Dexmedetomidine is a selective alpha-2-adrenergic agonist with sedative characteristics.

Dexmedetomidine is commonly used in ICU and procedural sedation, as well as postoperative pain.

A few of the more serious adverse effects of dexmedetomidine to keep an eye on including bradyarrhythmias/bradycardia and hypotension.

Dexmedetomidine undergoes hepatic metabolism, meaning a dose reduction may be required in patients with impaired hepatic function.

Major drug interactions to monitoring for with dexmedetomidine include co-administration with anesthetics, sedatives, hypnotics, and opioids, as it may lead to an enhancement of effects.

I discuss important drug interactions on the podcast, be sure to check out my latest project which is a 200+ page book on managing drug interactions in primary care.

It is also important to note that dexmedetomidine may produce withdrawal symptoms if used for longer than 24 hours.

On this episode, I discuss the pharmacology of calcitonin.

Calcitonin has an indication for osteoporosis as well as hypercalcemia.

When considering drug interactions with calcitonin, recall that it can lower calcium levels which could have a cumulative effect when combined with loop diuretics.

Calcitonin nasal spray should be stored upright and primed prior to use.

Rivastigmine is an acetylcholinesterase inhibitor used in the management of certain dementias. I discuss rivastigmine pharmacology on this episode.

Weight loss is a potential adverse effect of rivastigmine. It is important to monitor weights.

Anticholinergic medications such as diphenhydramine can blunt the effects of rivastigmine.

Rarely, acetylcholinesterase inhibitors like rivastigmine can cause bradycardia.

Caffeine is a commonly used supplement and is found in many food and beverages. I discuss caffeine pharmacology, adverse effects, and drug interactions.

Caffeine can inhibit CYP1A2 and also be affected by CYP1A2 inhibitors. I discuss some examples in the podcast.

It is critical to inquire about caffeine intake when patients are reporting insomnia.

Caffeine has been associated with increases in pulse and blood pressure. Be sure to ask about caffeine intake when assessing these vital signs.

Colestipol is a bile acid sequestrant that can be used in the management of hyperlipidemia.

By binding bile acid in the gut, colestipol can lower LDL that is bound to bile acid by eliminating it through the feces.

Numerous drug interactions existed as colestipol can bind many drugs. This is a downside to its use and why it isn’t a preferred hyperlipidemia agent.

In patients with elevated triglycerides, colestipol should be avoided.
