<p>Sustained release Carvedilol matrix tablets constituting Kollidon SR were developed in this study in an attempt to investigate the effect of release modifiers on the release profile of Carvedilol from matrix. Three matrix tablet formulations were prepared by direct compression of Kollidon SR in combination with release modifier (HPMC and Microcrystalline Cellulose) and magnesium stearate. Tablets containing only Kollidon SR with the active ingredient demonstrated a rapid rate of drug release. Incorporation of HPMC in the matrix tablet prolonged the release of drug but incorporation of Microcrystalline Cellulose showed superimposable release pattern with an initial burst effect as confirmed by mean dissolution time and Higuchi release rate data. After 7 hours of dissolution, Carvedilol release from the matrix systems were 91.42%, 83.41%, from formulation F1 and F2 respectively. Formulation F3 exhibited 100 % release at 4 hours. All the tablet formulations showed acceptable pharmaco-technical properties and complied with the in-house specifications for tablet weight variation, friability, hardness, thickness, and diameter. Prepared tablets also showed sustained release property for carvedilol. The drug release mechanism from the matrix tablets of F1 and F2 was found to be followed by Fickian and F3 by Non-Fickian mechanism.</p><p>DOI: <a href="http://dx.doi.org/10.3329/icpj.v1i8.11095">http://dx.doi.org/10.3329/icpj.v1i8.11095</a></p> <p>International Current Pharmaceutical Journal 2012, 1(8): 186-192</p>

Micronized Progesterone

The objective: was to examine the effectiveness of treatment of late miscarriage threat by micronized form of progesterone for 100 mg – 3 times a day in the form of gelatin pills and vaginal tablets with lactose. Patients and methods. Under our supervision there were 70 pregnant women with normocenosis of vagina (NCV) without extragenital pathology, which were not performed systemic or local treatment with antibacterial drugs in the last 4 weeks. Among them 25 pregnant women with TLSM treated by gelatin tablets of micronized progesterone (GTP) (group 1); 25 pregnant women with TLSM, treated by vaginal micronized progesterone tablets (VPT) (2nd group) and 20 healthy women with physiological pregnancy – PV (control group). The distribution of women in the group adhered to the principles of randomization. The age of examined women ranged from 19 to 32 years, most pregnant women were aged under 30 years (89.02%). General clinical examination was carried out according to the standard scheme according to the Order MH of Ukraine № 620. Results. During the research we have determined the colpocytologcal dynamics and state of vaginal microbiota in pregnant women with threatened late miscarriage with initial vaginal normocenosis before and after treatment whit vaginal forms of progesterone. Conclusion. The received results showed low efficiency of micronized progesterone gelatin dragee at threat of the late miscarriage that at small therapeutic effect has led to the development of vaginal dysbiosis in all surveyed. In contrast, the use of micronized progesterone vaginal tablets – the maximally rapid therapeutic effect without disturbance of vaginal normocenosis. Key words: the threat of a late miscarriage, vaginal micronized forms of progesterone.
