Acetaminophen (Paracetamol) associated serious skin reactions:

v FDA notified healthcare professionals and patients that Acetaminophen (Paracetamol) has been associated with a risk of rare but serious skin reactions including Stevens - Johnson syndrome (SJS), Toxic Epidermal Necrolysis (TEN), and Acute Generalized Exanthematous Pustulosis (AGEP) which can be fatal.

v These reactions can occur with first-time or any time use of Acetaminophen (Paracetamol).

v Health care professionals should be aware of this rare risk of Acetaminophen (Paracetamol) induced serious skin reactions.

v Patients should stop taking the product immediately when they develop a rash or other skin reaction and seek medical attention right away.

Evolocumab - New Drug to Lower ‘LDL' Cholesterol:

  

Evolocumab is a "human monoclonal antibody".

  It is an inhibitor of Proprotein Convertase Subtilisin/Kexin type 9 (PCSK9).

  PCSK9 is produced by liver and is a regulatory protein which targets LDL receptors for degradation. Hence, LDL receptors would be least available to remove LDL-C (Bad cholesterol), from the blood.

  Inhibition of PCSK9 increases the number of LDL receptors on the surface of liver cells which leads to reduction of LDL levels in the bloodstream.

  According to the results of a global trial, Evolocumab can further knock down cholesterol levels in people who take cholesterol-busting statin medications.

  Evolocumab will be mostly helpful in treating people with a genetic disorder that causes them to have high cholesterol and the people with high cholesterol who can't take large doses of statins.

  It is a very specific antibody and it seems to be very well-tolerated without any drug interactions or any side effects.

  Evolocumab is under evaluation and once it gain U.S. Food and Drug Administration approval, the drug will be expensive.

Antibiotic Resistance:



p The ability of pathogens that works against the antibiotics is termed Antibiotic Resistance.
p Antibiotic resistance may be caused by many factors including…
Ø Overuse
Ø Misuse
Ø Availability of OTC antibiotics
Ø Healthcare Workers
Ø Hospitalized Patients
Ø Animal Feed
Ø Antibiotics in food and water
Ø Antibiotic resistance in genetically modified crops
p There are three types of Antibiotic resistance such as…
Ø Natural or inherent resistance
Ø Mutational resistance
Ø Acquired (Extrachromosomal) resistance
p Bacterial resistance may be developed by the mechanisms like…
Ø Enzymatic degradation of the drug
Ø Modification of the drug's target
Ø Reduced permeability of the drug
Ø Efflux pumping of Antibiotics
Ø Modification of Target ribosomes
Ø Alteration of Pathway
p Antibiotic resistance may be reduced by
Ø Stop unnecessary antibiotic prescriptions
Ø Complete the course of antibiotic prescriptions
Ø Promote Vaccine recommendations
Ø Implement infection control measures, such as hand washing, isolation precautions, and immunization
Ø Improve communication, education and training.

Negative Effects of "Skipping Breakfast":



¢ Breakfast is the most important meal of the day.
¢ Skipping breakfast may leads to
  Elevated risk of Coronary Heart Disease (CHD)
  Disruption of Metabolism
  Weight Gain
  Type 2 Diabetes Mellitus
  Impaired Lipid Level
  Lowered concentration level
¢ The risk of Coronary Heart Disease (CHD) is elevated by impairment of insulin sensitivity and serum lipids caused by skipping of breakfast.
¢ Obesity may be induced by breakfast skipping through disruption of metabolism.
¢ Breakfast skipping may lead to weight gain due to intense eating in the afternoon.
¢ The risk of Type 2 Diabetes Mellitus is increased by insulin resistance induced by skipping of breakfast.
¢ The concentration, memory and coordination may be lowered by reduced blood supply to the brain which is caused by breakfast skipping.
¢ Anything to eat at breakfast is better than going hungry.
¢ Even “Ritual Fasting” or “Fasting Therapy” makes way for the breakfast.
¢ "Don't skip breakfast"

High Alert Medications:





More presentations from Naina Mohamed Pakkir Maideen

Ø High alert Medications (HAMs) are the drugs or medications having heightened risk of causing significant patient harm when they used in error.
Ø Hypertonic electrolytes solutions are considered as High Alert Medications due to their nature of abundant release of electrolytes in to the bloodstream.
Ø Hypertonic Calcium Chloride Injection:
·       It is indicated in Cardiac Resuscitation, Hypocalcemic Tetany, Magnesium Sulphate overdose and lead coli.
·       It is Contraindicated in Ventricular Fibrillation.
·       Overdose of Calcium Chloride 10% Injection leads to Hypercalcemia. If not treated it may cause confusion, delirium and coma followed by death.
·        Overdose of Calcium Chloride 10% Injection is treated by 4–6 L of intravenous saline over the first 24 h to treat Dehydration and by loop diuretics to enhance sodium and calcium excretion.
Ø Hypertonic Magnesium Sulphate Injection:
·       Magnesium sulphate is indicated in patients with Hypomagnesemia, Torsades de Pointes, Status Asthmaticus, Eclampsia & Pre eclampsia and Uterine Tetany.
·       Magnesium sulphate is Contraindicated in patients with Heart block, Myocardial damage and Impaired Renal function.
·       Overdose of Magnesium sulphate Injection leads to progressive weakness of respiratory muscles leading to respiratory failure. If not treated it may cause hypoxia, ischemia and cardiac arrest.
·       Overdose of Magnesium sulphate is treated by One ampoule of Calcium gluconate 1gm (10ml of 10% Solution) given intravenously for over 2-3 minutes.
Ø Hypertonic Potassium Chloride Injection:
·       It is indicated in Hypokalemia.
·       It is Contraindicated in Hyperkalemia and Renal failure.
·       Overdose of Hypertonic Potassium Chloride Injection may cause Paresthesias of the extremities, Muscular or respiratory paralysis, Mental confusion, Weakness, Hypotension, Cardiac arrhythmias, Heart block, Electrocardiographic abnormalities and Cardiac arrest.
·       Overdose of Hypertonic Potassium Chloride Injection can be treated by intravenous Dextrose Injection, USP, 10% or 25%, containing 10 units of crystalline insulin per 20 grams of dextrose and is administered 300 to 500 mL per hour.
Ø Insulins:
·       Insulin is indicated for the treatment of both Type 1 and Type 2 diabetes mellitus.
·       It is Contraindicated in Hypoglycemia.
·       Overdose of Insulin leads to hypoglycemia. If untreated it may cause impairment of brain functions, convulsions and coma followed by death.
·       Hypoglycemia and Hypokalemia caused by overdose of Insulin should be monitored.
