Latin American Journal of Pharmacy; vol. 27, no. 5
The solubility behaviour of drugs remains one of the most challenging aspects in formulation&#13;
development. Solid dispersions (SD) and inclusion complexes (IC) are two of the most promising strategies&#13;
to improve the oral bioavailability of poorly water soluble drugs. By reducing drug particle size to the absolute&#13;
minimum, and hence improving drug wettability, bioavailability may be significantly improved.&#13;
The basis for this popularity from a pharmaceutical standpoint, is the ability of these materials to interact&#13;
with poorly water-soluble drugs and drug candidates resulting in an increase in their apparent water solubility.&#13;
This review is intended to give a general background to the use of cyclodextrins (CD) and solid dispersions&#13;
as alternative technologies in the study of drug solubilization.

Diazepam, a benzodiazepine drug, has many therapeutic uses but little is known about the diazepam dose/plasma level ratio when the drug is administered for a long period of time. In the present study we determined plasma diazepam concentration in 26 patients receiving 5 and 10 mg/day of the drug.&#13;
A gas chromatography/electron-capture detector method was validated for diazepam quantification in plasma using an OV 17-3% in Chromosorb W 80/100 mesh column. The use of 70:30 n-hexane: dichoromethane (v/v) as extraction solvent yielded good results. The following data were obtained: linearity from 10 to 1000 ng mL–1, detection and quantification limits of 5 and 10 ng.mL–1, respectively; intra and interassay average precision of 4.6 and 7.9%, respectively, mean recovery of 80.6%. The drug remained stable in the plasma sample for at least 30 days when stored at -20 °C. The relation between dose and plasma concentration did not increase in linearity when the dose was increased.

Solubility represents a limiting factor when testing new compounds in animal experiments, since&#13;
solubilizing agents generally have pharmacological effects that can interfere with the studied substance. Vehicles&#13;
are commonly used for solubilizing certain substances including apolar and polar extracts obtained from medicinal&#13;
plants. In this study, fifteen vehicles were investigated on mice neuromuscular preparations. A known in vitro&#13;
neuroblocker myotoxin from Bothrops jararacussu venom, bothropstoxin-I, was used as a pharmacological tool&#13;
for testing the medicinal potential of apolar and polar extracts (hexane, dichloromethane, ethyl acetate and&#13;
methanol) obtained from Casearia sylvestris Sw. leaves, which in turn were used for testing their solubility and&#13;
concomitantly to produce no change on basal response of indirectly stimulated mouse phrenic nerve-diaphragm&#13;
preparations. Taken together in vitro biological system and extracts solubility, our results showed that dimethyl&#13;
sulphoxide and polyethylene glycol 400 were the better vehicles, and methanol extract solubilized on PEG 400&#13;
was the only one able to act against the paralysis induced by the myotoxin. Thus, this study points out to the relevant&#13;
role that vehicles exhibit for extracting the potential pharmacological activity of plants in a given test system.

Evaluation of D-004 effects in the uterotrophic assay in mature ovariectomized rats
Latin American Journal of Pharmacy; vol. 27, no. 5
El D-004 es un extracto lipídico del fruto de la palma real (Roystonea regia) que inhibe in vitro la 5-α-reductasa prostática, y previene la hiperplasia prostática benigna inducida con testosterona y no por dihidrotestosterona en roedores, pero sus potenciales efectos estrogénicos o antiestrogénicos no han sido aún estudiados. Este estudio evalúa si el D- 004 produce efectos estrogénicos o antiestrogénicos en roedores, empleando el ensayo uterotrófico en ratas adultas ovarectomizadas, las cuales fueron distribuidas aleatoriamente en 5 grupos experimentales, un grupo Sham o falsamente operadas y 4 grupos ovarectomizadas, los cuales recibieron el vehiculo (control), D-004, estradiol y la combinación de ambos tratamientos durante 14 días, respectivamente. La reducción en el peso del útero inducida por la ovarectomía fue prevenida por el tratamiento de estradiol, pero no por el D-004, por su parte la terapia combinada produjo el mismo efecto observado en el grupo tratado con estradiol solamente. De acuerdo a estos resultados la administración de D-004 no evidencio efectos estrogénicos ni antiestrogénicos.; D-004, a lipid extract from royal palm (Roystonea regia) fruits, has shown to inhibit prostate 5-α-reductase in vitro, and to prevent prostate hyperplasia (PH) induced with T, not with DHT, in rodents, but its potential estrogenic or antiestrogenic effects had not been studied yet. This study investigated whether D-004 produces estrogenic or antiestrogenic effects, as assessed in the uterotrophic assay in ovariectomized (ovx) rats. Rats were randomly distributed into five groups: a false-operated (sham) and four groups of ovx rats: one treated with the vehicle and three others treated with D-004, estradiol and concurrent treatment with D-004 plus estradiol, respectively. Treatments were administered for 14 days. Ovariectomy reduced significantly the uterine weight, the epithelium cell height and endometrium thickness values with respect to sham groups, effects that were significantly prevented with estradiol, but unaffected with D-004. Treatment with combined therapy produced the same effect as estradiol monotherapy. According to uterotrophic assay in ovx rats, D-004 orally given at 400 mg/kg is devoid of estrogenic/antiestrogenic activity.

Este estudio evalúa si el D- 004 produce efectos estrogénicos o antiestrogénicos en roedores, empleando el ensayo uterotrófico en ratas adultas ovarectomizadas, las cuales fueron distribuidas aleatoriamente en 5 grupos experimentales, un grupo Sham o falsamente operadas y 4 grupos ovarectomizadas, los cuales recibieron el vehiculo (control), D-004, estradiol y la combinación de ambos tratamientos durante 14 días, respectivamente. La reducción en el peso del útero inducida por la ovarectomía fue prevenida por el tratamiento de estradiol, pero no por el D-004, por su parte la terapia combinada produjo el mismo efecto observado en el grupo tratado con estradiol solamente. De acuerdo a estos resultados la administración de D-004 no evidencio efectos estrogénicos ni antiestrogénicos.

D-004, a lipid extract from royal palm (Roystonea regia) fruits, has shown to inhibit prostate 5-α-reductase in vitro, and to prevent prostate hyperplasia (PH) induced with T, not with DHT, in rodents, but its potential estrogenic or antiestrogenic effects had not been studied yet. This study investigated whether D-004 produces estrogenic or antiestrogenic effects, as assessed in the uterotrophic assay in ovariectomized (ovx) rats. Rats were randomly distributed into five groups: a false-operated (sham) and four groups of ovx rats: one treated with the vehicle and three others treated with D-004, estradiol and concurrent treatment with D-004 plus estradiol, respectively. Treatments were administered for 14 days. Ovariectomy reduced significantly the uterine weight, the epithelium cell height and endometrium thickness values with respect to sham groups, effects that were significantly prevented with estradiol, but unaffected with D-004. Treatment with combined therapy produced the same effect as estradiol monotherapy. According to uterotrophic assay in ovx rats, D-004 orally given at 400 mg/kg is devoid of estrogenic/antiestrogenic activity.</dc:description>

Pre-clinic toxicity of the repeate-dose of Origanum vulgare L. (Origanum) essential Oil in Wistar rats
Latin American Journal of Pharmacy; vol. 27, no. 5
Nas últimas décadas a propriedade inibitória dos óleos essenciais vegetais frente a Candida spp. tem sido estudada, estando a do orégano entre eles. Todavia, são escassos os trabalhos sobre a toxicidade do referido óleo. Assim, o objetivo do presente estudo foi avaliar a toxicidade do óleo essencial do Origanum vulgare administrado em ratas Wistar, adultas. Quatro grupos experimentais foram constituídos,&#13;
grupo I (óleo por via oral, n = 10); grupo II (controle oral, n = 5), grupo III, (óleo por via intra-vaginal, n =10) e grupo IV (controle intra-vaginal, n = 5). O tratamento diário foi realizado por 30 dias. Utilizou-se emulsão a 3% vol/vol do óleo essencial de O. vulgare que apresentava os seguintes constituintes: α-terpineno (4,86 %), 4-terpineol (47,95 %), α-terpineol (7,56 %), timol (8,42 %) e carvacrol (9,43 %). Ao final do&#13;
tratamento, os animais foram sacrificados, sendo realizadas necropsias. Os resultados não evidenciaram qualquer alteração macroscópica nos tecidos do trato reprodutivo e digestório, assim como em fígado, baço e rins. Nas avaliações clínicas, hematológicas e histopatológicas não foram observadas alterações. De acordo com os resultados obtidos, conclui-se que o óleo essencial do O. vulgare não causa alterações toxicológicas relevantes, quando administrado à 3% por via oral e intra-vaginal em ratas Wistar, por 30 dias.

Baccharis uncinella DC. belongs to the Asteraceae family and is included in the Spicata group. Its synonym is Baccharis&#13;
discolor Baker and it is popularly known as vassoura and vassoura-lageana in Portuguese. The phytochemical&#13;
screening has shown the presence of essential oil, flavonoids, alkaloids, cardiac glycosides and saponins.&#13;
Baccharis uncinella has presented antiviral activity against Herpes simplex type I. The volatile oil of the aerial&#13;
organs has exhibited antimicrobial action against Staphylococcus aureus, Escherichia. coli and Pseudomonas&#13;
aeruginosa. This paper has aimed to analyse the morphology and anatomy of the vegetative aerial organs of B.&#13;
uncinella, in order to supply information for the identification and differentiation of this species from other&#13;
Baccharis, as well as to expand knowledge on taxonomy of the Spicata group. The botanical material was prepared&#13;

<dc:description>Baccharis uncinella DC. belongs to the Asteraceae family and is included in the Spicata group. Its synonym is Baccharis&#13;
discolor Baker and it is popularly known as vassoura and vassoura-lageana in Portuguese. The phytochemical&#13;
screening has shown the presence of essential oil, flavonoids, alkaloids, cardiac glycosides and saponins.&#13;
Baccharis uncinella has presented antiviral activity against Herpes simplex type I. The volatile oil of the aerial&#13;
organs has exhibited antimicrobial action against Staphylococcus aureus, Escherichia. coli and Pseudomonas&#13;
aeruginosa. This paper has aimed to analyse the morphology and anatomy of the vegetative aerial organs of B.&#13;
uncinella, in order to supply information for the identification and differentiation of this species from other&#13;
Baccharis, as well as to expand knowledge on taxonomy of the Spicata group. The botanical material was prepared&#13;
according to standard light and scanning electron microscopic techniques. The morpho-anatomical characters&#13;
of the leaf and stem contribute to the identification of this species.

Effects of D-002 (Beeswax Alcohols) on lipid peroxidation in middle-aged and older subjects
Latin American Journal of Pharmacy; vol. 27, no. 5
El D-002 es una mezcla de alcoholes alifáticos primarios superiores (tetracosanol, hexacosanol, octacosanol, triacontanol, dotriacontanol, tetratriacontanol) purificada de la cera de abejas con efectos antioxidantes, cuyos efectos sobre los niveles plasmáticos de hidroperóxidos totales (OHPT) no habían sido investigados. Este estudio aleatorizado, doble ciego y controlado con placebo investigó los efectos del D-002 (50 mg/día) sobre los valores plasmáticos de OHPT y otras variables oxidativas en 56 sujetos que recibieron aleatoriamente placebo ó D-002 durante 12 semanas. D-002, no el placebo, redujo significativamente los niveles plasmáticos de malondialdehido (MDA) (22,6%) y OHPT (23,8%), y aumentó el estado antioxidante total del plasma (EAOTP) (19,7%) versus los basales y del placebo. El D-002 no afectó los indicadores de seguridad. Hubo 6 bajas (4 placebo, 2 D-002), sólo una (placebo) debida a experiencias adversas (EA). Seis sujetos (5 placebo, 1 D- 002) refirieron alguna EA. Concluyendo, el D-002 (50 mg/día) redujo significativamente los niveles plasmáticos de OHPT y MDA, aumentó el EAOTP y fue bien tolerado por los sujetos de estudio, lo que expande el conocimiento previo sobre sus efectos antioxidantes en humanos.; D-002 is a mixture of higher aliphatic alcohols (tetracosanol, hexacosanol, octacosanol, triacontanol, dotriacontanol, tetratriacontanol) purified from beeswax with antioxidant effects, whose effects on plasma total hydroxyperoxides (TOHP) had not been investigated. This randomised, double-blinded, placebo-controlled study investigated the effects of D-002 (50 mg/day) on plasma TOHP and other oxidative variables in 56 subjects who received placebo or D-002 for 12 weeks. D-002, not placebo, reduced significantly plasma malondialdehyde (MDA) (22.6%) and TOHP (23.8%), and increased plasma total antioxidant status (TAS) (19.7%) versus baseline and placebo. D-002 did not affect safety indicators. There were 6 withdrawals (4 placebo, 2 D-002), only one (placebo) due to adverse experiences (AE). Six subjects (5 placebo, 1 D-002) referred some AE. Concluding, D-002 (50 mg/day) reduced significantly plasma TOHP and MDA, increased TAS, and was well tolerated by study subjects, which expands previous knowledge on its antioxidant effects in humans.

à base de Ginkgo biloba, disponíveis no mercado brasileiro. Os resultados obtidos demonstraram&#13;
que cinco dos seis medicamentos avaliados não apresentam a composição química preconizada pela Comissão&#13;
E e, portanto, seu uso não pode ser recomendado.

The present study evaluated by HPLC the&#13;
contents of flavonoid glycosides, terpene lactones and ginkgolic acids of six herbal drug products containing&#13;
Ginkgo biloba, available on the Brazilian market, as well as their dissolution profiles. The results showed that&#13;
five of the six evaluated products do not present adequate chemical composition because the contents of their active&#13;
substances are not in accordance to the limits proposed by Commission E. Therefore, their therapeutical use&#13;
is not recommended.</dc:description>
