The FDA has approved the use of the phosphodiesterase-5 (PDE-5) inhibitor tadalafil (Cialis – Lilly) for treatment of signs and symptoms of benign prostatic hyperplasia (BPH) in men with or without erectile dysfunction. Tadalafil is approved for use under another brand name (Adcirca) for treatment of pulmonary arterial hypertension. The other PDE-5 inhibitors available in the US for treatment of erectile dysfunction (sildenafil [Viagra]; vardenafil [Levitra]) have also been reported to be effective for treatment of BPH signs and symptoms, but have not been approved for this...

The FDA has approved Quartette (Teva), an extended-cycle combination oral contraceptive containing increasing doses of the estrogen ethinyl estradiol (EE) combined with the progestin levonorgestrel (LNG).

The recent increase in deaths from heroin overdose in the US has led to renewed interest in the opioid antagonist naloxone, particularly in making it available as an intranasal spray to paramedics and possibly to relatives and close friends of heroin users. Intravenous (IV) administration is preferred, but peripheral venous access may be difficult to obtain in IV drug abusers, and exposure to their blood may be hazardous.

The FDA has approved a new formulation of glucagon (Gvoke – Xeris) for subcutaneous treatment of severe hypoglycemia in patients ≥2 years old with diabetes. Conscious patients with symptoms of hypoglycemia can take oral glucose. Glucagon is usually administered by a caregiver to an unresponsive patient. The new formulation is available in a single-use prefilled syringe (Gvoke PFS) and is expected to become available in a single-use auto-injector (Gvoke HypoPen) in 2020. Unlike previously available injectable glucagon products (Glucagon Emergency Kit, and others), Gvoke does not...

Risdiplam (Evrysdi – Genentech), a survival of motor neuron 2 (SMN2) splicing modifier, has been approved by the FDA for oral treatment of spinal muscular atrophy (SMA) in patients ≥2 months old. It is the first oral drug to be approved in the US for treatment of SMA; nusinersen (Spinraza), an intrathecally administered SMN2-directed antisense oligonucleotide, and onasemnogene abeparvovec (Zolgensma), an IV adeno-associated virus vector-based gene therapy, were approved earlier.

The investigational anti-complement component 5a (C5a) antibody vilobelimab (Gohibic – InflaRx) has been granted an FDA Emergency Use Authorization (EUA) for IV treatment of hospitalized adults with COVID-19 beginning within 48 hours after invasive mechanical ventilation (IMV) or extracorporeal membrane oxygenation (ECMO) is started. Vilobelimab is the first anti-C5a antibody to become available in the US.

The FDA has approved a new indication for prevention of anal cancer and anal intraepithelial neoplasia in both sexes for the human papillomavirus (HPV) vaccine Gardasil (Merck). This vaccine is already FDA-approved for prevention of cervical cancer and genital warts in females 9-26 years old and for prevention of genital warts in males 9-26 years old. HPV types 6 and 11 cause about 90% of genital warts. Types 16 and 18 cause more than 70% of cervical cancer and about 80% of anal cancer.1 Gardasil is highly effective in preventing infection with HPV types 6, 11, 16 and 18 in both males and...

Vinorelbine (Navelbine - Burroughs Wellcome), a semisynthetic vinca alkaloid, has been approved by the US Food and Drug Administration for parenteral use in the treatment of advanced non-small-cell lung cancer (NSCLC). Various combinations of cisplatin (Platinol), vinblastine (Velban, and others), mitomycin (Mutamycin), ifosfamide (Ifex), etoposide (VePesid) and paclitaxel (Taxol) have been used previously for this indication.

The US Food and Drug Administration (FDA) has approved 'early access' use of riluzole (Rilutek - Rh ne-Poulenc Rorer) for treatment of amyotrophic lateral sclerosis (ALS). is the first drug to become available for treatment of this condition. The premarketing supply is limited; the manufacturer (1-800-798-7425) has enough on hand to treat 3,000 of the 25,000 patients with the disease in the USA, and those 3,000 have already been selected through a lottery. Similar arrangements have been made in several European countries. Riluzole is not available commercially in any country.
