Hezkue (Sildenafil)

Hezkue is indicated for specific medical conditions where increased blood flow to certain tissues is required, and it is prescribed by qualified healthcare professionals.

• Treatment of erectile dysfunction in adult males.
• Management of pulmonary arterial hypertension to improve exercise capacity.
• Adjunct therapy for certain cases of secondary erectile dysfunction.
• Off‑label use may be considered for high‑altitude pulmonary edema under specialist guidance.
• Use in combination with lifestyle modifications for patients with mild to moderate erectile dysfunction.
• May be prescribed when other phosphodiesterase‑5 inhibitors are not tolerated.

• Sildenafil works by selectively inhibiting the enzyme phosphodiesterase type 5 (PDE5) found in smooth‑muscle cells of the corpus cavernosum and pulmonary vasculature. Inhibition of PDE5 prevents the breakdown of cyclic guanosine monophosphate (cGMP), allowing cGMP levels to rise. Elevated cGMP leads to relaxation of smooth muscle and vasodilation, which enhances blood flow to the penis during sexual stimulation and reduces pulmonary arterial pressure.

Adverse reactions to Hezkue can vary in frequency and severity, ranging from mild to potentially serious events.

Common

• Headache
• Flushing
• Nasal congestion
• Dyspepsia or indigestion
• Visual disturbances such as color tint changes
• Dizziness or light‑headedness
• Rash or itching
• Nausea or vomiting
• Back pain or muscle aches
• Diarrhea

Serious

• Sudden loss of vision (non‑arteritic anterior ischemic optic neuropathy)
• Sudden loss of hearing
• Priapism lasting more than four hours
• Severe hypotension, especially when combined with nitrates
• Cardiac arrhythmia in patients with pre‑existing heart disease
• Severe allergic reaction (anaphylaxis)
• Myocardial infarction in patients with coronary artery disease

Before prescribing Hezkue, clinicians should evaluate several patient‑specific factors and contraindications to minimize risk.

• Known allergy to sildenafil or any tablet ingredients.
• Current use of nitrates or nitric‑oxide donors, which may cause severe hypotension.
• Severe uncontrolled high or low blood pressure.
• Recent stroke or heart attack within the past three months.
• Retinitis pigmentosa or other inherited retinal disorders.
• Severe liver impairment (Child‑Pugh class C).
• Diseases that increase priapism risk, such as sickle cell disease.

Hezkue may interact with other medicines, altering its effectiveness or increasing the risk of adverse events.

Avoid

• Nitrates (e.g., nitroglycerin, isosorbide dinitrate) because combined vasodilation can cause dangerous hypotension.
• Guanylate cyclase stimulators (e.g., riociguat) due to additive pulmonary vasodilatory effects.
• Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, ritonavir) which can raise sildenafil plasma concentrations.
• Alpha‑adrenergic blockers (e.g., prazosin) when taken concurrently may lead to symptomatic hypotension.

Use with caution

• Antihypertensive agents, especially those causing vasodilation, as additive blood pressure lowering may occur.
• Other PDE5 inhibitors or recreational drugs such as poppers (amyl nitrite) that can enhance vasodilatory effects.
• CYP3A4 inducers (e.g., rifampin, carbamazepine) which may reduce sildenafil exposure.
