Pharm.- Sem III Roll No: 20 Department of Pharmacology L.M.COLLEGE OF PHARMACY Concept of Essential Medicines And Rational Drug UseRational means: Rational means Endowed with Reasoning Sensible Sane Moderate Not foolish ,absurd or extremeWhat is Rational Drug Use?: What is Rational Drug Use? Use of drugs which are efficient, safe, low- cost and easy to administer Use of right medicine for right indication to right patient at right time in right dose, route of administration and durationEssential medicines : Essential medicines The drugs to be used should be efficacious, safe, cost effective and suitable for use in a patient. These are the drugs contained in the list of essential medicines Essential medicines are those that satisfy the priority health care needs of the populationCriteria for selection of essential medicines: Criteria for selection of essential medicines Selected with due regard to: Disease prevalence Evidence on efficacy and safety Cost-effectiveness These are intended to be available within the context of functioning health systems at all times in adequate amount, In appropriate dosage form, With assured quality and At price that individual and community can affordContinue….: Continue…. WHO list of ED: 312 items and 518 formulations 21 FDCs and 36 formulations India: The National Essential Drug list: 279 items, 489 formulations, 11 FDCs Market: >1 lakh formulations, 70% FDCs Many are non-essential, useless, irrational and harmful.Causes of irrationality: Causes of irrationality Irrationality of 2 broader types: Irrational drug combinations prevalent in the market Irrational use of rational, essential drugs availableSome common irrational prescription & treatment practices: Some common irrational prescription & treatment practices Prescribing antibiotics for ailments like protozoal or viral infection-antibiotic resistance Combination products where one drug is sufficient Prescribing unnecessary expensive vitamins or tonics, virtually regardless of condition being treatedContinue….: Continue…. Prescribing expensive drugs in preference to established less expensive ones Ordering for unnecessary investigationsWho is responsible?: Who is responsible? Patient pressure: You must give instant relief A belief of pill for every ill Changing physician/ hosp, simultaneous treatment from different system of medicines Injections are more efficatious Social taboos- fasts Non- complianceContinue….: Continue…. Practice pressure I must succeed(as may be the deal with pharma companies) The latest is the best Costlier is better The patient demand it(or I lose my practice or patient will go to other doctor) The more I write the more I earn Too many patients, too little timeAbove all….: Above all…. The Pharmaceutical companies and Government The amendment of D & C act,1982 had given the govt. enough power to prohibit mfg and sale of Irrational FDCs. Most irrational FDCs marketed by companies are permitted by State Drug Authorities--- clear violation to the LAWSteps to improve rational drug prescribing: Steps to improve rational drug prescribing Step 1 Identify the patient’s problem based on symptoms & recognize the need for action Step 2 Proper diagnosis of the disease. Step 3 List only possible intervention or treatmentContinue….: Continue…. Step 4 Start the treatment by writing an accurate & complete prescription: name of drugs with dosage form, dosing schedule & Total duration of actionContinue….: Continue…. Step 5 Give proper information, instruction & warning w.r.t treatment given side effects & Potential benefits Action to be taken in case of missed dose Danger/risk of stopping therapy suddenly ‘To do’ and ‘not to do’ during therapyContinue…: Continue… Step 6 Monitor the treatment to check, if particular treatment has solved the patient’s problem: Passive monitoring:- by patient himself Active monitoring:- by physicianFDCs: Rational or irrational: FDCs: Rational or irrational Basis of rationality of FDCs: The drugs in combination should act by different mechanism. The pharmacokinetics must not be widely different The comb. should not have supra-additive toxicity of the ingredients. Special benefit with cost-effectiveness.Continue….: Continue…. Irrational FDCs introduced in India: Paediatric formulation of nimesulide + paracetamol Diclofenac + serratopeptidase Quinolones & nitroimidazoles e.g. norfloxacin + metronidazole ciprofloxacin + tinidazole ofloxacin + ornidazole To cover up diagnostic imprecision& the lack of access to lab facilitiesContinue…: Continue… CIMs,2006:- >100 irrational combination brands The monthly index of medical Specialties, june2007:- 136 irrational combinationsIrrational combination as listed by CIMs in 2006: Irrational combination as listed by CIMs in 2006 FDCs Irrationality NO. of brands available Nimesulide + Paracetamol Enalapril + Losartan Nimesulide banned No evidence that combination is more effective than single Increased side – effects Both affecting same pathway do not add to efficacy 21 3Continue….: Continue…. FDCs Irrationality No. of brands available Norfloxacin + Tinidazole Atorvastatin + Nicotinic acid Cetrizine + Phenylpropanolamine + Paracetamol Patient suffer from only one type of diarrhoea (bacterial or protozoal ), may encourage resistance Probability of myopathy may increase PPA is banned due to its potential to cause Stroke, Glaucoma & Prostate enlargement 47 4 6Continue….: Continue…. FDCs Irrationality No. of brands available Amoxicillin + Cloxacillin Amoxicillin is inactive against Staphylococci & cloxacillin is not very active against streptococci, One of the components is useless for any given infection Amount of each drug is halved & chances of resistance increases. 27Irrational Combinations And Banned Drugs: Irrational Combinations And Banned Drugs The DCGI has allowed so many drugs having serious ADR after considering their therapeutic justification but those drugs are allowed with an indication to be printed on label of product i.e. Erythromycin, Chloramphenicol , Metronidazole , Iodo-chlorohydroxy quinoline etc.Continue….: 1.
