Pharmacokinetics
The absorption of Viagra Professional 100 mg involves rapid onset. Peak plasma concentrations occur within 30 to 120 minutes post-administration. This medication showcases an average half-life of about four hours. The bioavailability of sildenafil in Viagra Professional stands at 40%. This level enables effective systemic circulation.
Distribution into tissues is comprehensive. Protein binding remains at approximately 96%. Sildenafil predominantly undergoes hepatic metabolism. The CYP3A4 enzyme plays a significant role. Consequently, drug interactions may arise from concurrent CYP3A4 inhibitors or inducers. Renal and fecal routes facilitate excretion. A major portion exits via feces. A lesser fraction leaves through urine.
Other Uses for Viagra Professional
While primarily indicated for erectile dysfunction, Viagra Professional harbors potential in treating pulmonary arterial hypertension (PAH). Sildenafil, the active compound, relaxes blood vessel walls. This effect can reduce blood pressure in lung arteries, easing heart workload.
Off-label, Viagra Professional has seen research in Raynaud’s phenomenon. By improving blood flow, it might reduce attacks. Similarly, its vasodilatory properties have inspired investigation into other vascular conditions. In such cases, consult a healthcare professional for suitability and dosing guidelines.
Who Can and Cannot Take Viagra Professional
Viagra Professional is intended for adult men facing erectile dysfunction. Candidates include those in stable physical health. The assessment by a qualified physician is crucial. This evaluation ensures the absence of contraindications.
Individuals with cardiovascular issues, or those on nitrates, should avoid it. Hypotension poses a risk when combined with other vasodilators. Patients with severe hepatic impairment must exercise caution. If allergies to sildenafil or its constituents exist, abstention is advised.
Viagra Professional Storage
Proper storage maintains efficacy. Viagra Professional 100 mg requires a cool, dry environment. The temperature should not exceed 30°C (86°F). Avoid exposure to moisture or direct sunlight. Keep tablets in their original packaging. This step safeguards against degradation.
Store away from children’s reach. Ensure the container is tightly sealed. Regular checks for expiration dates are advisable. Expired medication should be disposed of responsibly. Consult pharmacists for disposal guidance.
Toxicity
In overdose scenarios, sildenafil toxicity may manifest. Symptoms include dizziness, syncope, and prolonged erection. Visual disturbances might occur. Seek immediate medical attention if symptoms emerge.
Preclinical studies in animals demonstrated dose-dependent toxicity. Careful adherence to prescribed dosages minimizes risk. Avoid combining with other ED medications unless directed by a physician. Safety margins are established through rigorous clinical trials.
Viagra Professional Over The Counter
Viagra Professional is not available over the counter. Prescription-only status prevails due to potential side effects and contraindications. Professional medical advice ensures appropriate usage.
Online vendors may offer non-regulated alternatives. Caution is urged in such transactions. Authenticity and safety may not be guaranteed. Legal and health implications arise from acquiring prescription drugs without oversight.
