Caverta Information

Introduction

Caverta is a prescription tablet that contains sildenafil, a phosphodiesterase‑5 (PDE5) inhibitor used primarily to treat erectile dysfunction (ED) in adult men. In Hong Kong, erectile dysfunction is a recognized health concern, affecting an estimated 10 % of men aged 40 years and older, and the availability of effective oral therapy is a key component of modern men’s health services. Caverta belongs to the therapeutic group “Erectile Dysfunction, Men’s Health” and is manufactured by a licensed pharmaceutical company that supplies the product to international wholesalers and, subsequently, to patients through regulated channels.

What is Caverta?

Caverta is an oral tablet formulated with the active pharmaceutical ingredient (API) sildenafil citrate. Sildenafil was originally developed by Pfizer and approved worldwide under brand names such as Viagra® and Revatio® (the latter for pulmonary arterial hypertension). Caverta is a generic formulation that delivers the same amount of sildenafil as the reference products, typically 25 mg, 50 mg, or 100 mg per tablet. The drug is classified as a PDE5 inhibitor and is listed on the Hong Kong Department of Health’s electronic medicines catalogue as a prescription‑only medication. While the exact manufacturer of Caverta is not publicly disclosed, the product is produced under Good Manufacturing Practice (GMP) conditions and is subject to quality verification by regulatory authorities in its country of origin before being imported.

How Caverta Works

Sildenafil works by selectively inhibiting the enzyme phosphodiesterase‑5, which is abundant in the smooth muscle cells of the corpus cavernosum. Under normal sexual stimulation, nitric oxide (NO) is released from endothelial cells and nerve terminals, activating guanylate cyclase and increasing cyclic guanosine monophosphate (cGMP) levels. Elevated cGMP relaxes smooth muscle, allowing increased blood flow into the penile tissue and producing an erection. By blocking PDE5, sildenafil prevents the breakdown of cGMP, thereby sustaining the vasodilatory response.

Onset of action typically occurs within 30–60 minutes after oral ingestion, with peak plasma concentrations reached at about 1 hour. The therapeutic effect can last 4–6 hours, although individual response varies with age, comorbidities, and concomitant medications. Sildenafil is metabolised principally by hepatic cytochrome P450 enzymes (CYP3A4 and CYP2C9), and its elimination half‑life is approximately 4 hours.

Conditions Treated with Caverta

• Erectile Dysfunction (ED): The primary approved indication. ED is defined as the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. Sildenafil restores erectile capacity in men whose condition is related to endothelial dysfunction, diabetes, hypertension, or psychological factors.
• Pulmonary Arterial Hypertension (PAH) (off‑label in Hong Kong): Although Revatio™ is the brand indicated for PAH, some clinicians prescribe sildenafil for this purpose because it induces pulmonary vasodilation. Use for PAH in Hong Kong requires specialist assessment and is not the routine scope of Caverta.

Epidemiologically, the Hong Kong Census reports that men aged 45–64 account for the largest proportion of ED patients seeking medical help, underscoring the relevance of accessible oral therapy such as Caverta.

Patient Groups Most Likely to Benefit

• Men aged 30 – 70 years with clinically diagnosed erectile dysfunction who have not responded adequately to lifestyle modification alone.
• Patients with diabetes mellitus or vascular disease where endothelial dysfunction impairs NO‑mediated erection.
• Individuals using nitrate therapy for angina should avoid sildenafil due to the risk of severe hypotension; therefore, they are not suitable candidates.
• Patients with severe hepatic impairment may require dose reduction; otherwise, they benefit similarly to the general population.

Contra‑indications include concurrent nitrate use, severe hypotension, recent stroke or myocardial infarction (within 6 weeks), and known hypersensitivity to sildenafil or any tablet excipients.

Risks, Side Effects, and Interactions

Common

• Headache
• Facial flushing
• Dyspepsia (indigestion)
• Nasal congestion
• Vision changes (e.g., a blue‑tinted visual field)

These effects are usually mild to moderate, transient, and resolve without medical intervention.

Rare

• Priapism (prolonged erection > 4 hours)
• Sudden hearing loss
• Severe skin reactions (e.g., Stevens‑Johnson syndrome)

Patients experiencing any of these symptoms should seek immediate medical review.

Serious

• Cardiovascular events (myocardial infarction, stroke) in patients with pre‑existing cardiac disease, especially when combined with nitrates.
• Life‑threatening hypotension when taken with potent vasodilators.

Drug‑Drug Interactions

• Nitrates (e.g., nitroglycerin, isosorbide dinitrate): additive vasodilatory effect → severe hypotension.
• Alpha‑blockers (e.g., tamsulosin, doxazosin): may cause symptomatic blood pressure drops; dose spacing of at least 4 hours is recommended.
• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin, ritonavir): increase sildenafil plasma levels → higher risk of adverse events; dose reduction is advised.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine): decrease efficacy; consider alternative therapy.

Patients must disclose all current medications, including over‑the‑counter products and herbal supplements, to their healthcare provider.

Practical Use: Dosing, Missed Dose, Overdose

• Starting dose: 50 mg taken as a single tablet approximately 30 minutes to 1 hour before anticipated sexual activity.
• Dose adjustments: Based on efficacy and tolerability, the dose may be reduced to 25 mg or increased to 100 mg. No more than one tablet should be taken within a 24‑hour period.
• Food considerations: A high‑fat meal can delay absorption and reduce peak concentration; patients may take the tablet with or without food, noting potential delay.
• Alcohol: Moderate alcohol consumption does not significantly alter efficacy, but excessive intake may exacerbate hypotension and dizziness.

Missed dose: If an erection does not occur, the tablet should not be retaken. Skip the missed dose and resume the normal schedule for the next sexual encounter.

Overdose: Symptoms may include intense headache, prolonged hypotension, visual disturbances, or priapism. Patients should seek urgent medical care; treatment is supportive, with attention to cardiovascular status and removal of the drug from the system if necessary.

• Is it legal to import Caverta for personal use in Hong Kong?
  Personal import of prescription medicines is permitted when the patient holds a valid prescription from a Hong Kong‑licensed practitioner, and the quantity does not exceed a three‑month supply. Our online pharmacy ensures all legal requirements are met before dispatch.

• Are there specific warnings for Asian patients taking sildenafil?
  Pharmacokinetic studies indicate that East Asian populations may experience slightly higher plasma concentrations of sildenafil at equivalent doses, potentially increasing the incidence of mild side effects. Clinicians often start with a 25 mg dose for patients who are older or have reduced hepatic function.

• Do formulations of Caverta differ between regions (e.g., US vs EU vs Asia)?
  The active ingredient, sildenafil citrate, is identical worldwide; however, excipients such as tablet binders and colorants may vary slightly to meet regional regulatory standards. These differences do not affect clinical efficacy.

• Can Caverta be used as part of a telemedicine treatment plan?
  Yes. Many Hong Kong clinicians provide remote consultations and issue electronic prescriptions. Our online pharmacy accepts these prescriptions and conducts a mandatory professional evaluation before dispensing.

• How long does it take for Caverta to be delivered after the order is placed?
  Express delivery typically arrives within 5–7 business days after payment confirmation, while standard airmail takes about 2–3 weeks, depending on customs clearance.

• What should I do if I experience a painful erection lasting more than four hours?
  This condition, known as priapism, requires immediate medical attention. Seek emergency care; delayed treatment can result in permanent erectile tissue damage.
