The insecticidal activity and residual effect of two formulations of lambdacyhalothrin were evaluated with Rhodnius prolixus; laboratory and field tests were conducted in the State of Chiapas, Mexico. The results indicate that the lethal concentrations of the active ingredient of SC (LC50 = 2.37 and LC90 = 8.5 mg, a.i./m2) were 4-8 times than those with the insecticide WP applied on R. prolixus...

In the cation of the title compound, C(22)H(24)N(3)O(4) (+)·Cl(-), an active ingredient of the anti-cancer drug also known as Tarceva, the quinazoline ring system is planar within 0.044 (3) Å. The dihedral angle formed by the mean planes of the two six-membered quinazoline rings is 3.2 (1)°. Both N-bound H atoms participate in N-H⋯Cl bonds, which link the ions into infinite chains running along...

Recently, vector-borne diseases have been resurging in endemic areas and expanding their geographic range into nonendemic areas. Such changes have refocused attention to the potential for major public health events, as naive populations are exposed to these pathogens. Personal topical repellents, recommended by the United States Centers for Disease Control and Prevention and World Health Organi...

In this Laboratory Exercise, we will determine the amount of active ingredient in a commercial face wash; Sodium Salicylate. We will accomplish this by conducting a spectrophotometric analysis of the preparation at the wavelength of maximal absorbance for this compound when complexed with Fe 3+ . The resulting absorbance measurement will be correlated against calibration standards, using Beer’s...

A new formulation of clomazone (the active ingredient in Command herbicide) was evaluated at four locations in 2010. The trade name of this product is Alert® and it was developed by Cheminova. The level of crop response and barnyardgrass control observed with Alert was similar to that of Command herbicide. Furthermore the rate structure and level of control observed by soil type appears to be t...

The paper studies the compressibility of directly compressible tableting materials with dry binders, spray-dried lactose and microcrystalline cellulose, and glyceryl dibehe nate at various concentrations. Compressibility was evaluated by means of the energy profile of compression and tensile strength of tablets. Release rate of the active ingredient, salicylic acid, from the tablets was also ex...

For locally acting drug products such as nasal aerosols and nasal sprays, therapeutic equivalence between two drug products may be established by in vitro bioequivalence studies based on measurements intended to reflect the rate and extent to which the active ingredient becomes available at the site of action. For cascade impaction or multistage liquid impinger for particle size distribution, p...

BACKGROUND As the date for the introduction of biosimilars in the United States approaches, questions remain regarding the naming, coding, and approval process for these agents that will need to be carefully considered. OBJECTIVES To (a) ascertain pharmacists' awareness of and comfort level with biosimilars and (b) determine the impact of identical or different nonproprietary names on pharmac...

This paper reports the first application of surface enhanced Raman chemical imaging on pharmaceutical tablets containing the active ingredient (API) in very low concentrations. Taking advantage of the extremely intensive Raman signals in the presence of silver colloids, image aquisition time was radically decreased. Moreover, the investigation of drug distribution below the detection limit of r...
