3 Commonly Used Medications in the Rehabilitation Patient I. TRAUMATIC BRAIN INJURY (TBI) is broadly defined as an injury resulting from external trauma and includes many different types of head trauma. These injuries often result in significant impairment of one s physical, cognitive, and psychosocial functioning. The pharmacological management of these patients involves using various medications adapted to treat the individual s specific symptoms and needs. Pharmacological agents may be useful in a variety of affective and behavioral disturbances associated with TBI and these agents are typically used for their direct and indirect pharmacological properties. There are numerous indications for some of the drug agents listed below, however the indications listed in the chart below are the most common indications seen in this patient population. TBI medications Methylphenidate (Ritalin, Concerta) Amantadine (Symmetrel) Bromocriptine (Parlodel) Donepezil (Aricept) Modafinil (Provigil) CNS Stimulant Anti-Parkinson s Agent; Antiviral; Dopamine Agonist Anti-Parkinson s Agent; Dopamine Agonist Acetylcholinester ase Inhibitor; Cholinergic Agent CNS stimulant (Nonamphetamine) Arousal, Attention, Responsiveness, Function, Motor recovery, Aphasia Function, Arousal, Responsiveness, Agitation, Emotional lability Arousal, Attention, Responsiveness, Function, Motor recovery, Aphasia, Autonomic storming Memory, Responsiveness Arousal, Attention, Responsiveness, Function 2.5mg to 20mg per dose given twice daily at 8:00 and noon 50mg to 100mg per dose once or twice daily at 8:00 and noon 2.5mg to 15mg per dose given twice daily at 8:00 and noon 5mg/day at bedtime titrated to 10mg/day at bedtime mg once daily at 8 am Common Side insomnia, decreased appetite, agitation, nausea insomnia, agitation constipation diarrhea nervousness heart rate, CBC-(with prolonged therapy) renal function, mental status, hepatic function, behavior, mood, bowel function blood pressure; levels of sleepiness Page 3 of 13

5 II. STROKE occurs when there is an acute loss in circulation to an area of the brain that results in ischemia and a corresponding loss of neurological function. Various pharmacological agents are used in the management of patients following a stroke in order to treat the associated comorbidities, as well as for secondary prevention. The medications used for stroke patients are the same as those used in traumatic brain injury patients except Propranolol (Inderal) is not used often, Phenytoin (Dilantin) is generally used in place of Carbamazepine (Tegretol, Carbitrol), and ACE inhibitors are often used. The chart below summarizes these additional medications. Stroke Medications Phenytoin (Dilantin) Trandolapril (Mavik) Lisinopril (Prinvil, Zestril) Tizanidine (Zanaflex) Enoxaparin (Lovenox) Gabapentin (Neurontin) Anticonvulsant Angiotensin- Converting Enzyme (ACE) Inhibitor Angiotensin- Converting Enzyme (ACE) Inhibitor Alpha2- Adrenergic Agonist Anticoagulant; Low Molecular Weight Heparin (LMWH) Anticonvulsant Seizure Management Hypertension Hypertension Spasticity Anticoagulant for: prophylaxis; treatment; PE treatment Neuropathic 15-20mg/kg based on serum concentrations and recent dosing history 1-4mg/day once daily 10-40mg/day 2-8mg 3 to 4 times daily Prophylaxis: 30mg SQ BID Or 40mg SQ daily (often needs to be corrected for renal impairment) Treatment: 1mg/kg/dose every 12 hours 300mg/day to 3600mg/day in 3-4 divided doses Page 5 of 13 Common Side pruritus, gingival hyperplasia, headache cough cough dry mouth, fever, confusion, pain at the injection site, bruising, bleeding, hemorrhage ataxia, fatigue plasma phenytoin level, blood pressure, CBC, liver function tests serum potassium, renal function, serum creatinine, BUN serum potassium, renal function, serum creatinine, BUN ophthalmic function, liver function platelets, occult blood, signs and symptoms of bleeding, plasma anti-factor Xa (in patients with significant renal impairment) pain assessments

6 III. SPINAL CORD INJURIES often result in neurological deficits and disability, with specific symptoms varying depending on the location of the injury. Patients with this type of injury are also at a high risk for certain types of morbidity including: thromboembolic disease, autonomic dysfunction, neuropathic pain, neurogenic bladder dysfunction, neurogenic bowel management, pressure ulceration, and spasticity. Various pharmacologic agents are used in the treatment of the morbidities seen in this patient population.

8 IV. ORTHOPEDIC/ONCOLOGY Orthopedic patients are often admitted due to fractures, most commonly of the knee and hip, and are treated with pharmacologic agents based on their condition. Most often, these patients will need pain management and thromboembolism prevention. Oncology patients are often admitted due to a decline in functional status due to disease progression or chemotherapy. Various pharmacological agents are used in managing the associated symptoms in this patient population. The medications used for these patients are similar to all previous listed medications but also include the pain management medications summarized in the chart below. Orthopedic/Oncology Medications Oxycodone (Oxycontin) Morphine (MS Contin) Tramadol (Ultram) Oxycodone/ Acetaminophen (Percocet) Opioid Opioid Non-Opioid Opioid Chronic (Moderate to Severe) Chronic (Moderate to Severe) (Moderate to Severe) (Moderate to Severe) Oral: mg every 12 hours Oral: 15-30mg every 8-12 hours mg every 4-6 hours (not to exceed 400mg/day) Based on Oxycodone content: 5-30mg every 4 to 6 hours titrated to appropriate analgesic effect (MAX Acetaminophen dose= 4g/day) Common Side pruritus, vomiting bradycardia, drowsiness, pruritus, dry mouth, weakness flushing, insomnia, tremor, seizure, pruritus, weakness pruritus, respiratory depression, sedation pain relief, respiratory status, mental status, blood pressure pain relief, respiratory status, mental status, blood pressure pain relief, respiratory rate, pulse pain relief, respiratory status, mental status, constipation Page 8 of 13

9 V. PEDIATRICS Many of the same drugs used for traumatic brain injury and spinal cord injury are also used in pediatric patients. The following are additional drugs that are used in the pediatric patient population, for the indications listed in the chart. Pediatric Medications Divalproex (Depakote) Desipramine (Norpramin) Hydrocodone/ Acetaminophen (Lortab) Anticonvulsant Antidepressant (Tricyclic) Opioid Combination Irritability Arousal, Attention (Moderate to Severe) 10-60mg/kg/day in 2-3 divided doses 1-3 mg/kg/day in divided doses Based on Hydrocodone Content: mg every 4 to 6 hours titrated to appropriate analgesic effect (MAX Acetaminophen = 4grams/day) Common Side drowsiness, dizziness loss of appetite, dry mouth, blurred vision pruritus, vomiting liver enzymes, bilirubin, serum ammonia, CBC heart rate, mental status, weight pain relief, respiratory status, mental status, blood pressure Diazepam (Valium) Lidocaine (Lidoderm) Antianxiety, Anticonvulsant, Benzodiazepine, Hypnotic, Sedative Topical Spasticity Oral: mg/kg/day in divided doses every 6-8 hours IM/IV: mg/kg/dose every 2-4 hours to a maximum of 0.6 mg/kg within an 8- hour period if needed Apply patch topically to painful area for up to 12 hours; up to 3 patches per application (Max dose 3mg/kg/dose) bradycardia, drowsiness, confusion, fatigue, blurred vision, decrease in respiratory rate skin irritation, decreased sensation heart rate, respiratory rate, blood pressure pain assessments Page 9 of 13

11 JOB AID The pharmacologic management of the TBI, stroke, SCI, Ortho patients involves using medications adapted to treat the individuals specific symptoms Pharmacologic agents have multiple uses and can be used in varying doses according to diagnosis Medications such as Coumadin or Lovenox are often used as a prophylactic to prevent the complication of s Many drugs used for pediatric patients can be the same used for the adult patient however different dose requirements must be noted. Sleep medications or seizure medications may cause the patient to be very lethargic during the day, if this does not resolve the MD should be notified- a dosage change may be warranted. Complaints of dry mouth while taking Ditropan are common, fluids should be encouraged. References Drug facts and comparisons. Lexi-Comp online. Micromedex online.
