What it is and what it is used for

for

The active substance of Solifenacin succinate oral suspension belongs to the group of anticholinergics. These medicines are used to reduce the activity of an overactive bladder. This enables you to wait longer before having to go to the bathroom and increases the amount of urine that can be held by your bladder. Solifenacin succinate oral suspension is used to: –

treat the symptoms of a condition called overactive bladder in adults. These symptoms include: having a strong, sudden urge to urinate without prior warning, having to urinate frequently or wetting yourself because you could not get to the bathroom in time.

–

treat a condition called neurogenic detrusor overactivity in children aged 2 to 18 years. Neurogenic detrusor overactivity is a condition in which involuntary bladder contractions occur due to a condition that you are born with or injury to the nerves which control the bladder. If left untreated, neurogenic detrusor overactivity may lead to damage to your bladder and/or kidneys. Solifenacin succinate oral suspension is used to increase the amount of urine your bladder can hold and reduce urine leakage.

4.4. Special warnings and precautions for use

Other causes of frequent urination (heart failure or renal disease) should be assessed before treatment with solifenacin. If urinary tract infection is present, an appropriate antibacterial therapy should be started.

Solifenacin should be used with caution in patients with:

- clinically significant bladder outflow obstruction in the absence of clean intermittent catheterization because of the risk of urinary retention.

- gastrointestinal obstructive disorders.

- risk of decreased gastrointestinal motility.

- severe renal impairment (creatinine clearance ≤ 30 ml/min), and doses should not exceed 5 mg (5 ml) in adults or the starting dose in children and adolescents for these patients (see Section 4.2 and 5.2).

- moderate hepatic impairment (Child-Pugh score of 7 to 9), and doses should not exceed 5 mg (5 ml) in adults or the starting dose in children and adolescents for these patients (see Section 4.2 and 5.2).

- concomitant use of a potent CYP3A4 inhibitor, e.g. ketoconazole, and doses should not exceed 5 mg (5 ml) in adults or the starting dose in children and adolescents for these patients (see Section 4.2 and 4.5).

- hiatus hernia/gastro-oesophageal reflux and/or who are concurrently taking medicinal products (such as bisphosphonates) that can cause or exacerbate oesophagitis.

- autonomic neuropathy.

QT prolongation and Torsade de Pointes have been observed in patients with risk factors, such as pre-existing long QT syndrome and hypokalaemia.

Angioedema with airway obstruction has been reported in some patients on solifenacin. If angioedema occurs, solifenacin should be discontinued and appropriate therapy and/or measures should be taken.

Anaphylactic reaction has been reported in some patients treated with solifenacin. In patients who develop anaphylactic reactions, solifenacin should be discontinued and appropriate therapy and/or measures should be taken.

The maximum effect of solifenacin can be determined after 4 weeks at the earliest.

This medicine contains 20 mg propylene glycol in each ml which is equivalent to 200 mg/10 ml.

This medicine contains 100 mg xylitol in each ml which is equivalent to 1000 mg/10 ml. Xylitol may have a laxative effect. Calorific value 2.4 kcal/g xylitol.

This medicine contains 0.0002 mg benzyl alcohol in each ml which is equivalent to 0.002 mg/10 ml. Benzyl alcohol may cause allergic reactions.

This medicine contains less than 1 mmol sodium (23 mg) per ml, that is to say essentially 'sodium-free'.

4.5. Interaction with other medicinal products and other forms of interaction

Pharmacological interactions

Concomitant medication with other medicinal products with anticholinergic properties may result in more pronounced therapeutic effects and undesirable effects. An interval of approximately one week should be allowed after stopping treatment with solifenacin, before commencing other anticholinergic therapy. The therapeutic effect of solifenacin may be reduced by concomitant administration of cholinergic receptor agonists.

Solifenacin can reduce the effect of medicinal products that stimulate the motility of the gastro-intestinal tract, such as metoclopramide and cisapride.

Pharmacokinetic interactions

In vitro studies have demonstrated that at therapeutic concentrations, solifenacin does not inhibit CYP1A1/2, 2C9, 2C19, 2D6, or 3A4 derived from human liver microsomes. Therefore, solifenacin is unlikely to alter the clearance of drugs metabolised by these CYP enzymes.

Effect of other medicinal products on the pharmacokinetics of solifenacin

Solifenacin is metabolised by CYP3A4. Simultaneous administration of ketoconazole (200 mg/day), a potent CYP3A4 inhibitor, resulted in a two-fold increase of the AUC of solifenacin, while ketoconazole at a dose of 400 mg/day resulted in a three-fold increase of the AUC of solifenacin. Therefore, the maximum dose of solifenacin should be restricted to 5 mg (5 ml) for adults or the starting dose for children and adolescents, when used simultaneously with ketoconazole or therapeutic doses of other potent CYP3A4 inhibitors (e.g. ritonavir, nelfinavir, itraconazole) (see Section 4.2).

Simultaneous treatment of solifenacin and a potent CYP3A4 inhibitor is contra-indicated in patients with severe renal impairment or moderate hepatic impairment.

The effects of enzyme induction on the pharmacokinetics of solifenacin and its metabolites have not been studied as well as the effect of higher affinity CYP3A4 substrates on solifenacin exposure. Since solifenacin is metabolised by CYP3A4, pharmacokinetic interactions are possible with other CYP3A4 substrates with higher affinity (e.g. verapamil, diltiazem) and CYP3A4 inducers (e.g. rifampicin, phenytoin, carbamazepin).

Effect of solifenacin on the pharmacokinetics of other medicinal products

Oral Contraceptives

Intake of solifenacin showed no pharmacokinetic interaction of solifenacin on combined oral contraceptives (ethinylestradiol/levonorgestrel).

Warfarin

Intake of solifenacin did not alter the pharmacokinetics of R-warfarin or S-warfarin or their effect on prothrombin time.

Digoxin

Intake of solifenacin showed no effect on the pharmacokinetics of digoxin.

4.6. Fertility, pregnancy and lactation

Pregnancy

No clinical data are available from women who became pregnant while taking solifenacin. Animal studies do not indicate direct harmful effects on fertility, embryonal / foetal development or parturition (see Section 5.3). The potential risk for humans is unknown. Caution should be exercised when prescribing to pregnant women.

Breast-feeding

No data on the excretion of solifenacin in human milk are available. In mice, solifenacin and/or its metabolites was excreted in milk, and caused a dose dependent failure to thrive in neonatal mice (see Section 5.3). The use of solifenacin should therefore be avoided during breast-feeding.

Fertility

There are no clinical data available on effects of solifenacin on fertility. No effects on fertility were observed in animals.

4.7. Effects on ability to drive and use machines

Since solifenacin, like other anticholinergics may cause blurred vision, and, uncommonly, somnolence and fatigue (see Section 4.8. Undesirable effects), the ability to drive and use machines may be negatively affected.

4.8. Undesirable effects

Summary of the safety profile

Due to the pharmacological effect of solifenacin, solifenacin may cause anticholinergic undesirable effects of (in general) mild or moderate severity. The frequency of anticholinergic undesirable effects is dose related.

The most commonly reported adverse reaction with solifenacin was dry mouth. It occurred in 11% of patients treated with 5 mg once daily, in 22% of patients treated with 10 mg once daily and in 4% of placebo-treated patients. The severity of dry mouth was generally mild and did only occasionally lead to discontinuation of treatment. In general, medicinal product compliance was very high (approximately 99%) and approximately 90% of the patients treated with solifenacin completed the full study period of 12 weeks treatment.

Paediatric population

Solifenacin oral suspension has been evaluated for safety in 95 paediatric patients aged 2 years to less than 18 years with neurogenic detrusor overactivity in two open-label trials. Common adverse reactions observed in the paediatric population with NDO include: constipation, dry mouth, abdominal pain, somnolence, urinary tract infection, bacterial test positive, and QT prolonged. The incidence of constipation in patients treated with solifenacin oral suspension was higher in the maximum dose group compared to the starting dose group.

In the paediatric patients with NDO, no severe adverse reactions were reported. The most frequent adverse reaction leading to study discontinuation was QT prolongation.

Overall, the safety profile in children and adolescents is similar to that observed in adults.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.co.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9. Overdose

Symptoms

Overdosage with solifenacin can potentially result in severe anticholinergic effects. The highest dose of solifenacin accidentally given to a single patient was 280 mg in a 5-hour period, resulting in mental status changes not requiring hospitalization.

Treatment

In the event of overdose with solifenacin the patient should be treated with activated charcoal. Gastric lavage is useful if performed within 1 hour, but vomiting should not be induced.

As for other anticholinergics, symptoms can be treated as follows:

- Severe central anticholinergic effects such as hallucinations or pronounced excitation: treat with physostigmine or carbachol.

- Convulsions or pronounced excitation: treat with benzodiazepines.

- Respiratory insufficiency: treat with artificial respiration.

- Tachycardia: treat with beta-blockers.
