Pharmacokinetics
The pharmacokinetics of Viagra Plus (Sildenafil Citrate) are integral to its therapeutic effects. Sildenafil, the active agent, acts by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This leads to increased levels of cyclic guanosine monophosphate (cGMP), facilitating smooth muscle relaxation in the corpus cavernosum and promoting increased blood flow. Absorption occurs rapidly, with peak plasma concentrations achieved within 30 to 120 minutes. Its half-life is approximately 4 hours. Metabolism primarily involves hepatic pathways, with excretion through feces and urine.
How should Viagra Plus be used?
Viagra Plus should be administered as prescribed, usually an hour before anticipated sexual activity. The standard starting dose is Viagra Plus 50 mg. However, this can be adjusted to 100 mg or reduced to 25 mg, depending on efficacy and tolerability. Do not exceed the recommended dosage. A glass of water aids the ingestion process. Avoid high-fat meals around the time of consumption as they can delay the drug’s onset. Consult a healthcare provider for individualized advice and adherence to the prescribed regimen.
FDA-Approved Indications
Viagra Plus is approved by the FDA for treating erectile dysfunction (ED). Its efficacy in achieving and maintaining an erection suitable for sexual activity is well-documented. The drug is not indicated for use in women or children. Physicians may prescribe it off-label for other conditions under their discretion, ensuring the benefits outweigh potential risks.
Cautions with other medicines
Potential interactions between Viagra Plus and other medications require attention. Concomitant use with nitrates can cause a severe drop in blood pressure. Antihypertensives may exacerbate hypotensive effects. Caution is necessary with CYP3A4 inhibitors such as ritonavir and ketoconazole, which can elevate sildenafil levels. Disclose all current medications to your healthcare provider to avoid adverse interactions.
How to cope with side effects of Viagra Plus
Side effects of Viagra Plus may include headache, flushing, dyspepsia, and nasal congestion. These are generally mild and transient. To manage headaches, ensure adequate hydration and rest. Persistent or severe side effects necessitate medical consultation. Rarely, visual disturbances and priapism occur; immediate medical attention is vital in these scenarios.
Viagra Plus Over The counter
Viagra Plus is not available over-the-counter. It requires a prescription from a qualified healthcare professional. This ensures safe usage and proper monitoring of its effects. While some online sources claim to sell Viagra Plus without a prescription, these may pose significant health risks. Always seek reputable, regulated channels to obtain the medication safely.
