Cefadroxil Uses, Side Effects, and More

 Cefadroxil

Brand name:- Droxyl 0.5 ,cefadrox , Keffloxin 0.5 cap .0.25 Distab ,125mg/5ml susp.

Cefadroxil is an antibiotic. It kills bacteria by preventing them from forming the bacterial protective covering (cell wall) which is needed for them to survive.

Pharmacodynamic:-

Cefadroxil, a first-generation cephalosporin antibiotic, is used to treat urinary tract infections, skin and skin structure infections, pharyngitis, and tonsillitis.

Pharmacokinetics:-

Cefadroxil is almost completely absorbed from the gastrointestinal tract. After doses of 500 mg and 1 g by mouth, peak plasma concentrations of about 16 and 30 micrograms/ml, respectively, are obtained after 1.5 to 2.0 hours. Although peak concentrations are similar to those of cefalexin, plasma concentrations are more sustained. Dosage with food does not appear to affect the absorption of cefadroxil. About 20% of cefadroxil is reported to be bound to plasma proteins. Its plasma half-life is about 1.5 hours and is prolonged in patients with renal impairment.

Cefadroxil is widely distributed to body tissues and fluids. It crosses the placenta and appears in breast milk. More than 90% of a dose of cefadroxil may be excreted unchanged in the urine within 24 hours by glomerular filtration and tubular secretion; peak urinary concentrations of 1.8 mg/ml have been reported after a dose of 500 mg. Cefadroxil is removed by haemodialysis.

 Mechanism of action:- 

Cefadroxil is a semisynthesis first - generation cephalosporin antibiotic more effective against gram negative bacteria intended for oral adminstration for skin infection and respiratory tract infection. Cephalosporin are bactericidal because of their inhibition of cell wall synthesis.

Used:- 

Used to treat a wide variety of bacterial infections. It belongs to a class of drugs known as cephalosporin antibiotics.

Side effects:-

Stomach upset, nausea, vomiting, or diarrhea may occur.

 Dose:-  0.5 - 1g BD.

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...
