Sustained release film coated tablets containing dexchlorpheniramine maleate were prepared in such a structure as two-third of drug were dispersed in Eudragit RS 100 to form insoluble matrix that gradually releases drug by diffusional mechanism, the rest was dispersed in the immediate release part. The core tablets were compressed by a wet granulation process and the film coated tablets by a routine film coating process with Eudragit E suspension. The formed coated tablets have suitable technical characteristics. The third formulation with Eudragit RS- drug ratio 2:1 has got the dissolution extent and the release rate in vitro similar to those of Polaramine 6mg repetabs. They also meet the requirements invitro release rate versus time for sustained release capsules containing Chlorpheniramine maleate by USP XXIII. Therefore, these film coated tablets with dexchlorpheniramine maleate may be candidates for a sustained release dosage form

Quantitation of Metronidazole by reversed phase liquid chromatography using Supelco LC-ABZ column and a mobile phase containing an acid aqueous phase (pH Metronidazole ; Tablets

Study on some methods used to quantify berberine chloride showed that the UV measuring and volumetric titration methods did not express only amount of berberine chloride itself. It is necessary to apply high- performance liquid chromatography (HPLC) to achieve the optimal conditions for better splitting, higher accuracy…in order to apply more widely in testing products commonly in market with many components combined to berberine chloride. To find out optimal methods, which are suitable with condition of present some pharmaceutical units, it is necessary to experiment continuously methods such as UV measuring and volumetric titration,… using HPLC method to compare.

Chronic prostatitis has various symptoms and many problems in management. Recently a lipidosterolic extract of Serenoa Repens, Permixon has been reported to reveal potential antiandrogenic and anti inflammatory activities on prostate. Then we used Permixon on chronic prostatitis and following results were obtained. Permixon is administered orally in dose of 160mg., b.i.d. for 60 days in 31 cases of chronic prostatitis in 1st group, Permixon 160mg, with Cipro-floxacin 500mg, b.i.d. in 35 cases in 2nd group and Placebo 2 tablets, b.i.d. in 30 cases in 3rd group. In 1st group 36 cases(77.4%) were improved, 29 cases(82.8%) in 2nd group and 7 cases (23.3 %) of 3rd group were improved. Permixon is an effective drug in chronic prostatitis and there was no changes in laboratory findings and negligible side effects were noticed

The effect of Ha Noi College of Pharmacy producted CTK tablet containing 0.5g CTK mixed powder on bacterial utero-vaginitis was studied on 31 female married subjects aged 18-44. Chloramphenicol 0.25g tablet producted by Central pharmaceutical Factory N2 was used control. Results showed that CTK tablet manifests antibacterial effect compared with chloramphenicol in utero-vaginitis. Antibacterial effect is 65.4% by a dose of treatment (20 times of application of tablet). The effect of healing the lesion was manifested earlier than that of chateravaginitisull

The HPLC method described herein has sufficient sensitivity to determine the pharmacokinetic parameters of nifedipine in plasma. A single dose cross study was carried out in volunteers comparing the test sustained release nifedipine formulation to Adalat retard tablets. Pharmacokenetic variables were calculated from the nifedipine plasma concentration data and evaluated statistically. The results showed the test formulation to be bioequivalent to the reference tablets.

Since 1975, lidocaine has been made up in Friendship hospital with the name rythmocardyl as a dissoluble tablet in the bowels. The magistral formula and processing procedures have been studied and tested to reach the VNP II - 1994 and BP-1993 standards. The lethal dosage (LD50), the anti - ventricular fibrillation and anti-arrhythmic effects, the blood concentration of lidocaine taken orally at different times as well as the dissolution of rythmocardyl in the human body have been tested experimentally. The research have proven that lidocaine, taken orally has few side effects and is safe and effective to treat the cardiac arrhythmia, notably the ventricular extrasystoles
