Many drugs can cause psychiatric symptoms, but a causal connection is often difficult to establish. Psychiatric symptoms that emerge during drug treatment could also be due to the underlying illness, previously unrecognized psychopathology, or psychosocial factors. The withdrawal of some drugs can cause symptoms such as anxiety, psychosis, delirium, agitation or depression.

(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.

Berdazimer 10.3% gel (Zelsuvmi – Ligand), a first-in-class nitric oxide-releasing agent, has been approved by the FDA for topical treatment of molluscum contagiosum in patients ≥1 year old. It is the second drug to become available in the US for treatment of molluscum contagiosum and the first that can be applied by the patient or caregiver at home; cantharidin 0.7% solution (Ycanth), which is applied by a healthcare professional, was approved earlier for use in patients ≥2 years old.

The oral polymerase acidic endonuclease inhibitor baloxavir marboxil (Xofluza — Genentech) is now FDAapproved for post-exposure prophylaxis of influenza in patients ≥12 years old. Baloxavir was approved for treatment of acute uncomplicated influenza in patients ≥12 years old in 2018.1 Two neuraminidase inhibitors are FDA-approved for prophylaxis of influenza: oseltamivir (Tamiflu, and generics) in patients ≥1 year old, and zanamivir (Relenza) in patients ≥5 years old.2 Unlike oseltamivir and zanamivir, baloxavir is not FDA-approved for pre-exposure prophylaxis of...

In June 2021, the FDA approved the IV amyloid beta-directed monoclonal antibody aducanumab (Aduhelm) for treatment of Alzheimer’s disease. The approval did not restrict use of the drug to patients with mild cognitive impairment or mild dementia, which was the population enrolled in the clinical trials. Now, Biogen, with the permission of the FDA, has made an addition to the labeling of the drug that says: Treatment with Aduhelm should be initiated in patients with mild cognitive impairment or mild dementia stage of disease, the population in which treatment was initiated in clinical...

The FDA has approved a new tablet formulation of bromocriptine mesylate (Cycloset – VeroScience) for treatment of type 2 diabetes in adults. Bromocriptine (Parlodel, and others) is an ergot-derived dopamine agonist that has been used for more than 20 years to treat hyperprolactinemia, acromegaly, Parkinson’s disease and restless leg syndrome.

Nonopioid drugs can be used in the treatment of many nociceptive and neuropathic pain conditions. For severe pain, especially severe chronic cancer pain, use of opioids may be necessary. Noninvasive nonpharmacologic treatments, including physical and psychological therapies, have been shown to improve pain and function in patients with some common chronic pain conditions and are unlikely to cause serious harms. A multimodal approach to analgesic therapy can increase pain control while reducing opioid use and adverse effects.

Mesalamine (Rowasa - Reid-Rowell), probably better known as 5-aminosalicylic acid (5-ASA) and also called mesalazine in some other countries, was recently marketed in the USA as an enema for treatment of mild to moderate distal ulcerative colitis, including ulcerative proctosigmoiditis and ulcerative proctitis.

Nizatidine (Axid - Lilly), a new H2-receptor antagonist similar to cimetidine (Tagamet), ranitidine (Zantac) and famotidine (Pepcid), was recently approved by the US Food and Drug Administration for treatment of active duodenal ulcer and for maintenance therapy after healing. Cimetidine, ranitidine and famotidine are also approved for treatment of pathological hypersecretory conditions such as Zollinger- Ellison syndrome; cimetidine is approved in addition for treatment of gastric ulcers.
