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,

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.

• Gastric Aspiration and Lavage

Although unabsorbed drug in the stomach may be removed by gastric aspiration and lav­age its usefulness in practice has been seriously questioned (Proudfoot 1984). Most drugs and poisons seem to be absorbed rapidly and this technique is unlikely to be productive more than 4 hours after ingestion, unless gastric emptying has been delayed by opioid analgesics, anti­cholinergic agents, central nervous system de­pressants, and possibly salicylates. In such circumstances gastric lavage may be worthwhile up to 12 hours after ingestion.

It is said to be contraindicated after ingestion of corrosives and hydrocarbons such as paraffin because of the risks of perforation and lipoid pneumonia, respectively.

The patient must be correctly positioned head down in the left lateral position and a cuffed endotracheal tube inserted beforehand if the protective pharyngeal reflexes are depressed. It is essential to use a large bore tube (e.g. Jacques 30 gauge) and in adults lavage should be carried out with 300ml portions of warm tap water un­til the return is clear. Complications include pulmonary aspiration of stomach contents, and, rarely, oesophageal rupture.

Although gastric lavage is often unrewarding, large amounts of drug are occasionally re­covered. A common cause of failure is the use of too small a tube – an ordinary nasogastric tube is virtually useless. Large amounts of re­sidual drug have been found in the stomach postmortem after attempts at lavage with a nasogastric tube (Jenis et al. 1969), and in i case i large drug mass containing 25g of meproba­mate was removed by gastrotomy 40 hours after ingestion despite gastric lavage (Schwartz 1977).

Emetics

The comparative efficacy of induced emesis and gastric lavage is still debated. Neither guar­antees emptying of the stomach. Lavage is not always practicable in children because of the physical difficulty in passing a tube large enough to allow the passage of tablets, and emesis is probably preferable in young children. In 1 study in children poisoned with salicylates, emesis was claimed to be more effective than lavage (Boxer et al. 1969), but in another, only 10 to 15% of the amount of salicylate taken was recovered, even when emesis occurred within 1 hour of ingestion (Yaffe et al. 1970).

The major disadvantages are failure of eme­sis, particularly if central nervous system de­pressants have been taken, and toxicity, some­times fatal, from the retained emetic. Syrup of ipecac given with water is probably the best emetic, and is often effective within 15 to 30 minutes (Neuvonen et al. 1983).

Other agents which have been used include sodium chloride, copper sulphate, zinc sulphate, tartar emetic (antimony potassium tartrate), apomorphine and mustard. However, the over-enthusiastic use of sodium chloride and heavy metals can be ex­tremely dangerous and fatal poisoning with salt and copper sulphate has been reported (Gresham & Mashru 1982; Stein et al. 1976).

Although quinidine is rarely used for this purpose today, because of the advent of DC cardioversion, this study is still almost unique because it defined a target concentration based upon both the probability of therapeutic success and of toxicity.

A concentration of 8 rag/ L was shown to have an 80% chance of converting atrial fibrillation to sinus rhythm and a 20% chance of some serious toxicity. No atten­tion was paid to pharmacokinetics, The target concentration was chosen on the basis of pharmacodynamics, i.e. the effects, both good and bad, observed at particular concentrations.

Rational therapeutics – the aim of rational ther­apeutics is to achieve the desired effect with the cor­rect dose. The foundation of decision making is based on pharmacokinetics and pharmacodynamics which provide the rational principles to link dose and effect through drug concentration.

Rational therapeutics can be defined as the administration of the correct dose to achieve the desired effect. The target concentration concept is at the centre of rational therapeutics where it links dose to effect. Pharmacokinetics is the science that links dose and concentration by defining the processes of drug distribution (volume of distribution) and elimination (clear­ance).

Pharmacodynamics, on the other hand, is the science linking concentration to effect by defining the maximum effect of the drug (Emax) and the sensitivity of the target organ (as de­termined by the EC50; M£ the concentration producing 50% of Emax).

Therapeutic drug monitoring can now be placed at the centre of this therapeutic triangle. This incorporates information about doses, concentrations, and effects in an individ­ual and integrates these data to estimate more precisely the pharmacokinetic (volume of dis­tribution, clearance) and pharmacodynamic (Emax, EC50) parameters in that individual. These new values can then be used to predict the consequences of future dosing decisions and thus enable the selection of a suitable dose to achieve the desired effect, i.e. rational therapeutics.

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.

• 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.
