SPIRONOLACTONE Spironolactone – Oral (Common Brand Name
SPIRONOLACTONE Spironolactone – oral (common brand name: Aldactone) Uses: Spironolactone is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. It is also used to treat swelling (edema) caused by certain conditions (e.g., congestive heart failure) by removing excess fluid and improving symptoms such as breathing problems. This medication is also used to treat low potassium levels and conditions in which the body is making too much of a natural chemical (aldosterone). Spironolactone is known as a “water pill” (potassium-sparing diuretic). Other uses: This medication has also been used to treat acne in women, female pattern hair loss, and excessive hair growth (hirsutism), especially in women with polycystic ovary disease. Side effects: Drowsiness, lightheadedness, stomach upset, diarrhea, nausea, vomiting, or headache may occur. To minimize lightheadedness, get up slowly when rising from a seated or lying position. If any of these effects persist or worsen, notify your doctor promptly. Tell your doctor immediately if any of these unlikely but serious side effects occur; dizziness, increased thirst, change in the amount of urine, mental/mood chances, unusual fatigue/weakness, muscle spasms, menstrual period changes, sexual function problems. This medication may lead to high levels of potassium, especially in patients with kidney problems. If not treated, very high potassium levels can be fatal. Tell your doctor immediately if you notice any of the following unlikely but serious side effects: slow/irregular heartbeat, muscle weakness. Precautions: Before taking spironolactone, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. -
The Pharmacology of Amiodarone and Digoxin As Antiarrhythmic Agents
Part I Anaesthesia Refresher Course – 2017 University of Cape Town The Pharmacology of Amiodarone and Digoxin as Antiarrhythmic Agents Dr Adri Vorster UCT Department of Anaesthesia & Perioperative Medicine The heart contains pacemaker, conduction and contractile tissue. Cardiac arrhythmias are caused by either enhancement or depression of cardiac action potential generation by pacemaker cells, or by abnormal conduction of the action potential. The pharmacological treatment of arrhythmias aims to achieve restoration of a normal rhythm and rate. The resting membrane potential of myocytes is around -90 mV, with the inside of the membrane more negative than the outside. The main extracellular ions are Na+ and Cl−, with K+ the main intracellular ion. The cardiac action potential involves a change in voltage across the cell membrane of myocytes, caused by movement of charged ions across the membrane. This voltage change is triggered by pacemaker cells. The action potential is divided into 5 phases (figure 1). Phase 0: Rapid depolarisation Duration < 2ms Threshold potential must be reached (-70 mV) for propagation to occur Rapid positive charge achieved as a result of increased Na+ conductance through voltage-gated Na+ channels in the cell membrane Phase 1: Partial repolarisation Closure of Na+ channels K+ channels open and close, resulting in brief outflow of K+ and a more negative membrane potential Phase 2: Plateau Duration up to 150 ms Absolute refractory period – prevents further depolarisation and myocardial tetany Result of Ca++ influx -

Pediatric Pharmacotherapy
Pediatric Pharmacotherapy A Monthly Review for Health Care Professionals of the Children's Medical Center Volume 1, Number 10, October 1995 DIURETICS IN CHILDREN • Overview • Loop Diuretics • Thiazide Diuretics • Metolazone • Potassium Sparing Diuretics • Diuretic Dosages • Efficacy of Diuretics in Chronic Pulmonary Disease • Summary • References Pharmacology Literature Reviews • Ibuprofen Overdosage • Predicting Creatinine Clearance Formulary Update Diuretics are used for a wide variety of conditions in infancy and childhood, including the management of pulmonary diseases such as respiratory distress syndrome (RDS) and bronchopulmonary dysplasia (BPD)(1 -5). Both RDS and BPD are often associated with underlying pulmonary edema and clinical improvement has been documented with diuretic use.6 Diuretics also play a major role in the management of congestive heart failure (CHF), which is frequently the result of congenital heart disease (7). Other indications, include hypertension due to the presence of cardiac or renal dysfunction. Hypertension in children is often resistant to therapy, requiring the use of multidrug regimens for optimal blood pressure control (8). Control of fluid and electrolyte status in the pediatric population remains a therapeutic challenge due to the profound effects of age and development on renal function. Although diuretics have been used extensively in infants and children, few controlled studies have been conducted to define the pharmacokinetics and pharmacodynamics of diuretics in this population. Nonetheless, diuretic therapy has become an important part of the management of critically ill infants and children. This issue will review the mechanisms of action, monitoring parameters, and indications for use of diuretics in the pediatric population (1-5). Loop Diuretics Loop diuretics are the most potent of the available diuretics (4). -

Cannabidiol (CBD) is increasingly used to treat epilepsy. The outbreak of the SARS-CoV-2 pandemic in 2019 created new challenges in the effective treatment of epilepsy in COVID-19 patients. The purpose of this review is to present data from the last few years on drug–drug interactions among of AEDs, as well as AEDs with other drugs, nutrients and food. Literature data was collected mainly in PubMed, as well as google base. The most important pharmacokinetic parameters of the chosen 29 AEDs, mechanism of action and clinical application, as well as their biotransformation, are presented.

NAMS Practice Pearl
NAMS Practice Pearl Extended Duration Use of Menopausal Hormone Therapy Released October 1, 2013 Andrew M. Kaunitz, MD, NCMP (University of Florida College of Medicine-Jacksonville, Department of Obstetrics & Gynecology, Jacksonville, FL) Although providing guidance to patients regarding duration of hormone therapy represents a topic surrounded by controversy, clinicians often encounter this issue in practice. As pointed out in the NAMS 2012 Hormone Therapy (HT) Position Statement, determining the optimal duration of HT is challenging both for clinicians and for patients. This Practice Pearl addresses clinical situations for which long-term HT might be appropriate and provides practical guidance regarding prudent therapeutic choices for women using HT for an extended duration. Use of Systemic HT to Treat Vasomotor Symptoms (VMS). Moderate to severe VMS represent the most common indication for systemic combination estrogen-progestin (EPT) or estrogen-only (ET) HT, and HT represents the most effective treatment for VMS.1 Some experts’ recommendations regarding HT duration of use have cautioned that “…it remains prudent to keep the… duration of treatment short” or that HT “…may serve a useful role in short-term symptom management.”2,3 However, VMS persist for longer than many have assumed. For instance, The Penn Ovarian Aging Study was conducted specifically to estimate the duration of moderate-to-severe VMS and found that median duration of such symptoms was 10.2 years. In this landmark cohort study, the median duration of VMS that started
