Chemistry crystals, dec. above 190,° sol. in water Pharmacology human activity unknown but has weak activity in neurochemkal tests (Lanthorn, Searle Co, unpublished communication, Oct. 1986) Legal Status not controlled... [Pg.223]

In general the receptor nomenclature used is consistent with the recommendations of the various International Union of Pharmacology (lUPHAR) Committee on receptor nomenclature (19,20). In some cases the human receptor has been cloned. By convention, pharmacologicaUy defined receptors are shown ia capital letters cloaed receptors ia lower case letters. [Pg.518]

Phase I. This involves general testing for human pharmacology in healthy volunteers, ie, safe-dose adjustment deterrnination of absorption, metabohsm, and excretion patterns and monitoring for side effects. Usually fewer than 10 test subjects ate involved. [Pg.225]

Whereas the agreement between the values in humans and guinea pig is close, this is not always so. For example, in human and rodent 5-HT p receptors, significant pharmacological differences are conferred by a single amino acid residue. [Pg.276]

The pharmacological profile of buspirone in both animals and humans differs substantially from that of the ben2odia2epine anxiolytics. Buspirone lacks anticonvulsant, myorelaxant, and hypnotic effects. It also produces less sedation resulting in less psychomotor impairment in conjunction with... [Pg.226]

Another injectable anesthetic widely used in feline and primate practice is ketamine hydrochloride [1867-66-9]. Ketamine, a derivative of phencychdine, can be chemically classified as a cyclohexamine and pharmacologically as a dissociative agent. Analgesia is produced along with a state that resembles anesthesia but in humans has been associated with hallucinations and confusion. For these reasons, ketamine is often combined with a tranquilizer. The product is safe when used in accordance with label directions, but the recovery period may be as long as 12—24 h. [Pg.405]

Up to 80% of oral doses of ascorbic acid are absorbed in humans with intakes of less than 0.2 g of vitamin C. Absorption of pharmacological doses ranging from 0.2 g to 12 g results in an inverse relationship, with less than 20% absorption at the higher doses. A single oral dose of 3 g has been reported to approach the absorptive capacity (tissue saturation) of the human intestine. Higher blood levels can be attained by providing multiple divided vitamin C doses per day. [Pg.22]

NO is now recognized as a key neuro transmitter in humans and other animals and its biologically triggered synthesis is implicated in cardiovascular pharmacology, hypertension, impotence, immunology and other vital functions.NO and NO2 are important in... [Pg.443]

Apart from finding structures that give energy minima, most molecular mechanics packages will calculate structural features such as the surface area or the molecular volume. Quantities such as these are often used to investigate relationships between molecular structure and pharmacological activity. This field of human endeavour is called QSAR (quantitative structure and activity relations). [Pg.56]

There is thus obtained bishydroxycoumarin (3). Subsequent pharmacologic and clinical work revealed this compound to be an effective anticoagulant drug in humans. It is of note that none of the synthetic anticoagulants shows in vitro activity. Rather, these compounds owe their effect to inhibition of synthesis by the liver of one of the co-factors necessary for coagulation. [Pg.331]

The applicant should provide justification for using the racemate. Where the interconversion of the enantiomers in vivo is more rapid than the distribution and elimination rates, then use of the racemate is justified. In cases where there is no such interconversion or it is slow, then differential pharmacological effects and fate of the enantiomers may be apparent. Use of the racemate may also be justified if any toxicity is associated with the pharmacological action and the therapeutic index is the same for both isomers. For preclinical assessment, pharmacodynamic, pharmacokinetic (using enantiospecific analytical methods) and appropriate toxicological studies of the individual enantiomers and the racemate will be needed. Clinical studies on human pharmacodynamics and tolerance, human pharmacokinetics and pharma-cotherapeutics will be required for the racemate and for the enantiomers as appropriate. [Pg.326]

The pharmacological activities of the isomers should be compared in vitro and in vivo in both animals and humans. Separate toxicological evaluation of the enantiomers would not usually be required when the profile of the racemate was relatively benign but unexpected effects - especially if unusual or near-effective doses in animals or near planned human exposure - would warrant further studies with the individual isomers. [Pg.328]
