Basics of Oral Anti-diabetic drugs

The sulfonylureas and meglitinides increase the secretion of insulin by the pancreas. _ Metformin inhibits glucose production by the liver and decreases insulin resistance. _ The alpha-glucosidase inhibitors delay absorption of glucose by the intestine. _ The thiazolidinediones decrease insulin resistance. _ The dipeptidyl peptidase 4 inhibitors promote the release of insulin from the pancreas after eating a meal. It is  necessary  to know before starting these drugs that  all the diabetes drugs have the potential to cause side effects and lifestyle changes have benefits to your health beyond controlling blood sugar, most doctors will recommend you try diet and lifestyle modifications first — before you try a drug.

EFFECT OF ACETAMINOPHEN ON BLOOD PRESSURE

Acetaminophen produces its analgesic effect by inhibiting the same cyclooxygenase, prostaglandin H2 synthase, that is the target of NSAID and aspirin. However, acetaminophen blocks this enzyme at its peroxidase catalytic rather than at the cyclooxygenase catalytic site. Therefore, the acetaminophen-mediated inhibition is sensitive to changes in the tissue peroxide levels; higher concentrations of peroxide in activated leukocytes and platelets block the effect of acetaminophen on inflammation and platelet thrombosis. However, acetaminophen is able to inhibit prostaglandins in the central nervous system, thus providing relief of pain and fever. Therefore, acetaminophen is not an NSAID or anti-thrombotic agent.   Subscribe to Drugs Information Center by Email

Tenecteplase versus Alteplase for Acute Ischemic Stroke

Intravenous alteplase is the only approved treatment for acute ischemic stroke. Tenecteplase, a genetically engineered mutant tissue plasminogen activator, is an alternative thrombolytic agent. Tenecteplase was associated with significantly better reperfusion and clinical outcomes than alteplase in patients with stroke who were selected on the basis of CT perfusion imaging.

“Gatifloxacin can cause severe hyperglycemia”

A 65-year-old woman with no history of diabetes, developed hyperglycemia, after taking Gatifloxacin. She was admitted to the hospital with a one day history of abdominal cramps, nausea, and vomiting. Her blood glucose was 1,121 mg/dL (normal range 70 to 100 mg/ dL). She had a history of high BP, transient ischemic attacks, hyperlipidemia and renal failure. The patient was receiving Gatifloxacin 200 mg daily for 9 days empirically for bronchitis, which was started during a prior hospitalization. After admission, she responded well to an insulin infusion combined with subcutaneous doses of regular insulin. (Ann Pharmacother. 2005; 39(7):1349–1352) Reports of hypoglycemia with other fluoroquinolones have been documented, but only Gatifloxacin is reported to cause severe hyperglycemia Subscribe to Drugs Information Center by Email
