I just completed a modification of my Medication Checklist
that I have been using for the past 20 years.
The intent of the checklist was provided and easy way for patients I was
seeing to recall any medications that had been treated with in the past. There
was not attempt to classify the medications in a more precise manner. I found it was successful for its intended
purpose and allowed for a discussion of other potentially useful medications as
well as the limitations of this kind of classification. As an example, there are overlap categories
between antipsychotic medications and mood stabilizers as well as anxiolytics
and antidepressants.
My last update was 5 years ago. Since then, there have been 24 additions, but
very few in terms of new medications.
Most of the changes have all been changes in drug formulations
(sustained release, combination medications, a new transdermal patch, and
longer acting injectable medications. I
included one GLP-1A agonist – tirzepatide (Zepbound, Mounjaro) because it has a
new indication for obstructive sleep apnea and sleep medicine is a
growing subspeciality in psychiatry.
I included a new category of Agitation, because
dexmedetomidine has that indication. The
only other medications typically in that class are antipsychotics and mood
stabilizers but it is far from inclusive.
In acute care psychiatry, most of the medication used to treat this
problem are not FDA approved but are from the same classes as the approved
drugs. The only exception are
benzodiazepine drugs that are often combined with antipsychotics.
The time domain for this list is about 40 years. That means
there are several older medications on the list that are no longer manufactured
or prescribed. It is useful to retain them because many people coming in for
new assessments may have been exposed to them over the years.
Gepirone is an interesting addition. I posted
previously about how azapirones (buspirone and gepirone) seemed to be
neglected compounds in psychiatry. Despite buspirone having an anxiety disorder
only indication, gepirone was approved for depression in 2023. The current
package insert says it is indicated for depression only. It is a once-a-day dosing but it has a QTc
prolongation warning and may require more intensive medical monitoring for that
reason.
Viloxazine is a selective norepinephrine reuptake inhibitor
(SNRI) that is structurally dissimilar to atomoxetine – an earlier SNRI used to
treat Attention Deficit-Hyperactivity Disorder.
The most significant new medication is likely to be
Xanomeline trospium chloride (Cobenfy).
It is a new antipsychotic medication with a novel mechanism of action. Xanomeline
is a CNS M1 and M4 muscarinic acetylcholine receptors agonist. Trospium is a muscarinic acetylcholine
receptor antagonist primarily in the peripheral tissues making it a first in
class medication.
The medication sheet contains several medications that are
used to treat symptoms and medication wide effects. There is a total of 142 medications (not
counting various reformulations of the same compound).
I am currently working on reclassifying the medication on
this sheet by two different systems – the Anatomical Therapeutic Chemical
(ATC) classification system based on more formal indications and the Neuroscience-based
Nomenclature (NbN) based on purported mechanisms of action. At some point I will also try to put them all
on a timeline based on when they were FDA approved.
In the meantime, the list can be accessed and printed
out. It is setup to fit on both sides of
a standard piece of paper. During an
interview if a person has a difficult time recalling medications – I will show
them the list and point out the section that is most likely relevant. I never include it in the medical record, but
use it as part of my notes to record the clinical encounter or check pharmacy
records.
Let me know what you think and if I missed anything.
