The primary symptoms of menopause are genitourinary
and vasomotor. The genitourinary syndrome
of menopause (GSM) includes symptoms such as
burning, irritation, dryness, dyspareunia, dysuria,
and recurrent urinary tract infection. Vasomotor
symptoms (VMS; hot flashes, night sweats) often
disrupt sleep.

A nephrologist and longtime reader of The Medical Letter
wrote us to say that our recent article entitled Drugs for
Anxiety Disorders should have said more about the need
for dosage adjustment of gabapentin (Neurontin, and
others) and pregabalin (Lyrica, and others) in patients
with renal impairment. Both drugs, he pointed out, are
exclusively renally eliminated and can accumulate in
patients with diminished renal function. Symptoms,
which can include altered mental status, may develop
so slowly that neither the patient nor the practitioner
connect them to the drug. The resolution of adverse
effects upon discontinuation can be slow.

Fezolinetant (Veozah – Astellas), a first-in-class
neurokinin 3 (NK3) receptor antagonist, has been
approved by the FDA for treatment of moderate to
severe vasomotor symptoms (VMS) due to menopause.
It is the second nonhormonal treatment to be approved
in the US for this indication; a low-dose formulation of
the selective serotonin reuptake inhibitor (SSRI)
paroxetine mesylate (Brisdelle) was approved in 2013.

Cognitive behavioral therapy for insomnia (CBT-I) is
recommended for initial treatment of chronic insomnia.
CBT-I includes stimulus control, sleep education
and hygiene, sleep restriction, relaxation training, and
cognitive therapy. When CBT-I alone is not effective,
pharmacologic treatment should be added.
Nonopioid Drugs for Pain

Nonopioid drugs can be used in the treatment of
many nociceptive and neuropathic pain conditions.
For severe pain, especially severe chronic cancer
pain, use of opioids may be necessary. Noninvasive
nonpharmacologic treatments, including physical
and psychological therapies, have been shown to
improve pain and function in patients with some
common chronic pain conditions and are unlikely
to cause serious harms. A multimodal approach to
analgesic therapy can increase pain control while
reducing opioid use and adverse effects.

Consumption of alcohol has increased during the
COVID-19 pandemic. The Diagnostic and Statistical
Manual for Mental Disorders, 5th edition (DSM-5) defines
alcohol use disorder (AUD; previously called alcohol
dependence) as meeting ≥2 of the 11 criteria listed in
Table 1 in the past year. The lifetime prevalence of AUD
in the US population has been estimated to be about
30%. Despite this high prevalence and the associated
morbidity, mortality, and costs, only 3 drugs are FDA-approved
for treatment of the disorder.

The primary symptoms of menopause are genitourinary
(genitourinary syndrome of menopause; GSM) and
vasomotor (VMS). Vulvovaginal atrophy can cause
vaginal burning, irritation and dryness, dyspareunia, and
dysuria, and increase the risk of urinary tract infections.
Vasomotor symptoms ("hot flashes") cause daytime
discomfort and night sweats that may disrupt sleep.
Hormone therapy is the most effective treatment for both
genitourinary and vasomotor symptoms.

Anxiety disorders (generalized anxiety disorder, panic
disorder, social anxiety disorder, and various phobias)
are the most common form of psychiatric illness. They
can be treated effectively with cognitive behavioral
therapy (CBT) and/or pharmacotherapy. Obsessive-compulsive
disorder and posttraumatic stress
disorder are now considered separate entities in the
Diagnostic and Statistical Manual of Mental Disorders
(DSM-5); they can also be treated with CBT and many
of the same drugs.

Treatment of epilepsy should begin with a single
antiepileptic drug (AED), increasing its dosage
gradually until seizures are controlled or adverse
effects become intolerable. If seizures persist,
specialists generally recommend trying at least
one and sometimes a second alternative drug as
monotherapy before considering use of two drugs
concurrently. When used for the appropriate seizure
type, AEDs are roughly equivalent in efficacy. Drug
choice is usually based on factors such as ease of
use, adverse effects, drug interactions, presence of
comorbidities, and cost.

Pain can be acute or chronic. The two major types of
chronic pain are nociceptive pain and neuropathic
pain. Nociceptive pain can be treated with nonopioid
analgesics or opioids. Neuropathic pain is less responsive
to opioids and is often treated with adjuvant drugs
such as antidepressants and antiepileptics. Combining
different types of analgesics may provide an additive
analgesic effect without increasing adverse effects.

Treatment of epilepsy should begin with a single
drug, increasing the dosage gradually until seizures
are controlled or adverse effects become unacceptable.
If seizures persist, expert clinicians generally
prescribe at least one and sometimes a second alternative
drug as monotherapy before considering use of
two drugs at the same time. When used for the appropriate
seizure type, antiepileptic drugs are roughly
equivalent in efficacy. The choice of drug is usually
based on factors such as ease of use, adverse effects,
interactions with other drugs, presence of comorbid

Lamotrigine was first marketed abroad in 1990 and is now available in more than 50 other countries.
