Top best answers to the question «Mechanism of drug action»

In medicine, a term used to describe how a drug or other substance produces an effect in the body. For example, a drug's mechanism of action could be how it affects a specific target in a cell, such as an enzyme, or a cell function, such as cell growth.

FAQ

Those who are looking for an answer to the question «Mechanism of drug action?» often ask the following questions:

❔ Flagyl drug action mechanism?

Mechanism of Action . Metronidazole, a nitroimidazole, exerts antibacterial effects in an anaerobic environment against most obligate anaerobes. Once metronidazole enters the organism by passive diffusion and activated in the cytoplasm of susceptible anaerobic bacteria, it is reduced;

❔ Lipitor drug action mechanism?

LIPITOR (atorvastatin calcium) is a synthetic lipid-lowering agent. It is a selective, competitive inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. This enzyme catalyzes the conversion of HMG-CoA to mevalonate, which is an early and rate-limiting step in the biosynthesis of cholesterol.

❔ Molecular mechanism of drug action?

The molecular mechanism of action (MMoA) of a medicine is the connection of the molecular interactions between the therapeutic treatment and the biological target (e.g., receptor, enzyme, etc.) that yields the physiological response.

• Based on the drug target sites, the mechanisms of drug action can be classified broadly as, – Receptor mediated mechanisms – Non-receptor mediated mechanisms 4. RECEPTOR MEDIATED MECHANISM • Receptor: It is a membrane bound or intracellular macromolecular protein which is capable of binding the specific functional groups of the drug or endogenous substance.

Majority of drugs produce their effects by interacting with a discrete target biomolecule, which usually is a protein. Such mechanism confers selectivity of action to the drug. Functional proteins that are targets of drug action can be grouped into four major categories, viz. enzymes, ion channels, transporters and receptors (See Fig. 4.1).

Most drugs act by altering the various body control systems, which may be receptors, enzymes or ion channels. These various mechanisms include: 1. Physical mechanisms. 2. Chemical mechanisms. 3. Drug- receptor interactions. 4. Drug- enzyme interactions. 5. Drug- channel interactions. 6. Miscellaneous mechanisms

Mechanisms of drug action involve every aspect of a drug's fate An often under-appreciated facet of a drug’s mechanism of action is its “pharmacokinetics” “Pharmacokinetics” (how/how much gets to the target) and “pharmacodynamics” (what it does at the target) are the foundations of drug action

Mechanism of action. Morphine-6-glucuronide is responsible for approximately 85% of the response observed by morphine administration. 4 Morphine and its metabolites act as agonists of the mu and kappa opioid receptors. 1 The mu-opioid receptor is integral to morphine's effects on the ventral tegmental area of the brain.

Mechanism of action Propranolol is a nonselective β-adrenergic receptor antagonist. 2 Blocking of these receptors leads to vasoconstriction, inhibition of angiogenic factors like vascular endothelial growth factor (VEGF) and basic growth factor of fibroblasts (bFGF), induction of apoptosis of endothelial cells, as well as down regulation of the renin-angiotensin-aldosterone system. 2

Cancer cells tend to form new cells more quickly than normal cells and this makes them a better target for chemotherapy drugs. However, chemo drugs can’t tell the difference between healthy cells and cancer cells. This means normal cells are damaged along with the cancer cells, and this causes side effects.
