BUMETANIDE

 BUMETANIDE


BRAND NAME:- BUMET ,1mg tab , 0.25mg/ml inj.

BUMETANIDE is similar to furosemide in all respects & sulfamyl diuretic , but is 40 times more potent. It induces very rapid diuresis and is highly effective in Pulmonary edema. 


PHARMACODYNAMIC:-
Bumetanide is a loop diuretic and works by decreasing the reabsorption of sodium by the kidneys. The main difference between bumetanide and furosemide is in their bioavailability and potency. About 60% of furosemide is absorbed in the intestine, and there are substantial inter- and intraindividual differences in bioavailability (range 10-90%). About 80% of bumetanide is absorbed, and its absorption does not change when it is taken with food. It is said to be a more predictable diuretic, meaning that the predictable absorption is reflected in a more predictable effect.[11] Bumetanide is 40 times more potent than furosemide for people with normal renal function. 


MECHANISM OF ACTION:-
Bumetanide interferes with renal cAMP and/or inhibits the sodium-potassium ATPase pump. Bumetanide appears to block the active reabsorption of chloride and possibly sodium in the ascending loop of Henle, altering electrolyte transfer in the proximal tubule. This results in excretion of sodium, chloride, and water and, hence, diuresis .


USES:-
used to reduce extra fluid in the body (edema) caused by conditions such as heart failure, liver disease, and kidney disease. 

SIDE EFFECTS:-
Common side effects include dizziness, low blood pressure, low blood potassium, muscle cramps, and kidney problems.[1] Other serious side effects may include hearing loss and low blood platelets. 

DOSE:- 1-5 mg oral OD in the morning,2-4 mg i.m/i.v (max.15mg/day in renal failure).

Chlorthalidone Uses, Side Effects, and More....

 Chlorthalidone  Brand name:- Hythalton 50,100mg , Hydrazide, Thalizide ( 12.5, 25) . Chlorthalidone is a diuretic which lowers blood pressure by removing extra water and certain electrolytes from the body. Over time it also relaxes blood vessels and improves blood flow. Pharmacodynamic:- Not 🚫 available.  Pharmacokinetics:- Chlortalidone is slowly absorbed from the gastrointestinal tract after oral ingestion. It has a long half-life and therefore a prolonged diuretic action, which results in continued diuretic effects despite a skipped dose. This prolonged action of chlortalidone despite missing doses may account for the higher efficacy of chlortalidone compared to the shorter half-life medication, hydrochlorothiazide. Chlortalidone is eliminated from the body mostly by the kidney, as unchanged drug. Thus, in persons with diminished kidney function, the clearance of chlortalidone is reduced and the elimination half-life is increased. As with other thiazide diuretics, ch...

Captopril Uses, Side Effects, and More

 Captopril Brand name:- Angiopril 25mg tab, Aceten, Captopril 12.5, 25mg tab. Captopril is an angiotensin converting enzyme (ACE) inhibitor. It works by reducing stress on the heart and relaxing blood vessel so that blood flows more smoothly and the heart can pump blood more efficiently. Pharmacodynamic:-  Captopril, an ACE inhibitor, antagonizes the effect of the RAAS. The RAAS is a homeostatic mechanism for regulating hemodynamics, water and electrolyte balance. During sympathetic stimulation or when renal blood pressure or blood flow is reduced, renin is released from the granular cells of the juxtaglomerular apparatus in the kidneys. In the blood stream, renin cleaves circulating angiotensinogen to ATI, which is subsequently cleaved to ATII by ACE. ATII increases blood pressure using a number of mechanisms. First, it stimulates the secretion of aldosterone from the adrenal cortex. Aldosterone travels to the distal convoluted tubule (DCT) and collecting tubule of nephrons w...
