Chemical Structure
The core component of Viagra Professional is sildenafil citrate. This compound serves as a potent PDE5 inhibitor. Structurally, it comprises a pyrazolopyrimidinone core. The molecular formula is C22H30N6O4S. It binds effectively to PDE5, enhancing erectile function.
The crystalline form of sildenafil ensures stability and bioavailability. Its synthesis involves a precise sequence of reactions. These contribute to its effectiveness in promoting vasodilation. By targeting PDE5, it influences the smooth muscle tissue of the penile arteries.
Dosage Information
Viagra Professional is available in 50 mg and 100 mg doses. The prescribed dose varies based on individual needs. Physicians recommend starting with a lower dose. Adjustments depend on therapeutic response and tolerability.
The maximum recommended frequency is once daily. Patients should take the tablet approximately 30-60 minutes before intercourse. Consuming a high-fat meal might delay its action. Consistent timing aids in optimal absorption and efficacy.
Viagra Professional Precautions
Consider health conditions when using Viagra Professional. Avoid use with nitrates or nitric oxide donors. These combinations can lead to severe hypotension. Patients with cardiovascular risks require thorough assessment.
Caution is advised for individuals with anatomical penile deformations. Those with bleeding disorders or peptic ulcers should consult a healthcare provider. Monitoring is essential for those on alpha-blockers or other antihypertensive agents.
Pregnancy and Breastfeeding
Viagra Professional is not intended for use in women. Effects during pregnancy and lactation have not been thoroughly studied. No therapeutic benefits are known for these conditions. Consultation with a healthcare provider is crucial if unintended exposure occurs.
Sildenafil does not pass into breast milk significantly. However, its impact remains uncharted. While primarily a concern for male patients, awareness remains vital in specific scenarios.
Viagra Professional Side Effects
Common side effects include headaches, flushing, and nasal congestion. Some experience dizziness or visual disturbances. Severe reactions are rare but necessitate immediate medical attention. Such symptoms might include sudden hearing loss or an erection lasting more than four hours.
Adverse effects often decrease with continued use. Gradual acclimatization to the medication’s active compound occurs. Reporting persistent or worsening symptoms to a physician is advised.
Viagra Professional Over The Counter
Viagra Professional requires a prescription for purchase. Its procurement without a prescription is discouraged. This regulation ensures safe and appropriate use. Obtaining it over the counter could lead to misuse or contraindicated scenarios.
Consulting a healthcare provider before beginning treatment is crucial. They evaluate medical history and potential interactions. An informed approach fosters safe and effective therapy.
