In recent years, many women have become concerned about the safety of pharmaceutical replacement hormones for treatment of menopausal symptoms. “Bioidentical” hormone preparations, which are not approved by the FDA, are heavily promoted in popular books and on TV as alternatives; these are derivatives of soy or plant extracts, chemically modified to be structurally identical to endogenous hormones. Most FDA-approved single-entity hormones are also derivatives of soy or plant extracts and are structurally identical to hormones produced by the ovary.

Vardenafil (Levitra -Bayer) is the second oral drug approved by the FDA for treatment of erectile dysfunction. Sildenafil (Viagra - Medical Letter 1998; 40:51), the first oral drug, has been available for 5 years. Pharmacokinetics, effectiveness, adverse effects, dosage and cost of the new drug are reviewed. Whether it offers any benefits over sildenafil is discussed.

Olopatadine 0.6% nasal spray (Patanase - Alcon) has been approved by the FDA for treatment of seasonal allergic rhinitis in patients ≥ 12 years old. An H1-antihistamine with mast-cell stabilizing activity, olopatadine is already marketed for treatment of allergic conjunctivitis in a 0.1% solution as Patanol and in a 0.2% solution as Pataday. Azelastine (Astelin), another H1-antihistamine with mast-cell stabilizing activity, has been available for intranasal treatment of allergic rhinitis since 1997.

The FDA has approved vedolizumab (Entyvio - Takeda), an intravenous integrin receptor antagonist, for treatment of moderate to severe ulcerative colitis or Crohn's disease in adults who have not responded to, lost response to, or cannot tolerate standard treatment. Natalizumab (Tysabri), another integrin receptor antagonist, has been available for several years for treatment of Crohn's disease and multiple sclerosis.

Cobicistat, a pharmacokinetic enhancer that boosts levels of some HIV drugs but has no antiretroviral activity of its own, is now available alone as Tybost (Gilead) and in fixed-dose combinations with the protease inhibitors atazanavir (Evotaz — BMS) and darunavir (Prezcobix — Janssen) for treatment of HIV-1 infection. Both atazanavir and darunavir have traditionally been used in combination with the CYP3A inhibitor ritonavir (Norvir) to boost their serum concentrations, but neither is available in a fixed-dose combination with ritonavir.

The FDA has approved vericiguat (Verquvo – Merck), an oral soluble guanylate cyclase (sGC) stimulator, to reduce the risk of hospitalization for heart failure and cardiovascular (CV) death following a worsening heart failure event (hospitalization for heart failure or treatment with IV diuretics as an outpatient) in patients with symptomatic chronic heart failure and left ventricular ejection fraction (LVEF) <45%. Vericiguat is the second sGC stimulator to be marketed in the US. Riociguat (Adempas), which is FDA-approved for treatment of pulmonary arterial hypertension...

The FDA has approved the selective alpha_1A-adrenergic receptor agonist oxymetazoline as a 1% cream (Rhofade – Allergan) for topical treatment of persistent facial erythema of rosacea in adults. Brimonidine, a selective alpha₂-adrenergic receptor agonist, was approved in 2013 as a 0.33% gel (Mirvaso) for the same indication. Like Mirvaso, Rhofade is not indicated for treatment of inflammatory lesions of rosacea. Oxymetazoline has been available over the counter for many years as a nasal decongestant spray (Afrin, and others).

The oral Janus kinase (JAK) inhibitor baricitinib (Olumiant – Lilly), which was previously approved by the FDA for treatment of moderately to severely active rheumatoid arthritis and treatment of COVID-19 in certain hospitalized adults, has now been approved for treatment of severe alopecia areata in adults. Baricitinib is the first systemic treatment to be approved in the US for this indication.

The FDA has approved idelalisib (Zydelig – Gilead), an oral kinase inhibitor, for use in combination with rituximab (Rituxan) for treatment of relapsed chronic lymphocytic leukemia (CLL). It is also approved as monotherapy for treatment of relapsed follicular lymphoma and relapsed small lymphocytic lymphoma (both are subtypes of indolent non-Hodgkins lymphoma) in patients who have received at least two prior systemic therapies.

Belbuca (Endo), a buccal formulation of the partial opioid agonist buprenorphine, has been approved by the FDA for management of pain severe enough to require daily, around-the-clock, long-term opioid treatment. Buprenorphine is also available as a transdermal patch (Butrans) and in a parenteral formulation (Buprenex, and generics) for treatment of pain. A sublingual formulation of buprenorphine and buccal and sublingual formulations containing buprenorphine and the opioid antagonist naloxone are approved for use as alternatives to methadone for treatment of opioid...
