These Jovin pages are educational cabinet notes. They do not prescribe a tablet, sell one, or fill one at a window. Cabinet disclaimer

Cabinet notes · Lyon

Five cabinet notes. One nitrate shelf.

open the label, then the mailbag

Tadalafil 10 mg as needed, sildenafil 100 mg after a light plate, vardenafil 10 mg after a QT pass, finasteride 1 mg for hair, amoxicillin 875 mg as a finished course. Jovin writes those locks from the prescribing information. Nothing is sold.

How a note is filed

Open, dose, mail, file

The order is the same on every page. The labelled milligram comes before price. The nitrate hold, the QT line, or the allergy card comes before a fill conversation. Rosalind Hartley answers the mailbag last, then the page is dated.

Open

The current FDA label first, then a named trial if a number in the text needs one. Marketing copy is not a source.

Dose

One labelled lock per page: 10 mg as needed, 100 mg, 10 mg after QT, 1 mg daily, or 875 mg as a course. The rest of the ladder can be named; the SERP lock stays still.

Mail

Reader letters under the remedy, answered in Rosalind's voice, pointed at the same label. Not a clinic visit.

File

A dated review, a freshness stamp, and a link to the cabinet disclaimer. If the label moves, the page moves.

The journal

Three PDE5 clocks on one spread

The comparison puts tadalafil 10 mg, sildenafil 100 mg and vardenafil 10 mg side by side on onset, food, QT and the shared nitrate hold. Read it before you pick a remedy page by brand colour.

The cabinet

Five remedy pages, each with its own lock

A full write-up per molecule: mechanism, the locked milligram, the holds that stop a night or a course, and a mailbag. The fill insert at the end prices a real US count. Jovin does not dispense.

The practitioner

One Lyon GP signs every cabinet note

Dr. Rosalind Hartley reviews each page and answers the mailbag. Nitrates and PDE5 tablets never mix. A penicillin allergy is not a footnote. An antibiotic course is finished or stopped by a clinician, not by a webpage.

Research centres

The labs and regulators the notes draw on

Sandwich, Bothell, Wuppertal, Rahway, Brockham Park, Silver Spring, Amsterdam. The history is here so the locks on the remedy pages have somewhere to point.

Former Pfizer Discovery Laboratories

Ramsgate Road, Sandwich, Kent CT13 9NJ, United Kingdom

The Kent site where sildenafil started out as UK-92,480, a hopeful angina candidate. The heart numbers were dull; the notes patients kept making about erections were not, and Pfizer turned the whole programme toward erectile dysfunction. Most of the modern PDE5 story opens on this road.

ICOS Corporation (historic)

22021 20th Avenue SE, Bothell, WA 98021, USA

The Washington biotech that worked out tadalafil and partnered with Eli Lilly to carry it through late trials. Its molecule left the body far more slowly than its rivals, and that one pharmacokinetic quirk became Cialis — the long-window tablet the category now measures itself against.

Bayer AG

Aprather Weg 18a, 42113 Wuppertal, Germany

The Wuppertal laboratories behind vardenafil, later sold as Levitra and the orodispersible Staxyn. Its compound is the most potent PDE5 inhibitor per milligram of the three, which is why the labelled doses read so much smaller than sildenafil's.

Merck Research Laboratories

126 East Lincoln Avenue, Rahway, NJ 07065, USA

The New Jersey labs that developed finasteride, first as the prostate drug Proscar and then, at a fifth of the dose, as Propecia for male-pattern hair loss. The insight came from studying men born without working 5-alpha-reductase — a natural experiment that pointed straight at the enzyme.

Beecham Research Laboratories (historic)

Brockham Park, Betchworth, Surrey RH3 7AJ, United Kingdom

The Surrey research site where Beecham chemists built the semisynthetic penicillins, amoxicillin among them, in the early 1970s. Adding a single hydroxyl group to ampicillin gave a molecule the gut absorbs far better — the reason amoxicillin, not ampicillin, sits in most medicine cabinets today.

U.S. Food and Drug Administration

10903 New Hampshire Avenue, Silver Spring, MD 20993, USA

The American regulator whose approved prescribing information sets the doses, boxed cautions and interaction rules we quote. When a page here and the current FDA label disagree, the label is the authority — the nitrate contraindication for the PDE5 drugs above all.

European Medicines Agency

Domenico Scarlattilaan 6, 1083 HS Amsterdam, Netherlands

The EU agency whose scientific assessments and product information sit beside the FDA label in our reading. Its reviews are especially useful for the European brands and for the reasoning behind each approved indication.
