Medical Converting and Packaging for Transdermal Delivery of Cosmeceuticals, Nutraceuticals, and Aromatherapy cosmeceuticals Medical Converting and Packaging for Transdermal Delivery of Cosmeceuticals, Nutraceuticals, and Aromatherapy The market for cosmeceuticals, nutraceuticals, and aromatherapy is rapidly expanding as the ability to deliver these items using transdermal patches is further refined. From patches for anti-aging products, to essential oils for homeopathic remedies, to vitamins and nutrients for soldiers in the battlefield, transdermal patch technology has blossomed since the introduction of the first nicotine patches decades ago. Cosmeceuticals, Nutraceuticals, and Aromatherapy Transdermal delivery became more popular in areas where design and manufacturing complexity and regulatory monitoring were less intense: cosmeceuticals, nutraceuticals, and aromatherapy. Transdermal delivery technology is becoming popular for Cosmeceuticals cosmeceuticals, nutraceuticals, and aromatherapies. What are cosmeceuticals? Most often, a cosmeceutical delivers some active ingredient through the skin, while cosmetics are more “topical” in nature. Some industry experts would like to define them as products that don’t require a prescription, but are only available from professionals such as doctors, aestheticians, healthcare professionals, and technicians. Today’s most popular cosmeceuticals include: • Teeth whiteners • Lip protection • Skincare, especially anti-aging products • Haircare • Scarless wound healing, or anti-scarring treatments www.fabrico.com Backing Nutraceuticals Drug/Adhesive Nutraceuticals can include everything from nutritional supplements to complete emergency nutritional delivery Release Liner systems for those without access to meals for a period of time, for example soldiers in the field, firefighters, miners, and astronauts. Cleavage Load Dietary and nutritional supplements benefit from transdermal delivery: Drug-in-adhesive transdermal patch designs contain a liner, adhesive, and backing. • Instant and continuous delivery to the blood stream; • Time-release delivery; Types of Transdermal Patch Designs • Delivery of the optimal dosage strength; The basic functional requirements for any transdermal delivery • No breakdown in the harsh, acidic digestive system; system include adhesion to the skin, both the initial tack and • Convenient dosage. the duration, delivery of the drug, and eventual removal from the skin without causing unnecessary irritation.

The Role of Adhesives in Transdermal Patches Selection of the correct adhesive for a transdermal patch is critical. It affects both drug delivery and the adhesion of the patch to the skin for the required time period and, ultimately, its easy and pain-free removal when the therapy is completed. The right adhesive will work with the formula/drug, the patient’s skin, and body movements that occur during normal wear. Custom formulations are often required to meet the specifics for a transdermal patch. Fabrico offers three Class 10,000 clean rooms, as well as ISO 13485 certification. Acrylic, acrylic-rubber hybrids, polyisobutylene, and styrenic rubber solutions are used for their good adhesion and ability selected to protect the adhesive, which may contain the to control the rate at which the formula/drug enters the body. formulation, until application without interacting with other components in the design.

Corrugated boxes are one of the most stable packaging forms in today’s industry. According to The Marketing Guide to the U.S. Packaging Industry, in 2004 paperboard packaging products made up 40.3% of the shipment packaging industry. Paperboard sales were more than double any other material during both 2004 and 2005. Inside of the paperboard industry, corrugated board made up 64% of all paperboard sales in 2004. According to the same source, corrugated shipping containers alone had $29.5 billion in shipments during the 2005 year. This was more than all plastic packaging material combined which totaled $26.346 billion. Not only do corrugated shipping containers dominate as distribution packages, the industry continues to grow. It is expected that the corrugated container industry will grow by 1.3% from 2005 to 2010 despite the threat from other packaging materials, such as plastics (The Marketing Guide, 2006). The properties of corrugated boxes make them valuable distribution packages and give the corrugated industry a slight advantage over other competitors. Corrugated boxes are best suited as a shipping container because of their strength to cost ratio (Jonson, 1999).

This is because of their high potency, high specificity and desirable safety profile. The majority of biological drugs are peptide- and protein-based therapeutics with poor oral bioavailability. They are normally administered by parenteral injection (with a very few exceptions). Pulmonary delivery is an attractive non-invasive alternative route of administration for local and systemic delivery of biologics with immense potential to treat various diseases, including diabetes, cystic fibrosis, respiratory viral infection and asthma, etc. The massive surface area and extensive vascularisation in the lungs enable rapid absorption and fast onset of action. Despite the benefits of pulmonary delivery, development of inhalable biological drug is a challenging task. There are various anatomical, physiological and immunological barriers that affect the therapeutic efficacy of inhaled formulations. This review assesses the characteristics of biological drugs and the barriers to pulmonary drug delivery.

Each participant was exposed to two chronic drug maintenance phases (21 mg/day nicotine transdermal patch and placebo transdermal patch). Within each drug phase, the participant received intravenous injections of placebo, cocaine (15 and 30 mg/70 kg), caffeine (200 and 400 mg/70 kg), and nicotine (1.0 and 2.0 mg/70 kg) in mixed order across days. Subjective and cardiovascular data were collected before and repeatedly after drug or placebo injection. Reinforcing effects were also assessed after each injection with a Drug vs Money Multiple-Choice Form. Intravenous cocaine produced robust dose-related increases in subjective and reinforcing effects; these effects were not altered by nicotine maintenance. Intravenous caffeine produced elevations on several subjective ratings; nicotine maintenance did not affect these ratings. Under the placebo maintenance condition, intravenous nicotine produced robust dose-related subjective effects, with maximal increases similar to the high dose of cocaine; nicotine maintenance significantly decreased the subjective and reinforcing effects of intravenous nicotine.

  • Film Processing Practices
    Film processing practices Converting thin fi lms Thinner, lighter constructions The continued push for thinner and lighter constructions has been a trend in the packaging and pressure sensitive label market for the last 20 years. With changes in the type of film used in the label face (PET vs BOPP) and continued reductions in the thickness of the PET liners, we have seen a reduction in total overall caliper of 30 to 50%. Down gauged films and liners continue to be the trend in the industry for pressure sensitive decoration. Thinner films allow for improved sustainability, increased yield and reduction in manufacturing costs and storage without sacrificing the performance requirements of the label. Thin clear films normally have the potential for improved shelf appeal as well (reducing the label profile on the container for an enhanced “no label look”.) While there are many advantages to thin films there are some best practices that should be made when converting and applying these labels. Here are some converting tips and best practices when using thin film stock. Web handling • All rollers should be clean and in good working order. • Older nip rolls should be checked to ensure that durometer (hardness) has not changed signifi cantly. It is not uncommon for nip rollers to slowly increase in durometer becoming harder and smoother, causing slippage of the thinner fi lms over time. • Anti-static devices at both rewind and unwind are recommended. • The press should be well grounded. This would include any external unwind or rewind stations. • The lowest tensions should be run while still maintaining good registration.
