Flotros (Trospium chloride)
What is it used for? Increased need to pass…
What is it used for?
- Increased need to pass urine (urinary frequency), uncontrollable urges to pass urine (urinary urgency) and involuntary leakage of urine (urinary incontinence)due to an overactive bladder.
How does it work?
- Flotros (Trospium chloride) tablets contain the active ingredient trospium chloride, which is a type of medicine called an anticholinergic (or antimuscarinic) muscle relaxant. It works by relaxing the involuntary muscle that is found in the wall of the bladder.
- The muscle in the wall of the bladder is called the detrusor muscle. It can sometimes contract in uncontrollable spasms, and this is often referred to as having an overactive bladder. The overactive detrusor muscle can increase in the number of times you need to pass urine, or cause uncontrollable urges to pass urine, or involuntary leakage of urine (urinary incontinence).
- Trospium works by relaxing the detrusor muscle in the wall of the bladder. It does this by blocking receptors called cholinergic (or muscarinic) receptors that are found on the surface of the muscle cells. This prevents a natural body chemical called acetylcholine from acting on these receptors.
- Normally when acetylcholine acts on these receptors, it causes the detrusor muscle to contract and the bladder to empty. By blocking acetylcholine, trospium helps the muscle in the bladder wall to relax. This reduces unstable, involuntary contractions of the bladder, and thereby increases the capacity of the bladder to hold urine. In turn, this reduces the need to pass urine.

How can this medicine affect other medicines?
It is important to tell your doctor or pharmacist what medicines you are already taking, including those bought without a prescription and herbal medicines, before you start treatment with this medicine. Similarly, ask your doctor or pharmacist before taking any new medicines while taking this one, so they can check that the combination is safe.
There may be an increased risk of side effects such as dry mouth, blurred vision, constipation and difficulty passing urine, if this medicine is taken with other medicines that have anticholinergic effects, such as the following:
- anticholinergic medicines for Parkinson's symptoms, eg procyclidine, orphenadrine, trihexiphenidyl (benzhexol)
- antihistamines, eg brompheniramine, chlorphenamine
- antipsychotic medicines, eg haloperidol, chlorpromazine, clozapine
- antispasmodic medicines, eg hyoscine, atropine
- other anticholinergic medicines for urinary incontinence, eg tolterodine, solifenacin, propiverine
- MAOI antidepressants, eg phenelzine, tranylcypromine
- tricyclic antidepressants, eg amitriptyline, clomipramine.
- If you experience a dry mouth as a side effect of this medicine you may find that medicines that are designed to dissolve and be absorbed from under the tongue, eg sublingual glyceryl trinitrate (GTN) tablets, become less effective. This is because the tablets do not dissolve properly in a dry mouth. To resolve this, drink a mouthful of water before taking sublingual tablets.
This medicine may reduce the effects of the following medicines on the gut:
Trospium may enhance the increased heart rate that may be experienced after taking beta-sympathomimetic medicines such as the following:
- certain medicines for asthma, eg salbutamol, terbutaline, salmeterol
- decongestant medicines, eg ephedrine, pseudoephedrine, phenylpropanolamine.
The following medicines may reduce the absorption of trospium from the gut and should therefore not be taken at the same time of day as trospium:
- guar gum
