When using garlic, it is recommended to avoid any other drugs that may interfere with platelet and _liver__ function. These drugs include antiplatelet drugs, anticoagulants, nonsteroidal anti-inflammatory drugs, and aspirin 7. HDLs are responsible for the “recycling” of cholesterol. HDLs are sometimes referred to as the _good lipid (or good cholesterol) because they are believed to be _cardioprotective_. LDLs are known as the “bad” cholesterol. 8. The maximum extent to which lipid levels are lowered may not occur until _6_ to _8_ weeks after the start of therapy.

9. _Myopathy_ (muscle pain) is a clinically important adverse effect that may occur with the HMG-CoA reductase. It may progress to a serious condition known as rhabdomyolysis. 10. Taking HMG-CoA reductase inhibitors with __grapefruit__ juice may cause complications. Components in the juice inactivate CYP3A4 in both the liver and intestines.

To treat hypoglycemia a quick source of _glucose__ should always be kept at hand. 8. Rapid-acting insulins, such as insulin_lispro_ and insulin _aspart_, are able to mimic closely the body’s natural rapid insulin output after eating a_meal_; for this reason, both insulins are usually administered within 15 minutes of the patient beginning a meal.

9. The hemoglobin __A1C_ level reflects the patient’s adherence to the therapy regimen for previous several _years_ . 10.

Hepatic __necrosis_ is the most serious acute toxic effect of an acute overdose of acetaminophen. 8. If a patient is taking long-acting opioid analgesics, _breakthrough__ pain must be treated with an immediate- release dosage form that is given between scheduled doses of the long-acting opioid.

9. Feverfew is commonly used for _migraine_ headaches, menstrual problems, arthritis, and fever. 10. Acetylcysteine has the flavor of rotten _eggs__ and so is better tolerated if it is diluted and disguised by mixing with a drink such as cola or flavored water to help increase its palatability.

11 Anticonvulsants are often used as adjuvants for treatment of _neuropathic__ pain to enhance analgesic efficacy. 12 Constipation, lightheadedness , urinary retention, and itching are some of the common adverse effects that the patient may experience while taking _opioid__. Chapter 12 Anesthetics Review KEY Pharmacology 3342 1. Infiltration anesthesia is commonly used for minor surgical procedures. It involves injecting the local anesthetic solution _intradermally_, subcutaneously, or submucosally across the path of _nerve_ supplying the area to be anesthetized.

The local anesthetic may be administered in a circular pattern around the operative field 2. Vasoconstrictors such as _epinephrine___ are coadministered with local anesthetics to keep the anesthetic at its local site of action and to prevent systemic absorption.

3. After surgery and the termination of general anesthesia, the main concern is assessing the patient’s A_airway__, B_pain_, and C_mental_ status. 4. A sudden elevation in body temperature during the postoperative period may indicate the occurrence of _malignant hyperthermia_, a life-threatening emergency. 5.

The elderly patient is _more_ affected by anesthesia than the young or middle-aged adult patient because of the effects of aging on the hepatic, cardiac, respiratory, and renal systems. 6. Patients receiving neuromuscular blocking drugs require artificial _mechanical_ ventilation because of the resultant paralysis of the _flaccid__ muscles. In addition, they do not cause _sedation_ or pain relief.

They are used along with, not instead of, general anesthesia during surgery. 7. The antidote for neuromuscular blocking drugs is an anticholinesterase drug, such as _neostigmine / prostigmin__ that reverses the effects of neuromuscular blocking drugs.

8. Moderate sedation effectively reduces patient anxiety, sensitivity to _pain_, and _recall_ of the medical procedure, yet it preserves a patient’s ability to maintain his or her own _airway__ and respond to verbal commands. 9. Tachycardia, tachypnea, muscle __rigidity_, and raised ________________ are symptoms of malignant hyperthermia, which is treated with cardiorespiratory supportive care as needed to stabilize heart and lung function as well as with immediate treatment with the skeletal muscle relaxant _dantrolene__.
