Abstract:
Timolol, a nonselective β-adrenergic receptor blocker, is well-tolerated and is becoming increasingly popular in dermatology, especially in the management of infantile haemangioma (IH). Its effects are mainly due to vasoconstriction, inhibition of angiogenesis and keratinocyte migration promotion for re-epithelialization and wound healing. We review the evidence behind the use of timolol in several dermatological conditions including IH, pyogenic granulomas, Kaposi sarcoma, chronic wound healing, postsurgical wounds, acne vulgaris, rosacea, eczema and red scrotum syndrome.

Local Anesthetics: Common Agents and Their Applications
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

Drug Delivery: Miscellaneous Routes
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
