The sedative effects of benzodiazepine receptors are due to activation of α-1 subunits of GABA receptors. The anxiolytic activity associated with the benzodiazepine is due to α-2 subunit activity. The GABAA receptor is large, providing attachment sites for GABA, benzodiazepines, barbiturates, etomidate, propofol, and alcohol. This property explains the pharmacologic synergy of these substances and
Barbiturate withdrawal is when sudden stopping of barbiturate drugs causes severe illness and withdrawal. This especially happens when infusions are given in the hospital and abruptly stopped. What are the Barbiturate withdrawal symptoms? In the First 12-16 hours: There is an observable improvement. After 16 hours: nausea, vomiting, anxiety, tremors, abdominal cramps, orthostatic hypotension, restlessness.
The pharmacokinetics of inhaled anesthetics are explained here with detail • Absorption of agent from alveoli to blood • Distribution in the body • Metabolism (liver) • Elimination (lungs mainly) Uptake and Distribution The pharmacokinetics of inhaled anesthetics depends upon: (1) Respiratory uptake, (2) Alveolar ventilation, (3) The partial pressure of the agent in the
There are various ways of describing what is opioid. The common feature of all the drugs belonging to the group of these drugs is a phenanthrene ring with side chain and additional rings that might be added to the central ring itself or to the side chains. 1. Naturally occurring: morphine, codeine, kheline, noscapine, and thebaine. 2.
IV lasix or Furosemide is a loop diuretic that acts by inhibiting the reabsorption of sodium and chloride (via the Na/K/2Cl cotransporter) in the thick ascending limb of the loop of Henle. IV lasix enhances the excretion of sodium, potassium, calcium, chloride, and water. IV lasix is used frequently in the intensive care unit (ICU) setting
Diazepam half life could be observed during rapid absorption from the gastrointestinal tract after oral administration, reaching peak concentrations in about 1 hour in adults and within 15 to 30 minutes in children. There is rapid uptake of diazepam into the brain, followed by redistribution to inactive tissue sites. The Vd of diazepam is large,
Once Pure agent scheme of presentation is executed it becomes very easy to deal with all the actions of the drugs of various classes of opioids, including pure agonist opioid . While understanding the pharmacological, systemic effect of these drugs it is logically possible to fix the action as per the neuroanatomical site of origin
Reiki therapy techniques have been in practice since 2nd—3rd century; it was forgotten and about 130 years back was reinvented by Dr. Mikao Usui. WHO has defined it as “Non physical healing energy comprising universal life force energy (divine in nature) having its own intelligence”. Rei: means in Japanese, universal; Ki : life force energy
Naloxone (N-allyl oxomorphone) and newer drugs like nalmexone, naltrexone, nalmefene, and nalbuphine belong to naloxone group. These drugs have practically no agonist action on any of the receptors or their subtypes. But these drugs completely reverse the action of all the drugs, pure, partial, agonist-antagonists at µ, K, σ, δ and other receptors including analgesia, respiratory
Partial agonist buprenorphine is an opioid, which strikingly differs chemically from other opioids, in that it is not related to morphine, but to another alkaloid called thebaine. So buprenorphine is a semi synthetic opioid. Pharmacodynamically, partial agonist buprenorphine is highly potent. 0.3 mg is equianalgesic with 10 mg of morphine. It has a 50 times
