A systematized listing of drugs according to their primary actions, mechanisms, chemical nature, clinical uses and/or other relevant characteristics is the first step to learn about them. The mental exercise to prescribe a drug for a patient starts with identifying the class of drugs to be prescribed and then selecting the specific member most appropriate for that patient according to its subclass/group/individual characteristic. For example, the first thing one decides is whether an analgesic or an antihypertensive or an anti\biotic is to be prescribed; then proceeds to consider which type of analgesic (opioid/ nonopioid), or antihypertensive (β blocker/ACE inhibitor, etc.), or antibiotic (β-lactam/fluoroquinolone, etc.) is required and then which specific member is most suitable. On the other hand, every drug is known by its class and subclass, e.g. furosemide is a high-ceiling diuretic, glibenclamide is a sulfonylurea antidiabetic. As such, drug classifications are pivotal to pharmacology students and highly valuable to prescribing doctors. The phenomenal increase in the number of drugs in recent years has further underscored the need for drug classifications.

\ Drugclassificationshavebeencriticisedforbeingarbitraryandimperfectbecauseofnonuniformcriteriathathaveoftentobe adopted and frequent lack of watertight distinctions among drug groups/subgroups. Neverthe\less, basing on pharmacological differences and applying practical criteria, meaningful drug classifications can be devised. Though, any drug has multiple actions/properties, it can be designated by the most outstanding one. For example, labelling atenolol as a cardioselective β blocker summarises its actions, uses, etc. This booklet has adopted such a pragmatic approach and presented classifications of drugs that have been well accepted. The outstanding feature of the present edition is reformating of the classifications in the form of eye-catching charts. These charts create pictorial images and help memorizing. All classifications have been updated, modified where necessary and newer drugs have been included, particularly those marketed recently.

\ To be useful to medical/pharmacy students as well as to practitioners, the doses (including pediatric doses wherever relevant), frequency and route(s) of administra\tion along with leading brand names of drugs and different types of dosage forms (oral, parenteral, topical, etc.) are listed distinctively after each class of drugs. Thus, essential prescribing

information is incorporated for drugs that are available. Single drug formulations are mainly mentioned. Combined drug formulations find a place wherever important or relevant. The listing of brand names is restricted to only 1–4 per drug, and is not exhaustive. Synonyms and alternative names of drugs and classes of drugs are also mentioned. Two separate indices, one of nonproprietary (generic) names and the other of proprietary (brand) names of drugs is provided for instantaneous location of the drug or the product one is looking for.

\ It is hoped that the present user-friendly format of the booklet will make it a better aid to remembering drug names, identifying the class and subclass to which they belong, and provide easy access to core prescribing information. The credit for meticulous production of this booklet goes to the staff of M/s Jaypee Brothers.

ExplanatoryUnitedVRGNotes

1.\ The information on dosage form(s) is printed in maroon colour, and the proprietary (brand) names of drugs/products appear in capital letters.

2.\ The doses and regimens are given in smaller type, while nonproprietary (generic) drug names appear in bigger type and different font.

3.\ If no brand name of a drug is listed, it is not currently marketed in India, or is marketed only in combina\tions. This can be found out from the composition of the combined formulations given.

4.\ If the route of administration is not specified, the drug is administered only orally, and the dose mentioned is the oral dose.

5.\ Drug doses mentioned without specifying frequency of administration indicate the quantity for a single dose.
