentration |
Fildena: Signs and Symptoms of Overdose
Exceeding the recommended dosage of Fildena 200 mg can lead to significant adverse effects. Overdose symptoms may include severe dizziness, fainting, or a prolonged erection lasting more than four hours (priapism). This condition necessitates immediate medical attention to prevent tissue damage.
Other symptoms of overdose might include blurred vision, nausea, chest pain, or irregular heartbeat. In such scenarios, seeking urgent medical intervention is crucial. Continuous monitoring and supportive care form the primary approach to managing overdose cases.
Patients should adhere to prescribed dosages and avoid self-medication or dosage adjustment without medical advice. Understanding the dangers of overdose helps ensure the safe use of Fildena.
Non-Prescription Fildena Availability
Fildena, including its various dosages like Fildena 50 mg, is primarily available by prescription. This regulation ensures proper medical oversight and reduces misuse risk. Some online platforms claim to offer non-prescription variants. However, such sources might compromise quality and safety.
Purchasing from reputable sources, backed by a healthcare professional’s guidance, remains the safest approach. Regulatory bodies maintain oversight to ensure product authenticity and efficacy. Patients must remain vigilant against counterfeit medications in the market.
The regulatory landscape varies across regions. Some areas impose stricter controls, while others may have lenient policies. Regardless, professional consultation is invaluable in making informed decisions regarding Fildena usage.
- Fildena requires medical oversight.
- Prescription safeguards against misuse.
