SGLUT 2 inhibitor

SGLUT-2 inhibitors: Act on kidney– Cana gliflozin– Dapa gliflozin 🌴 MOA-Block SGLU-2 in PCT → Decrease glucose reabsorption → more glucose excreted in urine, lowering blood sugar levels. 🟡 S/E- SGLT2 inhibitors make glucose pass into urine → urine becomes sugar-rich → bacteria grow easily → ↑ risk of UTI (and fungal infections). 🚨 SGLUT-2 […]

Laplace’s law

Laplace’s Law describes the relationship between pressure, surface tension, and radius in curved surfaces like bubbles, blood vessels, or alveoli in the lungs. For a spherical structure For a cylindrical structure P = 2T / r P = pressure inside the sphere (alveoli) T = surface tension r = radius of the sphere P =
