Adalimumab is a recombinant human monoclonal antibody that targets tumor necrosis factor-alpha (TNF-a) - a key inflammatory cytokine involved in autoimmune and inflammatory disorders. By neutralizing TNF-a activity, Adalimumab reduces inflammation, prevents tissue damage, and improves symptoms across multiple chronic autoimmune conditions such as rheumatoid arthritis, psoriasis, Crohn?s disease, and ulcerative colitis. It is marketed globally under several brand names, including Humira?.

Aclidinium bromide is a long-acting muscarinic antagonist (LAMA) used as a maintenance bronchodilator in adults with chronic obstructive pulmonary disease (COPD). It relaxes airway smooth muscle by blocking acetylcholine at muscarinic receptors, resulting in bronchodilation and improved airflow. It is not intended for the treatment of acute bronchospasm or sudden breathing difficulties.

Acitretin is an oral systemic retinoid derived from vitamin A, primarily prescribed for severe psoriasis and keratinization disorders that are unresponsive to topical therapies. By regulating epidermal cell growth and differentiation, it normalizes the excessive skin cell turnover seen in psoriatic lesions. Acitretin is used under close medical supervision due to its potent effects and risk of teratogenicity. This guide provides comprehensive information on acitretin, including its uses, dosage, side effects, interactions, benefits, and answers to frequently asked questions.

Acetylcysteine (N-acetylcysteine, NAC) is a versatile medication and dietary supplement widely used in both acute and chronic clinical care. It serves as the antidote for acetaminophen (paracetamol) toxicity, a mucolytic agent for respiratory diseases, and a glutathione precursor supporting liver detoxification and antioxidant defense. Available in oral, inhaled, and intravenous formulations, acetylcysteine is a cornerstone therapy in hepatology, pulmonology, and critical care medicine.

Acetohydroxamic acid (AHA) is a potent urease inhibitor used in the management of chronic urinary tract infections (UTIs) and prevention of struvite (infection) stones. Urease-producing bacteria in the urinary tract generate ammonia, which raises urine pH and promotes stone formation. By inhibiting urease activity, AHA helps maintain a more acidic urinary environment, thereby preventing stone growth and recurrence of infection.
