In previous experiments conducted in rats, Steven N. Treistman, Ph.D., and colleagues at the University of Massachusetts Medical School determined that a brain cell membrane structure known as the BK channel, which is responsible for movement of calcium and potassium from inside to outside a cell, develops tolerance on exposure to alcohol, particularly in two brain regions important in alcohol's effects (the supraoptic nucleus and the striatum). (nih.gov)
In both regions, alcohol tolerance was manifested as decreased alcohol sensitivity and a reduced number of BK channels. (nih.gov)

Nevertheless, the physician who elects to use sertraline hydrochloride for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient (see DOSAGE AND ADMINISTRATION ). (prescriptiondrugs.com)
All other psychedelics, in man, have demonstrated tolerance to repeated administration. (erowid.org)
The study's purpose is to demonstrate acceptable growth and tolerance for three of its products to achieve permanent U.S. market authorization from the U.S. Food and Drug Administration (FDA) while it continues to import under the FDA's enforcement discretion policy. (mystateline.com)

It has not been established, however, that the action of such drugs in treating obesity is primarily one of appetite suppression. (nih.gov)
PSDDS wherein the drug release is controlled primarily by the delivery system, stimuli induced PSDDS in which release is controlled by the stimuli, such as the pH present in the intestinal tract. (scialert.net)

The only possible exception to this rule is in the case of drug-induced seizures, particularly with seizures secondary to theophylline ingestion, in which phenobarbital may be administered prior to phenytoin. (medscape.com)

Diethylpropion hydrochloride is a sympathomimetic amine with some pharmacologic activity similar to that of the prototype drugs of this class used in obesity, the amphetamines. (nih.gov)
1) Yet already by 1972 PIR's pharmacologic uniqueness led C.E. Giurgea, UCB's principal PIR researcher and research co-ordinator, to formulate an entirely new category of drugs to describe PIR: the nootropic drug. (worldhealth.net)

A prominent example of such compounds is Remdesivir, a broad-spectrum antiviral drug that features a phosphorus stereocentre and has gained considerable interest during the COVID-19 pandemic. (nature.com)
The flexibility of the method is demonstrated by the fact that distinct stereoisomers of chiral phosphorus compounds can be formed by simply changing the order of steps in the synthetic sequence. (nature.com)

These two latter receptors are extremely similar, and drugs that block the '2' subtype usually block the '1C' as well. (erowid.org)

Pure enantiomers are essential, for instance, as chiral ligands and for drug discovery. (nature.com)
The Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence is a fundamental tool in NMR spectroscopy, which is widely used for the suppression of protein signals for metabolomic and drug discovery applications. (dur.ac.uk)
Understanding mode of action is a key component of drug discovery and network biology approaches enable a global, integrated view of microbial physiology, including mechanisms of antibiotic killing. (st-andrews.ac.uk)

It is estimated that mortality among people who inject drugs (PWID), which are frequently opioids, is 14 times greater than that of the general population (2). (who.int)

The main groups include sodium channel blockers, calcium current inhibitors, gamma-aminobutyric acid (GABA) enhancers, glutamate blockers, carbonic anhydrase inhibitors, hormones, and drugs with unknown mechanisms of action (see the image below). (medscape.com)

We present miniaturized, microfluidic ADA immunoassays with an automated acid dissociation step that demonstrate high sensitivity, high-quality, and drug-tolerant assays. (gyrosproteintechnologies.com)

Several days drug-free are necessary to return to the previous level of sensitivity. (erowid.org)

In addition, the controlled drug delivery area needs further development of techniques for delivery of peptide and protein drugs. (scialert.net)
However, baseline PTSD symptom ratings did not change over time, and the researchers detected evidence that people used higher doses over time to manage anxiety, indicating the development of tolerance to the drug. (medpagetoday.com)
