This butorphanol drug class was introduced about 25-30 years back. That was the era of morphine, pethidine, so it did not gain much acceptance. But now re-introduced, has become a major “find”. It is a classical example of “resurrection”. Butorphanol is a morphinan derivative with spectrum of activity almost like pentazocine, only that it is 20 […]
All of these nonsteroidal anti inflammatory drugs side effects collectively lead to breach of the integrity of gastric mucosal lining, and gastric ulceration is the result. Following are the nonsteroidal anti inflammatory drugs side effects : Gastritis : As an overall decrease in production of prostaglandins takes place. Some of the protective PGs like PGE1, PGE2,and

Neo-Synephrine is the trade name for phenylephrine. It is a pure alpha receptor agonist and has both venous and arterial constrictive effects. Because Alpha1 receptors have been discovered in the myocardium, it is also possible that it has positive inotropic effects. In our current culture of patient safety, it is important to avoid commonly used medical
For sedation prior to anesthesia or procedures, for longer and/or more stimulating procedures, midazolam IM can be used to facilitate insertion of an IV catheter for titration of additional medication. Midazolam IM doses of 0.1 to 0.15 mg/kg are usually effective and do not prolong emergence from general anesthesia. For more anxious patients, doses up
Anesthetic propofol is a potent intravenous hypnotic agent which is widely used for the induction and maintenance of anesthesia. Propofol is a phenolic (2, 6-diisopropylphenol) derivative that is structurally unrelated to other sedative hypnotic agents. It has been used extensively as an anesthetic propofol agent, particularly in procedures of short duration. More recently it has
Midazolam effects cerebral metabolic oxygen requirement (CMRO2) by decreasing it and cerebral blood flow, analogous to barbiturates and propofol. It causes dose-related changes in regional cerebral blood flow in brain regions associated with the normal functioning of arousal, attention, and memory. Patients with decreased intracranial compliance show little or no change in intra-cranial pressure when
Lasix is known to cause Sulfa allergy. The decrease in sodium and chloride reabsorption seems to come from the fact that furosemide competes for the chloride position on the carrier. Furosemide (Lasix) is a member of the general class of loop diuretics that inhibit the Na+/K+/2Cl–cotransport carrier within the ascending limb of the loop of
Etomidate shortens the onset time of the neuromuscular block with vecuronium. This etomidate drug interactions enhances the bradycardia induced by vecuronium. Miller’s anesthesia says the following about etomidate drug interactions – The specific endocrine effects manifested by etomidate are a dose-dependent reversible inhibition of the enzyme 11β-hydroxylase, which converts 11-deoxycortisol to cortisol, and a relatively minor
Ketamine cardiovascular effects resemble sympathetic nervous system stimulation. Indeed, a direct negative cardiac inotropic effect is usually overshadowed by central sympathetic stimulation. HR and BP rise were similar between S(+)ketamine and racemic mixture. Systemic blood pressure, heart rate, cardiac output, cardiac work, and myocardial oxygen requirements all are increased after IV administration of ketamine cardiovascular
Etomidate metabolism is rapidly metabolized by hydrolysis of the ethyl ester side chain to its carboxylic acid ester, resulting in a water-soluble, pharmacologically inactive compound. Hepatic microsomal enzymes and plasma esterases are responsible for this hydrolysis. Hydrolysis is nearly complete, as evidenced by recovery of < 3% of an administered dose of etomidate metabolism as
