The drugs of choice for treatment of fungal infections are listed in the table that begins on page 62. Some of the indications and dosages recommended here have not been approved by the FDA. More detailed guidelines for some of these infections are available online from the Infectious Diseases Society of America (www.idsociety.org).

Doxacurium (Nuromax - Burroughs Wellcome), a new, long-acting, nondepolarizing neuromuscular blocking agent, is now available in the USA for use as a skeletal muscle relaxant during general anesthesia and for endotracheal intubation. Although small decreases in heart rate and mean arterial pressure occur in some patients who receive doxacurium, clinical studies have found no adverse cardiovascular effects in patients with heart disease receiving up to three times the usual effective dose (CM Stoops et al, Anesthesiology, 69:365, 1988; DJ Murray et al, Anesthesiology, 69:472, 1988; RS...

Every pharmaceutical drug is a dose-dependent poison. This article describes the clinical presentation and treatment of some dangerous overdoses commonly reported in adults.

Midodrine hydrochloride (ProAmatine - Roberts), an alpha1-selective adrenergic agonist, is now available for treatment of severe symptomatic orthostatic hypotension. Other treatments for this condition include other sympathomimetics, constrictive garments, erythropoietin (Epogen; Procrit) and fludrocortisone with salt (D Robertson and TL Davis, Neurology, 45 suppl 5: S26, 1995).

The FDA has approved viloxazine extended-release capsules (Qelbree – Supernus) for treatment of attention-deficit/hyperactivity disorder (ADHD) in children 6-17 years old. Viloxazine is the second selective norepinephrine reuptake inhibitor to be approved in the US for treatment of ADHD; atomoxetine (Strattera, and generics) was approved in 2002.

Since 2007, antimicrobial prophylaxis for dental procedures has been recommended to prevent viridans group streptococcal infective endocarditis only for patients at highest risk of an adverse outcome. Limiting use to such patients does not appear to have led to an increased incidence of infective endocarditis or increased mortality due to infective endocarditis.

The FDA has approved the sodium-glucose co-transporter 2 (SGLT2) inhibitor ertugliflozin (Merck) for treatment of adults with type 2 diabetes, both alone (Steglatro) and in fixed-dose combinations with metformin (Segluromet) and sitagliptin (Steglujan). Ertugliflozin is the fourth SGLT2 inhibitor to be approved in the US. All four are available in combination with metformin and three are available in combination with a dipeptidyl peptidase-4 (DPP-4) inhibitor (see Table 3).

The FDA has approved IV amisulpride (Barhemsys – Acacia), a selective dopamine-2 and -3 (D₂/D₃) receptor antagonist, for prevention and treatment of postoperative nausea and vomiting (PONV) in adults. It is the first antiemetic to be approved for rescue treatment of PONV in patients who have symptoms despite receiving antiemetic prophylaxis. Oral formulations of amisulpride are available in Europe for treatment of schizophrenia and acute psychotic episodes.
