WHAT IS PRESCRIPTIONA prescription, often abbreviated ? or Rx, is a health care program implemented by a physician or other qualified health care practitioner in the form of instructions that govern the plan of care for an individual patient.ELABORATE THE PARTS OF PRESCRIPTIONPredating modern legal definitions of a prescription, a prescription traditionally is composed of four parts: a superscription, inscription, subscription, and signature.It isimportant to know the possible drug interactions as these can cause serious adverse reactions or result in failed therapy.Part of prescription:-· Date· Name ,age ,sex, and address of the patient· Superstition· Inscription· Subscription· Signature· Renewal instruction· Signature,adress ,and registrations numberType of durg interactionDrug-drug InteractionsDrug-drug interactions result when two or more drugs react with each other. Such drugs can be from a combination of prescription drugs and/or over-the-counter (OTC) medications. Drugs with a narrow therapeutic range (little difference between therapeutic and lethal dose) are more likely to face incidents of serious drug interactions.For example:Taking digoxin with antibiotics like erythromycin or clarithromycin will increase the toxicity of digoxin because antibiotics affect the liver enzymes, causing digoxin to be metabolized (inactivated) slower. Similarly, the concurrent use of methotrexate and ibuprofen may result in increased methotrexate toxicity due to inhibition of kidney excretion by ibuprofen.The effectiveness of drugs may be reduced in situations where the action of one drug diminishes the action of the other. Some antibiotics reduce the effectiveness of oral contraceptive pills by impairing the bacterial flora responsible for recycling the hormone from the gut. Also, drugs like charcoal or magnesium carbonate should preferably not be taken at the same time as other drugs as they may impair absorption.Side effects of medications are intensified when drugs with the same effect are taken together. For instance, taking codeine (painkiller) with a cough syrup like procodin will increase the sedative effect. Aspirin, which is anti-platelet, increases the risk of bleeding when given together with warfarin, heparin or anti-depressants. There is also an increased risk of hepatotoxicity (liver damage) when isoniazid and paracetamol are used together.Drug-food interactionsThese interactions occur when drugs react with foods, dietary supplements or beverages (including alcohol). Some drugs may interfere with the body’s ability to absorb nutrients. In the same way, certain herbs and food can lessen or increase the impact of a drug.Smoking and drinking habits can have an adverse effect on drugs. Consumption of alcoholic drinks while on the antibiotic metronidazole will cause skin flushing, nausea, headache, and palpitations. Alcohol enhances the hypoglycaemic effect of anti-diabetic medication, and the hypotensive effect of many blood pressure drugs. It is best to avoid alcohol while on medications.The tobacco in cigarettes can also diminish the effectiveness of medications by increasing drug metabolism. Caffeine, which is found in tea, coffee, soft drinks and chocolate and some medications, can increase the risk of theophylline (a drug to treat asthma) toxicity.Certain foods cause drug interactions. People on warfarin have to avoid eating large amounts of green leafy vegetables like broccoli, spinach and watercress because the high vitamin K content of these foods counters the effect of warfarin.Grapefruit juice enhances the effect of drugs like simvastatin, nifedipine and ciclosporin, and its consumption should best be avoided. Dairy products which contain calcium reduce the absorption of biphosphonates, oral iron, levothyroxine and certain antibiotics e.g. ciprofloxacin and tetracycline.As for herbal or dietary supplements, there are some reports of interaction between warfarin and herbs such as garlic, Danshen, Dong Quai, ginseng, and ginkgo. These herbs may augment or reduce the effect of warfarin.Drug-disease interactionsDrug-condition interactions occur when a drug worsens or exacerbates an existing medical condition. For example, a nasal decongestant containing pseudoephedrine increases blood pressure and thus has to be avoided by people who are hypertensive (have high blood pressure).Asthmatic patients should be careful when using/buying over-the-counter NSAIDs like ibuprofenas they may cause airway constriction.Always inform your doctor about your condition/disease before the doctor prescribes a new drug. Conditions that place patients at high risk for drug interactions include kidney or liver disease, diabetes, asthma, cardiac problems, epilepsy, high or low blood pressure. Drug-disease interactions are more common among the elderly, who tend to have more diseases.In conclusion, people should inform healthcare professionals of their condition and any medications/dietary supplements that they are taking when visiting the doctor or purchasing medicines at the pharmacy. If a drug interaction is unavoidable, the patient will need to monitor the safety and efficacy of the drugs.

Post a ResponseWatch the video, The Science of Evolution, and address the following:Describe two things that you learned about DNA from the video.Tell what you found most surprising or interesting from the video and explain why.

A company called Nastech was involved in developing intranasal formulations of drugs to treat a variety of different diseases. Dr Steven Quay was a founder of Nastech; he (and his colleagues, including Dr Alexis Leonard) filed several patent applications covering his inventions; some of these patents were subsequently licensed or acquired by other companies. One of these patent applications was for intranasal formulations of carbetocin (an oxytocin analog), for possible treatment of autism and other conditions.Question 1:What is the patent number of the US granted patent described above?Answer 1:Question 2:What is the number of the corresponding US published applicationAnswer 2:Question 3:Compare the claims in the granted patent vs. the published application.
