Present investigation deals with the preparation and evaluation of orally disintegrating tablets (ODTs) of lamotrigine using β-cyclodextrin and PVP-K30 as polymers for the preparation of solid dispersion which help in enhancement of aqueous solubility of this BCS CLASS-II drug and sodium starch glycolate (SSG) and crospovidone as a superdisintegrating agent, to reduce disintegration time. The O...

The importance of the present investigation was to formulate a bilayer-floating tablet (BFT) for captopril using direct compression technology. The release layer contained captopril and various polymers such as HPMC-K15M, PVP-K30 and Carbopol 934p, alone or in combination with the drug. HPMC, K-grade and effervescent mixture of citric acid and sodium bicarbonate formed the floating layer. The f...

Telmisartan is a potent, long-lasting, nonpeptide antagonist of the angiotensin II type-1 (AT1) receptor that is indicated for the treatment of essential hypertension. It selectively inhibits stimulation of the AT1 receptor by angiotensin II without affecting other receptor systems involved in cardiovascular regulation. Very high lipophilicity a unique feature of telmisartan coupled with a high...

The enhancement of oral bioavailability of poorly water-soluble drugs remains one of the most challenging aspects of drug development. Tadalafil a BCS class II drug is an impotence agent. It is indicated for the treatment of erectile dysfunction and is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type-5 (PDE-5).However, insolubility and poor dissolut...

The current research aims to formulate and evaluated Cinnamaldehyde transdermal patches treat diabetes. A good penetration enhancer Oleic Acid, would improve drug delivery from various polymer-based patches. Transdermal of the matrix type were made by solvent casting techniques using polymer PVP K30, HPMC K100, solvent. All prepared formulations tested for folding endurance, weight variation, t...

We have previously reported that serial truncation of the Gag p9 protein of equine infectious anemia virus (EIAV) revealed a progressive loss in replication phenotypes in transfected cells, such that a proviral mutant (E32) expressing the N-terminal 31 amino acids of p9 produced infectious virus particles similarly to parental provirus, while a proviral mutant (K30) with two fewer amino acids p...

PURPOSE To investigate the interpolymer complexation between Carbopol 934P (CP) and various grades of polyvinylpyrrolidone (PVP) (K90, K32, C15, and VA/S-630). METHODS Amount of fresh and dried CP-PVP complexes, water retaining capacity, apparent density, pH, conductivity, FTIR, swelling and adhesion strength were studied. RESULTS Interpolymer complexation occurred between CP and all the PV...

Streptomyces sp. strain K30 induces the formation of an extracellular Lcp (latex-clearing protein) during poly(cis-1,4-isoprene) degradation. To investigate the function of this enzyme in Streptomyces sp. strain K30, the lcp gene was disrupted. This was the first time that the screening for a knock out lcp mutant of Streptomyces sp. strain K30 was successful. The resulting mutant Streptomyces s...
