What is the diagnosis and treatment plan for a 45-year-old woman with Type 2 Diabetes Mellitus, Dyslipidemia, and Hypertension, presenting with muscle cramps, weakness, diarrhea, and dizziness, on Metformin, Lisinopril, Bisoprolol, and Pravastatin?

From the Guidelines

Sarah Martin's bisoprolol dose should be reduced to 5-10 mg once daily to minimize potential side effects, including bradycardia, gastrointestinal disturbances, and muscle-related complaints, while maintaining reasonable blood pressure control with lisinopril. Her current medication regimen includes metformin for diabetes management, lisinopril for hypertension, and pravastatin for dyslipidemia, which appear to be appropriate for her conditions. However, the high dose of bisoprolol (16 mg twice daily) is likely contributing to her symptoms of muscle cramps, weakness, numbness in limbs, frequent diarrhea, and dizziness. The patient's blood pressure is reasonably controlled at 134/82 mmHg, and the combination of lisinopril and bisoprolol is suitable for hypertension management in a patient with diabetes, but the bisoprolol dosing needs adjustment 1. Additionally, her symptoms could represent beta-blocker side effects, and her metformin and pravastatin appear appropriate for managing her diabetes and dyslipidemia 1. The patient should be monitored for electrolyte abnormalities, particularly potassium levels, which could be affected by both lisinopril and diarrhea 1. Her symptoms should be reassessed after dose adjustment, and if they persist, further investigation for other causes would be warranted. It is also essential to consider her family history of hypertension, dyslipidemia, and diabetes, as well as her personal history of obesity and smoking cessation, when managing her conditions 1. Overall, the adjustment of bisoprolol dosing and continued monitoring of her conditions and medication side effects are crucial for optimizing her treatment plan and improving her quality of life.

5 WARNINGS AND PRECAUTIONS

5.1 Myopathy and Rhabdomyolysis Pravastatin may cause myopathy and rhabdomyolysis. Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in creatine phosphokinase (CK) to greater than 10 times the upper limit of normal (ULN), occurred <0.1% in pravastatin-treated patients in clinical trials.

The patient is experiencing muscle cramps, muscle weakness or numbness in limbs, which are symptoms that may be related to myopathy caused by pravastatin.

• Myopathy is a known side effect of pravastatin, occurring in less than 0.1% of patients in clinical trials.
• The patient should be monitored for elevated CK levels and myopathy.
• If myopathy is diagnosed or suspected, pravastatin should be discontinued.
• The patient should be instructed to promptly report any unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever 2.

From the Research

Patient Profile

• Sarah Martin, a 45-year-old woman with a history of diabetes II, dyslipidemia, and recent hypertension
• She has been experiencing muscle cramps, muscle weakness or numbness in limbs, frequent diarrhea, and dizziness
• Her current medications include metformin, lisinopril, bisoprolol, and pravastatin

Medication Adherence

• Medication adherence is crucial for the success of treatment, especially in patients with multimorbidity 3
• Non-adherence can be intentional or non-intentional and can be affected by various factors
• Interaction with a health professional is important for understanding the reason for non-adherence and promoting adherence

Muscle Cramps and Weakness

• Muscle cramps are painful, sudden, involuntary muscle contractions that can be associated with a wide range of acquired and inherited causes 4
• Statins, such as pravastatin, can cause muscle symptoms, including muscle pain and cramps, although the evidence is not always strong 5
• The patient's symptoms of muscle cramps and weakness could be related to her medication or underlying medical conditions

Self-Management Support

• Self-management support is crucial for patients with chronic conditions, and primary health professionals can play a key role in delivering this support 6
• Effective self-management support strategies include a structured patient-provider exchange, tailored interventions, and ongoing follow-up
• These strategies can improve clinical indicators, health-related quality of life, and self-efficacy in patients with chronic conditions

Treatment Approach

• The patient's treatment approach should be individualized and take into account her complex medical history and symptoms
• A collaborative approach between the patient and healthcare provider is essential for effective management of her conditions
• Regular follow-up and monitoring of her symptoms and medication adherence can help to identify any issues and adjust her treatment plan as needed
