Several injectable products are available for soft tissue augmentation of wrinkles and folds. These fillers are often used in conjunction with botulinum toxin type A (Botox) injections.

Mecasermin (Increlex - Tercica), which is injected subcutaneously, has been approved by the FDA for treatment of growth failure in children with severe primary insulin-like growth factor (IGF-1) deficiency. Mecasermin is recombinant human (rh) IGF-1. It has also been approved to treat children with short stature who are deficient in growth hormone (GH), but have developed neutralizing antibodies in response to GH treatment. A similar product, mecasermin rinfabate (Iplex - Insmed), that was approved by the FDA for the same indications was withdrawn from the market due to patent...

The FDA has approved subcutaneous injection of methylnaltrexone (Relistor - Wyeth/Progenics), a selective mu-opioid receptor antagonist, for treatment of opioid-induced constipation in patients with advanced illness (such as incurable cancer or end-stage chronic obstructive pulmonary disease) who are receiving palliative care.

Current guidelines recommend use of a proton pump inhibitor (PPI) to decrease the risk of gastrointestinal bleeding in patients taking clopidogrel (Plavix) with aspirin. A recent issue of The Medical Letter considered whether omeprazole (Prilosec, and others) or other PPIs could interfere with the antiplatelet effect of clopidogrel. The conclusion was that patients taking both drugs should probably continue to do so until more data became available. Several new publications require reconsideration of that recommendation.

The FDA has approved Enstilar (Leo), an aerosol foam formulation of the synthetic vitamin D₃ analog calcipotriene and the high-potency corticosteroid betamethasone dipropionate, for topical treatment of plaque psoriasis in adults. Topical ointment and suspension formulations of the same combination have been available for many years.

The FDA has approved plecanatide (Trulance – Synergy), a guanylate cyclase-C receptor agonist, for treatment of chronic idiopathic constipation (CIC) in adults. Linaclotide (Linzess), another guanylate cyclase-C receptor agonist, and lubiprostone (Amitiza), a chloride channel activator, were approved earlier for treatment of CIC in adults.

The FDA has approved revefenacin (Yupelri – Mylan/Theravance Biopharma), a long-acting antimuscarinic agent (LAMA) administered once daily by standard jet nebulizer, for maintenance treatment of chronic obstructive pulmonary disease (COPD). Revefenacin is the second nebulized LAMA to be approved for this indication; glycopyrrolate (Lonhala Magnair), which is administered twice daily with a portable handheld nebulizer, was the first.
