Celecoxib, sold under the brand name Celebrex among others, is a COX-2 selective In July the FDA strengthened the warning that non-aspirin NSAIDs can cause heart attacks or strokes. . Various modifications can be made to the 1,5-diarylpyrazole moiety to deduce the structure-activity relationship of celecoxib.

The reports indicate that doctors have inappropriately prescribed the fentanyl patch In addition, the reports indicate that patients are continuing to incorrectly use the fentanyl patch More than 12 different analogues of fentanyl, all unapproved and clandestinely produced, have been identified in the U. In Februarythe U. Drug Enforcement Administration indicated that illicit fentanyl analogs have no medically valid use, and thus applied a "Schedule I" classification to them.

Fentanyl is used orally, smoked, snorted, or injected.

Fentanyl is sometimes sold as heroin or oxycodonesometimes leading to overdoses. Many fentanyl overdoses are initially classified as heroin overdoses. Estonia has the highest rate of 3-methylfentanyl overdose deaths in the EU, due to its high rate of recreational use.

The gel from inside the patches is sometimes ingested or injected. Like all opioids, the effects of fentanyl can be reversed with naloxoneor other opiate antagonists. Naloxone is increasingly available to the public. Long acting or sustained release opioids may require repeat dosage. Illicitly synthesized fentanyl powder has also appeared on the United States market. Because of the extremely high strength of pure fentanyl powder, it is very difficult to dilute appropriately, and often the resulting mixture may be far too strong and, therefore, very dangerous.

Inillegally manufactured, non-pharmaceutical fentanyl often mixed with cocaine or heroin caused an outbreak of overdose deaths in the United States and Canada, heavily concentrated in the cities of Dayton, Ohio; Chicago; Detroit; and Philadelphia.

In Junegrams 2. However, in Aprilthere was one domestic fentanyl lab discovered by law enforcement in Azusa, California. They found about 70, pills in the appearance of oxycodone and more than 25, in the appearance of Xanax.

The DEA reported that millions of pills could have been distributed from this location over the course of time. The accused owned a pill press and ordered fentanyl in powder form from China. This results in a drug with an increased duration. Authorities suspect that the drug is being imported from Asia to the western coast by organized crime groups in powder form and being pressed into pseudo-OxyContin tablets.

Risk may be increased with duration of use or pre-existing cardiovascular risk factors or disease. Individual cardiovascular risk profiles should be evaluated prior to prescribing.

New-onset hypertension or exacerbation of hypertension may occur NSAIDs may impair response to thiazide or loop diureticsand may contribute to cardiovascular events; monitor blood pressure and use with caution in patients with hypertension. May cause sodium and fluid retention, use with caution in patients with edema or heart failure.

Long-term cardiovascular risk in children has not been evaluated. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of cardiovascular events; alternative therapies should be considered for patients at high risk.

These events may occur at any time during therapy and without warning. Use the lowest effective dose for the shortest duration of time, consistent with individual patient goals, to reduce risk of GI adverse events; alternate therapies should be considered for patients at high risk.

Anemia may occur; monitor hemoglobin or hematocrit in people on long-term treatment. Celecoxib does not usually affect prothrombin timepartial thromboplastin time or platelet counts; it does not inhibit platelet aggregation at approved doses.

People with prior history of ulcer disease or GI bleeding require special precaution. Allergy[ edit ] Celecoxib contains a sulfonamide moiety and may cause allergic reactions in those allergic to other sulfonamide-containing drugs.
