Chart 3.

Points to discuss with patients and suggested recommendations

MMAS-4 question Do you ever forget to take your medicine? Do you ever have problems remembering to take your medicine? When you feel better do you sometimes stop taking your medicine? When you sometimes feel worse when you take the medicine, do you stop taking it?
Specific goal To improve memory for medication taking To adapt the regimen to the patient's daily schedule to address carelessness To avoid stopping the treatment when feeling better To avoid stopping the treatment when feeling worse
  Procedure 1 Procedure 2 Procedure 3
  Provide an easy reminder and identify a daily activity or cue that the patient does regularly at about the time he or she should take medications and explain to the patient to take medications at this time Explain fundamentals of hypertension and its management to patient in terms he or she can understand. Explain how the medication works in a simple way and what are the specific consequences or effects if the patient stops taking it. Teach patient how to monitor the most common side effects of his or her treatment (withdrawal rates due to side effects must be investigated). Support and encourage patient to report the problem to the physician.
  Therapeutic class information
Agents acting on the renin- angiotensin system, Beta blocking agents and Calcium channel blockers This medicines act by dilating the blood vessels (and, in some cases*, reducing heart muscles contractility). Therefore amlodipine and losartan may take a few weeks to show noticeable effects.
  Linking medication taking to patient's daily schedule31 Withdrawal symptoms Potential causes of withdrawal
Amlodipine Optimal dosing time: in the morning, around breakfast time (there is little evidence of what is the optimal time to take once-daily amlodipine, however the optimal dosing time may be morning). Abrupt withdrawal of this agent can precipitate coronary vasospasm, which may result in myocardial infarction. Peripheral edema, fatigue, palpitation, headache, dyspepsia, nausea.
May be taken with food.
Atenolol Optimal dosing time: uncertain. Tachycardia, palpitation, excessive sweating, chest pain, heart attack, death. Hypotension, bradycardia, bronchospasm, cold extremities.
May be taken with food (although the presence of food may reduce the bioavailability of atenolol by 20%).
Captopril Optimal dosing time: uncertain (although there is fair evidence that bedtime dosing may constitute an effective option to reduce cardiovascular risk) Abrupt withdrawal of these agents can precipitate hypertensive rebound in diabetic patients with chronic renal failure Dry cough, hyperkalemia (especially if used with spironolactone; main symptoms: palpitations and muscle weakness), postural hypotension.
May be taken without food.
Carvedilol Optimal dosing time: evening. Tachycardia, palpitation, excessive sweating, chest pain, heart attack, death. Fatigue, hypotension, diarrhea, asthenia, bradycardia, dizziness, edema.
May be taken with food.
Enalapril Optimal dosing time: evening. Abrupt withdrawal of these agents can precipitate hypertensive rebound in diabetic patients with chronic renal failure Hypotension, dry cough.
May be taken with food.
Losartan Optimal dosing time: administration time-dependent effects of losartan have not been documented. There is little evidence of rebound effect after abrupt withdrawal of losartan therapy Dizziness, diarrhea, tiredness.
May be taken with food (concurrent use of losartan and grapefruit juice may result in increased half-life and decreased area under the concentration time curve of losartan's active metabolite).
  Therapeutic class information
Diuretics These medications increase water loss by inhibiting sodium and chloride resorption in the kidneys. When taking these antihypertensives, one will urinate a lot because of the increased water loss.
  Linking medication taking to patient's daily schedule Withdrawal symptoms Potential causes of withdrawal
Hydrochlorothiazide Optimal dosing time: before 6 pm and preferably in the morning If diuretics are withdrawn suddenly in patients with a normal sodium intake, there will be rebound retention of sodium and water (with consequent edema), because compensatory mechanisms that maintain sodium balance in the face of diuretics continue to act for several days after diuresis has worn off. Hypokalemia (symptoms include muscular weakness, myalgia, and muscle cramps), weakness.
May be taken with food.
Furosemide Optimal dosing time: no significant difference related to dosing time was observed between morning and evening trials. Hypokalemia (symptoms include muscular weakness, myalgia, and muscle cramps), hyperglycemia, hyponatremia (symptoms include nausea and vomiting, headache, fatigue, appetite loss).
May be taken with food.
Spironolactone Optimal dosing time: administration time-dependent effects of spironolactone have not been documented. There is no apparent rebound effect after abrupt withdrawal of spironolactone therapy Hyperkalemia (main symptoms: palpitations and muscle weakness).
May be taken with food.
  Therapeutic class information
Platelet aggregation inhibitors Treatment with blood thinners prevents blood clots from forming in blood vessels. It may be used to prevent or treat heart attacks and stroke.
  Linking medication taking to patient's daily schedule Withdrawal symptoms Potential causes of withdrawal
Acetylsalicylic acid Optimal dosing time: in the morning and/or in the evening with food (bedtime administration of aspirin decreases morning surge of platelet aggregation while kept same antiplatelet efficacy during other time of the day compared to taking these drugs at day-time). The withdrawal of acetylsalicylic acid may be associated with traditional cardiovascular risk factors and thrombosis. Gastrointestinal side effects (pain, heartburn, indigestion), bleeding.
Clopidogrel Optimal dosing time: in the morning and/or in the evening with food (bedtime administration of clopidogrel decreases morning surge of platelet aggregation while kept same antiplatelet efficacy during other time of the day compared to taking these drugs at day-time). Clopidogrel withdrawal is associated with a rebound prothrombotic and/ or proinflammatory response. Premature cessation of clopidogrel in patients receiving drug-eluting stents is a clear risk factor for stent thrombosis. Bleeding, Gastrointestinal side effects (pain, heartburn, indigestion, diarrhea), rash.
  Therapeutic class information
Lipid modifying agent These agents are used along with a proper diet to help lower 'bad' cholesterol and fats and raise 'good' cholesterol in the blood
  Linking medication taking to patient's daily schedule Withdrawal symptoms Potential causes of withdrawal
Rosuvastatin Optimal dosing time: in the morning or in the evening (there are sufficient data to support evening administration of simvastatin to achieve optimal effect, however the elimination half-life of rosuvastatin is significantly longer and this is probably significant in the ability to take it in the morning with non-significant changes in lipid lowering compared to evening administration). Statin withdrawal abrogates this beneficial effect in patients initially responsive to this therapy and may cause rebound inflammatory effect. Muscle pain, fatigue and weakness, myalgia, cognitive loss.
May be taken without food.
