Solifenacin Information

Introduction

Solifenacin is a prescription medication used primarily to treat symptoms of an overactive bladder (OAB), such as urgency, frequency, and urge incontinence. In the United Kingdom it is prescribed when behavioural therapies and lifestyle modifications have not provided adequate symptom control. The active compound is solifenacin, a selective muscarinic‑type 3 (M3) receptor antagonist. Although the supplied data classifies it under “Diuretics,” authoritative sources – including the Medicines and Healthcare products Regulatory Agency (MHRA) and the European Medicines Agency (EMA) – describe solifenacin as an antimuscarinic agent. It is marketed worldwide under several brand names, the most recognised being Vesicare. The medication is manufactured by several licensed pharmaceutical companies; one of the most widely distributed generic versions is produced by Mylan (now Viatris) and Teva UK.

What is Solifenacin?

Solifenacin is the generic version of Vesicare, containing the same active compound, solifenacin. It belongs to the class of antimuscarinic (anticholinergic) drugs that target bladder smooth‑muscle receptors. The molecule was originally developed by Astellas Pharma and received its first marketing authorisation in the European Union in 2005. Since then, multiple generic manufacturers have obtained approval, making the medication more affordable for patients.

Our online pharmacy provides this generic alternative as a cost‑effective treatment option, offering the same therapeutic benefits as the brand‑name product while reducing the financial burden on the patient.

How Solifenacin Works

Solifenacin selectively blocks M3 muscarinic receptors located on the detrusor muscle of the urinary bladder. Under normal circumstances, acetylcholine released from parasympathetic nerves binds to these receptors, triggering muscle contraction and the urge to void. By competitively inhibiting acetylcholine at the M3 site, solifenacin reduces involuntary detrusor contractions, thereby increasing bladder capacity and decreasing urgency episodes.

Key pharmacokinetic points:

• Onset of action: Clinical improvement is often observed within 2–4 weeks of consistent dosing.
• Half‑life: Approximately 45–68 hours, allowing once‑daily dosing.
• Metabolism: Primarily hepatic via CYP3A4, with minor contribution from CYP2D6.
• Excretion: Predominantly fecal (≈70 %) and renal (≈30 %).

These properties contribute to a steady therapeutic effect throughout the day while minimising peaks that could provoke adverse events.

Conditions Treated with Solifenacin

• Overactive Bladder (OAB) with Urge Incontinence – The most common indication. In the UK, OAB affects an estimated 1.5 million adults, with prevalence increasing with age. Solifenacin reduces the average number of urgency episodes per 24 hours by 30–40 % compared with placebo, according to phase III trials (e.g., the CAPABLe study).

• Neurogenic Detrusor Overactivity (NDO) – Secondary use in patients with spinal cord injury or multiple sclerosis, where bladder storage dysfunction is present. Though not a first‑line therapy, solifenacin may be added when anticholinergic monotherapy is insufficient.

• Mixed Urinary Incontinence – In selected cases where both stress and urge components exist, solifenacin can improve the urge component, complementing pelvic‑floor training.

The drug is not indicated for urinary tract infections, bladder outlet obstruction, or renal impairment without careful dose adjustment.

Who is Solifenacin For?

Solifenacin is most appropriate for adults with OAB whose symptoms persist despite behavioural interventions such as bladder training, fluid management, and pelvic‑floor exercises. Typical candidates include:

• Individuals aged ≥18 years with at least three urgency episodes per day or any episode of urge incontinence.
• Patients with a stable renal or hepatic function (e.g., creatinine clearance ≥30 mL/min, liver enzymes ≤2 × upper limit of normal).
• Those who can tolerate anticholinergic side effects (dry mouth, constipation) or for whom these effects are manageable.

Contra‑indications and cautionary use:

• Known hypersensitivity to solifenacin or any excipients.
• Severe uncontrolled narrow‑angle glaucoma, because anticholinergic agents may increase intra‑ocular pressure.
• Significant urinary retention or post‑void residual volume > 200 mL, as further bladder relaxation could exacerbate retention.
• Pregnant or breastfeeding women – safety data are insufficient, and the drug is classified as Category B3 (UK).

Patients with a history of cardiac arrhythmia, hepatic impairment, or who are taking strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin) may require dose reduction or alternative therapy.

Risks, Side Effects, and Interactions

Common

• Dry mouth – Reported in up to 30 % of users; may be mitigated by frequent sips of water or sugar‑free lozenges.
• Constipation – Occurs in 10–15 % of patients; dietary fibre and adequate hydration are advised.
• Blurred vision – Usually transient; patients with pre‑existing visual disorders should be monitored.
• Urinary retention – Mild increase in post‑void residual volume in a minority of patients.

Rare

• Cognitive impairment – Particularly in older adults; clinicians should assess baseline cognition.
• Skin rash or pruritus – May indicate hypersensitivity; discontinuation is recommended if severe.

Serious

• Acute urinary retention – May require catheterisation; patients should seek urgent medical attention if they are unable to void.
• Severe constipation leading to bowel obstruction – Rare but potentially life‑threatening. Immediate medical evaluation is required.
• Cardiovascular events – Isolated reports of tachycardia and palpitations; monitor patients with known arrhythmias.

Drug–Drug Interactions

• CYP3A4 inhibitors (e.g., itraconazole, erythromycin) increase solifenacin plasma concentrations; a dose reduction to 5 mg daily is advised.
• CYP3A4 inducers (e.g., rifampicin, carbamazepine) may reduce efficacy; monitoring of symptom control is essential.
• Other anticholinergics (e.g., antihistamines, tricyclic antidepressants) can potentiate dry‑mouth and constipation.
• Loop diuretics – No direct pharmacokinetic interaction, but concurrent use may exacerbate dehydration; monitor fluid balance.

Patients should disclose all prescribed, over‑the‑counter, and herbal products before initiating therapy.

Practical Use: Dosing, Missed Dose, Overdose

• Standard starting dose: 5 mg taken once daily with or without food.
• Dose titration: If symptoms are inadequately controlled after 2–4 weeks and tolerability is acceptable, the dose may be increased to 10 mg once daily. The maximum recommended dose is 10 mg.
• Renal or hepatic impairment: For creatinine clearance 30–50 mL/min or moderate hepatic dysfunction, the initial dose should be 5 mg; avoid doses above 5 mg.
• Missed dose: Take the missed tablet as soon as remembered if it is at least 4 hours before the next scheduled dose. If the next dose is due within 4 hours, skip the missed tablet and continue with the regular schedule. Do not double‑dose.
• Overdose: Symptoms may include severe constipation, urinary retention, and tachycardia. Immediate medical attention is required. Supportive care, including gastric lavage and activated charcoal, may be considered if presentation is within one hour of ingestion. No specific antidote exists.
• Alcohol and food: Alcohol may increase dry‑mouth severity but does not affect pharmacokinetics. Food does not significantly alter absorption; tablets can be taken with meals for convenience.
• Special populations: Older adults often experience heightened anticholinergic sensitivity; start at the lowest dose and titrate slowly.

FAQ

• Can solifenacin be taken with other bladder‑training exercises?
  Yes, solifenacin is often prescribed alongside behavioural strategies such as timed voiding and pelvic‑floor muscle training. Combining pharmacotherapy with exercises can improve overall symptom control more than either approach alone.

• What should I do if I experience severe dry mouth while using solifenacin?
  Severe xerostomia can be managed by sipping water frequently, chewing sugar‑free gum, or using saliva substitutes. If the problem persists or interferes with eating, contact a healthcare professional for possible dose adjustment.

• Is there a difference between the UK and EU formulations of solifenacin?
  The active ingredient is identical across regions, but excipients (inactive ingredients) may vary slightly to meet local regulatory specifications. Both formulations meet EMA‑mandated bioequivalence standards, ensuring comparable efficacy and safety.

• How long can I store solifenacin tablets before they expire?
  Unopened tablets retain full potency until the expiry date printed on the blister pack, typically two to three years from the date of manufacture. Store them at 15‑30 °C, away from excess moisture and direct sunlight.

• Can I travel internationally with solifenacin tablets in my hand luggage?
  Yes, provided you carry a copy of the prescription or a pharmacist‑issued letter confirming medical necessity. Check the destination country’s import rules, as some jurisdictions may require additional documentation for anticholinergic agents.

• Does solifenacin interact with over‑the‑counter antihistamines?
  Many antihistamines possess anticholinergic properties, which can compound dry‑mouth and constipation. While a mild interaction is expected, it is generally not contraindicated. Monitor symptoms and discuss any concerns with a pharmacist.

• Why is solifenacin not recommended for patients with narrow‑angle glaucoma?
  Antimuscarinic drugs can increase intra‑ocular pressure by reducing aqueous humour outflow, potentially precipitating an acute glaucoma attack. Patients with this condition should avoid solifenacin or use a safer alternative under specialist guidance.

• What is the rationale behind using a lower starting dose in the elderly?
  Age‑related reductions in renal and hepatic clearance, together with heightened sensitivity to anticholinergic effects, raise the risk of adverse events. Starting at 5 mg allows clinicians to assess tolerability before considering dose escalation.

• Are there any known genetic factors that affect solifenacin metabolism?
  Solifenacin is primarily metabolised by CYP3A4; genetic polymorphisms that reduce CYP3A4 activity can increase drug exposure. Although routine genetic testing is not standard practice, clinicians may adjust the dose in patients known to have poor CYP3A4 function.

• Can solifenacin be taken by patients with mild liver disease?
  Mild hepatic impairment (Child‑Pugh A) does not require dose modification, but clinicians should monitor liver function tests periodically, as the drug is metabolised hepatically.

• Is solifenacin compatible with a low‑sodium diet often recommended for bladder health?
  Yes, dietary sodium restriction does not interfere with solifenacin’s pharmacodynamics. A balanced fluid‑intake plan is more pertinent to symptom management than sodium content.

• What packaging options are available when ordering solifenacin from our pharmacy?
  Solifenacin is supplied in blister packs of 30 tablet units, each clearly labelled with strength and expiry date. For larger quantities, multiple blister packs are packed together in a sealed, tamper‑evident envelope.

Glossary

Antimuscarinic (anticholinergic)

A class of drugs that block muscarinic acetylcholine receptors, reducing involuntary smooth‑muscle contractions such as those of the bladder detrusor muscle.

Post‑void residual (PVR)

The volume of urine remaining in the bladder after voluntary voiding, measured typically by ultrasound. Elevated PVR may indicate urinary retention.

Cytochrome P450 3A4 (CYP3A4)

An enzyme in the liver responsible for metabolising many medications, including solifenacin. Inhibitors or inducers of CYP3A4 can alter drug concentrations.

Narrow‑angle glaucoma

A form of eye disease where the drainage angle of the anterior chamber becomes blocked, leading to rapid rises in intra‑ocular pressure. Anticholinergic drugs may worsen this condition.
