Department of Inorganic and Analytical Chemistry, School of Medicine, Lublin, Poland.

Tryptamide, either suspended in 1% methylcellulose or dissolved in polyethyleneglycol 400-ethanol-physiological salt solution (4:1:5) was administered po or ip at a dose 25 mg/kg to rats, and blood level of this drug was determined by HPLC method. The obtained results were used to construct the semilogarithmic plots of tryptamide concentration vs. time and pharmacokinetic parameters of tryptamide were calculated. We found that tryptamide undergoes fast absorption (t 1/2 = 4.92-17.5 min) and elimination (t 1/2 = 55.72-74.52 min), can reach C(max) values (11-13 microg/cm3) after 30 min, and gives AUC values in the range of 21.40-27.30 (microg x h/cm3).

D009536 Niacinamide An important compound functioning as a component of the coenzyme NAD. Its primary significance is in the prevention and/or cure of blacktongue and PELLAGRA. Most animals cannot manufacture this compound in amounts sufficient to prevent nutritional deficiency and it therefore must be supplemented through dietary intake.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000894 Anti-Inflammatory Agents, Non-Steroidal Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.
