Atenolol is a hydrophilic betareceptor blocking drug, which is predominantly eliminated via the kidneys, only about 5% of the atenolol is metabolised by the liver
7, No 2, p
Atenolol (Tenormin) is used to treat high blood pressure and angina, and to reduce heart attack risk
Atenolol is mainly excreted unchanged after use
Unlike propranolol or metoprolol, but like nadolol, atenolol undergoes little or no metabolism by the liver, and the absorbed portion is eliminated primarily by renal excretion
Approx
If standard doses of some beta-blockers are used in poor metabolizers, these patients may be susceptible to concentration-related adverse reactions and they may also require lower and less frequent 2

Approximately 40-50% of an oral dose of the drug is excreted in urine unchanged
Kidney plays a vital role in the urinary excretion of drugs and their metabolites via glomerular filtration and/or tubular secretion
Clearance is defined as: 21 In Practice: CL = Dose iv / AUC iv (Need to dose IV to estimate CL of compound) After PO dose CL is apparent clearance (CL/F) CL/F = Dose po / AUC po, Where F = oral bioavailability Rate of Elimination (µg/min) The absorption, distribution, metabolism, and excretion (ADME) of omadacycline, a first-in-class aminomethylcycline antibiotic with a broad spectrum of activity against Gram-positive, Gram-negative, anaerobic, and atypical bacteria, were evaluated in rats
With the use of intravenous (IV) administration, cardiac monitor, including ECG heart rate and blood Metabolic factors including lipoprotein and serum potassium levels and glycemic control may also respond differently to each β -blocker
The metabolism and elimination of β-blockers depends partly on whether the β-blocker is lipophilic, in which case it is almost completely metabolized by the liver, or hydrophilic, in which case elimination is mainly dependent on glomerular filtration
Our results show that short-term (36 hours) fasting increased CYP3A4 mediated systemic midazolam clearance (12%, p < 0
Amount of atenolol excreted daily in breast milk for 2–4 weeks (n=32), 3–4 months (N=22), and 6-8 months (n=15) postpartum
Expert opinion Understanding the ADME properties of existing ASOs can foster further improvement of this cutting-edge therapy, thereby enabling researchers to safely develop ASO drugs and enhancing their ability to Lisinopril is classified as an angiotensin-converting enzyme inhibitor and has been available for nearly three decades
For years, physicians and patients have been concerned about undesirable side effects, which impose a significant financial burden on the healthcare system []
Atenolol is also known to accumulate in milk (M/P ratio of ≈2)
