The most common side effects associated with famotidine use include headache, dizziness, and constipation or diarrhea. [21] [22] Famotidine may contribute to QT prolongation, [23] particularly when used with other QT-elongating drugs, or in people with poor kidney function. [24]
Nephrotoxicity is toxicity in the kidneys. It is a poisonous effect of some substances, both toxic chemicals and medications, on kidney function. [1] There are various forms, [2] and some drugs may affect kidney function in more than one way. Nephrotoxins are substances displaying nephrotoxicity.
Proper kidney function depends upon adequate blood flow to the kidney. Kidney blood flow is a complex, tightly regulated process that relies on a number of hormones and other small molecules, such as prostaglandins. Under normal circumstances, prostaglandin E2 (PGE 2) produced by the kidney is necessary to support adequate blood flow to the kidney.
These differential effects are due to the different roles and tissue localisations of each COX isoenzyme. [11] By inhibiting physiological COX activity, NSAIDs may cause deleterious effects on kidney function, [12] and, perhaps as a result of water and sodium retention and decreases in renal blood flow, may lead to heart problems. [13]
Ranitidine has 10% of the affinity that cimetidine has to CYP450, so it causes fewer side effects, but other H 2 blockers famotidine and nizatidine have no CYP450 significant interactions. [ 131 ] Ranitidine was introduced in 1981, and was the world's biggest-selling prescription drug by 1987. [ 132 ]
Less-common side effects can include excess air or gas in your stomach, burping, heartburn, indigestion, fast heartbeat, low blood sugar, low energy and fatigue, or even gallstones, Dr. Comite says.
A simple means of estimating renal function is to measure pH, blood urea nitrogen, creatinine, and basic electrolytes (including sodium, potassium, chloride, and bicarbonate). As the kidney is the most important organ in controlling these values, any derangement in these values could suggest renal impairment.
