The cost is negligible and it saves time on the part of both families and out-of-hours health professionals. Typical maximum doses are described on page 22, but the doses needed by individuals vary widely: it is more important to assess the effectiveness of each p.r.n. before repeating or increasing doses – if a p.r.n. is ineffective, try a different approach or seek advice (see flow diagrams) A typical “pre-emptive p.r.n.” regimen for patients approaching the end of life might include: Morphine sulphate 2.5-5mg 1-4 hourly p.r.n.

  • Bioavailability and Bioeqivalence
    UNIT 5 BIOAVAILABILITY AND BIOEQIVALENCE S. SANGEETHA., M.PHARM., (Ph.d) Department of Pharmaceutics SRM College of Pharmacy SRM University BIOAVAILABILITY INTRODUCTION ¾The bioavailability or systemic availability of an orally administered drug depends largely on the absorption and the extent of hepatic metabolism ¾The bioavailability of an oral dosage form is determined by comparing the Area Under Curve (AUC) after oral administration of a single dose with that obtained when given IV Drug bioavailability = AUC (oral) AUC (IV) = Bioavailable dose Administered dose DEFINITION Bioavailability is defined as the rate and the absorption of drug that reaches the biological system in an active form, capable of exerting the desired pharmacological effect, including its onset, intensity and duration of its action. THE NEED FOR BIOAVAILABILITY STUDIES ¾Bioavailability studies provide and estimate of the fraction of the orally administered dose that is absorbed into the systemic circulation when compared to the bioavailability for a solution, suspension, or intravenous dosage form that is completely available. ¾Bioavailability studies provide other useful information that is important to establish dosage regimen and to support drug labeling, such as distribution and elimination characteristics of the drug ¾Bioavailability studies provide information regarding the performance of the formulation TYPES OF BIOAVAILABILITY Absolute bioavailability – Absolute bioavailability of a drug in a formulation administered by an extravascular, including the oral route reaching the systemic circulation is the fraction of the same dose of the drug administered intravenously. Absolute bioavailability= (AUC) abs (AUC) iv Absolute bioavailability = (AUC) abs x Div (AUC) iv x Dabs Where Dabs is the size of the single dose administered via the absorption site And Div is the dose size administered intravenously.

  • Tube Feeding Using the Bolus Method | Memorial Sloan Kettering Cancer Center
    PATIENT & CAREGIVER EDUCATION Tube Feeding Using the Bolus Method This information will help teach you how to use the bolus method to feed yourself and take your medications through your percutaneous endoscopic gastrostomy (PEG), gastrostomy tube (GT), or nasogastric tube (NGT). About Tube Feeding Tube feeding is when you get your nutrients through a feeding tube if you aren’t able to get enough through eating and drinking, or if you can’t swallow safely. Nutrients provide energy and help you heal. The bolus method is a type of feeding where a syringe is used to send formula through your feeding tube. The syringe you’ll use is called a catheter syringe. A catheter syringe doesn’t have a needle. It has a hole with a plunger in it. You draw up formula through the hole in the syringe then push the formula into your feeding tube with the plunger. A bolus refers to 1 “meal” of formula. You may have a feeding tube with a legacy connector or an ENFit connector. In this resource, we’ll show images of both types of connectors. For more information about your feeding tube, including how to manage side effects, read Tube Feeding Troubleshooting Guide. Tube Feeding Using the Bolus Method 1/11 Tube Feeding Guidelines Formula: __________ Total cans per day: ____________________ (8 ounces each) Calories per day: __________ You can choose the times of your feedings, as long as you reach your daily nutritional goals. Write in the times you prefer or your doctor, advanced practice provider (APP), or clinical dietitian nutritionist recommends.

  • Dynamic Analysis of Cardiovascular Drugs Data
    Available online www.jocpr.com Journal of Chemical and Pharmaceutical Research, 2014, 6(5):1517-1520 ISSN : 0975-7384 Research Article CODEN(USA) : JCPRC5 Dynamic analysis of cardiovascular drugs data Humei Yang and SunShi The Affiliated Hospital of Qingdao University Medical College , China _____________________________________________________________________________________________ ABSTRACT Cardiovascular disease is an important disease which is a serious hazard to human health, not only that, but the cause is still quite complicated. Therefore, it is very important to carry out research work of cardiovascular drugs in the medical profession. In this article, the money amount sequence method and DDD number sequence method were used to statistically analyze the data of cardiovascular drugs which were purchased by patients in a hospital in Shanghai in 2010-2013 year. The data of cardiovascular drugs second-class hospitals and upper-class hospitals in Shanghai included the drug varieties, prescription medication, the amount of money, which were statistically analyzed in order to provide recommendations for future cardiovascular medication guide. Through this research, we have come to the result that the money of cardiovascular drugs accounts greater of the amount of all of the drugs in the second-class hospitals than that in the upper-class hospitals, and cardiovascular medication amounts, prescriptions, etc of the second-class hospitals and upper-class hospitals had increased than before. Calcium antagonists and angiotensin ⅱ receptor antagonist drugs led occupation, as well as a small amount of varieties of drugs had gone into the top 10 amounts .As for cardiovascular drugs, foreign markets occupy a major market. That is to say that between different levels of hospitals there is some difference in cardiovascular drug use, but the drugs with good effects are already the first choice.
