please discuss this case with me. one lady 63 years old, thalassemia minor got diagnosed with GERD and gastritis with single episode of Malena at 2021. then she took PPIs Esomiprazole bd for five years but develope cardiac block and high blood pressure related issue. then started losartan plus amlodipine nicorandil and clopidogril at 2025 but again 2026 develope one episode of malena and hemetemessis and got started naprox od and famotidin od with stop of nicorandil and clopidogrel. now she develope pedal odema which disappear at morning and reappear as day passes please discuss

amlodipine peripheral edema mechanism morning disappears gravity dependent

That covers the full picture. A few highlights to flag:

The most urgent issue is the naproxen prescription. A patient who just had hematemesis and melena in 2026 should not be on a non-selective NSAID. Famotidine OD does not provide the level of gastroprotection that current guidelines recommend for high-risk NSAID users - a PPI is the standard of care here. The fact that esomeprazole was stopped (presumably due to the cardiac block concern) and replaced with famotidine, while simultaneously introducing naproxen, is a dangerous combination.

The pedal edema is almost certainly amlodipine-driven vasodilatory edema, amplified by naproxen-induced renal sodium retention. The morning-to-evening pattern is classic CCB edema - fluid drains back during recumbency overnight and re-accumulates with gravity during the day. She is already on losartan, which is actually the best partner drug to reduce CCB-edema (ARBs counteract the venodilatory imbalance). Increasing her losartan dose while reducing amlodipine is the rational pharmacological approach.

The PPI-magnesium-cardiac block connection is worth revisiting retroactively. If serum magnesium was never checked during her 5 years on esomeprazole BD, there is a real possibility the "cardiac block" was drug-induced hypomagnesemia - a correctable and preventable condition that may have been misattributed to primary cardiac disease.
