The objective of this study was to determine the effect of povidone. hydroxypropyl methylcellulose, hydroxypropyl cellulose, lactose and magnesium stearate on the stability of quinapril hydrochloride. The applied HPLC method was validated by the following parameters: selectivity, precision, linearity and accuracy. Binary 1:4 mixtures of quinapril hydrochloride and selected excipients were stabl...

Data supporting individual animal therapy for papillomatous digital dermatitis (PDD) and infectious pododermatitis (IP) in cattle are available for treatment with multiple drugs in the form of randomized, prospective clinical trials conducted in naturally occurring disease with negative controls and masked subjective evaluators. In the case of PDD, these trials support the use of topical tetrac...

Lyme disease is a tick-borne infectious disease caused by the spirochete Borrelia burgdorferi. Infection in most horses appears to be subclinical. Clinical signs most commonly attributed to Lyme disease in horses include low-grade fever, stiffness and lameness in more than one limb, muscle tenderness, hyperaesthesia, swollen joints, lethargy and behavioural changes. Diagnosis is made on the bas...

copper amine oxidases (caos) catalyse the oxidative de-amination of biogenic amines which are ubiquitous compounds essential for cell growth and proliferation. the enzymes are homodimers containing both topaquinone and a cu(ii) ions as cofactors at the active site of each subunit. after extraction and purification of chickpea (cicer arietinum) amine oxidase by chromatoghraphy, km and vmax of th...

Conditions for determination of: ketotifen hydrogen fumarate, azelastine hydrochloride, dimetindene maleate and promethazine hydrochloride by densitometric method in substances and pharmaceuticals were provided. Maximum wavelenghts were: 228 nm for ketotifen hydrogen fumarate, 295 nm for azelastine hydrochloride, 265 nm for dimetindene maleate and 255 nm for promethazine hydrochloride. The limi...

The minimum inhibitory concentration (MIC) was determined for 13 antibiotics against Clostridium perfringens isolated from Brazilian piglets. The collection of isolates was performed in June to October 2010. All isolates were susceptible to amoxicillin and ceftiofur, whereas most were resistant to tetracycline and lincomycin. Avilamycin and narasin were more effective against isolates from non-...

To identify drugs that are potentially used for the treatment of COVID-19, potency 1403 FDA-approved were evaluated using a robust pseudovirus assay and candidates further confirmed by authentic SARS-CoV-2 assay. Four compounds, Clomiphene (citrate), Vortioxetine, Vortioxetine (hydrobromide) Asenapine (hydrochloride), showed potent inhibitory effects in both virus The combination (hydrochloride...
