Brief Summary
The goal of this clinical trial is to to evaluate the safety, tolerance, and pharmacokinetic profiles of Timolol Maleate Gel in healthy Chinese adult subjects. The main questions aim to answer are:
- The pharmacokinetic endpoints: Single dose:Tmax, Cmax, etc. Multiple doses:AUC0-t, AUC0-inf, λz, t1/2, etc.
- The safety and tolerance endpoints: Physical examination, vital signs, 12-lead ECG, laboratory tests (hematology, blood biochemistry and urinalysis), adverse events, local tolerance. Researchers will compare TM gel to a placebo (a look-alike substance that contains no drug) to see if TM gel works to treat IH.

Outcome Measures
Primary Outcomes (8)
Local tolerance
Local tolerance will be evaluated by an investigator or designated evaluator (e.g., dermatologist) using the blinding method.The intensity (e.g., No evidence of irritation;Minimal erythema that is barely perceptible;Definite erythema that is readily visible and minimal edema or minimal papular response;Erythema and papules, et al) of the skin response is assessed on a 8 point scale.Other response score is assessed from "A" to "H".

Interventions
A 2-day washout phase follows 1 dose on Day 1, the subjects are applied with 0.5% timolol maleate gel one time a day during Day 3-Day 12.
A 2-day washout phase follows 1 dose on Day 1, the subjects are applied with placebo one time a day during Day 3-Day 12.
