Trospium Pharmacology

On this episode, I discuss trospium pharmacology, adverse effects, and important drug interactions you should know. Trospium chloride (Sanctura) is a bladder antimuscarinic or anticholinergic. It blocks the action of acetylcholine in bladder smooth muscle. It is used for urinary frequency and overactive bladder. The immediate-release formulation is taken twice a day. There is an extended-release version that is more expensive. As its classification suggests it is going to have anticholinergic effects that include dry eyes, dry mouth, constipation, urinary retention, GI tract slowing down, CNS sedation, and increased risk of falls. Compared to older bladder anticholinergics such as oxybutynin or tolterodine there is less CNS penetration. Hopefully, this will cause the patient to experience fewer CNS side effects. A downside to this being a newer medication is that it costs more. Trospium is on the BEERS list. Look for medications started after the trospium that indicate anticholinergic side effects such as saliva substitutes, an increase in BPH medications, artificial tears, or constipation medications. It should be administered on an empty stomach as food can block absorption. If the patient is currently taking it with food and seeing results there is no need to change how they are taking it. Trospium is not metabolized by CYP enzymes minimizing drug interactions. Most interactions occur because of additive effects. Avoid using it with other medications on the BEERS list, especially other anticholinergic medications. Be cautious using other medications with sedative effects and CNS depression (benzodiazepines, sleep medications, opioids, alcohol) as they may have additive effects.

Pharmacology is one of the most challenge topics you will encounter as a healthcare professional, but it can be the most rewarding with a good understanding. Whether you are preparing to be a nurse, physician, physician assistant, pharmacist, dentist, nurse practitioner, pharmacy technician, pharmacologist, or other healthcare professional, this podcast will help you better understand pharmacology. In addition to giving you the basics like mechanism of action, side effects, drug interactions, etc., you will also be exposed to how medications actually impact patients in real life. In the Real Life Pharmacology podcast, Eric Christianson, PharmD shares his real world experiences about how a medication's mechanism of action, pharmacokinetics, adverse effects, and drug interactions can actually impact patients in both a positive and a potentially negative way. Eric Christianson PharmD is the author of the popular clinical pharmacy blog Meded101.com. People who are passionate about nursing, medicine, or pharmacy will find this podcast beneficial in helping them prepare for passing exams. This podcast is for educational purposes only and is not medical advice or intended to be a substitute for medical advice. Please seek advice from your pharmacist or primary care provider if you have questions about medications that you are taking.
