Clinical Summary

A pyrrole and heptanoic acid derivative, HYDROXYMETHYLGLUTARYL-COA REDUCTASE INHIBITOR (statin), and ANTICHOLESTEREMIC AGENT that is used to reduce serum levels of LDL-CHOLESTEROL; APOLIPOPROTEIN B; and TRIGLYCERIDES. It is used to increase serum levels of HDL-CHOLESTEROL in the treatment of HYPERLIPIDEMIAS, and for the prevention of CARDIOVASCULAR DISEASES in patients with multiple risk factors.

Therapeutic Applications

Atorvastatin is used along with a proper diet to help lower bad cholesterol and fats (such as LDL, triglycerides) and raise good cholesterol (HDL) in the blood. It belongs to a group of drugs known as statins. It works by reducing the amount of cholesterol made by the liver. Lowering bad cholesterol and triglycerides and raising good cholesterol decreases the risk of heart disease and helps prevent strokes and heart attacks. In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking. Consult your doctor for more details.

Therapeutic Applications

Apixaban is used to prevent serious blood clots from forming due to a certain irregular heartbeat (atrial fibrillation) or after hip/knee replacement surgery. With atrial fibrillation, part of the heart does not beat the way it should. This can lead to blood clots forming, which can travel to other parts of your body (such as the lungs or legs) or increase your risk for stroke. In the United States, apixaban is also approved to treat certain types of blood clots (deep vein thrombosis-DVT, pulmonary embolus-PE) and to prevent them from forming again. Apixaban is an anticoagulant that works by blocking certain clotting proteins in your blood.

Clinical Summary

A specific opiate antagonist that has no agonist activity. It is a competitive antagonist at mu, delta, and kappa opioid receptors.

Therapeutic Applications

This medication is used for the emergency treatment of known or suspected opioid overdose. Serious opioid overdose symptoms may include unusual sleepiness, unusual difficulty waking up, or breathing problems (ranging from slow/shallow breathing to no breathing). Other symptoms of overdose may include very small pinpoint pupils, slow heartbeat, or low blood pressure. If someone has serious overdose symptoms but you are not sure if the symptoms are due to overdose, give this medication right away anyway, since lasting slow/shallow breathing may cause permanent damage to the brain or death. This medication belongs to a class of drugs known as opioid antagonists. It works by blocking the effects of the opioid in the brain. This medication may not work as well to block the effects of certain types of opioids (mixed agonist/antagonists such as buprenorphine, pentazocine). With these types of opioids, blocking may be incomplete or you may need a higher dose of naloxone. The effects of naloxone will not last as long as the effects of the opioid. Since treatment with this medication is not long lasting, be sure to get medical help right away after giving the first dose of naloxone. Treatment of opioid overdose should also include breathing treatment (such as oxygen given through tubes in the nose, mechanical ventilation, artificial respiration).

Tamsulosin belongs to a class of drugs known as alpha blockers. Do not use this medication to treat high blood pressure.
