The ability to discriminate color differences decreases rapidly as the visual angle subtends less than 12' (0.2° or ~2 mm at a viewing distance of 50 cm), [5] so color stimulus of at least 3 mm in diameter or thickness is recommended when the color is on paper or on a screen. [6]
4-Hydroxycoumarins are a class of vitamin K antagonist (VKA) anticoagulant drug molecules. Chemically, they are derived from coumarin by adding a hydroxy group at the 4 position to obtain 4-hydroxycoumarin, then adding a large aromatic substituent at the 3-position (the ring-carbon between the hydroxyl and the carbonyl). The large 3-position ...
ATC code B01 Antithrombotic agents is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.

They are categorised as "first-generation" anticoagulants, and have similar effects as warfarin. They have been largely superseded by second-generation anticoagulants because warfarin-resistant rodents have become more common. [6] Anisindione, fluindione, and phenindione are oral anticoagulant medicines with actions similar to warfarin. However ...
The patent was assigned to the Wisconsin Alumni Research Foundation (WARF), [2] for which reason it was given the name Warfarin. [4] Link and researchers Stahmann and Ikawa jointly owning the patent. Initially marketed as rat poison , warfarin would later, in the 1950s, become the second most important anticoagulant for clinical use (after ...
Warfarin necrosis is a rare but severe complication of treatment with warfarin or related anticoagulants. [2] The typical patient appears to be an obese, middle aged woman (median age 54 years, male to female ratio 1:3). [1] [3]: 122–3 This drug eruption usually occurs between the third and tenth days of therapy with warfarin derivatives. [1]

The European Society of Cardiology (ESC), [21] and National Institute for Health and Care Excellence (NICE) [23] guidelines recommend that if the patient has a CHA 2 DS 2-VASc score of 2 and above, oral anticoagulation therapy (OAC) with a vitamin K antagonist (VKA, e.g. warfarin with target INR of 2-3) or one of the direct oral anticoagulant ...
