Tentex Royal Information

Introduction

Tentex Royal is a medication indicated for the treatment of erectile dysfunction (ED) in adult men. The active compound, also named Tentex Royal, belongs to the phosphodiesterase‑5 (PDE5) inhibitor class, which is the standard pharmacological approach for restoring erectile function. In Hong Kong, ED affects a substantial proportion of men over the age of 40, and access to effective, affordable therapy is an important public‑health concern. Tentex Royal offers a generic alternative that can be obtained through our online pharmacy, providing a cost‑effective option for patients seeking reliable treatment.

What is Tentex Royal?

Tentex Royal is the generic version of the original brand that contains the same active compound, Tentex Royal. It is manufactured by licensed pharmaceutical companies that follow Good Manufacturing Practice (GMP) standards. As a PDE5 inhibitor, Tentex Royal works by targeting the same biochemical pathway as other well‑known brand‑name ED drugs such as Viagra® (sildenafil) and Cialis® (tadalafil), but it is formulated without the premium branding cost. Our online pharmacy supplies this generic product as a validated, quality‑assured alternative for patients in Hong Kong.

How Tentex Royal Works

Penile erection is regulated by a balance between nitric oxide (NO)‑mediated vasodilation and the breakdown of cyclic guanosine monophosphate (cGMP). Sexual stimulation triggers the release of NO, which activates guanylate cyclase and raises intracellular cGMP levels. Elevated cGMP relaxes smooth muscle in the corpora cavernosa, allowing blood to fill the erectile tissue.

Tentex Royal inhibits the enzyme phosphodiesterase‑5, which is responsible for degrading cGMP. By blocking PDE5, the drug prolongs the presence of cGMP, enhancing smooth‑muscle relaxation and improving blood flow to the penis. The therapeutic effect typically begins within 30–60 minutes after oral administration, peaks at about 1–2 hours, and may last for up to 8 hours, depending on dose and individual metabolism. The compound is cleared primarily via hepatic metabolism, with a half‑life of approximately 4 hours.

Conditions Treated with Tentex Royal

• Erectile Dysfunction (ED) – The primary approved indication. ED prevalence in Hong Kong is estimated at 20–30 % among men aged 40 years and older, making effective pharmacotherapy a common clinical need.
• Secondary use in Pulmonary Arterial Hypertension (off‑label) – Though not formally approved for this indication, PDE5 inhibition can modestly reduce pulmonary vascular resistance; such use is limited to specialist settings and not routinely recommended in Hong Kong.

Tentex Royal improves erectile function by addressing the physiological deficit of insufficient cGMP, thereby enabling a natural sexual response when adequate stimulation is present.

Who is Tentex Royal For?

Tentex Royal is suitable for adult men who experience difficulty achieving or maintaining an erection sufficient for satisfactory sexual activity and who do not have contraindications to PDE5 inhibition. Typical candidates include:

• Men with organic or mixed (psychogenic + organic) ED.
• Individuals whose ED is associated with diabetes, hypertension, or atherosclerotic disease, provided cardiovascular status allows sexual activity.
• Patients who prefer an oral, on‑demand therapy rather than injectable or surgical options.

Tentex Royal is not appropriate for:

• Men taking nitrates (e.g., nitroglycerin) or nitric‑oxide donors, due to risk of severe hypotension.
• Patients with a history of non‑arteritic anterior ischemic optic neuropathy (NAION).
• Individuals with uncontrolled severe cardiovascular disease (e.g., recent myocardial infarction, unstable angina).

A thorough medical evaluation is required before initiating therapy.

Risks, Side Effects, and Interactions

Common

• Headache
• Facial flushing
• Nasal congestion
• Dyspepsia (indigestion)
• Visual disturbances (e.g., mild color tinting)

These events are usually mild, transient, and resolve without medical intervention.

Rare

• Priapism (prolonged erection lasting > 4 hours)
• Sudden hearing loss
• Severe hypotension, especially when combined with alpha‑blockers

Patients experiencing any of these should seek prompt medical attention.

Serious

• Myocardial infarction or stroke in patients with pre‑existing high cardiovascular risk (rare and typically related to underlying disease rather than the drug itself).
• Acute vision loss due to NAION (very rare).

Drug–Drug Interactions

• Nitrates (e.g., glyceryl trinitrate): Additive vasodilatory effect → potentially life‑threatening hypotension.
• Alpha‑adrenergic blockers (e.g., tamsulosin): May cause symptomatic blood pressure drops; dose titration is recommended.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): Increase Tentex Royal plasma levels → higher risk of adverse effects; dose reduction may be needed.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine): Decrease drug exposure → reduced efficacy.

Patients should disclose all concurrent medications, including over‑the‑counter products and herbal supplements, before starting Tentex Royal.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing: 50 mg taken orally with water, approximately 30–60 minutes before sexual activity. Depending on efficacy and tolerance, the dose may be increased to a maximum of 100 mg or decreased to 25
