Solifenacin succinate Usage And Synthesis
DescriptionSolifenacin succinate is an antimuscarinic medication that is used to treat an overactive bladder causing symptoms of frequency, urgency, or incontinence.
Proper Usage
  1. This medication should be taken with liquids and swallowed whole. It may be taken with or without food.
  2. Take only the amount of this medication that has been prescribed for you by your doctor; taking more than the prescribed amount can cause adverse effects.
  3. If you miss a dose of this medication, begin taking it again the next day. Do not take two doses of solifenacin succinate in the same day.
Precautions
  1. Individuals with any of the following medical problems should not take this medication: urinary retention, gastric retention, narrow angle or uncontrolled glaucoma, or severe kidney problems. Solifenacin succinate can aggravate each of these conditions.
  2. Solifenacin succinate may cause blurred vision; do not engage in potentially dangerous activities such as driving until you know the effect of the medication on your vision.
  3. This medication, like all anticholinergic medications, may cause drying of the mouth. Since continued dryness of the mouth can increase the risk of dental disease, alert your dentist if you are taking this medication.
  4. Like all anticholinergic medications, solifenacin succinate can cause or worsen constipation.
  5. Because of decreased sweating, this medication can cause heat prostration when used in a very hot environment.
  6. This medication has not been studied in pregnant women. However, it has been shown in animal studies to impact preand postnatal development. If you are pregnant, or planning to become pregnant, do not start this medication before you have discussed it with your physician.
  7. It is not known whether solifenacin succinate passes into breast milk. Women who taking this medication and wish to breastfeed should discuss it with their physician.
Possible Side effects
  1. Side effects that are expected with this type of medication and do not require medical attention unless they continue or are bothersome: dry mouth; dry eyes; constipation, blurred vision, difficult urination.
  2. Less common side effect that should be reported to your physician: severe abdominal pain.
  3. Symptoms of overdose: severe central anticholinergic effects, including blurred vision; clumsiness or unsteadiness; confusion; seizures; severe diarrhea; excessive watering of the mouth; increasing 240 Multiple Sclerosis: A Self-Care Guide to Wellness muscle weakness (especially in the arms, neck, shoulders, and tongue); muscle cramps or twitching; severe nausea or vomiting; shortness of breath; slow heartbeat; slurred speech; unusual irritability, nervousness, or restlessness; unusual tiredness or weakness.
DescriptionSolifenacin is an M3 muscarinic receptor antagonist that was developed and launched for the treatment of overactive bladder (pollakiuria) in Europe. M3 receptors have been implicated in neurally evoked smooth muscle contractions of the bladder, and M2 receptors have also been suspected of playing a role because of their dominance in the detrusor muscle. Solifenacin displays affinity for both M3 and M2 receptors with Ki values of 9.9nM and 120 nM, respectively. Since muscarinic salivary glands are of the M3 persuasion, a common side effect of antimuscarinic therapy is dry mouth. At the cellular level, solifenacin possesses a selective preference for bladder over salivary gland that is 15-fold greater than that of atropine suggesting a lower probability of inducing dry mouth at pharmacologically relevant doses. The synthesis of solifenacin involves the preparation of racemic 1-phenyl- 1,2,3,4-tetrahydroisoquinoline via cyclization of N-(2-phenylethyl)benzamide, and subsequent reaction with ethyl chloroformate and transesterification with (R)- 3-quinuclidinol. Chiral chromatography affords the isolation of the desired diastereomer. Alternatively, 1-phenyl-1,2,3,4-tetrahydroisoquinoline may be subjected to optical resolution with (+)-tartaric acid prior to treatment with ethyl chloroformate and subsequent transesterification. The pooled results of four phase III trials concluded that 63% of women receiving 5mg of solifenacin once daily and 68% of women receiving 10mg once daily reported a 50% or more reduction in urgency episodes, compared to 44% of women taking placebo. This compares with a 53% reduction in patients receiving tolterodine twice daily. In another placebo-controlled trial, with the change in the number of micturitions in a 24-h period as the primary endpoint, once-daily solifenacin recorded an 18% decrease for a 5-mg dose and a 21% decrease for a 10-mg dose compared to 10% with placebo. Pharmacokinetic studies have demonstrated that solifenacin has an oral bioavailability of 90%, a long elimination half-life (50 h), low clearance (9.39 L/h), a mean Vss of 599 L, a Cmax of approximately 14 ng/mL, and a time to maximal plasma concentration of 4 h making it suitable for q.d. dosing. Furthermore, these PK parameters are not affected by food ingestion. Solifenacin is excreted predominantly in the feces with only 3–6% found in urine. It is contraindicated in patients with hepatic impairment, gastric retention, urinary retention, or uncontrolled narrow angle glaucoma. Further precautions, such as dose adjustment, should be considered for patients with concurrent use of ketoconazole or other potent CYP3A4 inhibitors or for patients with a history of QT prolongation or currently on medications known to prolong the QT interval. Finally, while other muscarinic antagonists have been explored in the treatment of irritable bowel syndrome (IBS), it is too early to predict the therapeutic utility of solifenacin for IBS although animal studies are promising.

DefinitionChEBI: Solifenacin succinate is a member of isoquinolines.
Brand nameVesicare (Astellas).
General DescriptionSolifenacin succinate (Vesicare),(+)-(1S, 3'R)-quinuclidin-3'-yl 1-phenyl-1,2,3,4-tetrahydroisoquinoline-2-carboxylate, is a competative antagonistfor M1, M2, and M3 receptor subtypes. One of the issues surroundingthe use of such antagonists is the selectivity for thebladder over other tissue such as the salivary glands. It isreported that the selectivity of solifenacin for bladder muscarinicreceptors over salivary receptors is superior to theeffects observed with oxybutynin.
Clinical UseSelective M3 antimuscarinic
Symptomatic treatment of urge incontinence and/or increased urinary frequency and urgency
in vitroin radioligand receptor binding assay, the kivalues of solifenacin for human muscarinic m1, m2, m3, m4and m5receptors were 26, 170, 12, 110 and 31 nm, respectively. in isolated rat urinary bladder, solifenacin competitively antagonized carbachol-induced contractions, with a pa2value of 7.44±0.09[3].in bladder smooth muscle cells and salivary gland cells isolated from rats, solifenacin and the other antimuscarinic drugs inhibited carbachol-induced increases in intracellular ca2+levels in a concentration-dependent manner. thepki was 8.12for bladder smooth muscle cells, 3.6-fold more potent than that for salivary gland cells (pki=7.57) [1].
in vivoin anesthetized rats, solifenacin dose-dependently inhibited carbachol-induced intravesical pressure elevation and salivary secretion, and exhibited selectivity (3.7- to 6.5-fold) for urinary bladder over salivary gland [1]. in anesthetized rats, solifenacin and oxybutynin increased the maximum bladder capacity in a dose-dependent manner and also decreased the maximum intravesical pressure [3].in healthy young men, multidose study evaluated doses. in the single-dose of solifenacin succinate (5-, 10-, 20-, and 30-mg), mean time to maximal concentration and elimination half-life ranged from 3.3 to 4.8 and from 40.2 to 57.6 hours, respectively.in the multidose study, the ranges were 2.9 to 5.8 and 45.0 to 64.8, respectively. the single-dose administration was well tolerated. the common adverse events were dry mouth, blurred vision, and headache [4].
Drug interactionsPotentially hazardous interactions with other drugs
Avoid if GFR<30 mL/min if also taking itraconazole, ketoconazole or ritonavir.
Anti-arrhythmics: increased risk of antimuscarinic side effects with disopyramide.

MetabolismExtensively metabolised in the liver, mainly by the cytochrome P450 isoenzyme CYP3A4 and is excreted mainly as metabolites in urine and faeces.
