Cialis Professional

Cialis Professional is a prescription-only medication approved for the treatment of erectile dysfunction (ED) in adult men. The product contains the phosphodiesterase-5 (PDE5) inhibitor tadalafil, a compound that has been available in various formulations worldwide for over two decades. In Singapore, the professional-grade tablet is marketed in 20 mg and 40 mg strengths and is intended for use under the guidance of a qualified healthcare professional. While its primary purpose is to improve erectile function, the drug’s pharmacological profile also supports use in benign prostatic hyperplasia (BPH) when prescribed appropriately.

What is Cialis Professional?

Cialis Professional belongs to the class of PDE5 inhibitors, a group of oral agents that enhance nitric-oxide signaling in the penile tissue. Developed by Eli Lilly and approved by health authorities across many regions, this brand is distinguished by its higher-strength tablets, which allow clinicians to tailor therapy to individual response and durability needs. The FDA, EMA and Singapore’s Health Sciences Authority recognize tadalafil-containing products as safe and effective when used according to prescribing information. Generic versions of the same active ingredient are widely available, offering comparable bioavailability at reduced cost; nevertheless, many patients choose the brand formulation for its consistent manufacturing standards and established clinical track record.

How Cialis Professional Works

The physiological cascade leading to an erection begins with sexual stimulation, which triggers the release of nitric oxide (NO) from nerve endings and endothelial cells within the corpus cavernosum. NO activates guanylate cyclase, an enzyme that converts guanosine-triphosphate (GTP) into cyclic guanosine-monophosphate (cGMP). Elevated cGMP relaxes smooth muscle, permitting blood to fill the erectile chambers. In a resting state, the enzyme phosphodiesterase-5 rapidly degrades cGMP, curtailing the erection.

Tadalafil selectively blocks PDE5, thereby preserving cGMP levels for a prolonged period. The resulting smooth-muscle relaxation sustains penile inflow and improves rigidity. Oral absorption of tadalafil is quick; peak plasma concentrations appear within 2 hours, and the drug’s half-life of approximately 17.5 hours accounts for its “long-acting” reputation. Metabolism occurs primarily via the cytochrome P450 3A4 pathway, with renal and biliary excretion handling the inactive metabolites. This pharmacokinetic profile explains why a single dose can support sexual activity for up to 36 hours, giving patients a broader window of spontaneity compared with shorter-acting PDE5 inhibitors.

Cialis Professional is Used for Sexual Health Conditions

Erectile Dysfunction

Erectile dysfunction arises when the NO-cGMP pathway fails to generate sufficient smooth-muscle relaxation. Clinical trials involving men with varying severity of ED have demonstrated that tadalafil increases successful penetrative intercourse rates by roughly 30 % compared with placebo. The drug’s ability to maintain therapeutic cGMP levels throughout the day translates into reliable erections without the need to time the dose precisely before sexual activity. Guidelines from the American Urological Association and Singapore’s Ministry of Health endorse tadalafil as a first-line oral therapy for men whose ED is not resolved by lifestyle modification alone.

Benign Prostatic Hyperplasia

While the primary indication for Cialis Professional in Singapore is ED, tadalafil’s smooth-muscle relaxant properties also relieve lower-urinary-tract symptoms associated with BPH. By inhibiting PDE5 in the prostate and bladder neck, the medication reduces urinary frequency, nocturia, and weak stream. Randomized studies of daily 5 mg dosing have shown clinically meaningful improvements in International Prostate Symptom Score (IPSS) values, supporting its dual-use recommendation in men who experience both ED and BPH.

Pulmonary Arterial Hypertension (Investigational Context)

Tadalafil, at higher doses, has been evaluated for pulmonary arterial hypertension (PAH) because PDE5 is expressed in pulmonary vascular smooth muscle. Although the 20 mg and 40 mg strengths marketed for sexual health are not approved for PAH in Singapore, research suggests that chronic PDE5 inhibition can lower pulmonary artery pressure and improve exercise capacity. Such off-label exploration remains confined to specialist settings and must follow strict monitoring protocols.

Off-Label and Investigational Uses of Cialis Professional

Beyond its approved roles, clinicians occasionally consider tadalafil for conditions where PDE5 activity contributes to disease pathology. Small-scale studies have reported modest benefit in treating Raynaud’s phenomenon, where vasospasm of peripheral arteries leads to digital ischemia. By promoting vasodilation, tadalafil may reduce frequency of attacks, although evidence is not yet robust enough for guideline endorsement. Additionally, anecdotal reports describe its use in promoting erectile function after prostatectomy, but randomized data remain limited. Off-label use only under qualified healthcare provider supervision.

Is Cialis Professional Right for You?

Candidate selection hinges on a comprehensive medical assessment. Men with a confirmed diagnosis of ED who have not responded adequately to lifestyle measures or who desire a flexible timing window often find tadalafil advantageous. Those with concurrent BPH may benefit from the drug’s dual action. Conversely, patients with a history of severe cardiovascular events, uncontrolled hypertension, or recent use of nitrates should avoid PDE5 inhibition due to the risk of profound hypotension. Individuals with severe hepatic impairment may experience altered drug clearance, prompting dose adjustment or alternative therapy. Women, children and adolescents are not eligible for this indication. In special populations such as the elderly, clinicians typically start at the lower 20 mg dose to gauge tolerance before considering escalation.

Taking Cialis Professional Effectively

Optimal use begins with swallowing the tablet whole with a glass of water. Food does not markedly alter tadalafil absorption, yet a high-fat meal may delay onset by up to two hours; patients seeking rapid effect often schedule dosing on an empty stomach. The medication can be taken either as needed-once per 24-hour interval-or, under physician direction, as a daily low-dose regimen for continuous symptom control. When a dose is missed, the patient should forgo a double-dose and resume the regular schedule at the next appropriate time. Consistency in timing, coupled with a reminder system (phone alarm, medication app), helps maintain therapeutic levels and reduces missed-dose anxiety. Patients planning international travel should retain the prescription label and be aware that Singapore customs permits a maximum 30-day supply for personal use.

Understanding Side Effects and How to Manage Them

Adverse reactions arise primarily from the drug’s vasodilatory action. Commonly reported sensations include mild headache, facial flushing, nasal congestion, and transient dyspepsia. These effects reflect peripheral blood-vessel dilation and typically resolve without intervention within a few hours. Patients can mitigate headache by ensuring adequate hydration and, if needed
