MPTP is used to model Parkinson’s disease. It turns into MPP+ and leads to the death of dopaminergic neurons. How was this figured out?

MPPP was an opioid synthesized in 1947. Due to difficulty acquiring heroin at the time, Barry Kidston read the MPPP paper in 1976 and tried to synthesize it, but it had MPTP impurity 😱

He presented with Parkinsonian symptoms, was treated, but died of an overdose. Autopsy revealed loss of SN DA neurons. NIMH found MPTP in his lab.

Happy #PharmPhriday!

The #FDA just approved Veozah (fezolinetant) for the treatment of moderate to severe hot flashes caused by #menopause.

The drug is a neurokinin 3 (NK3) receptor antagonist, the first to be approved by the FDA for hot flashes. The NK3 receptor plays a role in regulating body temperature.

ACE-inhibitors are a type of drug used to treat #hypertension. They prevent angiotensin converting enzyme (ACE) from turning angiotensin I to II, BUT they can trigger the cough reflex!

If you’re having chronic cough issues with an ACE-inhibitor (drug name usually ending in -il), talk to your doctor about other options šŸ«€

Good morning, and happy #PharmPhriday!

I regularly revisit this piece on #tetanus in an unvaccinated child. It is short, fascinating, heartbreaking, and incredibly frustrating story: cdc.gov/mmwr/volumes/68/wr/mm6

Happy #PharmPhriday! A question I get a lot is ā€œwhat’s a #biosimilar?ā€ Well, it’s like a #generic but for #biologics

Because a biologic is made from something living, you can’t exactly copy the drug recipe like you can with generics. There are also some differences in testing.

A biosimilar has no clinically meaningful differences from an existing FDA-approved biologic.

A generic drug demonstrates bioequivalence to an existing FDA-approved drug.

Infographic from fda.gov/media/166334/download

Biosimilars
Generally made from living sources
Require a specialized process to produce
Very similar, but not identical, to original biologics
Faster development process using public information from original biologic approval
Usually less expensive than original biologics

Generics
Generally made from chemicals
Have a simpler process to copy
Copy of brand-name drugs
Usual as expensive than

#Hormones can be confusing, so let’s break down some of their functions, starting with progesterone. One important role is maintaining a pregnancy (hence why #mifepristone, a progesterone blocker, is an #abortion drug).

#Progesterone can be administered intramuscularly (in oil, PIO) or vaginally; oral has been shown to be less effective.

If you don’t want a daily šŸ’‰šŸ‘ through 1st trimester, talk to your doc about vaginal progesterone! #OBGynodon #Fertility #Infertility #IVF

Happy #PharmPhriday! With the 🄶 season still hitting, you might be prescribed benzonatate (Tessalon) pearls. This drug works on vagal afferent fibers and stretch receptors to reduce the cough reflex.

Accidental ingestion by children under 10, even 1-2 capsules, can lead to overdose and death. Overdose symptoms can have a rapid onset, within 15-20min of ingestion.

I keep track of how many I’ve taken by using a tally on the bottle to know if any are missing.

It’s #PharmPhriday! We have personally been affected by the injectable #lidocaine #shortage, so today will be about lidocaine! Some cells signal via action potential. When there’s sufficient stimulus, sodium enters the cell, potassium (also positively charged) exits, then the cell membrane returns to baseline ā€œresting potentialā€.

Sodium enters through a sodium channel, and what does lidocaine do? Block sodium channels! No sodium entry, no action potential, no pain signal.

Image from https://www.moleculardevices.com/applications/patch-clamp-electrophysiology/what-action-potential 

Stimulus starts the rapid change in voltage or action potential. In patch-clamp mode, sufficient current must be administered to the cell in order to raise the voltage above the threshold voltage to start membrane depolarization.
Depolarization is caused by a rapid rise in membrane potential opening of sodium channels in the cellular membrane, resulting in a large influx of sodium ions.
Membrane Repolarization results from rapid sodium channel inactivation as well as a large efflux of potassium ions resulting from activated potassium channels.
Hyperpolarization is a lowered membrane potential caused by the efflux of potassium ions and closing of the potassium channels.
Resting state is when membrane potential returns to the resting voltage that occurred before the stimulus occurred.

Happy #PharmPhriday! We joke about the ā€œDrā€ in ā€œDr Pepperā€, but did you know it was created by #pharmacist Charles Alderton in the 1880s? Dr. Pepper (period dropped in the 1950s) advertised as being able to aid digestion and restore vim, vigor, and vitality ✨

While searching #vintage ads, I saw a few saying to drink it at 10, 2, and 4, and even old bottles with the numbers on the logo. This is from an old slogan contest, after showing those times of day are associated with dips in energy.

A vintage ad for Dr Pepper showing a couple each holding a bottle of soda. The ad says Drink Dr. Pepper Good For Life! 5 cents. The bottom says at 10-2 and 4 o’clock.

It’s #PharmPhriday! Due to the #Speaker fiasco in the #House, I’ll share some #etymology.

Did you know both candidiasis (yeast infection) and candidate stem from the Latin candidus meaning ā€˜shining white’?

In ancient #Rome, political candidates would wear super white togas while campaigning and were known as candidati or ā€˜whitened men’, presumably to signify their pure intentions.

🧠 #Benzodiazepines are positive allosteric modulators and require a γ subunit and the presence of GABA to work! Their effects are mediated by the α subunit.

ā— Anxiolytics - α2, α3
ā— Sedatives - α1, α5
ā— Anticonvulsants - α1, α2, α3, α5
ā— Anterograde amnesia - α1

α4 and α6 do not bind benzodiazepines
ā— Possess arginine where other α subunits have histidine

It’s #PharmPhriday time! With the #holidays being a tough time for many who struggle with #MentalHealth, I thought I’d share a bit of GABAA receptor #pharmacology.

🧠 Pentameric receptor for inhibitory neurotransmitter, GABA
🧠 2 α, 2 β, 1 other subunit
🧠 Activation hyperpolarizes cell
due to chloride entry
🧠 Subunits determine
pharmacological sensitivity and physiological properties
