Salmeterol xinafoate (Serevent - Allen & Hanburys), a long-acting β 2 -selective adrenergic agonist for inhalation, has been approved by the US Food and Drug Administration for maintenance treatment of asthma, with or without concurrent use of inhaled corticosteroids. Salmeterol is not recommended for acute treatment of bronchospasm.

Lasers have been used in dermatology for many years. Recently, however, improvements in laser technology have led to much wider use of lasers for treatment of cosmetic skin problems.

Insulin Glargine (Lantus) is a new long-acting human insulin analog approved by the FDA for treatment of both type 1 and type 2 diabetes. Synthesized by recombinant DNA technology, it differs from human insulin at position 21 in the A-chain where asparagine is replaced by glycine and at the C-terminus of the B-chain where two arginines are added.

Bosentan (Tracleer - Actelion), a non-peptide endothelin receptor antagonist, has been approved by the FDA for oral treatment of patients who have pulmonary arterial hypertension (PAH) with symptoms of dyspnea at rest or with minimal exertion.

The FDA has approved emtricitabine/tenofovir (Truvada - Gilead) and abacavir/lamivudine (Epzicom - GSK), two new fixed-dose combinations of nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), for once-daily use in treatment of HIV infection. Two other fixed-dose NRTI combinations were previously approved for twice-daily dosing. Dual NRTI therapy is generally used in either an NNRTI (non-nucleoside reverse transcriptase inhibitor)-based or a PI (protease inhibitor)-based regimen.
