Clinical Information
Acetazolamide
one of the carbonic anhydrase inhibitors that is sometimes effective against absence seizures. it is sometimes useful also as an adjunct in the treatment of tonic-clonic, myoclonic, and atonic seizures, particularly in women whose seizures occur or are exacerbated at specific times in the menstrual cycle. however, its usefulness is transient often because of rapid development of tolerance. its antiepileptic effect may be due to its inhibitory effect on brain carbonic anhydrase, which leads to an increased transneuronal chloride gradient, increased chloride current, and increased inhibition. (from smith and reynard, textbook of pharmacology, 1991, p337)Amiloride
a pyrazine compound inhibiting sodium reabsorption through sodium channels in renal epithelial cells. this inhibition creates a negative potential in the luminal membranes of principal cells, located in the distal convoluted tubule and collecting duct. negative potential reduces secretion of potassium and hydrogen ions. amiloride is used in conjunction with diuretics to spare potassium loss. (from gilman et al., goodman and gilman's the pharmacological basis of therapeutics, 9th ed, p705)Bendroflumethiazide
a thiazide diuretic with actions and uses similar to those of hydrochlorothiazide. it has been used in the treatment of familial hyperkalemia, hypertension, edema, and urinary tract disorders. (from martindale, the extra pharmacopoeia, 30th ed, p810)Chlormerodrin
a mercurial compound that has been used as a diuretic but is now superseded by more potent and less toxic drugs. the radiolabeled form has been used as a diagnostic and research tool.Chlorothiazide
a thiazide diuretic with actions and uses similar to those of hydrochlorothiazide. (from martindale, the extra pharmacopoeia, 30th ed, p812)Chlorthalidone
a benzenesulfonamide-phthalimidine that tautomerizes to a benzophenones form. it is considered a thiazide-like diuretic.Clopamide
a sulfamoylbenzamide piperidine. it is considered a thiazide-like diuretic.Cyclopenthiazide
thiazide diuretic also used as an antihypertensive agent.Dichlorphenamide
a carbonic anhydrase inhibitor that is used in the treatment of glaucoma.Ethoxzolamide
a carbonic anhydrase inhibitor used as diuretic and in glaucoma. it may cause hypokalemia.Hydrochlorothiazide
a thiazide diuretic often considered the prototypical member of this class. it reduces the reabsorption of electrolytes from the renal tubules. this results in increased excretion of water and electrolytes, including sodium, potassium, chloride, and magnesium. it is used in the treatment of several disorders including edema, hypertension, diabetes insipidus, and hypoparathyroidism.Hydroflumethiazide
a thiazide diuretic with actions and uses similar to those of hydrochlorothiazide. (from martindale, the extra pharmacopoeia, 30th ed, p822)Mefruside
a benzene-sulfonamide-furan. it is used as a diuretic that affects the concentrating ability of the kidney, increases sodium chloride excretion, but may not spare potassium. it inhibits carbonic anhydrases and may increase the blood uric acid level.Mersalyl
a toxic thiol mercury salt formerly used as a diuretic. it inhibits various biochemical functions, especially in mitochondria, and is used to study those functions.Methazolamide
a carbonic anhydrase inhibitor that is used as a diuretic and in the treatment of glaucoma.Methyclothiazide
a thiazide diuretic with properties similar to those of hydrochlorothiazide. (from martindale, the extra pharmacopoeia, 30th ed, p825)Metolazone
a quinazoline-sulfonamide derived diuretic that functions by inhibiting sodium chloride symporters.Polythiazide
a thiazide diuretic with actions and uses similar to those of hydrochlorothiazide. (from martindale, the extra pharmacopoeia, 30th ed, p826)Triamterene
a pteridinetriamine compound that inhibits sodium reabsorption through sodium channels in renal epithelial cells.Trichlormethiazide
a thiazide diuretic with properties similar to those of hydrochlorothiazide. (from martindale, the extra pharmacopoeia, 30th ed, p830)Fosfomycin
an antibiotic produced by streptomyces fradiae.Tromethamine
an organic amine proton acceptor. it is used in the synthesis of surface-active agents and pharmaceuticals; as an emulsifying agent for cosmetic creams and lotions, mineral oil and paraffin wax emulsions, as a biological buffer, and used as an alkalizer. (from merck, 11th ed; martindale, the extra pharmacopoeia, 30th ed, p1424)Xipamide
a sulfamoylbenzamide analog of clopamide. it is diuretic and saluretic with antihypertensive activity. it is bound to plasma proteins, thus has a delayed onset and prolonged action.
Coding Guidelines
When coding an adverse effect of a drug that has been correctly prescribed and properly administered, assign the appropriate code for the nature of the adverse effect followed by the appropriate code for the adverse effect of the drug.
The appropriate 7th character is to be added to each code from block Poisoning by, adverse effect of and underdosing of diuretics and other and unspecified drugs, medicaments and biological substances (T50). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
Table of Drugs and Chemicals
The code is referenced in the Table of Drugs and Chemicals, this table contains a classification of drugs, industrial solvents, corrosive gases, noxious plants, pesticides, and other toxic agents.
According to ICD-10-CM coding guidelines it is advised to do not code directly from the Table of Drugs and Chemicals, instead always refer back to the Tabular List when doing the initial coding. Each substance in the table is assigned a code according to the poisoning classification and external causes of adverse effects. It is important to use as many codes as necessary to specify all reported drugs, medicinal or chemical substances. If the same diagnosis code describes the causative agent for more than one adverse reaction, poisoning, toxic effect or underdosing, utilize the code only once.
Patient Education
Drug Reactions
Most of the time, medicines make our lives better. They reduce aches and pains, fight infections, and control problems such as high blood pressure or diabetes. But medicines can also cause unwanted reactions, such as drug interactions, side effects, and allergies.
What is a drug interaction?
A drug interaction is a change in the way a drug acts in the body when taken with certain other drugs, foods, or supplements or when taken while you have certain medical conditions. Examples include:
- Two drugs, such as aspirin and blood thinners
- Drugs and food, such as statins and grapefruit
- Drugs and supplements, such as gingko and blood thinners
- Drugs and medical conditions, such as aspirin and peptic ulcers
Interactions could cause a drug to be more or less effective, cause side effects, or change the way one or both drugs work.
What are side effects?
Side effects are unwanted, usually unpleasant, effects caused by medicines. Most are mild, such as a stomachache, dry mouth, or drowsiness, and go away after you stop taking the medicine. Others can be more serious. Sometimes a drug can interact with a disease that you have and cause a side effect. For example, if you have a heart condition, certain decongestants can cause you to have a rapid heartbeat.
What are drug allergies?
Drug allergies are another type of reaction. They can range from mild to life-threatening. Skin reactions, such as hives and rashes, are the most common type. Anaphylaxis, a serious allergic reaction, is less common.
How can I stay safe when taking medicines?
When you start a new prescription or over-the-counter medicine, make sure you understand how to take it correctly. Know which other medicines, foods, and supplements you need to avoid. Always talk to your health care provider or pharmacist if you have questions about your medicines.
