In type 2 diabetes, your body does not work properly to store excess sugar and the sugar remains in your blood. High blood sugar over a long time can lead to serious health problems.
How does a DPP-4 inhibitor work?
DPP-4 inhibitors work by blocking the action of DPP-4, an enzyme which destroys the hormone incretin. Incretins help the body produce more insulin only when it is needed and reduce the amount of glucose being produced by the liver when it is not needed.
Is fenfluramine an SSRI?
Fenfluramine is a selective serotonin reuptake inhibitor (SSRI), which increases serotonin content in the brain’s synapses to decrease caloric intake. Anorexia and weight loss induced by fenfluramine have been demonstrated in numerous early therapeutic trials [152].
What is the mode of action of chlorpropamide?
Chlorpropamide is an oral antihyperglycemic agent used for the treatment of non-insulin-dependent diabetes mellitus (NIDDM). It belongs to the sulfonylurea class of insulin secretagogues, which act by stimulating β cells of the pancreas to release insulin.
Why is thiazolidinediones contraindicated in heart failure?
However, thiazolidinediones can cause fluid retention thereby increasing the risk of heart failure—a common complication of type 2 diabetes mellitus.
What is the absorption rate of phenformin?
Phenformin is ∼50% absorbed from the gastrointestinal tract. Its protein binding ability is very poor, which is ∼20%. Phenformin is distributed throughout the major organs and it is mainly metabolized in the liver by hydroxylation.
What is the protein binding ability of phenformin?
Its protein binding ability is very poor, which is ∼20%. Phenformin is distributed throughout the major organs and it is mainly metabolized in the liver by hydroxylation. On hydroxylation, it produces N – P -hydroxy- B -phenyl-ethyl biguanide as a metabolite.
What is the pharmacokinetics of ethanol after typical doses?
1 Department of Pharmacology and Clinical Pharmacology, School of Medicine, University of Auckland. The pharmacokinetics of ethanol after typical doses are described by a 1-compartment model with concentration-dependent elimination. The volume of distribution estimated from blood concentrations is about 37 L/70 kg.
Can phenobarbital dosing be used to treat alcohol withdrawal syndrome?
We used a pharmacokinetically derived phenobarbital dosing protocol to treat alcohol withdrawal syndrome in patients admitted to a family medicine inpatient service. We describe the protocol and include two case reports documenting its efficacy.
