New guidelines from The National Cholesterol Education Program recommend, as a therapeutic option, lowering treatment goals for LDL cholesterol (LDL-C) from <100 mg/dL to <70 mg/dL for patients at very high risk for coronary heart disease and from 130 mg/dL to <100 mg/dL for those at moderately high risk. A likely consequence of these recommendations is increased use of statins and use of higher doses with a concomitant increase in adverse effects.

Psoriatic arthritis is a chronic inflammatory arthropathy associated with psoriasis. A recent review found that about 20% of patients with psoriasis have psoriatic arthritis. Updated guidelines for treatment of psoriatic arthritis have recently been published.

The FDA recently warned that accidental ingestion of the antitussive benzonatate (Tessalon Perles, and others) by children less than 10 years old can be fatal.1 This widely prescribed oral agent, which has been available in the US since 1958, can also cause severe morbidity and death in older children and adults, and not only in overdosage.Benzonatate is a polyglycol derivative structurally related to procaine and tetracaine. It acts peripherally on stretch receptors in the lower respiratory tract to suppress the cough reflex. If the patient chews or sucks the liquid-filled capsules or...

The FDA recently announced changes in the labeling of the hepatitis C drugs Sovaldi (sofosbuvir) and Harvoni (sofosbuvir/ledipasvir) to warn about a risk of serious and potentially fatal bradycardia when either drug is taken with the antiarrhythmic drug amiodarone (Cordarone, and others).1 Symptomatic bradycardia was reported following initiation of treatment with Harvoni or with Sovaldi plus simeprevir (Olysio) or the investigational antiviral drug daclatasvir in 9 patients already taking amiodarone; it occurred within 24 hours of starting hepatitis C therapy in 6 patients and within 2-12...

Our article earlier this year on Drugs for Acne1 stated that the oral retinoid isotretinoin (Accutane, and others) is the most effective drug available for patients with severe nodulocystic acne, but warned that depression, suicidality, myalgia, hypertriglyceridemia, and other adverse effects can occur. One of our readers objected to our listing depression and suicidality, which are the subject of a prominent warning in the package insert, in the same sentence as indisputable side effects such as hyperlipidemia and myalgia.Depression and suicidal ideation have been reported in patients with...

The FDA has amended its Emergency Use Authorization (EUA) for Paxlovid (Pfizer), the investigational oral antiviral drug nirmatrelvir copackaged with oral ritonavir, to allow for it to be prescribed by licensed pharmacists in certain situations. Paxlovid is authorized for oral treatment of mild to moderate COVID-19 in high-risk outpatients ≥12 years old who weigh at least 40 kg. NIH guidelines list it as the treatment of choice for COVID-19 in high-risk adult outpatients.

The FDA has authorized use of the Visby Medical Women's Sexual Health Test (Visby), an at-home test available without a prescription, for detection of Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis infections in women with and without symptoms. It is the first test to become available in the US for these sexually transmitted infections (STIs) that can be performed entirely at home. Other at-home tests are available in the US for diagnosis of chlamydia, gonorrhea, and trichomoniaisis, but they require mailing a urine or blood sample to a...

(Kodak) perform clinical chemistry tests using desk-top instruments, microliter samples and postage-stamp-sized analytical slides containing dry reagents layered on clear polyester and mounted in plastic. The system requires no wet reagents, except for electrolyte determinations, and is designed to require a minimum amount of training to operate. A single analysis takes about five minutes.

Trimetrexate glucuronate (Parke-Davis), an investigational drug, is now available in the USA from the National Institute of Allergy and Infectious Diseases (NIAID) for treatment of selected AIDS patients with Pneumocystis carinii pneumonia (PCP).
