The stability of kollcoat ingredients depends on external factors, e. These peroxides not only limited to binders and disintegrants such as povidone and crospovidone but to other ingredients such as fillers, lubricants and surfactants, can also cause oxidative degradation of sensitive drugs. Please choose your country.

The stability data, as shown in Table 5, suggests that raloxifene tablets with PEG-PVA were stable over 6 month period without degradation. Portfolio Overview Focusing on your needs with platform solutions Read. Keep me logged in.

Choose your language This site is available in the following languages: Compression profiles of ascorbic acid tablets prepared from the granules prepared by fluid bed and high shear granulations; the compressions were carried out on each individual samples, hence no statistical data. For instance, wet granulation though remains widely practiced in the industry for its simplicity and easy scale up, can exert an enormous mechanical stress on the excipients caused by multiple formulation steps involving blending, mixing, granulation, drying, and sieving [4].

With increasing amounts of peroxides spiked with hydrogen peroxide the formation of N-oxide increased causing a significant loss inpotency of drug [5]. MedCrave Group is ardent to provide article reprints at an instant affordable Read more You will find the unsubscribe link at the end of each newsletter you receive.

kollicoaat Binders and their peroxide levels in raloxifene tablets. Those residual peroxides typically originate during the manufacturing process and get carried over practically in many of the excipients used in formulation. Therefore, the efforts continue to identify the appropriate excipients lacking peroxides, or having significantly low peroxides to alleviate the oxidative degradation. Taken collectively, the data suggest that PEG-PVA exceptionally performed as a wet binder in fluid bed and high shear granulations, and the compression profiles of resulting granules were similar to those obtained with copovidone, HPMC and povidone K Stability condition 3 mo.

These impurities may ie to undesired reactions and alter the efficacy of dosages with possibly adverse effects [3].

Likewise, the tablets with povidone K30 bearing the low peroxide e. Please check your mailbox for further information. As wet binderit combines powerful binding with no peroxides at all. Such processing steps can kllicoat to elevated impurity levels.

This graft copolymer with a low viscosity provides additional advantages in other applications such as instant release coating, emulsifier, wetting agent and hydrophilic pore former in sustained release tablets. Link to reset your password has been sent to your provided E-Mail ID. Thus, controlling these impurities is important in alleviating the degradants to kollicaot the shelf life of drug products.

Highly reliable, cost-effective processes that produce first-class results every time.

J Anal Pharm Res 2 3: Back to registration form. The possibilities include the kollicot of antioxidants or smart packaging to alleviate the oxidative degradation [19,20].


Please provide your registered UserId to reset your password. The oxidative degradation of highly sensitive drug as raloxifene and others alike in wet granulation can be minimized during the formulation process by use of PEG-PVA. Oxidative degradation of raloxifene. Due to its low viscosity values in aqueous solutions, easy processing in a vast process oollicoat range is assured.

In a subsequent investigation, Yarkala kollidoat al. This water-soluble film-forming agent is ideal for manufacturing instant-release coatings for solid dosage forms — and for applications such as bindingpore forming and drug layering.

Kollicoat® IR: Minimizing the Risks for Oxidative Degradation of Drugs

Binders are important ingredients of solid oral dosage formulations SODFs. Peroxides, amongst many of the impurities, remain the most challenging in drug development. Download Center Looking for application guides, technical and scientific posters, brochures or technical Information?

In addition, PEG covalently bound to polyvinyl alcohol acts as an internal plasticizer and provides a high flexibility, thus allowing the polymer to overcome the mechanical stress kolkicoat manufacturing and storage of dosage forms. Tablet kolllcoat such as tablet weight, thickness, hardness, friability, and disintegration time with PEG-PVA and povidoneK30 were evaluated and found to be comparable with both binders with the individual corresponding amounts used.
