Concept of clearance & factors affecting renal excretionchiranjibi68
This document discusses the concept of renal clearance. It defines renal clearance as the volume of blood or plasma completely cleared of unchanged drug by the kidney per unit time. Renal clearance is calculated as the rate of urinary excretion divided by the plasma drug concentration. Several factors can affect renal clearance, including the physiochemical properties of the drug, plasma drug concentration, distribution and binding characteristics, urine pH, blood flow to the kidneys, biological factors, drug interactions, and disease states. Renal clearance is an important concept for understanding how drugs are eliminated from the body through the kidneys.
The document discusses drugs used to treat asthma. It describes asthma as a chronic inflammatory airway disorder characterized by wheezing, breathlessness, and reversible airflow obstruction. It outlines the classification of asthma drugs into short-term relievers for acute symptoms and long-term controllers to reduce symptoms and prevent attacks. Short-term relievers include beta-2 adrenergic agonists, methylxanthines, and antimuscarinic agents. Long-term controllers include inhaled corticosteroids, leukotriene pathway antagonists, and mast cell stabilizers.
Diuretics act by inhibiting sodium reabsorption in the nephron, increasing sodium and water excretion and reducing extracellular fluid volume. They are classified based on their site of action - carbonic anhydrase inhibitors (site 1), loop diuretics (site 2), thiazides (site 3), and potassium-sparing diuretics (site 4). Loop diuretics like furosemide are sulfonamide derivatives that act distinctly on the loop of Henle. Thiazide diuretics like hydrochlorothiazide are benzothiadiazine derivatives that inhibit sodium reabsorption in the distal convoluted tubule. Potassium-sparing diuretics include sodium channel blockers
UTIs are caused by bacterial infections in the urinary tract. They range from cystitis, an infection of the bladder, to pyelonephritis, a serious infection of the kidneys. The most common pathogen is E. coli. Treatment depends on the severity and location of the infection, with acute uncomplicated cystitis usually treated with a 3 day course of antibiotics like cotrimoxazole or cephalexin. More serious or complicated infections may require 7-14 days of treatment with intravenous antibiotics such as gentamicin and third generation cephalosporins. Chronic infections necessitate long term suppressive antibiotic therapy after identifying and addressing any underlying causes.
This document provides information on rheumatoid arthritis (RA) including its symptoms, causes, pathophysiology, diagnosis, and treatment.

The goals of treatment are to reduce joint damage, pain, disability and maintain quality of life while minimizing adverse effects.
This document discusses peptic ulcers, including their causes, symptoms, and treatments. It notes that peptic ulcers are open sores in the upper digestive tract that can form in the stomach (gastric ulcer) or small intestine (duodenal ulcer). Common causes include H. pylori infection, NSAIDs, and stress. Symptoms may include abdominal pain, nausea, black stools, or weight loss. Treatments discussed include antibiotics to kill H. pylori, antacids to neutralize stomach acid, drugs that decrease acid secretion, ulcer protective drugs to coat the ulcer, and ulcer healing drugs.
This document discusses drugs used to treat urinary tract infections. It begins by defining urinary antiseptics as oral agents that exert antibacterial effects in the urine but have little systemic effects, making them useful for lower urinary tract infections. The main urinary antiseptics discussed are nitrofurantoin, metenamine, and nalidixic acid. The document then provides details on the mechanisms of action, uses, and side effects of each drug. It concludes by discussing factors like urinary pH that influence drug effectiveness and challenges in treating urinary infections in patients with renal impairment.
This document outlines general principles for the treatment of poisoning and management of common drug poisonings. It discusses stabilization of airway, breathing, circulation and CNS depression as priorities. Evaluation, decontamination including gastric lavage and activated charcoal, and poison elimination methods are reviewed. Specific treatments for paracetamol, salicylate, organophosphate and other poisonings are provided. The document serves as a guide for clinicians on managing poisoning cases.
The document discusses expectorants and antitussives. It defines expectorants as drugs that increase bronchial secretion or reduce viscosity, facilitating removal by coughing. Only guaiphenesin is approved as an expectorant in the U.S. Expectorants are classified as bronchial secretion enhancers or mucolytics. Antitussives act in the CNS to suppress cough or act peripherally in the respiratory tract. Antitussives are classified as opioids, nonopioids, antihistamines, or peripherally acting drugs. The document provides examples and doses of expectorants and antitussives and discusses some combination antitussive-expectorant formulations.
Gout is caused by elevated levels of uric acid in the blood which can crystallize and deposit in the joints, causing inflammation and pain. It is usually characterized by recurrent attacks of inflammatory arthritis in the joint at the base of the big toe. Treatment involves medications like NSAIDs to reduce inflammation during acute attacks and allopurinol or probenecid for long-term prevention by lowering uric acid levels through inhibition of uric acid synthesis or reabsorption. Lifestyle changes and a diet low in purine-rich foods can also help prevent gout attacks.

Digestants are substances intended to promote digestion by supplying digestive enzymes. Examples include hydrochloric acid, pepsin, papain, pancreatin, and diastase. They may be beneficial in conditions where enzyme production is deficient but their routine use is generally not recommended. Side effects of digestants can
This document discusses anti-leprotic drugs used to treat leprosy, which is caused by Mycobacterium leprae. It outlines the classification, mechanisms of action, adverse effects, and resistance issues of main drugs used including dapsone, clofazimine, rifampin, ofloxacin and minocycline. It also describes multidrug therapy regimens introduced by WHO using combinations of these drugs to shorten treatment duration and prevent resistance. Alternative regimens are discussed for cases of rifampin resistance. Reactions during leprosy treatment like lepra reaction are also summarized.
Drug distribution involves the reversible transfer of drugs between compartments like blood and tissues. Several factors affect how drugs are distributed, including tissue permeability, organ size and blood flow, and binding to tissue components. Drugs with certain physicochemical properties like small molecular size and appropriate lipophilicity more easily pass through barriers and cell membranes into tissues. Additionally, tissues with greater blood flow and perfusion rates allow for faster drug distribution. Finally, the extent to which drugs bind to proteins and other components in blood and tissues impacts their distribution.
Barbiturates are drugs derived from barbituric acid that were introduced clinically in 1934. Thiopental sodium is an ultra short-acting barbiturate used for intravenous anesthesia induction. It works by facilitating the action of the neurotransmitter GABA at GABAA receptors in the brain, which depresses the central nervous system. Thiopental has high protein binding, redistributes to tissues like fat and muscle, and is slowly metabolized and eliminated from the body, giving it a long context-sensitive half-life. Its mechanism of action, pharmacokinetics, therapeutic uses, and potential complications are described in detail in the document.
- Atropine is an anticholinergic drug that blocks muscarinic receptors throughout the body. It has many effects including stimulation of the central nervous system, tachycardia, dilation of the pupils, decreased secretions, and relaxation of smooth muscles.

This document provides information on intravenous induction agents used in anesthesia. It discusses the ideal properties of IV induction agents and describes several common agents in detail including propofol, thiopental, benzodiazepines, and ketamine. Propofol is a widely used agent that acts on GABA receptors to cause sedation. Thiopental and barbiturates also act on GABA receptors while ketamine is unique as a non-GABA agent that acts on NMDA receptors to produce a dissociative state. Each drug has benefits and risks regarding onset, duration, and effects on respiration and circulation.
Thiopentone (also known as thiopental sodium) is a short-acting barbiturate used for inducing anesthesia. It works by enhancing the effects of the neurotransmitter GABA at GABAA receptors in the brain, which increases chloride conductance and inhibits neuronal activity. Thiopentone is administered intravenously as a 2.5% solution for induction of anesthesia in adults and children. Common side effects include respiratory depression, hypotension, and pain or tissue damage if accidentally injected into an artery. Proper dosage depends on factors like age, weight, and medical history. Thiopentone is metabolized in the liver and redistributes rapidly from the brain after administration, which allows for quick awakening.

2. BARBITURATE POISONING
•It is the poisoning caused due to overdose of
barbiturates e.g.. Phenobarbitone.
•The lethal dose of 6 – 10 gm is sufficient to cause acute
barbiturate poisoning .
•Short acting barbiturates are more lethal than short
acting ones .
•Coma is more Sevier with barbiturate poisoning .
4. MECHANISM OF ACTION OF POISONING
BARBITURATE
CAUSING GENERALIZED DEPRESSION
DRUG INTERACTS WITH BARBITURATE RECEPTORS
LEADS TO INCREASE IN GABA-mediated chloride channel currents
CAUSING SYNAPTIC INHIBITION
5. NOTE : while this mechanism takes place ,there also occurs a central
sympathetic tone depression leading to hypotension .
TREATMENT : The barbiturate poisoning has no specific antidote but there are
some measures taken which are as follows :
Gastric lavage followed by administration of activated charcoal to prevent
further absorption of barbiturates.
Maintenance of patent airway , adequate ventilation and oxygen
administration
General supportive measures like maintenance of blood pressure and body
fluid balance .
Forced alkaline diuresis with sodium bicarbonate , a diuretic (frusemide) and
IV fluids which will help to fasten the excretion of long acting barbiturates .
7. • Forced alkaline diuresis is a procedure commonly used for treatment of
barbiturate poisoning.
• In this 1.5-2.0 litres of I.V. fluids is administered per hour for 3 hours .
• It is done to maintain urine volume up to more than 500 ml per hour.
• Urine pH is measured every 30 min and the pH of between 7.5 and 8.5 is
maintained.
• Alkaline diuresis should be discontinued after 1 hour if the urine flow is
less than 3 ml per minute.
• Otherwise , it should be continued beyond 3 hours at 1 litre per hour until
blood salicylate is reduced to or less than 2.5 m mol per litre.
