Hexazinone C3-cyc1ohexyl-6-(dimethylamino)-l-methyl-1,3,5-triazine-2,4(1~, 3H)-dionel in Z-cc pellets (10% active ingredient) was applied at rates of 0, 2, 4, and 8 pounds of active ingredient per acre for site preparation on clay soil in a randomized experiment in May 1980. Loblolly pine seedlings planted to the site in January 1981 were measured for diameter 3 inches above the ground, height,...

The present study was carried out to determine the effects of the seed skin extract of A. hypogaea along with active ingredient pure Resveratrol on the isolated dorsal skin melanophores of the toad Bufo melanostictus.The skin melanophores of the B. melanostictus, were assayed using the mean melanophore size index and their responses were recorded in the presence of various concentrations of the...

For patients who have difficulty swallowing, a common solution is to crush tablets or open capsules. What are the consequences of this practice? We reviewed the main evidence available using the standard Prescrire methodology. The clinical consequences for the patient of crushing tablets or opening capsules can be serious: alteration of the drug's absorption can result in sometimes fatal overdo...

Two new crystalline polymorphs and an amorphous phase of the active curcuminoid ingredient in turmeric are reported. Curcumin polymorph 2 has higher dissolution rate and better solubility than the known polymorph 1.

Washing is a key step in pharmaceutical isolation to remove the unwanted crystallization solvent (mother liquor) from active ingredient (API) filter cake. This study looks at strategies for optimal wash selection, which minimizes dissolution of API product crystals while preventing precipitation or impurities. Selection solvents avoid both these phenomena can be challenging but essential mainta...
