Cialis 5mg Once-A-Day is a prescription-only oral medication containing the active pharmacological agent Tadalafil. Unlike on-demand phosphodiesterase type 5 (PDE5) inhibitors, this low-dose daily formulation is designed to maintain consistent systemic levels of the active compound. It is clinically indicated for the treatment of adult men experiencing Erectile Dysfunction (ED) and for the management of the lower urinary tract symptoms (LUTS) associated with Benign Prostatic Hyperplasia (BPH).
Key Medical Benefits & Clinical Value
1. Continuous Therapeutic Efficacy for Erectile Dysfunction (ED)
By adopting a daily dosing regimen of 5mg, patients achieve a steady-state plasma concentration of Tadalafil within five days. This continuous therapeutic window:
Eliminates the necessity of planning medical intake prior to sexual activity.
Reduces the psychological anxiety associated with strict treatment windows.
Restores natural, spontaneous erectile response when combined with physical or psychological sexual stimulation.
2. Alleviation of Benign Prostatic Hyperplasia (BPH) Symptoms
BPH causes progressive urinary discomfort due to prostate enlargement. Daily administration of low-dose Tadalafil is clinically proven to:
Relax the smooth muscle tissues of the bladder neck and prostate gland.
Improve urinary flow rates and minimize painful or strained micturition (urination).
Reduce the frequency of nocturia (waking up during the night to urinate) and daytime urgency.
3. Dual-Action Therapy for Co-existing Conditions
For patients suffering from both ED and BPH simultaneously, Cialis 5mg Once-A-Day serves as a unified pharmacological solution. This singular therapeutic pathway simplifies medication compliance and minimizes the risks of polypharmacy (taking multiple medications simultaneously).
Ingredients & Mechanism of Action
Active Constituent
Tadalafil (5mg): A selective and reversible inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5).
Mechanism of Action
During sexual stimulation, local nitric oxide release occurs. This compound activates guanylate cyclase, increasing cellular cGMP levels.
In the Corpus Cavernosum: Tadalafil selectively inhibits the PDE5 enzyme, preventing the degradation of cGMP. This preserves smooth muscle relaxation, increases arterial blood inflow, and facilitates an erection.
In the Prostate and Bladder: The inhibition of PDE5 increases cGMP concentration in the smooth muscles of the lower urinary tract, inducing muscle relaxation and reducing neuromuscular tension in the bladder neck and prostate.
Usage Instructions & Safety Precautions
Clinical Administration Guidelines
Dosing Schedule: Ingest one (1) tablet daily at approximately the same time of day, independent of food intake.
Method of Administration: Swallow the film-coated tablet whole with water. Do not crush, split, or chew the tablet, as this can alter the sustained-release properties.
Missed Dose: If a daily dose is missed, it should be taken as soon as noticed. However, patients must never double the dose to compensate for a missed tablet.
Contraindications and Drug Interactions
Critical Medical Warning: Cialis must never be administered alongside any form of organic nitrates (such as nitroglycerin, isosorbide mononitrate, or amyl nitrite) used for angina or cardiac conditions. Co-administration can trigger acute, life-threatening hypotension (severe drop in blood pressure).
Guanylate Cyclase Stimulators: Do not use in combination with medications like Riociguat.
Cardiovascular Risk: Daily use is contraindicated in patients with severe hepatic impairment, recent myocardial infarction (heart attack) within the last 90 days, unstable angina, or severe uncontrolled arrhythmias.
Alpha-Blockers: Caution and dosage adjustments are required when co-administering with alpha-blockers used for hypertension or BPH, as both classes of drugs act as vasodilators and can lower blood pressure.
Storage Parameters
Store in the original blister packaging at a temperature below 30°C. Keep protected from moisture and direct sunlight. Store strictly out of reach of children.
