1. Critical illnesses are often associated with circulatory, respiratory, hepatic and/or renal dys­function that may alter the pharmacokinetics and/or pharmacodynamics of drugs.
2. Decisions about routes of administration and doses of drugs used during medical emergen­cies must consider the physiological status of the patient, the pharmacokinetic and pharmacodynamic characteristics of the particular drug, and how the two interact.
3. Adverse drug reactions and interactions are more likely in critically ill patients due to the effect of the disease on drug kinetics, the decreased toxic-therapeutic ratio due to severe under­lying illness, and the large number of medications that such patients receive. Adverse reactions to drugs should be considered when unexplained deterioration or failure to respond to therapy are encountered.
4. Preservation of function of vital organs is a fundamental concept of critical care therapeutics. Preservation of cardiovascular functions requires attention to fluid and electrolyte status, prompt correction of arrhythmias and shock, and measures to preserve the myocardium against ischaemic injury.
5. Preservation of respiratory function requires protection of the airway, cautious use of fluids and oxygen, and prompt recognition and management of infection.
6. Preservation of cerebral function requires maintaining cerebral blood flow with adequate oxygen and glucose sufficient to meet the metabolic demands of the brain. This entails main­taining adequate systemic circulation, control of intracranial hypertension, and prompt control of seizures and hyperthermia.



7. Critically ill patients are particularly susceptible to infections, gastric stress erosions and ulcers, adult respiratory distress syndrome, pulmonary emboli, and haemostatic disorders. The risks of such complications may be reduced by meticulous care of catheters, pulmonary toilet, cautious use of fluids, prompt treatment of infection when it occurs, and selective prophylactic drug therapies.
8. Shock can be produced by many different processes including myocardial infarction, hypovolaemia, sepsis, drug overdose, burns, hypothermia, spinal cord transsection and anaphylaxis. Optimum treatment of shock depends on knowledge of the pathophysiology of the shock state and the pharmacology of the drugs.
9. Features of acute drug intoxication include coma, agitated delirium, seizures, hypo- and hyperthermia, shock, arrhythmias, aspiration and pulmonary oedema. Successful therapy of acute drug intoxication depends on the integration and application of knowledge of the pharmacology of both the intoxicating drug and the drugs used in therapy, as well as the principles of supportive critical care.

1. The main aim of anaesthesia is the prevention of pain during surgery and at other times.
2. Anaesthesia involves a balanced approach, in which the individual patient’s psyche and pathophysiology are taken into account and drugs are used to modify and control any aspect as required.
3. The decision to use a particular drug or technique must be made after careful consideration of the pathophysiological features of the individual case and how these may affect the phar­macokinetic handling and tissue response to the drugs available.
4. Any associated disease or pathophysiological abnormality should wherever possible be treated or corrected before operation, and potentially dangerous physiological disturbances avoided during and after anaesthesia.
5. Anaesthetic drugs are relatively non-toxic but there are some important effects. Halothane is occasionally associated with hepatitis and methoxyflurane with kidney damage. Malignant hyperpyrexia, the aetiology of which is uncertain, is a rare but often fatal condition which can be triggered off by several anaesthetic drugs in genetically susceptible individuals.
6. Drugs used in anaesthesia can be involved in significant unwanted interactions with other drugs.
7. The treatment of respiratory failure is usually the responsibility of the anaesthetist. Although ventilatory assistance, physiotherapy, etc. are often the mainstay of treatment, drugs of different pharmacological classes are used.
8. Pain perception is an individual sensation. Symptomatic treatment of acute pain should not therefore be based on a concept of the painfulness of certain conditions, although some anal­gesics may be more appropriate for pain of certain conditions.
9. Strong analgesics for severe chronic pain should preferably be given orally, in adequate dosage, and on a regular individualised dosage schedule.

General Considerations

Although achieving insensibility to pain and to unpleasant surroundings has been the goal of much human activity since prehistoric times, it is only since 1846 with the introduction of ether by Morton that this could be done with any re­liable chance of success. Anaesthesia has devel­oped and been refined considerably since that time, and several important milestones are re­cognized and worthy of recall. These include the discovery of the local anaesthetic action of co­caine by Koller in 1884 and its use to produce spinal anaesthesia by Bier in 1898, the perfec­tion of endotracheal anaesthesia by Magill and Rowbotham about 1920, the introduction of the first barbiturate for induction of anaesthesia in 1932, and the introduction of curare in 1942.
In recent years, the specialty of anaesthesia has been broadened, and its scope is well de­scribed in a definition for the US Department of Labor (Dripps 1966):

Anesthesiology is a practice of medicine dealing with:

• The management of procedures for ren­dering a patient insensible to pain during surgical procedures.
• The support of life functions under the stress of anesthetic and surgical manipu­lations.
• The clinical management of the patient unconscious from whatever cause.
• The management of problems in pain re­lief.
• The management of problems in cardiac and respiratory resuscitation.
• The application of specific methods of inhalational therapy.
• The clinical management of various fluid electrolyte and metabolic disturbances.

The modern concept is one of ‘balanced an­aesthesia’, in which the whole of the patient’s psyche and pathophysiology are taken into ac­count and drugs are used to modify and control any aspect as required. Thus, as well as general anaesthetic agents, drugs of many classes – tran­quillisers, analgesics, muscle relaxants, drugs af­fecting the autonomic system etc. – all fall within the sphere of interest of the anaesthetist. ( Some of the more important of these will be discussed further at later part – Drugs Used in Anaesthesia .)

General Information of the drug

• Miglitol works differently from other oral antidiabetes drugs, which control blood sugar levels by increasing the production of insulin or helping the body to use the hormone more efficiently.
• Miglitol delays the digestion of carbohydrates (sugars) by acting in the cells that line the small intestine, where sugar is absorbed. This results in less sugar being absorbed into the blood and therefore, a lower blood-sugar level.
• Miglitol also has some effect against the enzyme lactase, but usually does not cause lactose intolerance. Hypoglycemia (very low blood sugar) is unlikely with miglitol because of the way the drug works in diabetes.
• Miglitol may be prescribed with another antidiabetic drug if single-drug therapy is not enough to adequately control blood sugar levels.



• People taking miglitol should have their blood sugar checked periodically to see how well the drug is working. Your blood glucose should be carefully monitored if you add or withdraw any of these drugs while taking miglitol or acarbose. It is common for patients to equip themselves with Home Glucose Monitors, which is widely available.
• Thiazides and other diuretics, corticosteroid anti-inflammatory drugs, phenothiazines, thyroid drugs, estrogens, contraceptive drugs, phenytoin, nicotinic acid, stimulants, calcium channel blockers, and isoniazid may increase blood sugar levels.
• Miglitol and acarbose add to the blood-sugar-lowering effect of sulfonylureas, insulin, and other antidiabetes drugs and may increase the risk of hypoglycemia (low blood sugar) associated with these drugs.
• Miglitol may interfere with the absorption of several drugs into the blood, including propranolol, ranitidine, digoxin, glyburide, and metformin. Seek advise with your doctor as he/she may need to adjust your dose of these drugs.
• Digestive enzyme preparations, charcoal, kaolin (an ingredient in Kaopectate), and antacids—as well as other drugs intended to absorb stomach contents—reduce the effects of miglitol and acarbose. Separate dosing of these drugs by at least 2 hours.
• Combining acarbose and digoxin may increase the effects of digoxin.
• As Miglitol prevents the breakdown of table sugar, if you take Miglitol in combination with insulin or a sulfonylurea prescription drugs, make sure to have a quick source of glucose (dextrose) with you to treat hypoglycemia ( symptoms include increased hunger, tiredness, sweating, increased heart rate, and numbness in the arms and legs ).
• Take your dose with the first bite of each meal. The drug has to be present in your intestine to prevent the absorption of sugar into your blood.
• As Miglitol cannot work unless there is food in your stomach, if you do forget to take a dose of miglitol with your meal, skip the dose you forgot. At the beginning of your next meal, continue with your regular dose .
• Before buying any nonprescription drug, seek advice with your pharmacist to be sure if it is safe for diabetics to take together with acarbose.

Cautions

• Do not take miglitol if you are sensitive or allergic to any of its ingredients
• If you have diabetic ketoacidosis, cirrhosis of the liver, inflammatory bowel disease, ulcers in the colon, intestinal obstruction, absorption or digestion diseases, or if intestinal gas, it will be a severe problem. Consult your doctor before taking this prescription.
• Acarbose may lead to liver inflammation.
• People with kidney disease retain higher levels of miglitol in the blood, but this does not affect the drug’s action because it acts locally in cells lining the small intestine. For patients with severe kidney disease should not take this drug due to drug retention in the blood.

Dosage and Possible Overdose ( This Prescription is not for Child )

• Acarbose :- Adult: 25-100 mg with breakfast, lunch, and dinner.
• Miglitol :- Adult: 25-100 mg with breakfast, lunch, and dinner.
• Miglitol must be taken with the first bite of each main meal.
• Unlike other antidiabetic medicines, a miglitol overdose does not cause hypoglycemia. Overdose symptoms are likely to include gas, diarrhea, and pain.
• Follow your doctor’s instructions especially for dietary plan, exercise, and blood- sugar testing. ( See Possible Side Effects below )

Possible Side Effects
a. Acarbose
Intestinal side effects of acarbose tend to improve or go away after a few weeks.
Most common:

• stomach gas (in 75% of people who take it),
• abdominal pain,
• and diarrhea.

( These side effects may be worse if you don’t restrict the amount of carbohydrate in your diet. Consult your doctor on proper dietary plan )

Less common or Rarely Occurs :

• skin rashes.
• swelling and itching,
• hepatitis or yellowing of the skin or whites of the eyes,
• abdominal distress,
• abdominal obstruction,
• liver irritation,
• abnormalities in blood tests.

b. Miglitol ( Most side effects of miglitol go away with continued use of the drug )
Most common:  gas, diarrhea, and abdominal pain.
Less common or Rare Effects : rash and low blood iron.

** For Unusual Side Effects that you may notice, seek your doctor advise immediately !

Pregnancy/Breast-feeding period :
Nursing Mothers who must take this drug should use infant formula, as the safety of using miglitol during pregnancy is not known, but small amounts of miglitol pass into breast milk. ( Diabetes during pregnancy is usually treated with insulin. )

Seniors Adult Consumption
Seniors with severe kidney disease should avoid this medication.

*Blood levels of acarbose are higher in older adults, but this is usually not considered important. Always consult your doctor if in doubt.

General Information of the drug

• Clorazepate dipotassium is a benzodiazepine, which directly affect the brain. This drug is a central-nervous-system depressant, and can relax you and make you more tranquil or sleepier, or they can slow nervous system transmissions in such a way as to act as an anticonvulsant.
• Many doctors prefer benzodiazepines to other drugs that can be used to similar effect because they tend to be safer, have fewer side effects.
• Clorazepate may increase blood levels of digoxin and the chances of digoxin toxicity.
• Don’t mix it with alcohol, other sedatives, narcotics, barbiturates, monoamine oxidase inhibitor and other antidepressants, and antihistamines.
• Taking clorazepate with other similar effects drugs may result in excessive depression, tiredness, sleepiness, breathing difficulties, or related symptoms.
• Combining clorazepate with phenytoin may increase phenytoin blood concentrations and the chances of phenytoin toxicity.
• Smoking may reduce clorazepate’s effectiveness by increasing the rate at which it is broken down by the body.
• Clorazepate’s effects may be prolonged when it is mixed with cimetidine, contraceptive drugs, disulfiram, fluoxetine, isoniazid, ketoconazole, metoprolol, probenecid, propoxyphene, propranolol, rifampin, or valproic acid.
• If you have to take Tranxene for a prolong period of time, your doctor will need to monitor your blood counts and liver function to be sure of your health state.
• Theophylline may reduce clorazepate’s sedative effects.
• If you take antacids, separate them from your clorazepate dose by at least 1 hour to prevent them from interfering with the absorption of clorazepate into the bloodstream.
• The effect of levodopa + carbidopa may be decreased if it is taken together with clorazepate.

Cautions ( This drug may be addictive ! )

• Clorazepate may be addictive. It should be used with caution in people with a history of drug dependence.
• Do not take clorazepate if you are allergic or sensitive to any of its ingredients or to another benzodiazepine drug, including clonazepam.
• Clorazepate can aggravate narrow-angle glaucoma, but you may take it if you have open-angle glaucoma and are receiving therapy for it.
• Clorazepate should not be taken by psychotic patients because it is not effective for them and can trigger unusual excitement, stimulation, and rage.
• Clorazepate is not intended to be used for more than 3-4 months at a time. Your doctor should reassess your condition before continuing your prescription beyond that time.
• Your dosage should always be reduced gradually to prevent drug withdrawal symptoms, which may develop if you stop taking it after as few as 4 weeks of regular use but is more likely after longer use.
• Drug withdrawal symptoms may start with anxiety and progress to tingling in the hands or feet, sensitivity to bright light, sleep disturbances, cramps, tremors, muscle tension or twitching, poor concentration, flu-like symptoms, fatigue, appetite loss, sweating. and changes in mental state.
• Other conditions in which clorazepate should be avoided are: severe depression, severe lung disease, sleep apnea (intermittent cessation of breathing during sleep), liver disease, drunkenness, and kidney disease. In each of these conditions, the depressive effects of clorazepate may be enhanced or could be detrimental to your overall condition.

Note

• This drug is for Adult Only ! It is not recommended for child.
• Clorazepate is best taken on an empty stomach, but if it upsets your stomach then it may be taken with food. Consult your doctor on this.
• Clorazepate can cause tiredness, drowsiness, inability to concentrate, or similar symptoms. Be careful if you are driving, operating machinery, or performing other activities that require concentration.
• People taking clorazepate for more than 3 or 4 months at a time may develop drug withdrawal reactions if the medication is stopped suddenly (see “Cautions” section above). Do not stop taking clorazepate or increase or decrease your dosage without first consulting your doctor.
• Do not take a double dose. If you forget a dose of clorazepate, take it as soon as you remember. If it is almost time for your next dose, skip the dose you forgot and continue with your regular schedule.

Pregnancy/Breast-feeding period :

• Clorazepate may cause birth defects if taken during the first 3 months of pregnancy.
• Avoid this drug if you are or might be pregnant, as Clorazepate may pass into breast milk. Nursing mothers who must take clorazepate should switch to use infant formula.

1. Specific antidotal therapy is available for very few poisons. The mainstay of treatment of severe poisoning is intensive supportive therapy and good nursing care.

2. The great majority of poisoned patients recover with intensive supportive therapy alone, and enthusiastic claims for the success of other treatment often cannot be justified.

3. With some important exceptions, the management of poisoning is not altered by knowledge of plasma drug concentrations. There are many pitfalls in the interpretation of drug concen­trations in poisoned patients, especially when nonspecific analytical methods are used.

4. Gastric lavage and induction of nemesis soon after ingestion may be effective in removing unabsorbed drug, but are unreliable. Adsorbents such as activated charcoal are usually ineffec­tive in limiting absorption when given more than 1 hour after ingestion.

5. Poisoned patients are often subjected to unnecessary and potentially harmful haemodialysis, haemoperfusion and diuresis. The efficacy of these measures has been established for relatively few substances in terms of reduction in morbidity and mortality or removal of toxicologically significant amounts of active drug or poison.

6. The efficacy of methods for extracorporeal removal can be predicted from pharmacokinetic principles. It depends primarily on the volume of drug distribution, plasma protein binding, rate of transfer from peripheral to central compartments, and dialysis clearance relative to the endogenous total body clearance.

7. Haemoperfusion with activated charcoal or exchange resins is more effective than haemo­dialysis in removing drugs from the blood. Peritoneal dialysis is less effective than haemodi­alysis. Drugs with large volumes of distribution cannot be removed rapidly by any of these techniques, and indications for their use are limited.

8. Forced diuresis can only increase the renal clearance of reabsorbed compounds, and clearance may be dramatically increased by appropriate manipulation of urine pH. However, the renal excretion of most drugs is insignificant in relation to the metabolic clearance. Forced alkaline diuresis is largely restricted to salicylate and phenobarbitone poisoning.

9. Repeated oral activated charcoal effectively increases the body clearance of a number of drugs. It probably acts by irreversibly binding drug diffusing from the circulation to the gut lumen and may also interrupt the enterohepatic circulation.

10. The toxicity of a few drugs and poisons can be reversed by specific antidotal therapy. Mechanisms include pharmacological antagonism, inhibition of conversion to toxic metabolites, inactivation of highly reactive alkylating intermediates, chelation and binding with drug-specific antibodies.

This is because, unlike say sodium or glucose, the in­take of a drug is quite well known and the pro­cesses of distribution and elimination are usu­ally very simple and not under the control of a multitude of homeostatic controlling reflexes.

Given an accurate dosing history and one or more drug concentrations, it is possible to de­scribe the pharmacokinetic processes of distri­bution and elimination quite precisely in an individual patient and to make accurate predic­tions of concentrations at future points in time, whatever dosing regimen is used.

The ability to interpret drug concentrations and extract infor­mation so that future concentrations can be pre­dicted and a rational dosing scheme instituted, requires a different kind of intellectual effort from that needed to interpret, say, a serum glu­cose concentration. The latter is mostly inter­preted by reference to a so-called ‘normal range’ – usually the 95% confidence interval based upon measurements from a sample of a ‘normal’ population.

Under most circumstances, if the serum glucose concentration is within the “nor­mal range”, little further attention is paid to it If it is outside of the ‘normal range’, diagnostic efforts are made to determine what pathophys­iological process is disturbed. But the precise value will be used only in a semi quantitative fashion, eg. high, very high, or extremely high, or in reference to some previously defined diag­nostic threshold value; for example, diabetes mellitus may be diagnosed if the glucose con­centration is greater than 10 mmol/L.

On the other hand, all drug concentrations exceed the “normal” range because it would be abnormal to be able to detect any therapeutic substance in the serum of a normal, healthy individual.

The quantitative information provided by a drug concentration measurement can be use­fully applied with up to 2 significant figures in the determination of, say, drug clearance. This degree of precision is implicit in use of this in­formation because individual dosage decisions will often be made with 2 significant figures in the dose size.

The quantitative approach to therapeutic decision making is relatively new to the art of medicine. Most clinicians currently practicing medicine will not have been taught very much pharmacokinetics during their undergraduate training and may therefore have only a very hazy idea of the quantitative decisions that form the basis of rational therapeutics.

Furthermore, younger clinicians may be misled into thinking that the pharmacokinetics they were taught at medical school are irrelevant to modern medi­cine because their senior colleagues pay no at­tention to pharmacokinetic detail and make therapeutic decisions in a seemingly capricious fashion. Such a conclusion may be quite false because therapeutic decisions made by an ex­perienced clinician are founded upon a wide base of knowledge gained from treating many similar patients.

This prior knowledge of the character­istics of the population being treated provides an empirical, but nevertheless frequently satis­factory, guide to making an appropriate quan­titative and qualitative therapeutic decision. Recognition of the value of such prior infor­mation when faced with an individual patient about whom little is known is the basis of the latest techniques of rational, quantitative phar­macokinetic and pharmacodynamic forecasting.

For the person who must make a therapeutic choice on behalf of an individual patient, the application of quantitative pharmacokinetic principles can substitute for the advice of a more experienced colleague. For all clinicians, young and old, these same principles can be applied to new therapeutic entities and reduce the suf­fering of patients who would otherwise be ex­posed to the vagaries of a trial and error ap­proach.

General Information

• Amiodarone works by decreasing the sensitivity of heart tissue to nervous impulses within the heart. It should be prescribed only in situations where the abnormal rhythm is so severe as to be life-threatening and does not respond to other drug treatments.
• It has not been proven that people taking this drug will live longer than those with similar conditions who do not take it.
• Amiodarone may exert its effects 2-5 days after you start taking it, but often takes 1-3 weeks to affect your heart.
• Amiodarone’s antiarrhythmic effects can last for weeks or months after you stop taking it.

How does the drug Interact ?

• Amiodarone increases the effects of metoprolol and other beta blockers, calcium channel blockers such as verapamil and dittiazem, cyclosporine, dextromethorphan, digoxin, disopyramide, flecainide, fentanyl, lidocaine, methotrexate, procainamide, quinidine, theophylline, and warfarin and other anticoagulants. These interactions can take from 2 or 3 days to several weeks to develop. Some can be life threatening, and for others, drug dosage adjustments may be enough to avoid a serious problem.
• Fluoroquinolones, azole antifungals, and macrolide antibiotics increase the effects of amiodarone. which can cause life-threatening abnormal heart rhythms.
• When amiodarone and phenytoin are taken together, both drugs can be affected. Amiodarone can be antagonized by phenytoin and other hydantoin anticonvulsants, and the effect of phenytoin can be increased by amiodarone.
• Cholestyramine interferes with the absorption of amiodarone into the bloodstream.
• Cimetidine and ritonavir interfere with the breakdown of amiodarone, leading to high drug blood levels and the increased possibility of side effects.
• Azithromycin can interfere with the effectiveness of amiodarone. This interaction may lead to dizziness and cardiac instability.

Cautions ( This drug has fatal effects ! )

• Amiodarone can cause potentially fatal drug side effects too ! At high doses, 10% or more of people taking this drug can develop potentially fatal lung and respiratory effects, beginning with cough and progressive breathing difficulties.
• Do not take amiodarone if you are allergic or sensitive to any of its ingredients or if you have heart block or a very slow heart rate.
• Amiodarone can also cause heart block, a drastic slowing of electrical impulse movement between major areas of the heart, or extreme slowing of the heart rate. Amiodarone heart block occurs about as often as heart block caused by some other antiarrhythmic drugs, but its effects may last longer than those of the other drugs.
• Amiodarone can also worsen existing abnormal heart rhythms in 2-5% of people who take the drug. These effects can be fatal.
• Liver damage caused by amiodarone is usually mild. In rare cases. amiodarone has been associated with liver failure that resulted in death.
• People taking amiodarone may develop optic nerve irritation, leading to partial or complete loss of vision. Most adults who take amiodarone for 6 months or more develop tiny deposits in the corneas of their eyes. These deposits may cause blurred vision or halos in up to 10% of people taking amiodarone. Some people develop dry eyes and sensitivity to bright light.
• One in ten people taking amiodarone can experience unusual sensitivity to the effects of the sun. Use an appropriate sunscreen product and reapply it frequently.
• Amiodarone can cause thyroid abnormalities. It may worsen an already sluggish thyroid gland in 2-10% of people taking the drug, and increase thyroid activity in 2% of people taking it.
• Amiodarone has also been associated with an increase in risk of thyroid tumors.
• Antiarrhythmic drugs are less effective and cause abnormal rhythms if blood potassium is low.

Other Possible Side Effects

• Side effects are very common with amiodarone. About 75% of people taking 400 mg or more of amiodarone a day develop some drug side effects. As many as 18% have to stop taking the drug because of a side effect.
• Amiodarone stays in the body for months, so side effects may remain even after the drug is stopped.
• Unusual sun sensitivity is the most common skin reaction to amiodarone, but people taking this drug can develop a blue skin discoloration that may not go away completely when the drug is stopped.
• Other skin reactions are sun rashes, hair loss, and black-and-blue spots.
• Amiodarone can cause heart failure, reduced heart rate, and abnormal rhythms.
• Up to 9% of people taking amiodarone develop abnormalities in liver function

See your doctor for an eye exam if your vision changes at all while taking amiodarone.

Call your doctor if you develop chest pain. breathing difficulties, spitting up blood, nausea, vomiting, abnormal heartbeat, bloating in your feet or legs. tremors, fever, chills, sore throat, unusual bleeding or bruising, changes in skin color, unusual sunburn, or any other unusual side effect.

Note

• Amiodarone can make you dizzy or lightheaded. Take care while driving a car or performing complex tasks.
• If you take amiodarone once a day and forget to take a dose, but remember within 12 hours, take it as soon as possible.
• If you do not remember until later, skip the dose you forgot and continue with your regular schedule.
• If you take amiodarone twice a day and remember within 6 hours of your regular dose, take it as soon as you remember.
• Call your doctor if you forget to take 2 or more doses in a row, ask for doctor advise on what to do next – Do not take a double dose.
• Pregnancy and/or Breast-feeding : In high doses, amiodarone has been found to be toxic to animal fetuses. Women of childbearing age should use an effective contraceptive while taking amiodarone. If you are or might be pregnant and this drug is considered crucial by your doctor, its potential benefits must be weighed against its risks.
  Amiodarone passes into breast milk. Nursing mothers who must take this drug should use infant formula.
• Seniors : Dosage reduction may be needed in seniors with poor liver function.

Usual Dose ( Doctor Instruction Should Be followed Closely )

• Starting dose 800-1600 mg a day, taken in 1 or 2 doses, usually for 1-3 weeks. Then, 600-800 mg a day for approximately a month. Maintenance dose 400 mg a day.
• You should take the lowest effective dose in order to minimize side effects.
• Amiodarone should be taken on an empty stomach, as food delays its absorption into your bloodstream.
• If amiodarone upsets your stomach, however, you may take it with food but then always take it with food to be consistent.
• Do not drink grapefruit juice during treatment with amiodarone because grapefruit juice affects how amiodarone is absorbed in the stomach.

Over Dosage Effect(s)

• The effects of amiodarone overdose include low blood pressure. shock, slow heartbeat, and liver toxicity.
• Overdose victims should be taken to a hospital emergency room for treatment.
• ALWAYS bring the prescription bottle or container.
