The U.S. FDA has approved Arazlo™ (tazarotene) lotion 0.045%, manufactured by Ortho Dermatologics. The product is indicated to provide topical treatment of acne vulgaris in patients who are at least nine years of age. Although the active ingredient has been FDA approved since 1997, Arazlo is the first tazarotene acne treatment available in a lotion form.

Acne is the most common skin condition seen in the United States, affecting up to 50 million people. It occurs when skin cells and oil become trapped in hair follicles. This can cause cysts, nodules, pimples, whiteheads, and blackheads. In some cases, the disease can be painful due to inflammatory lesions, and it can also cause scarring and significant emotional distress.

In a clinical study, Arazlo was found to have similar treatment success compared to Tazorac® (tazarotene – Allergan) Cream 0.1%, with fewer treatment-related adverse events. Only 2.9% of patients treated with Arazlo experienced an adverse event, compared to 5.6% with Tazorac. The lotion formulation may help patients tolerate Arazlo better than other tazarotene treatments due to the hydrating ingredients included in the formulation. Recommended dosing is a thin layer of Arazlo applied to affected areas once daily. Contact with the eyes, mouth, paranasal creases, and mucous membranes should be avoided.

Ortho Dermatologics plans to launch the product in the first half of 2020 but has not yet announced pricing plans.

The U.S. FDA has issued a warning that serious breathing difficulties may occur in patients who have respiratory risk factors and use the medications gabapentin or pregabalin. Risk factors include advanced age, respiratory diseases such as chronic obstructive pulmonary disease (COPD) that reduce lung function, and concomitant use with central nervous system (CNS) depressants such as antidepressants, anxiolytics, and antihistamines.

Gabapentin and pregabalin, known collectively as gabapentinoids, are FDA-approved to treat a variety of conditions such as nerve pain, seizures, and restless leg syndrome. Gabapentin is available as a brand name medication (Neurontin®, Gralise®, Horizant®) and as a generic. Pregabalin is sold under the brand names Lyrica® and Lyrica® CR. Lyrica, but not Lyrica CR, became available as a generic in 2019.

To address the potential risks involved in the use of gabapentinoids, the FDA is requiring new warnings be added to the drugs’ prescribing information. The agency has also required manufacturers to conduct new clinical trials to further evaluate the drugs’ abuse potential. The misuse and abuse of gabapentinoids in combination with opioids has increased in recent years. The use of these classes of drugs together may raise the chances of serious respiratory difficulties.

Patients or their caregivers should seek immediate medical attention in the event of serious respiratory problems, as these can be life-threatening. Signs and symptoms include dizziness, shortness of breath, confusion, extreme lethargy, unresponsiveness, and bluish skin – especially on the lips, fingers, and toes. Healthcare professionals should prescribe gabapentinoids at the lowest possible dose. They should also carefully monitor elderly patients, patients who have underlying respiratory disease, and patients who also take a CNS depressant. Patients who meet these criteria should be advised of the risks and how to identify respiratory depression.

Further information regarding the warning can be found at the FDA’s website. Patients, caregivers, and healthcare providers are encouraged to report adverse events that may be related to the use of gabapentinoids to the FDA’s MedWatch program.

The U.S. FDA has approved an expanded indication for Tiglutik® (riluzole) oral suspension, manufactured by ITF Pharma. Under the expansion, the product can now be administered via percutaneous endoscopic gastrostomy (PEG) tubes to treat amyotrophic lateral sclerosis (ALS).

ALS is a disease of the motor neurons that affects approximately 16,000 individuals in the United States. As motor neurons deteriorate and die off, the brain loses its ability to send signals to the body’s muscles. This causes progressive loss of voluntary movement, which often leads to difficulty swallowing and may necessitate the placement of a PEG tube to deliver nutrients, fluids, and medications directly to the stomach.

In a clinical study, Tiglutik oral suspension was found to be bioequivalent when administered via PEG tube compared to the previously approved oral route of administration. Recommended dosing is 50mg taken twice daily at least one hour before or two hours after a meal, with 12 hours between doses. The patient’s serum aminotransferases should be monitored before and during treatment.

Tiglutik’s active ingredient, riluzole, has been FDA approved to treat ALS since 1995.

The U.S. FDA has approved Amneal Pharmaceuticals’ generic version of Merck’s NuvaRing® (etonogestrel/ethinyl estradiol vaginal ring). Amneal’s generic will be marketed under the name EluRyng™ and is the first generic alternative to NuvaRing to become available on the U.S. market.

EluRyng is lightweight, flexible vaginal ring that releases a combination of estrogen and progestin hormones indicated for use by women to prevent pregnancy. Under the recommended dosing, the ring should be inserted into the vagina for three weeks of continuous use. After the third week, EluRyng should be removed for a ring-free interval that last seven days. A new ring must then be inserted according to the recommended dosing to continue contraception.

Patients are able to insert and remove EluRyng on their own. However, they should speak to their doctor about proper use and the best time to insert the ring, as this can vary depending on the patient’s medical history and history of contraceptive use. A black box warning cautions that women over 35 years old who smoke should not use EluRyng, as smoking increases the risk of serious cardiovascular events from combination hormonal contraceptive (CHC) use.

Amneal Pharmaceuticals has launched EluRyng at a wholesale acquisition cost of $148.32 per box, compared to $162.63 for NuvaRing.
